Therapeutic classView
Amoebicides, Anti-diarrhoeal Antiprotozoal
PharmacologyView
Metronidazole is a member of the imidazole class of antibacterial drug and is classified therapeutically as an antiprotozoal agent. The 5-nitro group of Metronidazole is reduced by anaerobes metabolically. Studies have demonstrated that the reduced form of this drug interacts with DNA and gives bactericidal action of Metronidazole.

Vaginal Gel:
The recommended dose is one applicator full of Metronidazole gel (approximately 5 grams containing approximately 37.5 mg of Metronidazole) intravaginally once or twice a day for 5 days. For once a day dosing, Metronidazole gel should be administered at bedtime.
Suppository:
Anaerobic Infections-- Adults: 1 g every 8 hours for 3 days, then 1 g every 12 hours.
- Children: 5-10 years: 500 mg every 8 hours for 3 days, then every 12 hours, Over 10 years adult dose.
- Adults: 1 g 2 hours before surgery; up to 3 further doses of 1 g may be given every 8 hours for high risk procedures.
- Children: 5-10 years: 500 mg 2 hours before surgery; up to 3 further doses of 500 mg may be given every 8 hours for high risk procedures.
IV Infusion:
Metronidazole intravenous infusion requires no dilution and should not be mixed with any other drugs prior to administration.- Adults and children over 12 years: Infuse 500 mg 8 hourly at a rate of 5 ml/minute and a maximum of 4 g should not be exceeded during a 24-hour period. Treatment for 7 days is sufficient for most patients, but treatment can be extended, especially for cases where reinfection is likely. For surgical prophylaxis, administration shortly before surgery should be followed by 8-hourly doses for the next 24 hours.
- Children under 12 years: 7.5 mg/kg body weight/day every 8 hours at a rate of 5 ml/minute.
Side effectsView
Metallic taste, nausea, vomiting, diarrhoea, drowsiness, rashes may be observed during treatment.
ContraindicationsView
Metronidazole is contraindicated in patients with a history of hypersensitivity to Metronidazole or other Nitroimidazole derivatives.
PrecautionsView
- If for compelling reasons, metronidazole must be administered longer than the usually recommended duration, it is recommended that hematological tests, especially leucocyte count should be carried out regularly and that patients should be monitored for adverse reactions such as peripheral or central neuropathy (such as paresthesia, ataxia, dizziness, convulsive seizures).
- Metronidazole should be administered with caution to patients with hepatic encephalopathy.
- Patients should be warned that metronidazole may darken urine.
InteractionsView
- Disulfiram: Psychotic reactions have been reported in patients who were using metronidazole and disulfiram concurrently.
- Alcohol: Alcoholic beverages and drugs containing alcohol should not be consumed during therapy and for at least one day afterwards because of the possibility of a disulfiram-like (antabuse effect) reaction (flushing, vomiting, tachycardia). Oral anticoagulant therapy (warfarin type): Potentiation of the anticoagulant effect and increased hemorrhagic risk caused by decreased hepatic catabolism. In case of co-administration, prothrombin time should be more frequently monitored and anticoagulant therapy adjusted during treatment with metronidazole.
- Lithium: Plasma levels of lithium may be increased by metronidazole.
- Cyclosporin: Serum cyclosporin and serum creatinine should be closely monitored when co-administration is necessary.
- Phenytoin or phenobarbital: increased elimination of metronidazole resulting in reduced plasma levels.
- 5-Fluorouracil: Reduced clearance of 5-fluorouracil resulting in increased toxicity of 5-fluorouracil.
- Busulfan: Plasma levels of busulfan may be increased by metronidazole, which may lead to severe busulfan toxicity.
Pregnancy & lactationView
US FDA Pregnancy Category of Metronidazole is B. There are, however, no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed. Metronidazole have been shown to be excreted in human milk. So, caution should be exercised when Metronidazole is administered to a nursing woman.
Pediatric usageView
Hepatic impairment: Metronidazole is mainly metabolised by hepatic oxidation. Substantial impairment of metronidazole clearance may occur in the presence of advanced hepatic insufficiency. Significant cumulation may occur in patients with hepatic encephalopathy and the resulting high plasma concentrations of metronidazole may contribute to the symptoms of the encephalopathy. Metronidazole should therefore, be administered with caution to patients with hepatic encephalopathy. The daily dosage should be reduced to one third and may be administered once daily. Patients should be warned that metronidazole may darken urine.
Renal impairment: The elimination half-life of metronidazole remains unchanged in the presence of renal failure. The dosage of metronidazole therefore needs no reduction. Such patients however retain the metabolites of metronidazole. The clinical significance of this is not known at present. In patients undergoing haemodialysis metronidazole and metabolites are efficiently removed during an eight hour period of dialysis. Metronidazole should therefore be re-administered immediately after haemodialysis. No routine adjustment in the dosage of Metronidazole need be made in patients with renal failure undergoing intermittent peritoneal dialysis (IDP) or continuous ambulatory peritoneal dialysis (CAPD).

Overdose effectsView
Single oral doses of metronidazole, up to 12 g have been reported in suicide attempts and accidental overdoses. Symptoms were limited to vomiting, ataxia and slight disorientation. There is no specific antidote for metronidazole overdosages. In case of suspected massive overdosages, a symptomatic and supportive treatment should be instituted.

- If for compelling reasons, metronidazole must be administered longer than the usually recommended duration, it is recommended that hematological tests, especially leucocyte count should be carried out regularly and that patients should be monitored for adverse reactions such as peripheral or central neuropathy (such as paresthesia, ataxia, dizziness, convulsive seizures).
- Metronidazole should be administered with caution to patients with hepatic encephalopathy.
- Patients should be warned that metronidazole may darken urine.
InteractionsView
- Disulfiram: Psychotic reactions have been reported in patients who were using metronidazole and disulfiram concurrently.
- Alcohol: Alcoholic beverages and drugs containing alcohol should not be consumed during therapy and for at least one day afterwards because of the possibility of a disulfiram-like (antabuse effect) reaction (flushing, vomiting, tachycardia). Oral anticoagulant therapy (warfarin type): Potentiation of the anticoagulant effect and increased hemorrhagic risk caused by decreased hepatic catabolism. In case of co-administration, prothrombin time should be more frequently monitored and anticoagulant therapy adjusted during treatment with metronidazole.
- Lithium: Plasma levels of lithium may be increased by metronidazole.
- Cyclosporin: Serum cyclosporin and serum creatinine should be closely monitored when co-administration is necessary.
- Phenytoin or phenobarbital: increased elimination of metronidazole resulting in reduced plasma levels.
- 5-Fluorouracil: Reduced clearance of 5-fluorouracil resulting in increased toxicity of 5-fluorouracil.
- Busulfan: Plasma levels of busulfan may be increased by metronidazole, which may lead to severe busulfan toxicity.
Pregnancy & lactationView
US FDA Pregnancy Category of Metronidazole is B. There are, however, no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed. Metronidazole have been shown to be excreted in human milk. So, caution should be exercised when Metronidazole is administered to a nursing woman.
Pediatric usageView
Hepatic impairment: Metronidazole is mainly metabolised by hepatic oxidation. Substantial impairment of metronidazole clearance may occur in the presence of advanced hepatic insufficiency. Significant cumulation may occur in patients with hepatic encephalopathy and the resulting high plasma concentrations of metronidazole may contribute to the symptoms of the encephalopathy. Metronidazole should therefore, be administered with caution to patients with hepatic encephalopathy. The daily dosage should be reduced to one third and may be administered once daily. Patients should be warned that metronidazole may darken urine.
Renal impairment: The elimination half-life of metronidazole remains unchanged in the presence of renal failure. The dosage of metronidazole therefore needs no reduction. Such patients however retain the metabolites of metronidazole. The clinical significance of this is not known at present. In patients undergoing haemodialysis metronidazole and metabolites are efficiently removed during an eight hour period of dialysis. Metronidazole should therefore be re-administered immediately after haemodialysis. No routine adjustment in the dosage of Metronidazole need be made in patients with renal failure undergoing intermittent peritoneal dialysis (IDP) or continuous ambulatory peritoneal dialysis (CAPD).

Overdose effectsView
Single oral doses of metronidazole, up to 12 g have been reported in suicide attempts and accidental overdoses. Symptoms were limited to vomiting, ataxia and slight disorientation. There is no specific antidote for metronidazole overdosages. In case of suspected massive overdosages, a symptomatic and supportive treatment should be instituted.

Metrocin
Indomethacin (Oral)
Indications
Rheumatoid arthritis
Indication detailsView
Indomethacin is indicated in-
- Rheumatoid arthritis
- Ankylosing spondylitis
- Osteoarthritis (degenerative joint disease)
- Gout
- Acute non-articular rheumatism (bursitis, synovitis, tendinitis).
Therapeutic classView
Drugs for Osteoarthritis, Drugs used for Rheumatoid Arthritis, Non-steroidal Anti-inflammatory Drugs (NSAIDs)
PharmacologyView
Indomethacin is NSAID having property of antipyretic and analgesic effect. A great number of pharmacological studies have proved that Indomethacin has strong anti-inflammatory, analgesic, and antipyretic properties. Unlike the corticosteriods, the effect of Indomethacin is not related to the pituitary gland or the adrenals. Indomethacin is absorbed promptly following oral administration and peak plasma levels occur within 2 hours. Approximately two thirds of this amount is excreted in the urine and the remainder is excreted in the feces. About 90% of a single dose is excreted in 24-48 hours. In a number of controlled clinical trials, Indomethacin has proved to be of great value in the treatment of rheumatic diseases, It relieves pain, reduces joints swelling edema and improves joint mobility.
DosageView
75 mg sustained-release capsule:
- Rheumatoid arthritis, ankylosing spondylitis, and osteoarthritis (degenerative joint disease): The initial dose is 75 mg sustained-release capsule once daily. If severe then twice daily is required.
- Acute attacks of gout: May control with a dose of 75 mg sustained-release capsule twice daily.
- Acute non-articular rheumatism (bursitis, synovitis, tendinitis): 1-2 sustained-release capsule daily according to the severity of this case.
- Rheumatic diseases: 50-200 mg daily in divided doses
- Acute gout: 150-200 mg daily in divided doses
- Dysmenorrhea: up to 75 mg daily
Side effectsView
Headaches, usually in the morning and kild vertigo may occur during the early weeks of therapy. These symptoms are transient and usually disappear with continued use or by reduction of the dose. Rare case of mild psychic disturbances was also reported which subsided after few days of treatment, Gastrointestinal reactions such as nausea, vomiting, diarrhoea, epigastric and abdominal pain are often due to large doses of the drug and disappear when the dose is reduced. Administration of the capsule immediately after meals with an antacid it necessary, minimize the frequency and the severity of these untoward effects.
ContraindicationsView
Indomethacin is contraindicated in patients with ulcer, gastritis, active ulcerative colitis, and it should be used with caution in patients with a history of these disorders. In these cases, administration of Indomethacin suppositories should be preferred. It is also contraindicated in the previously hypersensitive patients.
PrecautionsView
Indomethacin capsule should be used with caution with psychiatric problems, epilepsy or parkinsonism since the drug may aggravate these conditions. It is not recommended for pregnant women, because at the present time clinical studies are insufficient. Indomethacin is not given nomally in neonates except when used to assist closure of a patent ductus arteriosus.
InteractionsView
It may interact with anticoagulants, Lithium, diuretics, antihypertensive drugs, diflunisal and sulfonylureas.

Significant cumulation may occur in patients with hepatic encephalopathy and the resulting high plasma concentrations of metronidazole may contribute to the symptoms of the encephalopathy. Metronidazole should therefore, be administered with caution to patients with hepatic encephalopathy. The daily dosage should be reduced to one third and may be administered once daily. Patients should be warned that metronidazole may darken urine.
Renal impairment: The elimination half-life of metronidazole remains unchanged in the presence of renal failure. The dosage of metronidazole therefore needs no reduction. Such patients however retain the metabolites of metronidazole. The clinical significance of this is not known at present. In patients undergoing haemodialysis metronidazole and metabolites are efficiently removed during an eight hour period of dialysis. Metronidazole should therefore be re-administered immediately after haemodialysis. No routine adjustment in the dosage of Metronidazole need be made in patients with renal failure undergoing intermittent peritoneal dialysis (IDP) or continuous ambulatory peritoneal dialysis (CAPD).

Overdose effectsView
Single oral doses of metronidazole, up to 12 g have been reported in suicide attempts and accidental overdoses. Symptoms were limited to vomiting, ataxia and slight disorientation. There is no specific antidote for metronidazole overdosages. In case of suspected massive overdosages, a symptomatic and supportive treatment should be instituted.

Therapeutic classView
Amoebicides, Anti-diarrhoeal Antiprotozoal
PharmacologyView
Metronidazole is a member of the imidazole class of antibacterial drug and is classified therapeutically as an antiprotozoal agent. The 5-nitro group of Metronidazole is reduced by anaerobes metabolically. Studies have demonstrated that the reduced form of this drug interacts with DNA and gives bactericidal action of Metronidazole.

Vaginal Gel:
The recommended dose is one applicator full of Metronidazole gel (approximately 5 grams containing approximately 37.5 mg of Metronidazole) intravaginally once or twice a day for 5 days. For once a day dosing, Metronidazole gel should be administered at bedtime.
Suppository:
Anaerobic Infections-- Adults: 1 g every 8 hours for 3 days, then 1 g every 12 hours.
- Children: 5-10 years: 500 mg every 8 hours for 3 days, then every 12 hours, Over 10 years adult dose.
- Adults: 1 g 2 hours before surgery; up to 3 further doses of 1 g may be given every 8 hours for high risk procedures.

Treatment for 7 days is sufficient for most patients, but treatment can be extended, especially for cases where reinfection is likely. For surgical prophylaxis, administration shortly before surgery should be followed by 8-hourly doses for the next 24 hours.
- Children under 12 years: 7.5 mg/kg body weight/day every 8 hours at a rate of 5 ml/minute.
Side effectsView
Metallic taste, nausea, vomiting, diarrhoea, drowsiness, rashes may be observed during treatment.
ContraindicationsView
Metronidazole is contraindicated in patients with a history of hypersensitivity to Metronidazole or other Nitroimidazole derivatives.
PrecautionsView
- If for compelling reasons, metronidazole must be administered longer than the usually recommended duration, it is recommended that hematological tests, especially leucocyte count should be carried out regularly and that patients should be monitored for adverse reactions such as peripheral or central neuropathy (such as paresthesia, ataxia, dizziness, convulsive seizures).
- Metronidazole should be administered with caution to patients with hepatic encephalopathy.
- Patients should be warned that metronidazole may darken urine.
InteractionsView
- Disulfiram: Psychotic reactions have been reported in patients who were using metronidazole and disulfiram concurrently.
- Alcohol: Alcoholic beverages and drugs containing alcohol should not be consumed during therapy and for at least one day afterwards because of the possibility of a disulfiram-like (antabuse effect) reaction (flushing, vomiting, tachycardia). Oral anticoagulant therapy (warfarin type): Potentiation of the anticoagulant effect and increased hemorrhagic risk caused by decreased hepatic catabolism. In case of co-administration, prothrombin time should be more frequently monitored and anticoagulant therapy adjusted during treatment with metronidazole.
- Lithium: Plasma levels of lithium may be increased by metronidazole.
- Cyclosporin: Serum cyclosporin and serum creatinine should be closely monitored when co-administration is necessary.
- Phenytoin or phenobarbital: increased elimination of metronidazole resulting in reduced plasma levels.
- 5-Fluorouracil: Reduced clearance of 5-fluorouracil resulting in increased toxicity of 5-fluorouracil.
- Busulfan: Plasma levels of busulfan may be increased by metronidazole, which may lead to severe busulfan toxicity.
Pregnancy & lactationView
US FDA Pregnancy Category of Metronidazole is B. There are, however, no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed. Metronidazole have been shown to be excreted in human milk. So, caution should be exercised when Metronidazole is administered to a nursing woman.

The recommended dose is one applicator full of Metronidazole gel (approximately 5 grams containing approximately 37.5 mg of Metronidazole) intravaginally once or twice a day for 5 days. For once a day dosing, Metronidazole gel should be administered at bedtime.
Suppository:
Anaerobic Infections-- Adults: 1 g every 8 hours for 3 days, then 1 g every 12 hours.
- Children: 5-10 years: 500 mg every 8 hours for 3 days, then every 12 hours, Over 10 years adult dose.
- Adults: 1 g 2 hours before surgery; up to 3 further doses of 1 g may be given every 8 hours for high risk procedures.
- Children: 5-10 years: 500 mg 2 hours before surgery; up to 3 further doses of 500 mg may be given every 8 hours for high risk procedures.
IV Infusion:
Metronidazole intravenous infusion requires no dilution and should not be mixed with any other drugs prior to administration.- Adults and children over 12 years: Infuse 500 mg 8 hourly at a rate of 5 ml/minute and a maximum of 4 g should not be exceeded during a 24-hour period. Treatment for 7 days is sufficient for most patients, but treatment can be extended, especially for cases where reinfection is likely. For surgical prophylaxis, administration shortly before surgery should be followed by 8-hourly doses for the next 24 hours.
- Children under 12 years: 7.5 mg/kg body weight/day every 8 hours at a rate of 5 ml/minute.
Side effectsView
Metallic taste, nausea, vomiting, diarrhoea, drowsiness, rashes may be observed during treatment.
ContraindicationsView
Metronidazole is contraindicated in patients with a history of hypersensitivity to Metronidazole or other Nitroimidazole derivatives.
PrecautionsView
- If for compelling reasons, metronidazole must be administered longer than the usually recommended duration, it is recommended that hematological tests, especially leucocyte count should be carried out regularly and that patients should be monitored for adverse reactions such as peripheral or central neuropathy (such as paresthesia, ataxia, dizziness, convulsive seizures).
- Metronidazole should be administered with caution to patients with hepatic encephalopathy.
- Patients should be warned that metronidazole may darken urine.
InteractionsView
- Disulfiram: Psychotic reactions have been reported in patients who were using metronidazole and disulfiram concurrently.
- Alcohol: Alcoholic beverages and drugs containing alcohol should not be consumed during therapy and for at least one day afterwards because of the possibility of a disulfiram-like (antabuse effect) reaction (flushing, vomiting, tachycardia). Oral anticoagulant therapy (warfarin type): Potentiation of the anticoagulant effect and increased hemorrhagic risk caused by decreased hepatic catabolism. In case of co-administration, prothrombin time should be more frequently monitored and anticoagulant therapy adjusted during treatment with metronidazole.
- Lithium: Plasma levels of lithium may be increased by metronidazole.
- Cyclosporin: Serum cyclosporin and serum creatinine should be closely monitored when co-administration is necessary.
- Phenytoin or phenobarbital: increased elimination of metronidazole resulting in reduced plasma levels.
- 5-Fluorouracil: Reduced clearance of 5-fluorouracil resulting in increased toxicity of 5-fluorouracil.
- Busulfan: Plasma levels of busulfan may be increased by metronidazole, which may lead to severe busulfan toxicity.
Pregnancy & lactationView
US FDA Pregnancy Category of Metronidazole is B. There are, however, no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed. Metronidazole have been shown to be excreted in human milk. So, caution should be exercised when Metronidazole is administered to a nursing woman.
Pediatric usageView
Hepatic impairment: Metronidazole is mainly metabolised by hepatic oxidation. Substantial impairment of metronidazole clearance may occur in the presence of advanced hepatic insufficiency. Significant cumulation may occur in patients with hepatic encephalopathy and the resulting high plasma concentrations of metronidazole may contribute to the symptoms of the encephalopathy. Metronidazole should therefore, be administered with caution to patients with hepatic encephalopathy. The daily dosage should be reduced to one third and may be administered once daily. Patients should be warned that metronidazole may darken urine.
Renal impairment: The elimination half-life of metronidazole remains unchanged in the presence of renal failure. The dosage of metronidazole therefore needs no reduction. Such patients however retain the metabolites of metronidazole. The clinical significance of this is not known at present. In patients undergoing haemodialysis metronidazole and metabolites are efficiently removed during an eight hour period of dialysis. Metronidazole should therefore be re-administered immediately after haemodialysis. No routine adjustment in the dosage of Metronidazole need be made in patients with renal failure undergoing intermittent peritoneal dialysis (IDP) or continuous ambulatory peritoneal dialysis (CAPD).

Overdose effectsView
Single oral doses of metronidazole, up to 12 g have been reported in suicide attempts and accidental overdoses. Symptoms were limited to vomiting, ataxia and slight disorientation. There is no specific antidote for metronidazole overdosages. In case of suspected massive overdosages, a symptomatic and supportive treatment should be instituted.

- Anaerobically infected leg ulcers and pressure sores.
- Acute dental infections due to anaerobic organisms.
- Antibiotic associated pseudomembranus colitis.
Therapeutic classView
Amoebicides, Anti-diarrhoeal Antiprotozoal
PharmacologyView
Metronidazole is a member of the imidazole class of antibacterial drug and is classified therapeutically as an antiprotozoal agent. The 5-nitro group of Metronidazole is reduced by anaerobes metabolically. Studies have demonstrated that the reduced form of this drug interacts with DNA and gives bactericidal action of Metronidazole.

Therapeutic classView
Amoebicides, Anti-diarrhoeal Antiprotozoal
PharmacologyView
Metronidazole is a member of the imidazole class of antibacterial drug and is classified therapeutically as an antiprotozoal agent. The 5-nitro group of Metronidazole is reduced by anaerobes metabolically. Studies have demonstrated that the reduced form of this drug interacts with DNA and gives bactericidal action of Metronidazole.

Vaginal Gel:
The recommended dose is one applicator full of Metronidazole gel (approximately 5 grams containing approximately 37.5 mg of Metronidazole) intravaginally once or twice a day for 5 days. For once a day dosing, Metronidazole gel should be administered at bedtime.
Suppository:
Anaerobic Infections-- Adults: 1 g every 8 hours for 3 days, then 1 g every 12 hours.
- Children: 5-10 years: 500 mg every 8 hours for 3 days, then every 12 hours, Over 10 years adult dose.
- Adults: 1 g 2 hours before surgery; up to 3 further doses of 1 g may be given every 8 hours for high risk procedures.
- Children: 5-10 years: 500 mg 2 hours before surgery; up to 3 further doses of 500 mg may be given every 8 hours for high risk procedures.
IV Infusion:
Metronidazole intravenous infusion requires no dilution and should not be mixed with any other drugs prior to administration.- Adults and children over 12 years: Infuse 500 mg 8 hourly at a rate of 5 ml/minute and a maximum of 4 g should not be exceeded during a 24-hour period. Treatment for 7 days is sufficient for most patients, but treatment can be extended, especially for cases where reinfection is likely. For surgical prophylaxis, administration shortly before surgery should be followed by 8-hourly doses for the next 24 hours.
- Children under 12 years: 7.5 mg/kg body weight/day every 8 hours at a rate of 5 ml/minute.
Side effectsView
Metallic taste, nausea, vomiting, diarrhoea, drowsiness, rashes may be observed during treatment.
ContraindicationsView
Metronidazole is contraindicated in patients with a history of hypersensitivity to Metronidazole or other Nitroimidazole derivatives.
PrecautionsView
- If for compelling reasons, metronidazole must be administered longer than the usually recommended duration, it is recommended that hematological tests, especially leucocyte count should be carried out regularly and that patients should be monitored for adverse reactions such as peripheral or central neuropathy (such as paresthesia, ataxia, dizziness, convulsive seizures).
- Metronidazole should be administered with caution to patients with hepatic encephalopathy.
- Patients should be warned that metronidazole may darken urine.
InteractionsView
- Disulfiram: Psychotic reactions have been reported in patients who were using metronidazole and disulfiram concurrently.
- Alcohol: Alcoholic beverages and drugs containing alcohol should not be consumed during therapy and for at least one day afterwards because of the possibility of a disulfiram-like (antabuse effect) reaction (flushing, vomiting, tachycardia). Oral anticoagulant therapy (warfarin type): Potentiation of the anticoagulant effect and increased hemorrhagic risk caused by decreased hepatic catabolism. In case of co-administration, prothrombin time should be more frequently monitored and anticoagulant therapy adjusted during treatment with metronidazole.
- Lithium: Plasma levels of lithium may be increased by metronidazole.
- Cyclosporin: Serum cyclosporin and serum creatinine should be closely monitored when co-administration is necessary.
- Phenytoin or phenobarbital: increased elimination of metronidazole resulting in reduced plasma levels.
- 5-Fluorouracil: Reduced clearance of 5-fluorouracil resulting in increased toxicity of 5-fluorouracil.
- Busulfan: Plasma levels of busulfan may be increased by metronidazole, which may lead to severe busulfan toxicity.
Pregnancy & lactationView
US FDA Pregnancy Category of Metronidazole is B. There are, however, no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed. Metronidazole have been shown to be excreted in human milk. So, caution should be exercised when Metronidazole is administered to a nursing woman.
Pediatric usageView
Hepatic impairment: Metronidazole is mainly metabolised by hepatic oxidation. Substantial impairment of metronidazole clearance may occur in the presence of advanced hepatic insufficiency. Significant cumulation may occur in patients with hepatic encephalopathy and the resulting high plasma concentrations of metronidazole may contribute to the symptoms of the encephalopathy. Metronidazole should therefore, be administered with caution to patients with hepatic encephalopathy. The daily dosage should be reduced to one third and may be administered once daily. Patients should be warned that metronidazole may darken urine.
Renal impairment: The elimination half-life of metronidazole remains unchanged in the presence of renal failure. The dosage of metronidazole therefore needs no reduction. Such patients however retain the metabolites of metronidazole. The clinical significance of this is not known at present. In patients undergoing haemodialysis metronidazole and metabolites are efficiently removed during an eight hour period of dialysis. Metronidazole should therefore be re-administered immediately after haemodialysis. No routine adjustment in the dosage of Metronidazole need be made in patients with renal failure undergoing intermittent peritoneal dialysis (IDP) or continuous ambulatory peritoneal dialysis (CAPD).

Metallic taste, nausea, vomiting, diarrhoea, drowsiness, rashes may be observed during treatment.
ContraindicationsView
Metronidazole is contraindicated in patients with a history of hypersensitivity to Metronidazole or other Nitroimidazole derivatives.
PrecautionsView
- If for compelling reasons, metronidazole must be administered longer than the usually recommended duration, it is recommended that hematological tests, especially leucocyte count should be carried out regularly and that patients should be monitored for adverse reactions such as peripheral or central neuropathy (such as paresthesia, ataxia, dizziness, convulsive seizures).
- Metronidazole should be administered with caution to patients with hepatic encephalopathy.
- Patients should be warned that metronidazole may darken urine.
InteractionsView
- Disulfiram: Psychotic reactions have been reported in patients who were using metronidazole and disulfiram concurrently.
- Alcohol: Alcoholic beverages and drugs containing alcohol should not be consumed during therapy and for at least one day afterwards because of the possibility of a disulfiram-like (antabuse effect) reaction (flushing, vomiting, tachycardia). Oral anticoagulant therapy (warfarin type): Potentiation of the anticoagulant effect and increased hemorrhagic risk caused by decreased hepatic catabolism. In case of co-administration, prothrombin time should be more frequently monitored and anticoagulant therapy adjusted during treatment with metronidazole.
- Lithium: Plasma levels of lithium may be increased by metronidazole.
- Cyclosporin: Serum cyclosporin and serum creatinine should be closely monitored when co-administration is necessary.
- Phenytoin or phenobarbital: increased elimination of metronidazole resulting in reduced plasma levels.
- 5-Fluorouracil: Reduced clearance of 5-fluorouracil resulting in increased toxicity of 5-fluorouracil.
- Busulfan: Plasma levels of busulfan may be increased by metronidazole, which may lead to severe busulfan toxicity.
Pregnancy & lactationView
US FDA Pregnancy Category of Metronidazole is B. There are, however, no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed. Metronidazole have been shown to be excreted in human milk. So, caution should be exercised when Metronidazole is administered to a nursing woman.
Pediatric usageView
Hepatic impairment: Metronidazole is mainly metabolised by hepatic oxidation. Substantial impairment of metronidazole clearance may occur in the presence of advanced hepatic insufficiency. Significant cumulation may occur in patients with hepatic encephalopathy and the resulting high plasma concentrations of metronidazole may contribute to the symptoms of the encephalopathy. Metronidazole should therefore, be administered with caution to patients with hepatic encephalopathy. The daily dosage should be reduced to one third and may be administered once daily. Patients should be warned that metronidazole may darken urine.
Renal impairment: The elimination half-life of metronidazole remains unchanged in the presence of renal failure. The dosage of metronidazole therefore needs no reduction. Such patients however retain the metabolites of metronidazole. The clinical significance of this is not known at present. In patients undergoing haemodialysis metronidazole and metabolites are efficiently removed during an eight hour period of dialysis. Metronidazole should therefore be re-administered immediately after haemodialysis. No routine adjustment in the dosage of Metronidazole need be made in patients with renal failure undergoing intermittent peritoneal dialysis (IDP) or continuous ambulatory peritoneal dialysis (CAPD).

Overdose effectsView
Single oral doses of metronidazole, up to 12 g have been reported in suicide attempts and accidental overdoses. Symptoms were limited to vomiting, ataxia and slight disorientation. There is no specific antidote for metronidazole overdosages. In case of suspected massive overdosages, a symptomatic and supportive treatment should be instituted.

Metrona
Metronidazole
Indications
Vaginal trichomoniasis
Indication detailsView
Metronidazole is indicated in the treatment of following diseases:
- The prevention of post-operative infections due to anaerobic bacteria (particularly species of bacteroides and anaerobic streptococci).
- The treatment of septicaemia, bacteraemia, peritonitis, brain abscess, pelvic abscess, pelvic cellulitis and post-operative wound infections caused by anaerobes.
- In the treatment of urogenital trichomoniasis.
- Bacterial vaginosis (also known as non-specific vaginitis).
- All forms of amoebiasis (intestinal, extra-intestinal disease and that of symptomless cyst passers).
- Giardiasis.
- Acute ulcerative gingivitis.
- Anaerobically infected leg ulcers and pressure sores.
- Acute dental infections due to anaerobic organisms.
- Antibiotic associated pseudomembranus colitis.
Therapeutic classView
Amoebicides, Anti-diarrhoeal Antiprotozoal
PharmacologyView
Metronidazole is a member of the imidazole class of antibacterial drug and is classified therapeutically as an antiprotozoal agent. The 5-nitro group of Metronidazole is reduced by anaerobes metabolically. Studies have demonstrated that the reduced form of this drug interacts with DNA and gives bactericidal action of Metronidazole.
