Indications & Clinical Uses

  • Metronidazole is used to treat infections caused by anaerobic bacteria and certain protozoa.
  • Anaerobic bacterial infections: eradicates susceptible anaerobic organisms, reducing infection severity.
  • Bacterial vaginosis: restores normal vaginal flora by eliminating pathogenic anaerobes.
  • Trichomoniasis: eliminates Trichomonas vaginalis, relieving symptoms and preventing transmission.
  • Amoebiasis: kills Entamoeba histolytica trophozoites, treating intestinal and extra‑intestinal disease.
  • Giardiasis: clears Giardia lamblia infection, relieving gastrointestinal symptoms.
  • Clostridioides difficile infection (adjunctive therapy): used alongside standard therapy to reduce toxin production.

How It Works

  • Metronidazole enters susceptible anaerobic microorganisms and protozoa by passive diffusion. Inside the cell, the nitro group is reduced by ferredoxin‑type proteins to reactive nitro radicals. These radicals interact with DNA, causing strand breakage and loss of helical structure, and also inhibit nucleic acid synthesis, leading to cell death of the pathogen. The reduction process is oxygen‑sensitive, so aerobic cells are largely spared, providing selective toxicity toward anaerobes.

Side Effects

Metronidazole may cause a range of adverse reactions, varying from mild to severe.

Common Side Effects

  • Nausea
  • Metallic taste
  • Diarrhea
  • Headache

Serious or Rare Side Effects

  • Seizures
  • Peripheral neuropathy
  • Severe allergic reactions

Precautions & Warnings

  • When prescribing Metronidazol Generis, clinicians should consider several precautionary measures to ensure safe use.
  • Renal function: assess baseline renal function and adjust dose in severe impairment.
  • Hepatic function: monitor liver enzymes in patients with hepatic disease.
  • Alcohol consumption: avoid alcohol to prevent disulfiram‑like reaction.
  • Pregnancy: use only if potential benefit justifies risk, as safety data are limited.
  • Hypersensitivity: discontinue if signs of allergic reaction appear.
  • Store at below 25°C: keep in the original packaging, protect from moisture and heat.

Avoid Interactions

Metronidazole can interact with several medicines, affecting its efficacy or safety.

Major Interactions (Avoid)

  • Alcohol: may cause a disulfiram‑like reaction.
  • Warfarin: enhanced anticoagulant effect, increasing bleeding risk.
  • Lithium: increased lithium toxicity.
  • Rifampin: induces metabolism, reducing metronidazole efficacy.

Moderate Interactions (Monitor Closely)

  • Oral contraceptives: reduced effectiveness, consider backup method.
  • Phenytoin: altered plasma levels of both drugs.
  • Cimetidine: may increase metronidazole concentrations, monitor for toxicity.

Frequently Asked Questions

Metronidazol Generis contains metronidazole, which is prescribed to treat infections caused by susceptible anaerobic bacteria and certain protozoa. Indications include anaerobic bacterial infections, bacterial vaginosis, trichomoniasis, amoebiasis, giardiasis, and as adjunctive therapy for Clostridioides difficile infection.

Metronidazole penetrates anaerobic microorganisms and is reduced by intracellular proteins to reactive nitro radicals. These radicals damage DNA and inhibit nucleic acid synthesis, leading to cell death. The reduction is oxygen‑sensitive, so aerobic cells are largely unaffected, providing selective antimicrobial activity.

The dosage of Metronidazol Generis is individualized by the prescribing healthcare professional based on the specific infection, patient age, weight, renal and hepatic function, and other clinical factors. Patients should follow the exact regimen provided by their prescriber.

Safety data for metronidazole in pregnancy are limited, and the product is classified as having an unknown pregnancy category. It should be used only when the potential benefit outweighs any possible risk to the fetus. Breastfeeding mothers should consult their physician, as metronidazole is excreted in breast milk.

To order, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies, and procurement teams worldwide, and will request trade or institutional credentials. The sales team then replies with pricing, availability, shipping details (including any cold‑chain requirements), and necessary import documentation.

Metronidazol Generis belongs to the nitroimidazole class and offers broad activity against anaerobic bacteria and protozoa, often preferred for its oral formulation and cost‑effectiveness. Alternatives such as tinidazole have similar spectra but differ in dosing frequency, while other classes like macrolides lack activity against many anaerobes, making metronidazole a first‑line choice for the listed indications.

Store the product at temperatures below 25 °C, in its original packaging, protected from moisture and direct sunlight. Do not expose the tablets to excessive heat or humidity, and keep them out of reach of children.

Metronidazol Generis is taken orally, usually with food or a full glass of water to reduce gastrointestinal irritation. The tablet should be swallowed whole and not crushed or chewed unless specifically instructed by a healthcare professional.

Serious adverse events, though rare, include seizures, peripheral neuropathy, and severe allergic reactions such as Stevens‑Johnson syndrome or anaphylaxis. Patients should seek immediate medical attention if they experience neurological symptoms, rash, or signs of hypersensitivity.

Metronidazol Generis should be avoided in individuals with a known hypersensitivity to metronidazole or other nitroimidazole compounds. Caution is also advised for patients with severe hepatic or renal impairment, and it should not be used concomitantly with alcohol due to the risk of a disulfiram‑like reaction.
