It is supplied as a pill in strengths of 200 mg and 400 mg and belongs to the nitroimidazole class of antimicrobial agents. Flagyl is primarily prescribed for anaerobic bacterial infections, certain protozoal diseases, and Clostridioides difficile-associated colitis. Secondary indications include bacterial vaginosis and trichomoniasis. --- ## Quick Reference Facts ``` **Active Ingredient** : Metronidazole **Form** : Pill - 200 mg | 400 mg **Primary Uses** : • Anaerobic bacterial infections • Amebiasis (Entamoeba histolytica) • Trichomoniasis (Trichomonas vaginalis) • Bacterial vaginosis (Gardnerella vaginalis) • C. difficile-associated colitis ``` --- ## What is Flagyl? Flagyl is the generic version of medications containing the active compound metronidazole. As a member of the nitroimidazole therapeutic class, it exerts broad-spectrum activity against obligate anaerobes and certain protozoa. The drug is manufactured by several licensed pharmaceutical companies and distributed worldwide under various brand names, including Flagyl, Metrogel, and Noritate. Generic formulations such as Flagyl provide cost-effective alternatives while meeting the same bioequivalence standards required for FDA and EMA approval. --- ## How Flagyl Works Metronidazole is a pro-drug that enters susceptible microorganisms by passive diffusion. Inside the cell, anaerobic enzymes reduce the nitro group, generating highly reactive nitro-radicals. These intermediates damage DNA, inhibit nucleic acid synthesis, and ultimately cause cell death. Because reduction relies on low-redox potential pathways that are absent in most aerobic human cells, metronidazole selectively targets anaerobic bacteria and protozoa while sparing host tissues. Pharmacokinetically, Flagyl is well absorbed from the gastrointestinal tract (≈ 80 % oral bioavailability). Peak plasma concentrations occur within 1-2 hours after ingestion. The drug is metabolized principally by hepatic oxidation and glucuronidation; about 60-80 % of the dose is excreted in urine, and the remainder in feces. The elimination half-life ranges from 6 to 8 hours in healthy adults, supporting twice-daily dosing for most indications. --- ## Conditions Treated with Flagyl - **Anaerobic bacterial infections** - Metronidazole penetrates well into abscesses and polymicrobial sites, making it effective for intra-abdominal, pelvic, skin-soft tissue, and dental infections caused by *Bacteroides* and *Clostridium* species. - **Amebic liver abscess (Entamoeba histolytica)** - A 750 mg three times daily regimen for 7-10 days eradicates the parasite and resolves hepatic lesions. - **Trichomoniasis** - A single 2-gram dose (or 500 mg twice daily for 7 days) eliminates *Trichomonas vaginalis*, relieving vaginitis and preventing transmission. - **Bacterial vaginosis** - Metronidazole 500 mg twice daily for 7 days restores normal vaginal flora by suppressing *Gardnerella* and other anaerobes. - **Clostridioides difficile-associated colitis - Oral Flagyl 500 mg three times daily for 10-14 days is recommended for mild-to-moderate disease when vancomycin is unavailable. --- ## Is Flagyl the Right Medication for You? Flagyl is most suitable for adult patients with confirmed or strongly suspected infections caused by susceptible anaerobic bacteria or protozoa. It is frequently chosen when rapid bactericidal activity is required, when the infection is located in tissues with good drug penetration, or when alternative antibiotics are contraindicated. Patients with severe hepatic impairment, known hypersensitivity to nitroimidazoles, or a history of disulfiram-like reactions should avoid Flagyl. Pregnant women in the first trimester are generally advised against use unless the benefit outweighs risk; the drug is classified as pregnancy category B by the FDA for most indications. Lactating mothers should pause breastfeeding for at least 24 hours after the last dose, as metronidazole appears in breast milk. --- ## Buying Flagyl from [our online pharmacy](https://liabilis.com/order-flagyl-online-en.html) **Why Choose Our Service?** Accessing Flagyl can be challenging when local pharmacies experience stock shortages or when insurance formularies impose high copays.

Do *not* double-dose. - **Overdose** - Symptoms may include nausea, vomiting, abdominal pain, dizziness, or seizures. - Seek emergency medical care promptly. In the United States, contact the Poison Control Center at 1-800-222-1222. - **Precautions** - Avoid alcohol during treatment and for 24 hours after the last dose to prevent a disulfiram-like reaction (flushing, tachycardia, nausea). - Do not operate heavy machinery or drive until you know how Flagyl affects you, as dizziness can occur. --- ## Safety Information ### ⚠️ Who Should Not Take Flagyl - Adults with documented hypersensitivity to metronidazole or any nitroimidazole. - Patients receiving disulfiram therapy, due to the risk of severe reactions. - Individuals with severe hepatic insufficiency (Child-Pugh class C). ### Common Side Effects - **Gastrointestinal:** Nausea, metallic taste, abdominal cramping (occurs in up to 20 % of patients). - **Neurologic:** Headache, dizziness, peripheral neuropathy with prolonged use (> 4 weeks). - **Dermatologic:** Rash or mild pruritus; usually self-limiting. Most adverse effects are mild and resolve after treatment completion. If neuropathy persists, contact your healthcare provider. ### Serious Side Effects (Seek Immediate Medical Help) - **Severe allergic reaction:** Hives, swelling of face/lips, difficulty breathing. - **Seizures or convulsions:** May indicate high serum levels or CNS toxicity. - **Hepatotoxicity:** Jaundice, dark urine, right-upper-quadrant pain. If any of these occur, discontinue Flagyl and obtain emergency medical attention. ### Drug & Food Interactions - **Alcohol:** Causes a disulfiram-like reaction; abstain during therapy and for 24 hours after. - **Warfarin:** Metronidazole can potentiate anticoagulant effect; monitor INR closely. - **Lithium:** May increase lithium levels; check serum concentrations regularly. - **Cimetidine:** Can elevate metronidazole plasma concentrations; dose adjustment may be needed. --- ## Off-Label and Investigational Uses of Flagyl - **Helicobacter pylori eradication:** Metronidazole is sometimes added to triple-therapy regimens when clarithromycin resistance is suspected. Clinical studies demonstrate comparable eradication rates, though it remains an off-label component. - **Rosacea (subantimicrobial dose):** Low-dose metronidazole (.75 % topical formulation) is approved, but oral Flagyl has been explored in refractory cases with modest benefit. - **Periodontal disease:** Some dentists prescribe metronidazole adjunctively for aggressive periodontitis; evidence suggests improved pocket depth reduction. These applications have not received formal regulatory approval for oral Flagyl, and treatment should only be undertaken under direct supervision of a qualified healthcare professional. --- ## Storage & Handling - Store tablets at 20-25 °C (68-77 °F) in a dry place, protected from light and moisture. - Keep the container tightly closed; do not freeze. - Do not use after the expiration date printed on the label. - Dispose of unused tablets through a pharmacy-take-back program or according to local hazardous waste regulations. --- ## Frequently Asked Questions **Practical Use & Lifestyle** - **Can I travel overseas with Flagyl?** Yes, but keep the medication in its original container with the prescription label visible. Some countries require a doctor’s note for import of antimicrobial agents. - **Will taking Flagyl affect my ability to drink coffee?** Caffeine does not interact with metronidazole, so moderate coffee consumption is safe. - **Is it safe to take Flagyl while on a high-protein diet?** Diet composition does not significantly alter metronidazole absorption; you may maintain your usual eating habits. **Product & Formulation Details** - **What do Flagyl tablets look like?** Flagyl 200 mg tablets are round, white, and biconvex; 400 mg tablets are oval, pink, and film-coated. - **Are there any inactive ingredients I should be aware of?** Common excipients include lactose, magnesium stearate, and microcrystalline cellulose.
