Flagyl (Metronidazole) for Colitis: Mechanism of Action and Dosage

Metronidazole, marketed as Flagyl, combats colitis by targeting bacteria responsible for inflammation. It works by interfering with bacterial DNA synthesis, effectively killing the microbes. This reduces the inflammation causing your colitis symptoms.

Dosage Guidelines

Dosage varies depending on the severity of your colitis and your physician’s assessment. Typical adult dosages for mild to moderate colitis range from 750 mg to 1500 mg per day, divided into multiple doses. Treatment usually lasts 7-10 days. Your doctor will determine the precise dosage and duration based on your individual needs. Always follow your doctor’s instructions meticulously.

Potential Side Effects

Common side effects include nausea, vomiting, diarrhea, and metallic taste. Less frequent, but more serious, side effects can include seizures and peripheral neuropathy. Report any unusual symptoms to your healthcare provider immediately.

Drug Interactions

Flagyl interacts with certain medications, including anticoagulants like warfarin. Inform your doctor of all medications, supplements, and herbal remedies you are taking before starting Flagyl treatment to avoid potential complications.
