Mefagyl: Metronidazole Suspension (200 mg/5 mL)

What it is

Mefagyl is a brand of the generic medicine metronidazole. Metronidazole is an antibiotic and antiprotozoal medication that works by stopping the growth of bacteria and other microorganisms that cause infections.

What it's used for

According to its registered information, Mefagyl is used to treat trichomoniasis, a sexually transmitted infection caused by the parasite Trichomonas vaginalis. It can be used in both women and men when the infection has been confirmed by a laboratory test.

How it's taken

Mefagyl is a liquid suspension that is taken by mouth. The exact dose and how long to take it will be decided by a doctor based on the infection being treated. It is important to follow the prescription exactly and finish the full course, even if you start to feel better.

Common side effects

Serious side effects have been reported with metronidazole, including seizures, encephalopathy (brain dysfunction), aseptic meningitis (inflammation of the brain lining), and peripheral neuropathy (numbness or tingling in the hands or feet). If you experience any numbness, tingling, or unusual symptoms, stop taking the medicine and see a doctor immediately.

Important cautions

Do not take Mefagyl if you are allergic to metronidazole or other nitroimidazole medicines. It should not be used during the first three months of pregnancy. Avoid taking it with disulfiram (a drug for alcohol dependence) because it can cause severe mental reactions. Rare but serious skin reactions, such as Stevens-Johnson syndrome, have occurred; stop the medicine and get medical help if you develop a rash or skin blisters.
