Apo-metronidazole is an antibiotic used to treat infection by inhibiting bacteria growth, according to WebMD. It is manufactured and sold by Pfizer, Inc. under the brand names Flagyl and Flagyl Extended Release.
According to Drugs.com, apo-metronidazole is commonly used to treat amebiasis infections, bacterial infections and trichomoniasis infections. It is also a popular treatment for bacterial vaginosis in women.
WebMD recommends that patients complete any prescribed course of apo-metronidazole, even if symptoms improve. This means the medication cannot be shared between two people with the same infections. Each person needs their own prescription. WebMD also warns patients against taking a double dose after a missed pill; instead, patients are advised to take one pill at the next scheduled dosing time.
