Metronidazole (Flagyl®, MetroCream®, MetroGel®, MetroGel-Vaginal®, MetroLotion®, Noritate®, Vandazole®) is a prescription antibiotic that comes in many different forms, including oral tablets and capsules, skin creams and lotions, and vaginal creams.
There are several different strengths available for the oral form of metronidazole: 250 mg tablets, 500 mg tablets, 750 mg long-acting tablets, and 375 mg capsules. All of the short-acting, oral forms of this medication are also available in generic form. You can take short-acting metronidazole tablets or capsules with food or on an empty stomach. However, long-acting metronidazole extended-release tablets must be taken on an empty stomach, at least one hour before or two hours after a meal.
A seven-day treatment of metronisazole 250 mg three times daily is common when treating trichomoniasis (a sexually transmitted infection).
It is important that you finish your entire prescription, even if you start feeling better, to ensure that the infection is completely treated. You should not miss doses or stop taking this antibiotic earlier than your healthcare provider recommends, as bacterial resistance may develop.
