Flagyl 750 mg Tablets
Flagyl® (metronidazole) is an antibiotic that is available with a prescription. It comes in the form of tablets, long-acting tablets, capsules, and injections.
Your dose of Flagyl will depend on several factors, such as your weight, other medications you are taking, and the type of infection you have. For example, the long-acting version of this medication (Flagyl 750 mg ER tablets) is only approved for treating bacterial vaginosis. Regular, short-acting Flagyl tablets and capsules are not approved for this use.
Although you can take the regular Flagyl tablets or capsules with food or on an empty stomach, the 750-mg tablets of Flagyl ER must be taken on an empty stomach, at least one hour before or two hours after a meal. It is also important to take your dosage at the same time(s) each day. Taking doses too far apart can make the drug less effective, and taking them too close together may increase the risk of side effects.
