Generic Flagyl
There are currently several different generic Flagyl products available, including generic short-acting tablets and capsules. The injectable form of the medication is also available as a generic. The FDA has given all generic Flagyl drugs an "AB" rating, meaning these products are equivalent to the brand-name version.
Flagyl® (metronidazole) is a prescription antibiotic medication used to treat a variety of different infections. It is effective against certain parasites as well as many different types of anaerobic bacteria (bacteria that do not require oxygen to survive).
Brand-name Flagyl is made by Pfizer, Inc. However, several forms of Flagyl are available as generics.
Generic Flagyl is available in the following strengths and forms:
- Metronidazole 250 mg tablets
- Metronidazole 500 mg tablets
- Metronidazole 375 mg capsules.
Injectable Flagyl (given by IV) is also available in generic form. Currently, there are no generic versions of long-acting Flagyl ER tablets.
Generic Flagyl is made by several different companies, including (but not limited to):
- Teva Pharmaceuticals
- Sandoz Pharmaceuticals
- Watson Laboratories
- Pliva
- Par Pharmaceuticals.
All generic medications must undergo certain tests to compare them to brand-name medications. The U.S. Food and Drug Administration (FDA) then looks at these tests to decide if the generics are equivalent to the brand-name medications and assigns each generic a rating. An "AB" rating means that the FDA has determined that a generic medication is equivalent to a brand-name medication. All of the generic metronidazole capsules and tablets currently available have an "AB" rating, meaning they should be equivalent to Flagyl.
However, generic medications are allowed to have different inactive ingredients than the brand-name medication. This might include fillers or dyes or other ingredients that may cause problems for people with allergies or sensitivities.
