Bontril PDM (short-acting) tablets are available in generic form. However, no generic versions of Bontril SR (long-acting) capsules are currently available. The FDA has assigned an "AA" rating for all generic Bontril PDM tablets, meaning they are equivalent to the brand-name medication. However, generic Bontril PDM tablets may have fillers or dyes that could cause problems in people with allergies or sensitivities.
Bontril is currently made by Valeant Pharmaceuticals. However, the patent has since expired and generic Bontril is now available.
Strengths of Generic Bontril
Generic Bontril PDM tablets come in one strength -- phendimetrazine 35 mg tablets. At this time, no other medications are equivalent to Bontril SR capsules, although there are generic slow-release phendimetrazine capsules with the same active ingredient in the same amount. For slow-release products, special tests must be performed before products are considered to be equivalent. None of the generic slow-release phendimetrazine products have passed these tests.
Who Makes Generic Bontril?
A few different companies (including Sandoz and Truxton Company, Inc.) make generic versions of Bontril PDM.
Is Generic Phendimetrazine as Good as Bontril?
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 generic versions are equivalent to the brand-name medications, and assigns a rating to each one. An "AA" rating means the FDA has determined that a generic medication is equivalent to a brand-name medication. Currently, generic phendimetrazine tablets have an "AA" rating, meaning they are considered equivalent to Bontril PDM tablets. All slow-release phendimetrazine capsules (including Bontril SR) have "BC" ratings, meaning they have not been shown to be equivalent to the brand-name medication.
Keep in mind that generic medications are allowed to have different inactive ingredients than the brand-name medication. This might include fillers, dyes, or other ingredients, which may cause problems for people with certain allergies or sensitivities.
