Is Generic Estropipate as Good as Ogen?
All generic medications must have certain tests to compare them to brand-name medications. The U.S. Food and Drug Administration (FDA) then looks at these tests to decide whether the generics are equivalent to the brand-name medications and assigns a rating to each one. An "AB" rating means that the FDA has determined that a generic medication is equivalent to a brand-name medication. All of the generic estropipate versions currently available have an "AB" rating, meaning they should be equivalent to Ogen.
However, generic medications are allowed to have different inactive ingredients from the brand-name medication. This might include fillers, dyes, or other ingredients, which could cause problems for people with allergies or sensitivities.
