As all of the patents for Estrace (estradiol) have expired, several companies have chosen to manufacture a generic version of the drug. The generic versions are sold in three strengths: estradiol 0.5 mg, estradiol 1 mg, and estradiol 2 mg. The FDA has assigned them all an "AB" rating, meaning that these generics should be equivalent to the brand-name medication.

Is Generic Estradiol as Good as Estrace?
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 versions of Estrace currently available have an "AB" rating, meaning they should be equivalent to Estrace.
However, generic medications are allowed to have different inactive ingredients than the brand-name medication. This might include fillers, dyes, or other ingredients that may cause problems for people with allergies or sensitivities.
