Generic Isoptin SR

Three strengths of generic Isoptin SR are currently available, and the FDA has assigned an "AB" rating to these products. This means that these generic versions are considered equivalent to the brand-name medication. However, generic Isoptin SR has different inactive ingredients (such as fillers or dyes) than the brand-name medication, which may cause problems in people with allergies or sensitivities.

Is Generic Verapamil as Good as Isoptin SR?

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 "AB" rating means the FDA has determined that a generic medication is equivalent to a brand-name medication. All of the generic Isoptin SR versions currently available have an "AB" rating, meaning they should be equivalent to Isoptin SR. Keep in mind, however, that there are many versions of verapamil that are equivalent to other products (such as Calan® or Verelan®), but not to Calan SR.
 
In addition, 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.
