At this time, generic Hyzaar is available in three strengths and is manufactured by several companies. The FDA has assigned the generic version an "AB" rating, which means it is considered equivalent to brand-name Hyzaar. However, generic medications may contain different inactive ingredients, and these can cause problems for people with certain sensitivities.

Is Generic Losartan-Hydrochlorothiazide as Good as Hyzaar?
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 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 losartan-hydrochlorothiazide versions currently available have an "AB" rating, meaning they should be equivalent to Hyzaar.
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.
