You can buy GoLYTELY (polyethylene glycol electrolyte solution) as a generic or a brand-name medication. The generic version of the laxative comes in one strength and is made by companies such as Mylan Pharmaceuticals and Novel Laboratories, Inc. The FDA has given all of the generic versions an "AA" rating, which means they are equivalent to the brand-name version.

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 "AA" rating means that the FDA does not expect there to be any problems with the generic versions being equivalent to the brand-name product. All of the generic GoLYTELY versions currently available have an "AA" rating, meaning they should be as good as GoLYTELY.
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.
