Is Diclofenac a Generic Pennsaid?
No -- diclofenac is the active ingredient in Pennsaid (as well as several other medications), but is not a generic version of it. What can be confusing is that oftentimes, the active ingredient of any drug is referred to as the "generic name." The generic name is different from a generic version of a medicine.
In order for there to be a generic version of a medicine, the original medicine must have gone off-patent and another company besides the original manufacturer must make the product.
