Pain Home > Generic Zipsor

There are no generic versions of Zipsor (diclofenac potassium) available on the market at this time. This is because the medication is currently under the protection of a patent that prevents any generic versions from being manufactured in the United States. Once this patent expires, a number of drug companies may begin manufacturing generic versions.

Is a Generic Version of Zipsor Available?

Zipsor™ (diclofenac potassium) is a prescription pain medication. It is a nonsteroidal anti-inflammatory drug (NSAID) and is the only form of diclofenac that comes in a liquid-filled capsule.
Zipsor is made by Xanodyne Pharmaceuticals, Inc. There are no generic forms of Zipsor available at this time.

When Will a Generic Version Be Available?

The first patent for Zipsor is currently set to expire in July 2019. This is the earliest predictable date that a generic version of Zipsor could become available. However, there are other circumstances that could come up to extend or shorten the exclusivity period of Zipsor. This could include such things as lawsuits or new Zipsor patents.

Is Diclofenac a Generic Form of Zipsor?

The answer is no. Diclofenac is the active ingredient in Zipsor (as well as several other medications) but is not a generic version of the medicine. 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.
