Glaucoma Home > Generic Combigan

There are no generic Combigan (brimonidine/timolol) products available at this time. The earliest possible date that a generic version of the medication could become available is April 2022, when the first patent expires. It's important to note that brimonidine and timolol are the active ingredients in this product, not a generic version of it.

Can I Buy Generic Combigan?

Combigan® (brimonidine/timolol) is a prescription eye drop approved for the treatment of glaucoma and high eye pressure. It contains two different active ingredients: brimonidine tartrate (which belongs to a group of medications known as alpha agonists) and timolol maleate (a beta blocker). This medicine works to lower eye pressure by decreasing fluid production in the eye and increasing fluid drainage.
Combigan is manufactured by Allergan, Inc. It is currently under the protection of a patent that prevents any generic Combigan from being manufactured in the United States.
Yet, if you search the Internet for "generic Combigan," you may find a number of companies selling it. The fact is that these medicines may be fake, substandard, and potentially dangerous. Generic Combigan may be available from another country, but there is really no way of knowing if you are getting genuine Combigan or not. Thus, you should not buy anything claiming to be generic Combigan until an approved version is available.

When Will Generic Combigan Be Available?

The first patent for Combigan currently expires in April 2022. This is the earliest predictable date that a generic version could become available. However, other circumstances could come up to extend or shorten the exclusivity period. This could include such things as lawsuits or other patents for specific Combigan uses. Once the patent expires, there may be several companies that manufacture a generic Combigan drug.
