Incontinence Home > Generic VESIcare

While there are currently no generic VESIcare products available, several drug companies are expected to begin manufacturing a generic version of the drug as soon as its patent expires. The first patent for VESIcare is set to expire in December 2015. Unless lawsuits or new patents come up to extend the exclusivity period beyond then, generic VESIcare should be available at that time.

Generic VESIcare: An Overview

VESIcare® (solifenacin succinate) is a prescription medication used for relieving overactive bladder symptoms. It belongs to a group of drugs known as anticholinergic medications.
VESIcare is made jointly by Astellas Pharma US, Inc. and GlaxoSmithKline. The drug is currently under the protection of a patent that prevents any generic VESIcare from being manufactured in the United States. Yet, if you search the Internet for "generic VESIcare," you may find a number of companies selling it. The fact is that these medicines may be fake, substandard, and potentially dangerous. Even if a generic version of VESIcare is available from another country, it is difficult to know if you are getting the actual medication or a counterfeit. You should not buy any generic VESIcare until there is an approved version available.

When Will Generic VESIcare Be Available?

The first patent for VESIcare currently expires in December 2015. This is the earliest possible date that a generic version of the drug could become available. However, other circumstances could come up to extend the exclusivity period beyond 2015. This could include such things as other patents for specific VESIcare uses or lawsuits. Once the patent expires, several companies will likely begin manufacturing a generic VESIcare drug.

Is Solifenacin the Same as Generic VESIcare?

No -- solifenacin is the active ingredient in VESIcare 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.
