Because Belviq (lorcaserin) is protected by patents, companies are not allowed to make generic versions of the medication. However, after the first patent expires in April 2023, this could change, unless lawsuits or new patents are filed. Although lorcaserin is considered the "generic name" of Belviq, it is simply the active ingredient in the drug and not a generic version of it.
Can I Buy Generic Belviq?Belviq® (lorcaserin) is a prescription weight loss drug approved for people who are obese or have medical problems caused by being overweight. It should be used in combination with a reduced-calorie diet and increased physical activity.
Belviq is made by Arena Pharmaceuticals GmbH and distributed by Eisai, Inc. It is protected by patents that prevent any generic versions from being manufactured in the United States.
When Will a Generic Version Be Available?This first patent for Belviq is set to expire in April 2023. This is the earliest predictable date that a generic version could become available.
However, other circumstances could come up to extend or delay this exclusivity period. This could include such things as lawsuits or other patents for new Belviq uses. Once the patents expire, there may be several companies that manufacture a generic Belviq drug.
Is Lorcaserin a Generic Belviq?No -- lorcaserin is the active ingredient in Belviq, not a generic version of it. What can be confusing is that the active ingredient of a drug is often 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, the original medicine must have gone off-patent, and another company besides the original manufacturer must make the product.
