Generic Karbinal ER
You cannot buy a generic Karbinal ER (carbinoxamine extended-release oral suspension) at this time, as this medicine is protected by a patent. After this patent expires in March 2029, however, companies may be allowed to make a generic version of this allergy medicine, unless new patents or lawsuits are filed.
Can I Buy Generic Karbinal ER?
Karbinal™ ER (carbinoxamine extended-release oral suspension) is a prescription antihistamine approved to treat a variety of allergic conditions, including allergic rhinitis (nasal allergies). It comes as a long-acting liquid that is taken twice a day.
This medication is made by Tris Pharma, Inc. It is protected from generic competition by a patent that has not yet expired.
When Will a Generic Version Be Available?
The patent for Karbinal ER is set to expire in March 2029. This is the earliest predictable date that a generic version could become available.
However, other circumstances could come up to delay or shorten this exclusivity period. This could include such things as lawsuits or other patents for new Karbinal ER uses. Once the patent expires, there may be several companies that manufacture a generic Karbinal ER drug.
Is Carbinoxamine a Generic Karbinal ER?
No -- carbinoxamine is the active ingredient in Karbinal ER, 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 of a medicine, the original medicine must have gone off-patent, and another company besides the original manufacturer must make the product.
