Although no patents or exclusivity rights prevent a company from making generic Talwin (pentazocine), there are currently no generic versions available. It is unclear why this is the case. It may be because the demand for Talwin is too small for it to be profitable for a company to make a generic product.
Can I Buy Generic Talwin?
Talwin® (pentazocine lactate) is a prescription opioid medication used to treat moderate-to-severe pain. It may also be used before surgery or anesthesia.
Talwin is made by Hospira, Inc. It is not available in generic form at this time.
When Will Generic Talwin Be Available?
Talwin is a relatively older medication. It was approved by the U.S. Food and Drug Administration (FDA) before 1982. As an older medicine, it is no longer under the protection of patents or exclusivity rights. Therefore, a manufacturer could make a generic version of the drug.
However, no manufacturer has chosen to make a generic Talwin medication at this time. It is not entirely clear why this is the case. It could be that the demand for Talwin is too small to make it worthwhile for a company to make a generic version of the drug. Because it is not entirely clear why a generic version is not being made, it is difficult to predict when, or even if, such a product will become available.
Is Pentazocine a Generic Talwin?
No -- pentazocine is the active ingredient in Talwin, 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.
