Who manufactures paxil?

Who originally made Paxil?
Paxil, the brand name for the selective serotonin reuptake inhibitor paroxetine, was first brought to market by Eli Lilly & Co. in the early 1990s. The company secured the brand name and first‑market rights through a patent on the drug’s formulation and usage [1].

Which company still sells the Paxil brand today?
Eli Lilly continues to own and market the Paxil brand in the United States and many other countries. The company holds the trademark and continues to produce the medication under the brand name for prescription use, although sales have declined since the introduction of generics [1].

Are there generic versions of Paxil available?
Yes. After the expiration of the original patents, several generic manufacturers began offering paroxetine under its chemical name. These generics are sold under various brand names such as PAXIL‑S, Paxil‑Free, and simply “paroxetine” in many markets. The generics are typically cheaper and are interchangeable with the brand‑name product when prescribed by a clinician [2].

Which companies manufacture generic paroxetine?
Multiple pharmaceutical companies produce generic paroxetine, including Teva, Mylan, and Sandoz. These firms supply the generic drug to pharmacies worldwide, and their products must meet the same safety and efficacy standards set by regulatory agencies. Because the generic market is competitive, prices can vary between manufacturers and regions [2][3].

What’s the patent status of Paxil now?
The original patents covering Paxil’s formulation and therapeutic claims have long expired, allowing generic entry. Eli Lilly still protects certain secondary patents related to specific delivery systems or new indications, but these do not prevent the sale of generic paroxetine. As of the latest available data, there are no remaining active patents that block generic manufacturers from producing paroxetine in the U.S. or Europe [4].
