To assist you in the care of your patients, we would like to alert you to the market withdrawal of Ukoniq® 200 mg tablets on June 1, 2022.1 We recommend you review your medical records and contact all patients for whom you have prescribed this medication to warn them of the withdrawal and consider switching them to a clinically appropriate alternative.

The U.S. Food and Drug Administration (FDA) announced it has withdrawn its approval for Ukoniq due to safety concerns. Updated findings from a clinical trial showed a possible increased risk of death in patients using Ukoniq. As a result, the FDA determined the risks of treatment with Ukoniq outweigh its benefits. The drug manufacturer, TG Therapeutics, has voluntarily withdrawn the medication based on this determination.

Ukoniq is a cancer medication that was approved to treat two specific types of lymphoma: marginal zone lymphoma and follicular lymphoma.


Visit the FDA website for specific details about the withdrawn medication.
