Tanzeum® Discontinuation

July 26, 2017

On July 26, 2017, GlaxoSmithKline (GSK) announced they will stop making Tanzeum®. GSK’s decision was not related to any known safety concerns with this product. Their decision to stop making Tanzeum was because of declining sales of the product.

A completed list of products affected by this issue is available here:

GSK expects that supply of Tanzeum will be gone by May 2018. Because of this, CVS Caremark will continue to dispense Tanzeum until current supplies are used up at which time, members will need a new prescription for an alternate medicine to treat their condition.

CVS Caremark Response: Because of this action, CVS Caremark Mail Service Pharmacy is sending notification mailings to plan members that received Tanzeum to advise them of this issue. For more information, please call a Customer Care representative toll-free at 1‑866‑823‑5184.

If you are currently using Tanzeum and have questions, please call your doctor or call the GSK Customer Response Center toll-free at 1-888-825-5249 or visit

You may also call the U.S. Food and Drug Administration (FDA) consumer inquiry line toll-free at 1‑888‑INFO‑FDA (1‑888‑463‑6332) or visit
