Sandoz Inc. (“Sandoz”) is initiating a voluntary recall of 13 lots of oral Orphenadrine Citrate 100 mg Extended Release (ER) Tablets to the consumer level.

The presence of a nitrosamine ethanamine  impurity, which has the potential to be above the U.S. Food and Drug Administration (FDA)’s Acceptable Daily Intake (ADI) limit of 26.5 ng/day, was detected in the lots during recent testing. These 13 lots of Orphenadrine Citrate ER Tablets were shipped to customers from August 2019 to April 2021.

Nitrosamines are substances with carcinogenic potency (substances that could cause cancer) when present above the allowable exposure limits. While the use of product belonging to the recalled lots may represent a risk to patients, to date, Sandoz has not received any reports of adverse events related to the presence of a nitrosamine impurity in the lot.

Orphenadrine Citrate ER Tablets are used as an adjunct to rest, physical therapy and other measures for the relief of discomfort associated with acute painful musculoskeletal conditions. The product is packaged in 100-count and 1000-count bottles and was distributed nationwide in the USA to wholesalers and distributors.

This recall of Orphenadrine Citrate ER Tablets is specific to the lots listed above and does not apply to any other strengths of Sandoz Orphenadrine Citrate ER Tablets nor to other lot numbers of the product. Any product returned that is not associated with this recall will be destroyed, and no credit will be issued.

Consumers who have Orphenadrine Citrate ER Tablets being recalled should stop taking the recalled product and immediately consult with their physician to obtain another prescription. Consumers should contact their physician or healthcare provider if they have experienced any problems that may be related to taking or using this drug product.
