Lannett Company, Inc. has issued a voluntary recall of Ranitidine Syrup.

The recall is due to the presence of N-Nitrosodimethylamine (NDMA) above levels accepted by the FDA.

NDMA is a "probable human carcinogen, a substance that can cause cancer, based on laboratory testing."

The recalled product is used as a short-term treatment for ulcers.

Consumers are urged to contact their physician or healthcare provider if they have experienced any problems that may be related to taking this product.
