After several retailers pulled ranitidine heartburn medications from their shelves, Amneal Pharmaceuticals, LLC (AMRX) has issued a recall for several ranitidine tablets and syrups because they may contain a cancer-causing impurity.

The recall affects 150 and 300 mg ranitidine tablets and 15 mg/mL ranitidine syrups. The affected medication may have N-Nitrosodimethylamine (NDMA) in amounts that are above the levels set by the U.S. Food & Drug Administration (FDA). NDMA is a substance that could cause cancer.

The ranitidine medication was produced by Amneal and is used to treat stomach acid, including the prevention of ulcers and gastroesophageal reflux disease.

Consumers can identify the recalled medication by the NDC numbers located on the product label. The affected medication was distributed to wholesalers, distributors, retailers, and repackagers.
