After a series of recalls for heartburn medications, such as Zantac, and a number of retailers pulling the product from their shelves, Aurobindo Pharma USA (AUROPHARMA.NS) has recalled 38 lots of ranitidine heartburn medication and syrups because they may contain a cancer-causing ingredient.

The recalled medication includes one lot of ranitidine tablets, 150 mg and 37 lots of ranitidine capsules, 150 and 300 mg, and ranitidine syrup, 15 mg/mL, because of the detection of N-nitrosodimethylamine (NDMA) – a cancer-causing impurity.

Ranitidine is used in the treatment of heartburn related to acid indigestion and sour stomach that is brought on by eating or drinking certain foods. The recalled medication was distributed nationwide from Sept. 28, 2018, to Sept. 19.
