Pfizer is forced to recall drug used to treat hypertension after pills were found to be contaminated with cancer-causing compounds

Pharmaceutical giant Pfizer is recalling five batches of its hypertension drug Accupril after it was found to contain chemicals that can cause cancer. 

The recall comes after research found that batches of the drug contained increased levels of a cancer-causing agent, nitrosamine. It was announced on March 22 and involves five batches of pills, each containing 90 bottles.

Pfizer says those bottles may have been split into smaller prescriptions, and has urged any doctor or pharmacist who dealt with the shipments in question to contact them immediately.  

The drugs were distributed in the United States and Puerto Rico between December 2019 and April 2022, a Pfizer news release said.
