Metformin, which helps control blood sugar levels and is often prescribed for people with type 2 diabetes, has been subject to recalls in the past. However, the FDA advises patients to continue taking their medication and contact their physician for advice regarding an alternative treatment. It may be dangerous to stop taking metformin without first speaking to a health care professional.
As of Jan. 3, Viona has not received any reports of illness or death related to this recall. NDMA is an environmental contaminant found in water and food, such as meat, dairy products and vegetables. The affected tablets were manufactured in India by Cadila Healthcare Limited and distributed in the U.S. by Viona.
