NDMA is a possible human carcinogen that can be found in the environment and our water, as well as meats, dairy, and vegetables. It may be more hazardous to your health to cease using the medication than to take it, so experts do not want customers to just stop using it. Patients should consult their doctors though about how to move forward. The recalled medication was distributed to pharmacies nationwide.
