FDA Recalls Metformin and NP Thyroid

Metformin and NP Thyroid Recalled

The FDA has issued a recall of two drugs–NP Thyroid and Metformin–after testing revealed that they weren’t up to code. Read more below, and if you’re taking either medication, please be sure to contact your doctor for how to continue treatment responsibly. 

NP Thyroid Recalled

Thirteen lots of NP Thyroid, a tablet used to help treat hypothyroidism (underactive thyroid), was recalled due to being found hyper potent. Acella Pharmaceuticals, the makers of NP Thyroid, is voluntarily recalling the drugs after testing found up to 115% of the ingredient Liothyronine (T3).   

Patients with hypothyroidism who take NP Thyroid may experience symptoms such as weight loss, heat intolerance, fatigue, muscle weakness, hypertension, chest pain, rapid heart rate, or heart rhythm disturbances. And if you’re pregnant, then the possibility of having a miscarriage and impairment to the fetus increases.

If you’re taking NP Thyroid and have concerns, speak to your health care provider before you stop taking your medication. You can click here for the list of specific lot numbers of the tainted product. 

Blood Sugar Drug Contains NDMA

An extended-release version of Metformin–a drug used to control high blood pressure in patients with type 2 diabetes–contains more than the FDA’s acceptable limit of NDMA, which has been linked to liver damage.

Five companies have been asked to recall their products voluntarily. If you take Metformin ER, don’t fret: many companies, which meet FDA guidelines, will continue to manufacture the drug, and the FDA said that it would ensure these recalls don’t cause a shortage of supplies.
