Thyroid medication recalled in US because it may not be strong enough

Thyroid medication has been voluntarily recalled after testing indicated that the tablets may not be strong enough, according to the U.S. Food and Drug Administration.

Acella Pharmaceuticals, LLC recalled one lot of 15 milligram NP Thyroid tablets and one lot of 120 milligram NP Thyroid tablets after testing found the lots to be “sub potent,” an FDA statement reads. 

“The product may have as low as 87% of the labeled amount of levothyroxine,” the notice states.

“There is reasonable risk of serious injury in newborn infants or pregnant women with hypothyroidism including early miscarriage, fetal hyperthyroidism, and/or impairments to fetal neural and skeletal development,”  the statement continued. “In elderly patients and patients with underlying cardiac disease toxic cardiac manifestations of hyperthyroidism may occur, such as cardiac pain, palpitations or cardiac arrhythmia.”
