The recall involves approximately 34,845 bottles distributed nationwide within the United States and Puerto Rico. Some tablets in the affected lots are superpotent while others are subpotent, meaning the drug strength does not meet specification.

Levothyroxine is a prescription medication used for thyroid hormone replacement therapy. Potency failures could result in ineffective treatment or unintended dosing effects.
