The Food and Drug Administration has recalled a commonly prescribed thyroid medication, levothyroxine.
...
The FDA said they had been functioning as "subpotent drugs," meaning they had less of an active ingredient and were ultimately less effective.

Major Pharmaceuticals packaged and distributed the recalled tablets, while Cardinal Health also distributed some of the recalled products.

Here is a list of the recalled levothyroxine medications.

You can call your pharmacist to find out if the levothyroxine you are taking is covered by the recall. In addition, you can look up your levothyroxine pill using a pill identifier to help determine the status of your levothyroxine pills. Although, contacting your pharmacy is the safest method.
