Class I · High risk Terminated Initiated Aug 3, 2018 (8 years ago)

Levothyroxine and Liothyronine

Class I — High risk. Reasonable probability of serious harm or death.

Why it was recalled

Failed Content Uniformity Specifications: Product was manufactured using an adulterated active pharmaceutical ingredient; additionally, lack of process controls and good manufacturing practices resulted in finished product failing content uniformity specifications which can result in a product having a strength that is more or less than is labeled.

Cause type: Wrong potency / content

Sub- or super-potent product, or a failed content-uniformity / assay test. You may receive too little or too much active ingredient - a direct dosing risk. All wrong potency / content recalls.

Treat this as urgent. Class I means FDA judged there is a reasonable probability of serious harm. Find the lot number on your package; if it matches the recalled lots, do not take another dose before you have spoken to your pharmacist or prescriber - today, not next week. This recall is now terminated, which means the firm has finished removing the affected product; anything on pharmacy shelves today should be unaffected.
