Active Pharmaceutical Ingredient: levothyroxine sodium

Brief description of the problem

Wockhardt UK Ltd is recalling specific batches of the above products from pharmacies and wholesalers as a precautionary measure due to notification of the impurity liothyronine exceeding the specification limit. Liothyronine is a degradant of Levothyroxine and can be used to treat the same conditions but with a faster onset and considered to be more potent than levothyroxine. This potency difference will result in different pharmacodynamic effects for patients.

Advice for healthcare professionals

Stop supplying the above products immediately. Quarantine all remaining stock and return it to your original supplier using your suppliers approved process.

Further Information

Liothyronine is a breakdown product that is present in Levothyroxine formulations. Liothyronine, the synthetic form of the natural thyroid hormone tri-iodothyronine, can itself be used to treat an underactive thyroid but is generally reserved to treat more severe forms of the condition. This is because liothyronine has a faster onset of action and is also more potent than levothyroxine. These differences in action mean there is a higher risk of adverse effects with increasing liothyronine content and is why this is controlled within strict limits within levothyroxine preparations.
