202001 MHRA Levothyroxine 100mg/5ml


Wockhardt UK Ltd is recalling specific batches of the Levothyroxine 100micrograms/5ml oral solution 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 is considered to be more potent than levothyroxine. The potency difference will result in different pharmacodynamic effects for patients.


Full details of the drug alert are included in the attached PDF file. Please forward to listed recipients. This information is also published on the MHRA website https://www.gov.uk/drug-device-alerts.
