Diabetes patients using Hypurin Porcine Isophane insulin cartridges have been urged to check their medication is correct by the Medicines and Healthcare products Regulatory Agency (MHRA) after a packaging error came to light.
The call comes after it was found a production line for the short-acting Hypurin Porcine Neutral Insulin 100IU/ml also had a carton of the immediate-acting Hypurin Porcine Isophane Insulin 100 IU/ml.
The result of taking the wrong medication could result in a patient experiencing insulin wearing off sooner than expected.
One carton of the faster-acting insulin was intercepted by a pharmacist before it reached the patient.
Wockhardt UK Ltd, the manufacturer of the drug, said it was unlikely any more cartons had made their way onto the production line - although supply chain, patients and pharmacists should check their cartons.
The issue related to one batch of Hypurin Porcine Neutral Insulin, with the batch number PL40147. The MHRA issued a drug alert following a precautionary recall by the manufacturer.
If a pharmacist or wholesaler comes across one of the cartons from the batch in question, they should contact Wockhardt immediately. They have also been urged to contact all patients who may have stocks of the insulin. Cartons of Hypurin Porcine Neutral Insulin 100 IU/ml with the same lot number are not included in the recall and should not be returned.
Gerald Heddell, MHRA Director of Inspection, Enforcement and Standards said: “It is important that patients continue to administer their insulin as required. Patients with any questions or concerns should contact their GP or pharmacist as soon as possible. An investigation has taken place and action has been taken to rectify the issue.”
