Phenytoin Supply Disruption Alert
Drug supply issues are an interesting use-case for OpenPrescribing. Here we will talk about a recent example.
What is the problem?
Last week the Department of Health and Social Care issued a “Supply Disruption Alert” for Epanutin (phenytoin) 30mg/5ml oral suspension: Pfizer, the manufacturer, will be out of stock of this product from the week commencing 29th October (today) until early December 2018. This means people currently taking Epanutin (phenytoin) 30mg/5ml oral suspension may need to be prescribed a different product.
Why is it important?
Phenytoin is a medicine that is generally used to prevent seizures in people with epilepsy. The Medicines and Healthcare products Regulatory Agency (MHRA) classify medicines for epilepsy into three different categories and phenytoin as a Category 1 antiepileptic drug. This means doctors are advised to ensure that their patient is maintained on a specific manufacturer’s product. This is important as phenytoin has a “narrow therapeutic index” which means that a person is at risk of seizures if their product is changed without medical supervision.
The alert gives very clear instructions to doctors, patients and other healthcare professionals on how to manage this situation: advice on switching, the availability of alternative products and when to access specialist advice. The alert also advises GPs to identify all patients currently prescribed Epanutin (phenytoin) 30mg/5ml oral suspension and make early contact with the patient or parent/carer.
