A medical exemption certificate (MEDEX) is valid for 5 years. Once expired, you need to speak to your GP who will apply for a new MEDEX by sending in a new FP92A application form.
We'll send you a letter reminding you that your MEDEX is about to expire one month before the expiry date if you’re under the age of 60. If you’re over the age of 60, you are already entitled to free NHS prescriptions and don’t need to apply for a new certificate.
If your MEDEX expires before your new certificate arrives, pay for your medication and ask the pharmacy for a FP57 refund receipt. Once you MEDEX arrives, if it covers the date of the payment, take your FP57 refund receipt and MEDEX to any pharmacy and they will refund you. All prescription refunds must be made within 3 months of payment.
