I have a question about NHS prescription fines. I have had gestational diabetes in the past, several years ago, and am still taking metformin as the consultant said I had glucose intolerance/prediabetes and a strong family history of diabetes so should take metformin to prevent the full diabetes. I have been taking metformin for 11 years now. I have always paid for prescriptions and usually get a prescription prepayment certificate. However, in April this year they stopped sending out the cards and I didn’t realise mine expired the previous month. I got a prescription and now have been fined £108. Should I be entitled to free prescriptions anyway since I am taking metformin for prevention of full diabetes? I don’t have a certificate for exemption as I’m not sure if I qualify for one. Thank you!
