If you claim free NHS prescriptions when you are not allowed, you might have to pay a penalty charge up to £100.

If you are not sure whether you are allowed free NHS prescriptions you should pay and ask the pharmacy staff for an NHS receipt and refund form.

This is also called an FP57.

If you are waiting to find out whether you're allowed free NHS prescriptions you should also pay and get an FP57.
