In England, not every long-term illness qualifies for free prescriptions. The list is quite specific and has remained largely unchanged for decades, with the exception of cancer being added in 2009.
To get free prescriptions for these conditions, you must apply for a Medical Exemption Certificate (MedEx) through your GP; it is not automatic.
Qualifying Medical Conditions
You qualify for a certificate if you have any of the following:
Cancer: If you are undergoing treatment for cancer, the effects of cancer, or the effects of cancer treatment.
Diabetes Mellitus: Unless it is treated by diet alone (i.e., you must be taking medication like insulin or metformin).
Diabetes Insipidus: And other forms of hypopituitarism.
Epilepsy: If it requires continuous anticonvulsive therapy.
Thyroid Disorders: Specifically myxoedema (hypothyroidism) requiring thyroid hormone replacement.
Addison’s Disease: And other forms of hypoadrenalism where substitution therapy is essential.
Hypoparathyroidism.
Myasthenia Gravis.
Permanent Fistula: For example, a colostomy, ileostomy, laryngostomy, or caecostomy requiring continuous surgical dressing or an appliance.
Continuing Physical Disability: Specifically a disability that means you cannot go out without the help of another person.
Key Things to Know
The "All-In" Rule: Once you have a Medical Exemption Certificate, all your NHS prescriptions are free, not just the ones related to your qualifying condition.
Validity: The certificate usually lasts for 5 years. You are responsible for renewing it before it expires; if you claim a free prescription with an expired card, you could face a £100 penalty fine.
How to Apply: You must ask your GP surgery for Form FP92A. You fill out your details, and the doctor signs it to confirm your diagnosis.
Refunds: If you have to pay for a prescription while waiting for your certificate to arrive, ask the pharmacist for an FP57 refund form at the time of payment. You cannot get this form later.
What if my condition isn't on the list?
Many chronic conditions (like asthma, arthritis, or mental health conditions) are not on this list. If you find yourself paying for frequent prescriptions and don't qualify for an exemption, the 12-month Prepayment Certificate (£114.50) is usually the best way to cap your costs.
