Your rights
You have the right to be considered for any clinically appropriate NHS treatment. A GP refusing a prescription must have a documented clinical reason — not cost, not personal preference, and not a secret local rationing policy.
The NHS Constitution says you have the right to drugs and treatments that have been recommended by NICE for use in the NHS, if your doctor says they are clinically appropriate for you.
Valid vs invalid reasons
Valid reasons to refuse:
- Allergy or known adverse reaction to the drug.
- Drug interaction with your current medication.
- Specific clinical contraindication (e.g. certain drugs in pregnancy, with liver disease, or with particular heart conditions).
- The drug is not indicated for your condition under NHS guidelines.
Invalid reasons:
- "It's too expensive." (Not a valid basis for individual refusal.)
- "We don't prescribe that here." (Unless there is a genuine clinical policy.)
- "Try something else first." (May be valid if there is a recommended stepwise approach — ask which guideline they are following.)
- "I don't believe in that drug." (Personal belief is not a clinical reason.)
How to challenge
- Ask for the clinical reasoning. Get it in writing or in your record.
- Check the guideline. If the GP cites a guideline, read it. Many GPs have not read the full text and quote outdated summaries.
- Quote back. If the refusal contradicts the guideline, write a short note setting out the discrepancy and ask for a response.
- Second opinion. See another GP at the practice with your evidence.
- Specialist referral. Ask for referral to a specialist who can prescribe if the GP will not.
Stopping long-term medication
A GP stopping a medication you have been on for years must:
- Explain the clinical reason for stopping.
- Discuss alternatives or a tapering plan.
- Monitor for withdrawal effects or condition recurrence.
An abrupt stop without discussion — especially for antidepressants, benzodiazepines, opioids, or HRT — can be dangerous and is challengeable.
When to escalate
Escalate if:
- The refusal contradicts an NHS guideline and the GP will not engage.
- The refusal is part of a pattern affecting multiple patients (this suggests a covert rationing policy).
- A long-term medication is stopped without safe tapering or clinical justification.
- You are experiencing harm as a result of the refusal.
Start with a Stage 1 practice complaint. If unresolved, contact the ICB. If harm has occurred, consider PHSO.
Frequently asked questions
›Can a GP refuse to prescribe a medication?
Yes, but only if they have a valid clinical reason — allergy, contraindication, interaction, or the medicine not being indicated for your condition. A GP cannot refuse because of cost, because they don't like the drug, or because they are rationing prescribing.
›What if my GP refuses to continue a medication I've been on for years?
If a GP wants to stop a long-term medication, they must explain why, discuss alternatives, and provide a safe tapering plan if needed. An abrupt stop without clinical reason can be challenged as a breach of duty of care.
›Can I ask another GP to prescribe it?
Yes. You can ask for a second opinion from another GP at the same practice. If they also refuse, ask for a referral to a specialist who can review and prescribe if appropriate.
›What if the refusal is based on cost or rationing?
Individual GPs are not allowed to refuse clinically indicated prescriptions purely on cost grounds. This is called covert rationing and is against NHS prescribing rules. Ask for the refusal in writing and escalate to the practice manager.
›Can I buy the medication privately?
Some medications are available over the counter or via private prescription. However, some controlled drugs and specialist medicines cannot be obtained this way. Always discuss private purchase with a pharmacist or clinician first.
