When your prescribed medication is unavailable, you have rights. Here's what pharmacies are obligated to do and what you can request.
Emergency Supply
Under UK law, pharmacists can provide an emergency supply of most prescription-only medicines without a prescription, provided:
- You've been prescribed the medicine before
- The pharmacist is satisfied it's needed immediately
- It's not a controlled drug (with some exceptions)
- Up to 30 days' supply can be provided (5 days for controlled drugs)
Serious Shortage Protocols
When an SSP is active, your pharmacist can supply a specified alternative without contacting your GP. You should not be charged any additional prescription charges for this.
GP Alternatives
Your GP has a duty to prescribe an appropriate alternative if your usual medication is unavailable. This should be done urgently for essential medicines.
Complaints
If you feel you've been poorly served, you can complain to:
- The pharmacy's superintendent pharmacist
- NHS England (for NHS services)
- The General Pharmaceutical Council (GPhC)
- Your local Healthwatch
