| TL;DR Medicine shortages are now a structural challenge in the UK. If your prescription is out of stock, your first step is always to speak to your pharmacist. They can check whether a Serious Shortage Protocol (SSP) is active, which may allow them to supply an alternative without you needing a new GP appointment. If no SSP exists, they will contact your GP directly. |
Finding out your medication is out of stock is a stressful experience. For people who rely on regular prescription medicines to manage long-term conditions, a supply disruption can feel alarming. The important thing to know is that you are not alone; there is a clear process in place to help you, and your community pharmacist is the best first point of contact when this happens.
Medicine shortages in the UK have shifted over recent years from isolated incidents to what the All Party Parliamentary Group on Pharmacy described in July 2025 as a chronic, structural challenge. Supply disruptions affect everything from common antibiotics and HRT treatments to controlled drugs and GLP-1 weight loss injections. Understanding what you can do, and what your pharmacist can do on your behalf puts you in a much stronger position.
Why Is My Prescription Out of Stock? Understanding Medicine Shortages UK
Before knowing what to do, it helps to understand why shortages happen. The most common causes include:
Global supply chain disruption. Most medicines contain ingredients sourced from multiple countries. Manufacturing delays, raw material shortages, shipping disruptions, and geopolitical events can all ripple through to what appears on your pharmacy shelf.
Demand outpacing supply. When demand for a medicine rises sharply, such as during the surge in interest in GLP-1 weight loss treatments like Ozempic and Wegovy, manufacturers cannot always scale production quickly enough. This has contributed to shortages of semaglutide products across the UK and globally.
Manufacturer withdrawal from the UK market. If the NHS reimbursement price for a medicine falls below what a manufacturer can profitably supply, they may withdraw the product from the UK entirely, leaving no licensed supply available.
Quality and safety recalls. The Medicines and Healthcare Products Regulatory Agency (MHRA) may recall batches of medicines following quality or safety concerns. This can reduce available stock rapidly.
Stockpiling during shortage alerts. When patients or pharmacies hear about an impending shortage and over-order, available stock is exhausted more quickly, worsening access for those who need it most. The NHS SPS guidance on medicine shortages specifically advises against ordering more than you need.
Step-by-Step: What to Do If Your Pharmacy Cannot Get Your Medication
Step 1: Talk to your pharmacist first
Your pharmacist is your first and most important point of contact when your medication is unavailable. They have real-time access to the NHS Medicines Supply Tool, a live database of known shortage information that tells them whether a national shortage has been declared, what alternatives exist, and when resupply is expected.
Do not simply leave the pharmacy and assume there is nothing to be done. Ask the pharmacist directly: “Is there an active Serious Shortage Protocol for this medication? Are there any alternatives? Can you check other wholesalers or local pharmacies?”
Step 2: Understand what a Serious Shortage Protocol means for you
A Serious Shortage Protocol (SSP) is a legal instrument issued by the Department of Health and Social Care (DHSC) when a specific medicine is subject to a confirmed national shortage. An SSP gives your pharmacist the authority to supply you with an alternative without requiring a new prescription from your GP.
Under an SSP, the alternative might be:
- The same drug under a different brand name
- A different formulation of the same drug (for example, tablets replaced with capsules or liquid)
- A different strength, with dosing adjusted accordingly
- A limited supply quantity (for example, 28 days rather than a full 84-day supply) to distribute available stock fairly
Your consent is required for any substitution. The pharmacist will explain what is being supplied and why, and record it in their system. This is a fully NHS-sanctioned process.
You can check whether an SSP is currently active at the NHSBSA SSP page.
Step 3: Try other nearby pharmacies
If your usual pharmacy does not have your medication in stock and no SSP is available, it is worth checking other pharmacies in your area. Stock levels vary between pharmacies because they use different wholesalers who receive deliveries at different times. A medication unavailable at one pharmacy may be in stock at another on the same street.
Call ahead before travelling, as pharmacy staff can check their stock quickly over the phone.
Step 4: Ask your pharmacist to contact your GP
If no SSP is active and no alternative is in stock at any nearby pharmacy, your pharmacist can liaise directly with your GP surgery to arrange a new prescription for a clinically suitable alternative medicine. The NHS SPS patient guidance advises that GPs may issue a prescription for an alternative treatment option for patients who will run out of their usual supply before a resupply date.
You can also contact your GP surgery directly and explain the situation. Most surgeries will prioritise this kind of request, particularly for medicines that are essential to managing your condition.
Step 5: Do not stop your medication without medical advice
This is one of the most important messages in any medicine shortage. Many prescription medicines, particularly those for cardiovascular conditions, epilepsy, diabetes, mental health, and thyroid disorders, must never be stopped abruptly. Sudden discontinuation can cause serious, sometimes dangerous, health consequences.
If you are running very low and cannot access your medication through any of the routes above, call NHS 111 or speak to your pharmacist about an emergency supply. Under the NHS Urgent Supply of Repeat Medication provisions, a pharmacist may be able to issue a short-term supply of certain repeat medicines to bridge the gap while a formal prescription is obtained.
NHS Drug Shortage List 2026: How to Stay Informed
The NHS Specialist Pharmacy Service (SPS) maintains a live medicines supply tool accessible to healthcare professionals, which gives up-to-date information on known supply issues, active SSPs, recommended alternatives, and expected resupply dates.
While this tool is primarily for pharmacists and prescribers, the SPS medicines shortage leaflets contain patient-facing guidance you can access directly. The NHS also publishes National Patient Safety Alerts (NatPSAs) when a shortage poses a risk to patient safety.
For general awareness, the GOV.UK medicines supply provides a detailed overview of how the government manages supply chain disruptions.
What Not to Do During a Medicine Shortage
Do not stockpile. Ordering more medication than you need during a shortage worsens access for other patients. NHS guidance specifically asks patients to order only what they need until their next prescription.
Do not source medicines from unregulated online pharmacies. Unregulated online suppliers frequently sell counterfeit, substandard, or incorrectly labelled medicines. The MHRA has warned repeatedly about the risks of purchasing prescription medicines through unverified websites. Always buy from pharmacies registered with the General Pharmaceutical Council (GPhC).
Do not switch brands or doses without advice. Some medicines, including epilepsy drugs, certain thyroid medications, and lithium, require strict consistency in brand or formulation due to narrow therapeutic windows. Switching without clinical guidance can lead to under-treatment or toxicity. Always check with your pharmacist or GP before any change.
Do not assume the shortage applies to everyone equally. Supply disruptions are often localised or affect specific product codes rather than all strengths and forms of a medicine. Your pharmacist may be able to access a different formulation of your medicine without any clinical compromise.
A Note on Weight Loss Medicine Shortages
Patients seeking GLP-1 treatments such as Wegovy (semaglutide) or Ozempic have faced significant supply challenges since these medications became widely sought after for weight management. If you are exploring medically supervised weight loss options or are currently awaiting access to these treatments, Batley Pharmacy can advise on the current availability of licenced weight loss treatments and eligibility criteria.
When to Seek Emergency Help
If you run out of a critical medication such as insulin, anti-epileptics, or cardiac medicines and cannot access an emergency supply through your pharmacist or GP:
- Call NHS 111 (available 24 hours a day, seven days a week)
- In a genuine emergency involving symptoms, call 999 or go to A&E
NHS 111 can authorise an emergency prescription for certain medicines, contact out-of-hours GP services on your behalf, and direct you to the nearest pharmacy with available stock.
