Pharmacists can help you understand how to use medicines safely and what to do when instructions, side effects or interactions are unclear. Preparing a short list of questions can make the conversation more useful, especially when you take several medicines or have recently left hospital.
This guide helps you prepare questions. It does not tell you to change or stop a prescribed medicine. Sudden changes can be unsafe for some medicines, so speak to an appropriate healthcare professional first.
1. What is this medicine for?
Knowing the intended purpose helps you understand why the medicine is part of your treatment and what it is expected to do. If you have several medicines, ask about them one at a time rather than assuming two similar-looking tablets have the same purpose.
2. How and when should I take it?
Ask whether timing matters, whether the medicine should be taken with food, and whether tablets should be swallowed whole. Some medicines have important instructions that differ from the general rule on the label.
3. What should I do if I miss a dose?
Do not automatically double the next dose. The correct action depends on the medicine and timing. A pharmacist can explain the instructions for the specific medicine you use.
4. What side effects should I know about?
Ask which side effects are common, which may improve with time and which require medical advice. It is also useful to ask what symptoms should be treated as urgent or emergency problems.
5. Could this interact with my other medicines?
Bring a complete medicine list, including over-the-counter products, vitamins, herbal products and supplements. This gives the pharmacist more information when checking for possible interactions.
Use our medicine-list guide to prepare a current record.
6. Can I take over-the-counter medicines with it?
Cold remedies, painkillers, antihistamines and other products may duplicate ingredients or interact with prescription medicines. Ask before combining products when you are unsure.
7. Are there foods, drinks or supplements I should avoid?
Some medicines can interact with alcohol, particular foods or supplements. Do not assume that a product is harmless because it is sold as “natural.” Ask about the specific combinations you use.
8. How long should I take this medicine?
Some medicines are short courses; others are intended for long-term use. If the expected duration is unclear, ask. Do not stop a long-term medicine simply because you feel better unless a healthcare professional has advised that plan.
9. How will I know whether it is working?
The answer may involve symptom improvement, a measurement, a blood test or a later review. Mersey Care NHS Foundation Trust includes this among useful questions to ask about medicines and also recommends asking about benefits, risks and alternatives.
See its current guidance on understanding your medicines.
10. Do I need a medicine review?
If you take several medicines, have recently left hospital, have new side effects or are unsure whether all current medicines are still needed, ask whether a review is appropriate. The type of review available may depend on your GP practice, pharmacy and local NHS arrangements.
11. Has anything changed since my hospital stay?
Hospital admission and discharge are common points where medicines change. If the new list does not match your previous prescriptions, ask which version is current rather than trying to reconcile it yourself.
Family carers can also use our guide to organising medicines and health information.
12. What if I have trouble swallowing, opening packaging or remembering doses?
Tell the pharmacist about practical difficulties. They may be able to explain suitable formulations, packaging options, reminder strategies or when another professional needs to assess the problem. Do not crush tablets or open capsules without checking because this can change how some medicines work.
13. Is this available through Pharmacy First?
In England, Pharmacy First allows participating community pharmacies to assess and manage seven defined common conditions through NHS clinical pathways. It is not a general substitute for GP or emergency care, but the pharmacist can tell you whether the service is relevant to your situation.
For the current scope, see NHS England’s Pharmacy First specification.
14. Who should I contact if I have a problem later?
Ask whether the pharmacy, GP practice, NHS 111 or another service is the appropriate next contact if the medicine causes a problem or your symptoms worsen.
