Starting a new medicine, taking several treatments or unsure about the instructions? A short, well-prepared conversation with your pharmacist can help prevent everyday mistakes.
MEDICINE SAFETY
Know your medicine. Clarify the instructions. Discuss changes with a healthcare professional.

When is the conversation especially important?
The World Health Organization highlights key stages for medication safety: starting, taking, adding, reviewing and stopping medicines. Discuss questions at these stages with your doctor and pharmacist. [1]
5 questions for your pharmacist
- What is this medicine for? Check its name and active ingredient.
- How and when should I take it? Ask about the dose, timing and whether food matters.
- What should I watch for? Learn about possible side effects and when to seek help. [2]
- Does it fit with my other treatments? Include nonprescription medicines, vitamins and herbal supplements. [5]
- What if I miss a dose? Advice depends on the medicine: check its patient leaflet and ask your pharmacist. Do not double a dose unless your prescriber specifically advises it. [4]
Different names do not always mean different ingredients
Two differently named products may contain the same active ingredient. Ask your pharmacist to check the ingredients before combining treatments. Include vitamins and herbal supplements in the conversation: interactions with food, drinks and other products can matter. [6]
Make the instructions clear for everyday life
You understand “twice a day”, but are unsure how to choose the times? Ask a specific question. Show the package or prescription and clarify timing, treatment duration and whether food matters. Mention any difficulty swallowing, too: your pharmacist can help clarify a suitable way to take the medicine. [7]
Do not decide on your own to split or crush a tablet or open a capsule. With some formulations, changing the medicine in this way can affect how it works. Even if a previous tablet could be split, check again for the new product. [8] [9]
One list, a clearer picture
Keep a paper or phone record of each medicine’s name, dose, instructions and purpose. Include allergies. Update the list whenever something changes and show it at your next medical or pharmacy visit. [3]
Keep to the plan when you feel better
Do not reduce a dose, substitute a medicine or stop treatment on your own. If side effects trouble you or the routine is difficult, discuss this with the professional who prescribed your treatment. [5]
A short note to prepare before visiting the pharmacy
Organise your questions under three headings: what am I taking, what is unclear, and what is difficult? For example: “How can I fit the timing around work?”, “Should this supplement be on my list?” or “What does this instruction mean?” A written note gives the conversation a practical focus and helps you remember an important question.
