| What to check | Key points |
|---|---|
| Business hours | Can you visit within the prescription validity period? |
| Language support | Can you receive explanations in your preferred language? |
| Electronic prescriptions | If needed, does the pharmacy support them? |
| Stock | Some unusual medicines may not be stocked |
| Regular pharmacy | Using the same pharmacy helps consolidate medication history |
4. What is a medication notebook and why use it?
A medication notebookrecords the names, doses, instructions and prescribing/dispensing history of medicines you use. Showing it to doctors or pharmacists helps them share information across facilities. You can also record allergies and previous side effects.
Ask a pharmacy for a paper medication notebook. Smartphone-based electronic versions also exist. Show the same notebook at medical visits and pharmacies. If you visit several facilities, try to keep everything in one notebook or app. Tell pharmacists about over-the-counter medicines and supplements too.
