Pharmacies in Europe: If you do get something like a bladder infection, go to a pharmacy and ask them if you can get antibiotics or whatever medication you need. I was able to get antibiotics without seeing a doctor. If one pharmacy won’t give it to you, try the next one around the corner. If you have allergies or another medical condition, try to bring your own if you think you will need them because things like your favorite cold or allergy medication may be hard to find the brand you like.
