In general terms, working hours of the pharmacies in Turkey are from 9 a.m. in the morning till 7.00/7.30 p.m. in the evening (depending on the daylight saving time). They are open all weekdays and on Saturdays, but closed on Sundays. If you need medicine some time other than available, you can also find some pharmacies on duty. Their list (which also states their addresses) is usually hung over the door of any pharmacy shop. There is always a pharmacy shop on duty at nights in each neighborhood.
