In the winter they are open until 1.00 pm on Saturday but in the summer they are open all day. On the coast road into Fethiye, a little bit past Macdonalds on the opposite side of the road, there is a very nice building which was totally renovated last year and is now a polyklinik, next door is a chemist which is always open on Saturdays & Sundays.
Oh, and the chemist by the Patlangic market is always open on Saturday.
