Hi Martin.
There isn't a pharmacy in Arillas, there was one but it closed down. The previous posts mentioning the pharmacy are from a couple of years ago. So, yes, Avliotes still has the nearest pharmacy. I had to go there in 2012 when I got a tooth abscess and needed antibiotics, the pharmacist at the time was smoking behind the counter .... I personally didn't mind, but can you imagine that happening here?!
