I take the same drug that is being discussed. I always fill all prescriptions (although I buy everything OTC) at the what used to be the Jewish farmacia next to the little Playero in Sosua. Alberto's IS open 24 hours (so is Caroll at Super Pola) but there was a huge scandal a couple of years ago wherein Alberto's was busted for selling placebos under real drug names and at real prices. They have also been known to sell things past the expiration date, which is something a lot of people (ex-pats and Dominicans) don't remember to check every time. And the coup de grâce was that time I had to use my AmEx card there to pay for a very expensive series of injections, and by the time I got home, I had a call from AmEx that my card had been hacked. So no: I don't use Alberto's any more.
