A lot of Americans who go abroad don't realize that not every country has the same controls on medicines. Where I live, drug stores do not sell narcotics over the counter without a prescription, or so I hear. I never tried to buy any. But they will sell antibiotics. I've had some kind of upper respiratory thing that feels almost like cold, and I kind of felt like I had a fever half the time. I either had it for two weeks or had one, then another. So I decided to get some amoxicillin to get rid of it. But they didn't have the $.75 amoxicillin for it, and they were going to charge me 2 or 3 bucks for the fancy brand. I thought I'd ask about erythromycin. They use amoxicillin all the time here, and I figured the bug might be less likely to be resistant to erythromycin. They gave me a strip of 10 for 3 days. I figured that was too short, but decided to look it up before I went next door to buy some more. The web says 7 days for upper respiratory so I went back and bought another strip today.It does seem to be helping. I feel better, at least. If I had gone to the doctor, I probably would have spent $20 or $30 (which my employer could refund if I filled out all the online forms, which is a hassle), and I would have wasted probably an hour or an hour and a half of my time. I can look up how long to take an antibiotic. When I was here before, they'd give amoxicillin for the common cold. Now they are a bit more reserved about that.If you do go abroad to a developing country and you need antibiotics, you may just be able to buy them at the drug store. I had a throat infection by the time I got off a long flight to China for a job interview I had once. I stopped at a drug store and bought some amoxicillin before I got to the campus I was applying at. If you get a prescription, you can legally bring a supply of an antibiotic back with you into the US, too when you go back, but it expires after a while
