Let's take a minute to talk about your medication. This is amoxicillin. It's a penicillin that treats infections caused by bacteria. But, it won't work on infections caused by viruses, like the common cold. People usually tolerate it well and start feeling better soon. But finish the full course, or the infection could return and become hard to treat. Some people may get an upset stomach, and taking it with meals should help. Also, diarrhea can occur, and your pharmacist can advise you how to lessen this. But, if diarrhea is severe or lasts more than 2 days, let the doctor know, even if it happens weeks from now. Also, tell your doctor or pharmacist if you notice a rash, because it could be related to this medication. For best results, don't skip doses, and try to get plenty of rest.
