My son was diagnosed on Friday with Strep A. He's fine and was given antibiotics. He hates the doctor so it was hard to hear over the screaming. I thought she said antibiotics for 10 days, but I was given a prescription for 5 days (4 times a day) when I went to the pharmacy. He has enough to last a few days and I'll check with the doctor tomorrow. Just wondering if doctors would usually offer a 5 or 10 day course?
