Amoxicillin
"I started taking Amoxicillin on Friday evening for bronchitis and saw major improvements by that Sunday. I noticed that following Wednesday I started having some diarrhea, and now today, I am having major diarrhea that caused me to miss work. I am taking the Amoxicillin twice a day for 10 days. I will complete the regimen but hoping the diarrhea goes away soon."
