Hi, I have recently had the crud going around for lack of a better word. My roommate was pre-pneumonia, sinus infection, etc. I didn t get the sinus infection but I did go to a clinic after about a week of runny nose, coughing and heaviness in chest. I was prescribed 875 mg of amoxicillin as was my roommate.. I was to take one tab every 12 hours.. I could not and cut them in half. I took them for a week but stopped because I am aching all over mostly in my legs. could this med be causing this? Thank you for your time.
