A member asked:

I have gastritis and have to take cefdinir for a sinus infection. i have pain in the middle of my stomach. can an antibiotic cause ulcers?

A doctor has provided 1 answer

Very rare: Ulcers are caused usually by helicotbacter pylori for which the treatment IS antibiotics. It is not uncommon for antibiotics to cause abdominal discomfort and sometimes pain, particularly macorlides and tetracyclines although they can all do it. Try an antacid and bland foods to start. If symptoms persist I would see a doctor.
