I am taking prevpac - today is my 10th day of the 14 day treatment. I don't know if its that or not - but my stomach has had sharp pains and general hurting since this morning. I'm not getting worried - thinking about appendicitis or something.
Every time I take antibiotic I get gastritis (stomach inflanmmation) and the Prepac is a strong antibiotic. Sometimes the treatment is pretty bad-- I guess it depends on your sensitivity to antibiotics.
