Side effects occurring on Amoxi-Clav therapy are generally mild and they rarely result in discontinuation of therapy. The following side effects are possible:
Gastrointestinal side effects

Colonization of the intestine by Candida and isolated cases of pseudomembranous colitis have been described after amoxycillin therapy. Studies of effects on the intestinal flora have reported promotion of colonization by resistant enterobacteria and a reduction in staphylococci.
