An Introduction to Cephalexin Side Effects
As with any medicine, side effects are possible with
cephalexin (
Keflex®,
Biocef®). However, not everyone who takes the drug will experience have problems. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor, meaning they require no treatment or are easily treated by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with cephalexin. Your healthcare provider can discuss a more complete list of cephalexin side effects with you.)
