An Introduction to Keflex Side EffectsAs with any medicine, side effects are possible with Keflex® (cephalexin); however, not everyone who takes the drug will experience 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 Keflex. Your healthcare provider can discuss a more complete list of Keflex side effects with you.)
Common Side Effects of Keflex
Keflex has been studied extensively in clinical trials, with thousands of people worldwide having been evaluated. In these studies, side effects are always documented and compared to people not taking the medicine. This way, it is possible to see what side effects occurred, how often they occurred, and how they compared to the group taking a placebo (a "sugar pill" without any active ingredients).
Based on these studies, the most common Keflex side effects occurring in either adults or children included:
- Upset stomach (dyspepsia)
- Unexplained rash
- Yeast infection.
