What is a potential side effect of Cephalexin?

Cephalexin, a cephalosporin antibiotic, is known to cause gastrointestinal upset as a common side effect. This can manifest as symptoms such as nausea, vomiting, diarrhea, or abdominal pain. The gastrointestinal system may react to the antibiotic as it alters the normal gut flora, potentially leading to disturbances in digestion and absorption.

While other side effects like rash, headache, and sleep disturbances can occur with various medications, gastrointestinal upset is particularly prominent with Cephalexin due to its impact on the gastrointestinal tract. Therefore, recognizing gastrointestinal upset as a potential side effect is crucial for patient management and education.
