What is the common adverse drug reaction associated with Cefdinir?

Cefdinir, a third-generation cephalosporin antibiotic, commonly presents with diarrhea as a notable adverse drug reaction. This gastrointestinal effect may arise due to the antibiotic's impact on the gut flora, disrupting the natural balance of bacteria. When normal gut bacteria are reduced, it can lead to an overgrowth of other bacteria, potentially resulting in diarrhea.

While other adverse reactions such as rash, nausea, and headache can occur with various antibiotics, they are not as commonly reported specifically with Cefdinir as diarrhea is. The significance of recognizing diarrhea as a potential side effect is crucial for patients taking Cefdinir, as they may require guidance on how to manage this reaction and when to seek medical attention, especially if it becomes severe or persistent.
