Monitoring for Side Effects and Adverse Reactions

Closely watch for diarrhea. Report any significant changes in bowel habits, especially if severe or bloody. This is a common side effect, and in rare cases, it may indicate a serious condition like Clostridium difficile infection.

Pay attention to nausea and vomiting. Mild nausea is often manageable, but persistent vomiting requires medical attention. Keep your doctor informed about the frequency and severity of these symptoms.

Monitor for allergic reactions. These can range from mild skin rashes to severe reactions like anaphylaxis. Watch for hives, itching, swelling (especially of the face, lips, or tongue), and difficulty breathing. Seek immediate medical help if any of these occur.

Gastrointestinal Effects

Cephalexin can sometimes cause upset stomach. Try taking it with food to minimize this. However, if stomach pain becomes severe or persistent, contact your doctor.

Other Potential Side Effects

While less common, cephalexin can cause changes in blood cell counts or liver function. Regular blood tests can help detect these issues early.
