4. Sufficient Tissue Adhesion

Because of its high tissue penetration, cephalexin is useful in the treatment of infections in the skin, bones, and respiratory system, among other body regions. Its ability to eradicate diseases from many locations is improved by this quality.

Possible Adverse Reactions with Cephalexin

1. Digestive Problems

Diarrhea, vomiting, and nausea are among the most typical gastrointestinal adverse effects of Cephalexin. Though usually not too severe, these symptoms can nevertheless be annoying. Cephalexin taken with meals may lessen gastrointestinal distress.

4. Diarrhea Associated with Clostridium difficile

Like other antibiotics, cephalexin might upset the normal bacterial balance in the stomach, which may cause Clostridium difficile to proliferate excessively (C. difficile). Severe diarrhea and colitis may result from this, which is a potentially dangerous illness that needs to be treated right away.

5. Impact on the Kidneys

Although they are uncommon, kidney problems linked to Cephalexin use have been reported; these problems are more common in patients with pre-existing kidney diseases.
