Cephalexin is generally well-tolerated. Large studies report an overall 6% incidence of side effects, some of which may not be related to cephalexin (the active ingredient contained in Panixine)

Hypersensitivity

Up to 20% of patients with a penicillin allergy may be allergic to cephalexin (the active ingredient contained in Panixine)

Hypersensitivity side effects have included fever, urticaria, rash, eosinophilia, anaphylaxis, angioedema, contact dermatitis, erythema multiforme, Stevens-Johnson syndrome, toxic epidermal necrolysis, acute paronychia, and hepatitis.

Gastrointestinal

Gastrointestinal side effects have included diarrhea, nausea, vomiting, dyspepsia, abdominal cramping, anorexia, and anal pruritus. Diarrhea due to Clostridium difficile colitis has been reported with some cephalosporins.

If diarrhea occurs and it does not resolve with discontinuation of the drug and/or institution of standard antidiarrheal therapy, pseudomembranous colitis should be suspected.
