Type of Infections Cephalosporins Are Used Against
Cephalosporins are used to treat a wide range of infections, including pneumonia, strep throat, various staph infections including those of the skin, tonsillitis, bronchitis and gonorrhea. Cephalosporin is also commonly used prophylactically with surgical procedures, as a preventative measure to avoid infection.
Antimicrobial Spectrum of Cephalosporins

The generations to follow have successively increased activity against Gram-negative bacteria, with the trade-off of then being less effective against Gram-positive microbes.
Side Effects of Cephalosporins
Cephalosporins are similar to penicillin in action and side effects, and are often used in patients with and allergy to penicillin. The most common side effects of cephalosporin are mild diarrhea, headache, sore mouth or tongue, vaginal itching and discharge, white patches in the mouth and/or tongue. These vaginal and oral side effects are due to an increase in yeast population when competing bacteria are removed.
