Impetigo, a bacterial infection of the skin that can occur in both children and adults, can cause blisters. Chickenpox, an infection caused by a virus, produces itchy spots, and often blisters on the skin. The same virus that causes chickenpox also causes shingles, or herpes zoster. The virus reappears in some people later in life and produces a skin rash with fluid vesicles that can rupture.
Rocephin is part of a class of drugs called cephalosporins. It prevents bacteria's ability to make and maintain their cell wall. Without a cell wall, bacteria are vulnerable and ultimately perish.
It works by fighting bacteria in your body. Rocephin is used to treat many kinds of bacterial infections, including severe or life-threatening forms such as meningitis. Rocephin may also be used for purposes not listed in this medication guide.
