Medical and Pharmacy Editor:
SIDE EFFECTS: Common side effects of penicillin V include:
Patients with a history of allergic reactions to other penicillins should not receive penicillin V. Persons who are allergic to the cephalosporin class of antibiotics, which are related to the penicillins, for example, cefaclor (Ceclor), cephalexin (Keflex), and cefprozil (Cefzil), may or may not be allergic to penicillins.
Serious but rare reactions include:
Penicillins can alter the normal bacteria in the colon and encourage overgrowth of some bacteria such as Clostridium difficile which causes inflammation of the colon (pseudomembranous colitis). Patients who develop signs of pseudomembranous colitis after starting penicillin (diarrhea, fever, abdominal pain, and possibly shock) should contact their doctor immediately.
