Recent research indicates that 90 percent of patients who have a history of allergic reactions to penicillin will be able tolerate the drug. Patients who need penicillin may be able to undergo a physician-supervised desensitization procedure in an effort to change their immune system’s response to the antibiotic. If you are allergic to any antibiotic, you are more likely to react to other drugs than patients who have no medication allergies.
If you experience symptoms of an allergic reaction after taking medication, speak to your doctor. If symptoms are severe, or if they resemble those of anaphylaxis, get emergency medical help immediately.
