Medication Allergy
What is it?
Anaphylactic reactions to medication typically occur within an hour after taking the drug but may occur several hours later. It is estimated that up to one percent of the population may be at risk for allergic reactions to medications.
According to the American Academy of Allergy, Asthma & Immunology (AAAAI), “The chances of developing an allergic reaction may be increased if the drug is given frequently, or by skin application or injection rather than by mouth. Inherited genetic tendencies of the immune system to develop allergies may also be important. Contrary to popular myth, however, a family history of reaction to a specific drug does not mean that a patient has an increased chance of reacting to the same drug.”
Symptoms:
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.
