a strong reaction in the past, such as anaphylaxis (a severe, potentially life-threatening allergic reaction) may lose their allergy.
Is a penicillin allergy genetic?
There is no evidence of penicillin allergies being genetic. Just because a family member is allergic to penicillin or an antibiotic in the penicillin family, does not mean you should be scared to take the medication.
What are some of the symptoms of a penicillin allergy?
There are several reactions that can occur immediately or shortly after (usually within an hour) of taking the dosage. These include: hives (multiple raised pink/red areas of the skin that are intensely itchy), tongue, throat and face swelling, shortness of breath, wheezing, sensation of throat closure or choking, change in voice-quality, lightheadedness, racing of the heart, chest pain, a sense of impending doom, and/or loss of consciousness, nausea, vomiting, abdominal cramping and diarrhea.
Reactions that occur later can include a whole body rash similar to measles, which occurs five to seven days after starting the antibiotic.
What do patients who have a penicillin allergy need to know?
They should be sure that their penicillin allergy or other antibiotic allergy is accurately identified in their medical records. Please make sure the type of reaction is also documented clearly. If the allergy is severe, you should wear a medical alert bracelet that identifies your drug allergy. This information can ensure proper treatment in an emergency.
Why is it very important to identify and document penicillin allergies accurately?
Penicillin is the most commonly reported drug allergy. Patients who report penicillin allergies tend to receive more expensive and stronger antibiotics, which can lead to significant adverse effects and antibiotic resistance. By identifying patients who are not actually penicillin allergic, we can improve antibiotic prescribing methods and combat the risk of super-bugs. Penicillin allergy testing is available and may be beneficial to your future health. About 98 percent of hospitalized patients with a history of penicillin allergies have a negative result when tested. Know the facts and get tested. Talk to your doctor about penicillin allergy testing.
