Medication & Drug Allergies FAQs
For the majority of medications, diagnostic testing is not available. Penicillin is one of the few medications for which we have standardized diagnostic testing. However, even if there is no testing available for a medication, your allergist at Impact Medical will take a detailed history and determine if it is safe to perform a cautious graded challenge to rule in or rule out a medication allergy.
Yes, outgrowing medication allergies is possible. For example, 10% of patients per year outgrow a penicillin allergy for eight years, with 20% of patients having a persistent penicillin allergy.
There is a mold called penicillium which naturally produces penicillin. If one is allergic to the mold penicillium it does not indicate a penicillin allergy.
Typically, we do not recommend taking cephalosporin if one is allergic to penicillin. Penicillin and cephalosporins both share a common structure called a Beta Lactam ring – which increases their allergic cross-reactivity. If one is allergic to penicillin, there is a 5 – 15% likelihood they will be allergic to cephalosporin.
Yes, it is possible but unlikely to be allergic to cephalosporin if you are not allergic to penicillin.
Yes. Tylenol (acetaminophen) is not in the NSAID family.
RCM contains Iodine. This is what patients react to in RCM. Iodine is often present in shellfish. Iodine sensitivity can lead to an anaphylactoid reaction, which is a non-IGE mediated response. This is not a true allergic reaction. However, patients with an iodine sensitivity can develop symptoms that mimic an allergic reaction with exposure to RCM and shellfish. Therefore, patients who are allergic to RCM should consult with an allergist at Impact Medical before eating shellfish.
This is a very common question we come across at Impact Medical. One will require a full evaluation to determine if a rash is from a medication or from the infection itself.
There are certain components of vaccines that can be tested for. For example, the MMR vaccine contains porcine gelatin which is a known allergen. Patients can be tested for an allergy to porcine gelatin.
