407: When A Penicillin Drug Allergy (Or Allergic To Other Meds) Goes Away: How To Figure This Out w/ Dr. Mariana Castells

from The Healthy Skin Show · host Jennifer Fugo, MS, CNS, Clinical Nutritionist

If you’ve got a penicillin allergy, this episode is crucial for you! That’s because you can outgrow a drug allergy like this even if you developed it as an adult. Antibiotic allergies are either misdiagnosed or fade over time. Even if you avoid taking antibiotics like the plague, having a drug allergy on your medical chart can end up limiting treatment options if you find yourself truly needing them.In this episode, my guest, Dr. Mariana Castells, breaks down how drug allergies are diagnosed, how long they take to disappear, why they can appear later in life, and how “drug delabeling” could dramatically improve your care (especially when something serious happens). Dr. Mariana Castells, M.D., Ph.D., is a world-renowned expert in allergy and immunology with over 30 years of experience. Whether you have an antibiotic allergy (or you know someone who does), this is a must-listen interview!⭐️Mentioned in This Episode:- See all the references 👉 http://www.skinterrupt.com/407 - Join me in the conversation at http://instagram.com/jenniferfugo - Stop My Rashes FREE eGuide - https://www.skinterrupt.com/stopmyrashes-pod- Fix your skin using Jennifer’s method (trusted by 900+ skin rash warriors)!
