    Sulfa Allergy: What Drugs to Avoid (and What’s Usually Safe)

    Sulfa allergy is one of the most commonly reported drug allergies (often cited around ~6% of patients), and it frequently leads clinicians to avoid entire medication classes—sometimes unnecessarily. In this lecture from This is Why, Dr. Busti will break down what drugs to avoid with a sulfa allergy (and what’s usually safe) by focusing on the “why”: the chemical features that drive true sulfonamide allergy risk and what that means for real-world prescribing. You’ll learn how to: - Identify what makes a drug a “sulfonamide” - Distinguish antimicrobial vs non-antimicrobial sulfonamides - Understand the structural features linked to higher allergy risk (why Bactrim is different) - Apply practical guidance for patients with a reported sulfa allergy - Avoid unnecessary “all-or-nothing” medication exclusions while still prioritizing safety The goal = make medical education easy and clinically relevant. 👉 Access bonus materials and downloads from this episode at: https://www.thisiswhy.health/topics/topics/sulfa-allergy-drugs-to-avoid 👉 Get more with a free membership at https://www.thisiswhy.health/ - Access free downloads from our videos  - Access deep dive content from Dr. Busti - Organize content via playlists & collections - Join live Q&A - Receive member newsletters - Coupons & discounts for exam prep resources 👍 If this helped you, please like, subscribe, and share it with a classmate or colleague.
