Sulfa Drug Allergy

A sulfa drug allergy occurs when the immune system reacts negatively to sulfonamide medications, often used to treat bacterial infections. Symptoms can include rashes, fever, and swelling, and in severe cases, it may lead to more serious conditions like difficulty breathing or swelling of the face. People with this allergy need to avoid sulfa drugs and inform their healthcare providers about it. It’s important to note that not all antibiotics are sulfa-based, so alternatives are typically available. If someone suspects they have this allergy, they should seek medical advice for proper diagnosis and management.
