Understanding Sulfite Allergy
A Word From Verywell
The nuances of a sulfa allergy can be tricky to tease out, even for some healthcare providers. That's why it's important to tell your doctor about any prior reaction you may have had to a sulfa medication (or any other drug for that matter). Sharing that information will make it easier for your doctor to prescribe a substitute that is less likely to cause an adverse reaction. Was this page helpful? Thanks for your feedback!
