Allergies and Your Diabetes Meds ( Diabetes )
Allergies to sulfa antibiotics are fairly common, but could this mean that you’re also allergic to some diabetes medications? It could. If you’re allergic to sulfonamide-type medications, including sulfa antibiotics or thiazide diuretics (water pills), you may also be allergic to the sulfonylurea family of diabetes medications, such as glyburide.
Although it’s rare for people to actually develop an allergy to sulfonylurea medications when they’re allergic to sulfa antibiotics (this is called cross reactivity), be aware of any allergy symptoms including hives, breathing problems, or a rash. If you develop any of these problems after you take your medication, you’ll probably need to switch to a different one. Talk to your doctor about your options.
