Q

What is a key educational point about sulfonylureas?

a) avoid if GFR<30
b) avoid alcohol while using
c) monitor K+ while using
d) educate patient that yeast infections are common

A

Answer: b) avoid alcohol while using

Sulfonylureas can cause a disulfuram-like reaction and alcohol potentiates the hypoglycemic effect of the drug.

Note: DO not breastfeed while on these meds either!
