whether a rash could be caused by a drug and what to do about it
Prescribers often get questions about whether a rash could be caused by a drug and what to do about it.
An allergic "drug rash" is sudden, itchy, and looks like measles. It usually starts at the trunk and spreads to the limbs.
It's most common with beta-lactams, sulfonamides, and anticonvulsants...but can occur with any drug.
