Is Your Medicine Giving You a Rash?

Some people have an allergic reaction to medicine and may break out in a rash. If this happens to you, call your doctor. They may tell you to stop taking the medicine and prescribe another. They'll also be able to find out if there's another cause to your skin problem, like a medical condition.
