If you get a rash after starting a new prescription medicine, call your doctor. You may want to take photos of the rash with a digital camera or cellphone and send it to your doctor. The rash may be a result of a medical problem -- not the drug you're taking. Or your doctor may tell you to stop taking the drug and prescribe a different one. If you get a rash from a non-prescription medicine, stop taking it immediately. Call your doctor if you need suggestions for a different medicine.
