Medicines like ibuprofen (Advil, Motrin) and acetaminophen (Tylenol) can help you feel better. Your healthcare provider may prescribe stronger pain relievers as well.
For rash in the mouth, rinse with salt water at least four times a day. Prescription mouthwashes, sometimes called miracle or magic mouthwash, or local anesthetics like viscous lidocaine can be used to manage pain. Oral antiseptics like chlorhexidine mouthwash can be used to help keep the mouth clean.
Contact your healthcare provider if pain becomes severe and unmanageable at home.
