Potential causes of mucositis

Some chemotherapy medications and radiation therapy can cause swelling and irritation of the lining of the mouth, esophagus, stomach, intestines, and anus. This irritation may lead to sores, also known as mucositis.

Signs and symptoms of mucositis

Your child may have mucositis if:

  • The inside of their mouth appears red, with sores that are open and painful
  • They drool or have difficulty swallowing
  • They do not want to eat or drink

Treating mucositis

Unfortunately, there is no medicine available to make mouth sores go away. Your child’s healthcare team may prescribe a special mouthwash as part of their oral routine, along with pain medication to help with any pain your child may have.
