Treatment depends on which parts of the body are affected and is different for each person. Common treatments include artificial tears and eye ointments that help relieve dry eyes. In some cases, surgery is performed to close the tear ducts that drain tears from the eyes.
For dry mouth, common treatments include sipping water, chewing gum or sucking on sugar-free hard candy, or using a saliva substitute. A variety of drugs are used, including aspirin and ibuprofen to relieve pain, corticosteroids to alleviate inflammation, and medicines that boost production of saliva.
