The Massachusetts CFIDS/ME & FM Association, a 501(c)3 founded in 1985, exists to meet the needs of patients with CFIDS (Chronic Fatigue and Immune Dysfunction Syndrome, also known as Chronic Fatigue Syndrome), ME (Myalgic Encephalomyelitis) or FM (Fibromyalgia), their families and loved ones. The Massachusetts CFIDS/ME & FM Association works to educate health-care providers and the general public regarding these severely-disabling physical illnesses. We also support patients and their families and advocate for more effective treatment and research.

Drs. Ava J. Wu (professor of orofacial sciences) and Troy E. Daniels (professor of oral medicine and pathology) at the University of California, San Francisco and contributors to The Sjögren's Book, Chapter 16 on "The Dry Mouth", report that 15% of adults in the U.S. suffer from dry mouth.

Dry mouth is a common problem for people with Myalgic Encephalomyelitis /Chronic Fatigue Syndrome (ME/CFS) and Fibromyalgia (FM), often as a side effect from medications used for symptom management.

Antidepressants (especially those in the tricyclic family), muscle relaxants, antihistamines, some pain medications, and agents for overactive bladder are some of the drugs that cause dry mouth. This group of medications have anticholinergic properties—they work by targeting certain chemicals within the nervous system and their mechanism has an increased potential for certain adverse affects, including but not limited to the regulation of salivary function.

This type of dry mouth is classified as "medication-induced" and it has become increasing more frequent, even in the general population. Patients should report this side effect to their doctors and see if other medications can be substituted.

If switching medications does not help or if patients need to use certain medications, then it is very important to add adjunct therapies, partly for comfort but also to lessen long-term effects of continued dryness.

Notice about names

The Massachusetts CFIDS/ME & FM Association would like to clarify the use of the various acronyms for Chronic Fatigue Syndrome (CFS), Chronic Fatigue & Immune Dysfunction Syndrome (CFIDS) and  Myalgic Encephalomyelitis (ME) on this site. When we generate our own articles on the illness, we will refer to it as ME/CFS, the term now generally used in the United States. When we are reporting on someone else’s report, we will use the term they use. The National Institutes of Health (NIH) are currently using ME/CFS. The Centers for Disease Control and Prevention (CDC) are calling the illness CFS.

Until there is consensus on a name for the illness, the Massachusetts CFIDS/ME & FM Association name will not change.
