More than 500 medications can contribute to oral dryness, including antihistamines (for allergy or asthma), antihypertensive medications (for blood pressure), decongestants, pain medications, diuretics and antidepressants. In its most severe form, dry mouth can lead to extensive tooth decay, mouth sores and oral infections, particularly among the elderly.

Nearly half of all Americans regularly take at least one prescription medication daily, including many that produce dry mouth, and more than 90 percent of adults over age 65 do the same. Because older adults frequently use one or more of these medications, they are considered at significantly higher risk of experiencing dry mouth.

The American Dental Association (ADA), Academy of General Dentistry (AGD), American Academy of Periodontology (AAP) and the American Pharmacists Association (APhA) are collaborating to expand awareness of the impact of medications on dry mouth, a condition known to health professionals as xerostomia.

With regular saliva production, your teeth are constantly bathed in a mineral-rich solution that helps keep your teeth strong and resistant to decay. While saliva is essential for maintaining oral health and quality of life, at least 25 million Americans have inadequate salivary flow or composition, and lack the cleansing and protective functions provided by this important fluid.
Dry mouth is a potential side effect of numerous medications (prescribed and over-the-counter). Among them are antihistamines, decongestants, painkillers, high blood pressure medications, muscle relaxants, drugs for urinary incontinence, Parkinson's disease medications, antidepressants and many others.
