Dry mouth or xerostomia is the sensation of dryness or parched skin on the tongue and roof of the mouth. The condition is usually caused by a lack of action from the salivary glands, which may be responding to a variety of stimuli. Apart from the general discomfort of a dry mouth, a lack of saliva is not good for overall health. Saliva helps in the digestive process and the prevention of bacterial and fungal growth in the mouth.
Many medications can contribute to dry mouth. Among the most likely drugs to cause the condition are muscle relaxants, sedatives, and antihistamines. Prescriptions that treat nerve pain, high blood pressure, and depression can also result in dry mouth. Even drugs for treating neurological diseases can have this effect. In addition to increasing fluids, it is important to report this side effect to a doctor.
