Lupus: Dry mouth is related to lupus. Involment of the salivary glands, a side effect of your meds, or systemic effects of lupus may lead to the dryness, especially breathing problems, mouth breathing at night. You should have a complete evaluation to see what might help best. Treatment may be a mouth moisturizer or a humidifer at bedside. A breathing test for sleep apnea may be needed.
