FAQs
What are the most common causes of dry mouth?
Most episodes start with dehydration, mouth breathing, or side‑effects from common drugs such as antihistamines, antidepressants, and blood‑pressure medicines.

Which medications are known to cause dry mouth?
Antihistamines, tricyclic antidepressants, beta‑blockers, diuretics, and opioid painkillers are frequent offenders.
How can I relieve dry mouth at night without medication?
Keep nasal passages clear, use a cool‑mist humidifier, sip water before bed, and chew sugar‑free gum or lozenges after dinner to stimulate saliva.
When should I see a doctor for dry mouth?
If the dryness lasts more than a few days, is accompanied by fever, weight loss, difficulty swallowing, or you’re on a new medication, schedule a medical visit.
