If You Drool While Sleeping Often, Check for These 6 Diseases

5. Medication Side Effects – The Hidden Culprit

What It Is:
Certain medications can increase saliva production as an unintended side effect.

Common Offenders:

• Antipsychotics (e.g., clozapine)
• Medications for Alzheimer’s (e.g., cholinesterase inhibitors)
• Some anti-nausea drugs
• Seizure medications

Why It Causes Drooling:
These drugs can overstimulate the salivary glands, leading to excess saliva that’s hard to swallow — especially during sleep.

What to Do:
Review your medications with your doctor. Never stop taking prescribed meds on your own — but ask if dosage adjustments or alternatives are available.
