Hi,
There are many medical conditions that can cause hypersalivation; therefore, it is a common symptom. Causes of saliva overproduction include excessive starch intake,
gastroesophageal reflux disease (GERD), pancreatitis, liver disease,
serotonin syndrome, oral ulcers, oral infections, pellagra or
vitamin B3 deficiency, rabies, cerebral palsy, stroke,
motor neuron disease etc. Drinking plenty of water can reduce saliva production. Tooth brushing and rinsing with mouthwash can also temporarily dry out the mouth.
Anticholinergic medications like Glycopyrrolate and Scopolamine are effective in reducing the overproduction of salivation, but their use may be limited by side effects.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Zubayer Alam, General And Family Physician,
