From the Guidelines
Hypersalivation requires a comprehensive workup to identify the underlying cause.
Initial Evaluation
The initial workup should include a thorough medical history and physical examination to identify any underlying causes such as neurological disorders, gastrointestinal issues, or medication side effects [ 1 ].
Recommendations include:
- Checking for any signs of infection, inflammation, or obstruction in the oral cavity and salivary glands
- Reviewing current medications for potential side effects that may contribute to hypersalivation
- Considering laboratory tests such as complete blood count, electrolyte panel, and liver function tests to rule out systemic causes
- In some cases, imaging studies like ultrasound or CT scans of the salivary glands may be necessary [ 1 ]
- Referral to a specialist such as an otolaryngologist or a neurologist may be required for further evaluation and management
Diagnostic Approach
Baseline evaluation of salivary gland function is recommended before starting treatment for oral dryness, which may be relevant in some cases of hypersalivation [ 1 ]. The therapeutic approach to oral dryness should be driven by the baseline measurement of salivary glandular function.
Treatment
Medications that may be considered for symptomatic relief include:
- Anticholinergics like glycopyrrolate (1-2 mg orally three times a day) or scopolamine (1.5 mg transdermal patch every 3 days)
- Muscarinic receptor antagonists like sublingual atropine (0.5-1 mg as needed)
- In patients with neuromuscular weakness and sialorrhea who have an inadequate response or are intolerant of the side effects of anticholinergic therapy, botulinum toxin therapy to salivary glands may be considered [ 1 ]
It's essential to tailor the treatment approach to the individual's specific needs and underlying cause of hypersalivation.

From the Research
Hypersalivation Workup
There are no research papers to assist in answering this question. The provided studies do not mention hypersalivation or its workup.
Relevant Information
- The studies provided discuss various medical conditions and their workups, including eosinophilia 2, pediatric esophageal foreign bodies and caustic ingestions 3, neurocritical care examination and workup 4, headache disorders 5, and cutaneous flushing 6.
- These studies highlight the importance of a thorough history, physical examination, and diagnostic tests in determining the underlying cause of a patient's symptoms.
- However, none of the studies specifically address hypersalivation or its workup.
Diagnostic Approach
- A diagnostic approach typically involves a combination of:
- Detailed history and physical examination
- Laboratory tests and analyses
- Imaging studies
- Specialist input (e.g., neurology, gastroenterology)
- The specific workup for a patient's symptoms depends on the suspected underlying cause, as discussed in the provided studies 2, 3, 4, 5, 6.
