Clonazepam
Benzodiazepine
Brand names: Klonopin
Oral health effects
Xerostomia (dry mouth)
Reduced salivary flow raising caries, candidiasis, and mucosal discomfort risk.
Clinical management: Hydration, sugar-free gum/xylitol, salivary substitutes, high-fluoride products; reinforce caries prevention.
Burning mouth symptom management (therapeutic)
Topical/low-dose clonazepam is sometimes used to treat burning mouth syndrome.
Clinical management: Context-dependent; note this is a therapeutic use rather than a side effect.
Excess saliva (hypersalivation)
The label warns that clonazepam may increase salivation, which matters for patients who have difficulty handling secretions.
Clinical management: Use high-volume suction and keep the patient semi-upright if salivation is increased; take extra care with sedated or neurologically impaired patients at risk of aspiration.
