Sertraline and Dry Mouth (Xerostomia): How Common Is It and How to Manage It

Sertraline can cause dry mouth, and this is a recognized side effect of selective serotonin reuptake inhibitors (SSRIs). Dry mouth is listed among the common, non‑serious adverse effects in standard patient drug information for sertraline. ^[1] Dry mouth is also noted as a typical SSRI class effect. ^[2]

How Common Is Dry Mouth with Sertraline?

• Dry mouth is a commonly reported side effect of antidepressants, including SSRIs like sertraline. ^[2]
• In consumer drug information for sertraline, dry mouth is specifically listed among frequent side effects that may be mild to moderate and often improve with time. ^[1]

While exact percentages vary by study and reporting method, SSRIs generally have lower rates of anticholinergic side effects (the kind that strongly reduce saliva) than tricyclic antidepressants. Sertraline’s overall tolerability is favorable, and individual side effects typically occur at single‑digit to low‑teens percentages in many trial programs, with dose and regimen influencing incidence. ^[3] The broader antidepressant literature treats dry mouth as a common complaint, especially in older adults and those on multiple medications. ^{[4] [5]}

Why Sertraline Can Cause Dry Mouth

SSRIs like sertraline affect serotonin signaling, which can indirectly influence saliva production and oral sensation. Even without strong anticholinergic action, changes in autonomic balance and mucosal perception can lead to a dry mouth feeling (xerostomia). ^[6] This is distinct from tricyclics, which more directly reduce salivary flow via anticholinergic effects. ^[3]

Why Managing Dry Mouth Matters

Dry mouth is more than an annoyance; it can raise the risk of cavities, gum disease, mouth sores, and oral infections because saliva protects teeth and oral tissues. ^[7] It may also impact taste, speech, denture comfort, and swallowing, which can decrease quality of life. ^[4]

Practical Self‑Care Strategies

Try these simple steps first; many people find relief with consistent daily habits:

• Sip water regularly or use ice chips to moisten the mouth. ^{[8] [7]}
• Chew sugar‑free gum or suck on sugar‑free hard candies to stimulate saliva. ^{[8] [7]}
• Avoid tobacco, alcohol, and caffeinated drinks, which can worsen dryness. ^{[8] [7]}
• Breathe through your nose rather than your mouth when possible. ^{[8] [7]}
• Brush twice daily, floss daily, and maintain regular dental visits to prevent cavities. Dry mouth increases cavity risk, so oral hygiene is essential. ^[7]

If these steps are not enough, consider:

• Over‑the‑counter saliva substitutes (artificial saliva) or mouth gels/sprays designed for dry mouth. A topical sialogogue spray containing 1% malic acid improved dry mouth symptoms and increased salivary flow in a randomized, double‑blind trial of antidepressant‑induced dry mouth. ^[9]
• Prescription options such as pilocarpine (a salivary stimulant) may help appropriate candidates; low‑dose pilocarpine increased salivary output and relieved dryness in controlled studies of salivary gland hypofunction. ^[10] Pilocarpine has supportive evidence for xerostomia due to several causes, though suitability depends on your health profile. ^[11]

When to Talk to Your Clinician

• Persistent, severe dry mouth: If dryness is significantly bothersome or not improving, discuss adjusting the sertraline dose; dose changes can influence side‑effect frequency. ^{[7] [3]}
• Dental concerns: Report increased tooth sensitivity, cavities, or mouth pain; proactive dental care helps prevent complications. ^[7]
• Medication review: A clinician or dentist can evaluate all your medicines to reduce cumulative dryness risk; dry mouth risk increases with the number of medications, especially in older adults. ^[5]
• Targeted treatments: Ask about topical sprays, saliva substitutes, and prescription sialogogues like pilocarpine when lifestyle measures aren’t enough. ^{[9] [11] [10]}

Bottom Line

Sertraline can cause dry mouth, and many people experience it to some degree, especially early on. ^{[1] [2]} The good news is that simple daily strategies often help, and there are effective targeted treatments (like topical sialogogues and, in selected cases, pilocarpine) if symptoms persist. ^{[8] [7] [9] [11] [10]} If dry mouth is significantly affecting you, talk with your clinician and your dentist to tailor a plan that protects your oral health and keeps your treatment on track. ^{[7] [4]}
