Based on PubMed | How often does sertraline cause dizziness, and are there ways to prevent or manage it?

Sertraline can cause dizziness, but the overall risk appears low, typically close to placebo in many studies. In clinical data, dizziness is listed among common side effects of sertraline. ^[1] In a network meta‑analysis of older adults, sertraline had a relative risk for dizziness of about 1.14 compared with placebo, which was the lowest among the antidepressants compared, suggesting a small increase over baseline risk. ^[2] Evidence reviews indicate selective serotonin reuptake inhibitors (SSRIs) overall are generally not strongly associated with dizziness compared with placebo, in contrast to serotonin‑norepinephrine reuptake inhibitors (SNRIs), which show higher risk. ^[3]

How often does dizziness occur with sertraline?

• Clinical listing: Dizziness is reported as a possible side effect of sertraline in official drug information for patients. ^[1]
• Comparative risk: In older adults, sertraline’s relative risk (RR) for dizziness versus placebo was about 1.14, lower than many other antidepressants (e.g., duloxetine RR ~3.18, venlafaxine RR ~2.94). ^[2]
• Class perspective: Reviews of placebo‑controlled trials suggest SSRIs, including sertraline, are generally not linked to large increases in dizziness risk compared with placebo. ^[3]

These data together suggest dizziness with sertraline is usually infrequent and close to background rates, though individual experiences vary. ^{[2] [3]}

Why can dizziness happen?

• Drug effect and sensitivity: Dizziness can arise from central nervous system side effects, mild changes in blood pressure, or individual sensitivity to serotonergic modulation. ^[1]
• Orthostatic intolerance: Some antidepressants may contribute to lightheadedness when standing (orthostatic symptoms), particularly in susceptible groups (e.g., dehydration, diuretic use, older age). ^[4]
• Stopping sertraline suddenly: Abrupt discontinuation can cause dizziness that is often worse with head movement and likely vestibular in origin; this is more common with shorter half‑life SSRIs like sertraline and paroxetine. ^[5]

Practical prevention strategies

• Rise slowly and stabilize posture: Stand up gradually from sitting or lying positions, and use support (handrails, cane) if needed to prevent sudden drops in blood pressure and lightheadedness. ^[6]
• Hydration and salt intake (as appropriate): Ensure adequate fluids; in selected cases of orthostatic hypotension under clinician guidance, salt strategies have been used to counteract symptoms. ^{[6] [7] [8]}
• Time dosing thoughtfully: If dizziness is bothersome, taking sertraline at bedtime may help, with clinician approval. ^[6]
• Avoid triggers: Limit alcohol, and use caution with caffeine and tobacco, which can exacerbate cardiovascular and neurologic symptoms. ^[6]
• Safety first: Until you know your personal response, avoid driving or operating machinery due to potential drowsiness, movement problems, or reduced alertness. ^[9]

Management if dizziness occurs

• Check orthostatic vitals: Clinicians often assess blood pressure and heart rate changes from lying to standing to identify orthostatic hypotension. ^[7]
• Adjust factors: Review fluid status, recent vomiting/diarrhea, and diuretic use, as these increase risk for low sodium and unsteadiness. ^[4]
• Titrate dose or timing: Discuss with your clinician whether temporary dose reduction, slower titration, or switching dosing time could help. ^[6]
• Monitor and report red flags: Seek medical advice for chest pain, fainting, severe confusion, or persistent unsteadiness, as these can signal more serious issues. ^[4]
• Discontinuation precautions: If stopping sertraline, taper gradually to reduce vestibular dizziness related to withdrawal. ^[5]

Special considerations

• Older adults: Comparative trial data in older adults favor sertraline in terms of a lower relative risk of dizziness versus several alternatives, but individual vulnerability still matters. ^[2]
• Medication interactions: Other drugs that lower blood pressure or affect fluid balance can increase dizziness risk; share a complete medication list with your clinician. ^{[4] [1]}
• Testing and daily function: Be cautious before driving or using machinery until you understand how sertraline affects your alertness and coordination. ^[9]

Topic	Key point
Frequency with sertraline	Dizziness is listed as a possible side effect; overall risk appears low and close to placebo in comparative analyses. [1] [2] [3]
Comparative risk (older adults)	Sertraline RR for dizziness ≈ 1.14 (lowest among compared antidepressants); duloxetine and venlafaxine higher. [2]
Triggers	Rapid position changes, dehydration, diuretics, abrupt discontinuation can contribute. [4] [5]
Prevention	Rise slowly, hydrate, consider bedtime dosing with clinician approval, avoid alcohol, use supports for balance. [6] [9]
When to seek help	Chest pain, fainting, severe confusion, persistent unsteadiness warrant prompt medical review. [4]

Bottom line

Dizziness with sertraline does occur but tends to be uncommon and near placebo levels in many studies, especially compared to some other antidepressants. ^{[2] [3]} With simple strategies slow position changes, good hydration, careful dosing, and avoiding alcohol most people can prevent or lessen dizziness, and clinicians can tailor adjustments if it persists. ^{[6] [9] [7]}
