Trazodone Dosage Guide: Starting and Adjusting
Safe Starting Doses and Quick Titration Strategies
Clinicians often begin trazodone with a conservative Rx for patients new to antidepressants or with sleep complaints. For insomnia, 25 to 50 mg at bedtime is common; for depression many start 50 to 150 mg nightly or divided, monitoring for dizziness, sedation, or interactions. Early follow up and clear Sig help catch problems and guide Titration.
| Indication | Start dose |
|---|
| Insomnia | 25 to 50 mg |
| Depression | 50 to 150 mg |
Increase dose cautiously, typically every 3 to 7 days if tolerated; slow Titration for older adults or hepatic impairment. Perform medication reconciliation, warn about additive sedation and serotonergic interactions, and schedule a brief follow up within one week after any change to assess response and side effects.
How to Adjust Doses for Insomnia Versus Depression
Clinicians often start trazodone low and observe response. For sleep a single low bedtime Rx can restore rest quickly, while depressive symptoms usually require higher sustained doses and oversight.
Sig instructions should clarify timing and advise avoiding daytime sedation. Titration is gradual, with weekly increases as tolerated while monitoring blood pressure, mood, and sleep quality.
Set realistic goals, check for drug interactions, and document changes in the Rx. Arrange follow up within weeks to reassess effectiveness, side effects, and real world functioning. Include family input and optimize sleep hygiene counseling.
Titration Schedules When and How to Increase
Begin conservatively: many clinicians start trazodone at low nightly doses and follow a clear Rx with Sig instructions, watching response for several nights before change.
Increase gradually: raise by small increments every seven to fourteen days, reassessing sleep, daytime sedation, or mood. Pause or revert if orthostasis, excessive sedation, or other adverse effects emerge and consult prescriber promptly.
Older adults need slower uptitration and routine Med Rec; choose Generics when appropriate, counsel on morning hangover risk, and schedule a Meds Check after dose increases to ensure safety and follow up.
Dosing in Older Adults and Hepatic Impairment
Elderly patients often start low and go slow; begin trazodone at 25–50 mg at bedtime with clear Sig instructions and frequent reassessment. Age-related pharmacokinetic changes increase sedation and orthostatic hypotension risk, so reduce pill burden and simplify access. Monitor for falls, cardiac conduction changes, and anticholinergic effects; perform medication reconciliation and review interactions, adjusting doses conservatively when multiple comorbidities or polypharmacy exist.
For hepatic impairment, start at roughly half the usual dose and prolong dose-adjustment intervals because clearance falls and active metabolites accumulate. Check liver function tests and observe for marked sedation, confusion, or coagulation changes; document any Rx adjustments and communicate with caregivers. When uncertainty remains, consult hepatology or a clinical pharmacist to individualize therapy and plan safe follow-up. Educate patients about orthostatic precautions, avoid driving until stable, and report excessive drowsiness or mood changes promptly for medication safety.
Managing Common Side Effects and Dose Related Risks
When starting trazodone, expect common reactions such as daytime sleepiness and dry mouth that often improve with small adjustments. Clear Sig and an Rx support safer use.
| Effect | Action |
| Drowsiness | Lower bedtime dose |
| Orthostasis | Rise slowly; monitor BP |
Adjust slowly rather than abrupt increases; titration helps balance benefit and harm. Monitor for priapism, serotonin signs, and falls, and consider cheaper or alternative agents if risks persist.
Discuss side effects at regular review, document Sig, and seek urgent attention for severe reactions. Counsel about alcohol avoidance, dose timing, and reporting any odd heartbeat or vision changes.
Interactions Contraindications and Medication Safety Checks
Before changing dosages, treat the patient’s medication story as a whole: every Rx matters. Start by listing all prescriptions, over-the-counter products, supplements, allergies, pregnancy status, and past adverse reactions; ask about alcohol and nicotine use to frame risk.
Assess for pharmacodynamic and pharmacokinetic overlap — serotonergic combinations, CYP inhibitors or inducers, QT-prolonging agents, and enzyme-related hepatic issues. Run a DUR, check renal and hepatic labs, obtain baseline ECG when indicated, and consult pharmacy when multiple interactions or high-risk comorbidities are present.
Perform medication reconciliation at each visit, record clear dosing instructions, and have patients report new symptoms immediately. Advise stopping the drug and seeking urgent care for severe rash, chest pain, syncope, or signs of serotonin excess. Encourage carrying an up-to-date medication list, delaying nonessential meds until reviewed, and involving pharmacists for verification to reduce errors, and schedule early follow-up promptly.
