Trazodone Taper from 150 mg to 100 mg Daily
Reduce trazodone by 25 mg every 1-2 weeks (150 mg → 125 mg → 100 mg), taking the medication shortly after a meal or light snack, with the option to administer the full dose at bedtime to minimize daytime sedation. 1
Tapering Approach
The FDA-approved prescribing information for trazodone explicitly recommends gradual dose reduction rather than abrupt cessation to minimize discontinuation syndrome 1. While specific taper rates for trazodone are not established in the literature, the general principle of slow, gradual reduction applies.
Recommended Taper Schedule
- Week 1-2: Reduce from 150 mg to 125 mg daily
- Week 3-4: Reduce from 125 mg to 100 mg daily
This represents approximately a 17% reduction every 1-2 weeks, which is more conservative than the 25% reduction commonly used for benzodiazepines 2, 3. The slower approach is justified given that:
- Trazodone discontinuation can cause withdrawal symptoms including nausea, sweating, dysphoric mood, irritability, agitation, dizziness, sensory disturbances, tremor, anxiety, confusion, headache, and insomnia 1
- The medication has a relatively short half-life (3-9 hours) 4, which may increase withdrawal risk with faster tapers
Practical Administration Details
Dosing mechanics: Trazodone 150 mg tablets are scored and can be broken 1:
- For 125 mg: Use one full 150 mg tablet broken to remove 25 mg (approximately one-sixth)
- For 100 mg: Break the 150 mg tablet to use two-thirds of the tablet 1
Timing: Administer the dose shortly after a meal or light snack 1. Given trazodone's sedative properties, taking the entire dose at bedtime is often better tolerated and reduces daytime drowsiness 4, 5.
Monitoring for Withdrawal Symptoms
Watch for discontinuation syndrome symptoms 1:
- Mood changes (dysphoria, irritability, anxiety)
- Physical symptoms (nausea, sweating, dizziness, tremor)
- Sensory disturbances (paresthesias, electric shock sensations)
- Sleep disturbances (insomnia)
- Cognitive symptoms (confusion, difficulty concentrating)
If withdrawal symptoms occur: Pause the taper and return to the previous dose until symptoms resolve, then resume tapering at a slower rate (e.g., 10% reductions every 2-4 weeks) 2, 6.
Important Caveats
- Avoid abrupt discontinuation: This significantly increases withdrawal risk 1
- Individual variation: Some patients may require slower tapers (e.g., 10% per month) depending on duration of use and individual sensitivity 2, 6
- Concurrent medications: If the patient is taking other CNS depressants (opioids, benzodiazepines), coordinate tapering carefully—benzodiazepines should generally be tapered before opioids due to greater withdrawal risks 2, 3
- Underlying conditions: Patients with depression, anxiety, or insomnia may experience symptom re-emergence that should not be confused with withdrawal 6
The proposed 2-4 week taper from 150 mg to 100 mg represents a balanced approach that minimizes withdrawal risk while achieving the dose reduction goal in a reasonable timeframe.
