Best Approach for Tapering Duloxetine 120mg Daily
The best way to taper off duloxetine 120mg daily is to reduce the dose gradually over at least 2-4 weeks, with initial reduction to 60mg daily for 1-2 weeks, followed by 30mg daily for 1-2 weeks before discontinuation. 1
Understanding Duloxetine Discontinuation
Duloxetine is a selective serotonin and norepinephrine reuptake inhibitor (SSNRI) that requires careful tapering to minimize withdrawal symptoms. Abrupt discontinuation commonly leads to:
- Dizziness (most common at 12.4%)
- Nausea (5.9%)
- Headache (5.3%)
- Paresthesia (2.9%)
- Vomiting (2.4%)
- Irritability (2.4%)
- Nightmares (2.0%) 2
Recommended Tapering Protocol
Step 1: Initial Dose Reduction
- Reduce from 120mg daily to 60mg daily
- Maintain this dose for 1-2 weeks
- Monitor for withdrawal symptoms
Step 2: Secondary Reduction
- Reduce from 60mg daily to 30mg daily
- Maintain for 1-2 weeks
- Continue monitoring for withdrawal symptoms
Step 3: Final Discontinuation
- After 1-2 weeks at 30mg, discontinue completely
- Consider extending the taper if withdrawal symptoms are significant
Special Considerations
For More Sensitive Patients
For patients who experience significant withdrawal symptoms during the standard taper:
- Consider a more gradual taper with smaller decrements (10% reductions)
- Extend the taper period to several months if needed 1, 3
- For patients on duloxetine longer than 3 weeks, a minimum 2-4 week taper is essential 1
Adjunctive Medications for Withdrawal Symptoms
If withdrawal symptoms are problematic, consider:
- α2-Adrenergic agonists like clonidine to suppress withdrawal symptoms 1
- Tizanidine as an alternative with less hypotensive effects 1
- For sleep disturbances: trazodone or mirtazapine short-term 1
- For gastrointestinal symptoms: loperamide 1
Monitoring During Taper
- Assess for withdrawal symptoms at each dose reduction
- Common withdrawal symptoms include dizziness, nausea, headache, and paresthesia 2
- Most withdrawal symptoms resolve within 7 days of onset 2
- Monitor for return of original symptoms that duloxetine was treating
Important Cautions
- Never discontinue duloxetine abruptly due to risk of significant withdrawal symptoms 1
- Higher doses (120mg) are associated with more withdrawal symptoms than lower doses 2
- Patients should be informed that duloxetine should only be discontinued after consultation with their provider 1
- If severe withdrawal symptoms occur, consider returning to the previous dose and tapering more slowly
Follow-up Care
- Schedule follow-up within 1-2 weeks of complete discontinuation
- Assess for persistent withdrawal symptoms or recurrence of original condition
- Consider non-pharmacological approaches such as exercise, cognitive behavioral therapy, or mindfulness techniques to help manage symptoms during and after tapering 1
This tapering protocol balances the need to minimize withdrawal symptoms while achieving complete discontinuation in a reasonable timeframe, prioritizing patient safety and comfort throughout the process.
