Treatment of Sertraline-Induced Decreased Libido
For patients experiencing decreased libido from sertraline, switch to bupropion as the first-line strategy, as it has significantly lower rates of sexual dysfunction compared to sertraline while maintaining antidepressant efficacy. 1, 2
Primary Treatment Strategy: Switch Antidepressants
The most robust evidence supports switching from sertraline to an antidepressant with a more favorable sexual side effect profile:
- Bupropion has a significantly lower rate of sexual adverse events than sertraline 2
- Nefazodone was significantly less likely to result in sexual dysfunction compared to sertraline (RR 0.34,95% CI 0.15-0.6) without worsening depression 3
- Mirtazapine may also be considered as an alternative with lower sexual dysfunction rates 4
The 2016 ACP guideline explicitly notes that physicians and patients should discuss adverse event profiles before selecting medication, and that bupropion is associated with lower rates of sexual adverse events than sertraline 1.
Alternative Strategy: Augmentation
If switching is not feasible due to good depression control on sertraline, consider adding:
For Men with Erectile Dysfunction:
- Sildenafil (PDE-5 inhibitor): Meta-analysis of 113 men showed significant improvement in erectile function (WMD 19.36,95% CI 15.00-23.72) without increased dropout rates 3
- Tadalafil: Associated with greater improvement in erectile function (WMD 8.10,95% CI 4.62-11.68) 3
For General Sexual Dysfunction:
- Bupropion augmentation: Improved scores on sexual functioning questionnaires, particularly desire-frequency (WMD 0.88,95% CI 0.21-1.55) 3
- Saffron (Crocus sativus): Shows promise as an adjunctive treatment 4
Less Effective Strategies
Drug Holidays (Limited Utility):
Weekend drug holidays (discontinuing Thursday morning, restarting Sunday noon) showed improvement for sertraline users, but this approach has significant limitations 5:
- May work for some patients taking sertraline or paroxetine
- Does NOT work for fluoxetine (due to long half-life)
- Risk of depressive symptom return
- Not recommended as first-line due to inconsistent efficacy
Other Augmentation Options with Weaker Evidence:
- Cyproheptadine (4-12 mg, 1-2 hours before sexual activity): Showed transitory improvement in 5 of 7 patients but causes significant sedation 6
- Evidence for other adjunctive treatments remains insufficient 3
Important Clinical Considerations
Recognize the scope of the problem: The FDA label acknowledges that sexual dysfunction rates are likely underreported because patients and physicians are reluctant to discuss them 7. Sertraline causes decreased libido in 6% of patients (vs 1% placebo) and ejaculation failure in 14% of male patients (vs 1% placebo) 7.
Do not wait and see: Sexual dysfunction is a common reason for treatment discontinuation 7, which can compromise mental health outcomes. Address this proactively rather than risking non-adherence.
Avoid switching to other SSRIs: Paroxetine has even higher rates of sexual dysfunction than sertraline 2, and switching from one SSRI to another (like paroxetine) showed minimal improvement (89.7% still had dysfunction after 6 months) 8.
Monitor depression control: When switching medications, ensure the antidepressant effect is maintained. Studies show that switching to bupropion or nefazodone maintained depression control while improving sexual function 3, 8.
