Which Antidepressants Are Least Likely to Kill My Sex Drive?

Sexual side effects are one of the most common reasons people stop taking antidepressants. It’s natural to wonder, Can antidepressants cause low libido? The short answer is yes—many do—but not all antidepressants affect libido equally. Here, we’ll review the options backed by credible research and help you have an informed discussion with your doctor.

Why Do Antidepressants Affect Libido?

Antidepressants work by changing levels of neurotransmitters in your brain. Serotonin, in particular, is key to mood regulation but also plays a role in sexual desire and arousal. When serotonin is boosted, other pathways (like dopamine and norepinephrine) may be dampened, leading to:

• Reduced sexual desire (libido)
• Difficulty achieving or maintaining arousal
• Delayed or absent orgasm

Rates of sexual side effects vary widely. For many selective serotonin reuptake inhibitors (SSRIs), studies show between 30% and 70% of users experience some degree of sexual dysfunction.

Antidepressants with Lower Risk of Sexual Side Effects

If you’re concerned about libido, these antidepressants tend to have the lowest rates of sexual dysfunction in clinical studies:

1. Bupropion (Wellbutrin®)

• Mechanism: Norepinephrine–dopamine reuptake inhibitor (NDRI)
• Sexual Side Effects:
  • Incidence ≈ 10% or lower
  • May actually improve libido in some people
• Notes:
  • Often used as an add‐on to counteract SSRI‐induced libido loss
  • Lower risk of weight gain and sedation

2. Mirtazapine (Remeron®)

• Mechanism: Noradrenergic and specific serotonergic antidepressant (NaSSA)
• Sexual Side Effects:
  • Incidence < 10% in most trials
  • Sedation is more common than sexual dysfunction
• Notes:
  • Good option if insomnia and appetite stimulation are desired
  • Can cause weight gain

3. Vortioxetine (Trintellix®)

• Mechanism: Serotonin modulator and stimulator
• Sexual Side Effects:
  • Incidence 10–20% (versus 30–40% with escitalopram)
• Notes:
  • Improves cognitive symptoms in depression
  • Generally well tolerated, but cost can be higher

4. Vilazodone (Viibryd®)

• Mechanism: SSRI + 5-HT1A partial agonist
• Sexual Side Effects:
  • Rates around 15–20% in trials
• Notes:
  • May have faster onset for mood symptoms
  • Take with food for optimal absorption

5. Agomelatine (Valdoxan®)*

• Mechanism: Melatonin receptor agonist + 5-HT2C antagonist
• Sexual Side Effects:
  • Very low rates reported (<5%)
• Notes:
  • Not available in all countries (e.g., not FDA-approved in the U.S.)
  • Works on sleep–wake cycle, good for circadian rhythm problems

*Availability varies by region; discuss with your doctor if you’re interested.

Common Antidepressants with Higher Risk of Low Libido

Most SSRIs and SNRIs carry a higher risk of sexual side effects:

• SSRIs (e.g., fluoxetine, sertraline, paroxetine, citalopram, escitalopram)
• SNRIs (e.g., venlafaxine, duloxetine, desvenlafaxine)

Reported rates of sexual dysfunction with these medications range from 30% up to 70%, depending on dose and individual sensitivity.

Strategies to Manage Low Libido on Antidepressants

If you’re on an antidepressant that’s affecting your sex drive, consider these approaches:

• Dose adjustment
  • Sometimes lowering the dose (with your doctor’s approval) can relieve side effects.
• Drug "holiday" (not recommended for all medications)
  • Briefly skipping the drug before planned sexual activity—only under strict medical supervision to avoid mood relapse.
• Add‐on therapy
  • Adding bupropion or a small dose of a phosphodiesterase‐5 inhibitor (e.g., sildenafil) can help.
• Switch medication
  • Transition to one of the lower‐risk options listed above.
• Psychosexual therapy
  • Counseling can address anxiety, relationship issues, and coping strategies.
