Sexual side effects from antidepressants are extremely common, affecting 25% to 73% of people on SSRIs and 58% to 70% of those on SNRIs. The good news: there are several evidence-backed strategies to restore libido without giving up the mental health benefits of your medication. These range from adding a second medication to switching antidepressants, timing exercise before sex, and exploring supplements.
Why Antidepressants Lower Libido
Understanding the mechanism helps explain why certain fixes work. SSRIs and SNRIs boost serotonin in the brain, which is what helps with depression and anxiety. But that same serotonin increase suppresses dopamine, the brain chemical most closely tied to desire and pleasure. The medications also reduce nitric oxide production, which is essential for blood flow to the genitals, and they can raise prolactin levels, a hormone that directly dampens sexual interest.
This means the problem isn’t “in your head” in any vague sense. It’s a specific chemical trade-off your medication creates. And because it’s chemical, the solutions tend to be chemical or physiological too, not just psychological.
Adding Bupropion to Your Current Medication
The most well-studied add-on strategy is bupropion (Wellbutrin), which works on dopamine rather than serotonin. In one study of 47 patients with SSRI-induced sexual dysfunction, adding bupropion reversed the problem in 66% of them. Out of 75 individual sexual complaints tracked in the study, 69% improved.
Some patients in that study took bupropion on a scheduled daily basis, while others used it one to two hours before sexual activity. The as-needed approach worked for about 38% of patients, while the daily regimen was more consistently effective. This makes bupropion one of the most reliable options, and many prescribers are familiar with this combination.
Adding Buspirone
Buspirone, an anti-anxiety medication, is another add-on option. In a placebo-controlled trial, about 58% of patients who added buspirone to their SSRI reported improved sexual function over four weeks, compared to 30% on placebo. Researchers concluded the benefit came from directly counteracting the SSRI’s sexual side effects rather than from any additional antidepressant effect. The average dose used was around 48 mg per day.
Switching to a Lower-Risk Antidepressant
Not all antidepressants carry the same sexual side effect burden. If add-on medications aren’t appealing or effective, switching to a different antidepressant is worth discussing. Here’s how the numbers break down:
- Highest risk (58%–73%): SSRIs like paroxetine (70.7%), citalopram (72.7%), sertraline (62.9%), and fluoxetine (57.7%), plus the SNRI venlafaxine (67%)
- Moderate risk (22%–43%): Mirtazapine (24%), nefazodone (8%–28%), and bupropion SR (25%)
- Lowest risk: Bupropion IR (22%), and the reversible MAOI moclobemide (3.9%)
Mayo Clinic lists bupropion, mirtazapine, vilazodone (Viibryd), and vortioxetine (Trintellix) as antidepressants with the lowest rates of sexual side effects. Bupropion stands out: only about 14% of patients report sexual side effects, compared to 73% on SSRIs. The switch isn’t always straightforward since these medications work differently and may not control your specific symptoms as well, but for many people the trade-off is worth exploring.
Exercise Before Sex
This one is free and backed by real data. A study in women taking antidepressants found that 20 minutes of vigorous exercise (running on a treadmill at about 80% of maximum heart rate) significantly increased physical sexual arousal compared to no exercise. The effect was strongest when sexual activity happened within five minutes of finishing the workout and was still present at 15 minutes, though it faded after that.
Earlier research using stationary cycling showed the same pattern: moderate-to-intense cardio activates the sympathetic nervous system in a way that directly boosts genital arousal. The practical takeaway is straightforward. If you can fit in a 20-minute run, bike ride, or other vigorous cardio shortly before intimacy, it can meaningfully counteract the arousal-dampening effects of your medication. The window is narrow, so timing matters.
PDE5 Inhibitors for Men
Medications like sildenafil (Viagra) and tadalafil (Cialis) work by increasing blood flow to the genitals, which directly addresses the nitric oxide suppression caused by SSRIs. In a pilot study of 14 men with SSRI-induced sexual dysfunction, 13 experienced improvement after taking sildenafil before sexual activity. Nine of them responded at just the starting dose. The medication helped with difficulty reaching orgasm, delayed ejaculation, and erectile problems.
These medications are primarily studied in men, and evidence for women is more limited. They also don’t directly increase desire, so they work best when the main problem is physical arousal or orgasm rather than a complete absence of interest.
Maca Root Supplements
Maca root is one of the few supplements with clinical trial data specifically in people on SSRIs. A double-blind, randomized study tested maca at two doses (1.5 g/day and 3.0 g/day) in 20 people with SSRI-induced sexual dysfunction. When both dose groups were pooled together, libido scores improved significantly, dropping from 4.9 to 3.6 on a standardized scale (lower scores mean better function).
When the dose groups were analyzed separately, neither reached statistical significance on its own, likely because the study was small. The higher dose (3.0 g/day) showed a trend toward better results. Maca is generally well tolerated, but the evidence base is still limited to small studies. It’s a reasonable option to try, but expectations should be moderate.
Dose Reduction and Drug Holidays
Lowering your dose is the simplest intervention conceptually, but it carries real risk. If your psychiatric condition is well controlled, a modest reduction may ease sexual side effects while still keeping symptoms in check. This only works when supervised by your prescriber, since the line between “enough medication” and “not enough” varies from person to person.
Drug holidays, where you skip your medication for a day or two around planned sexual activity, have been specifically recommended for orgasm-related difficulties. A clinical trial found the approach was tolerable for most participants, with only mild side effects like headache (4%), agitation (4%), and impaired concentration (1.8%). However, there are real downsides. Planning sex around medication gaps can itself create stress and pressure. There’s also a risk of discontinuation symptoms, especially with shorter-acting SSRIs. Fluoxetine, which stays in your system much longer, is generally not a candidate for this approach since skipping a dose or two won’t meaningfully change its blood levels.
Putting a Plan Together
Most people benefit from combining strategies rather than relying on one. Exercise before intimacy costs nothing and can start today. Raising the topic with your prescriber opens the door to adding bupropion or buspirone, adjusting your dose, or switching medications entirely. Maca root is a low-risk supplement to try alongside other changes. For men with arousal or orgasm difficulties, PDE5 inhibitors are well supported by evidence.
The most important thing is to not quietly stop your antidepressant. Sexual side effects are the number one reason people abandon treatment on their own, and abrupt discontinuation carries withdrawal risks and the possibility of relapse. Every strategy listed here is designed to let you keep the mental health benefits of your medication while reclaiming your sex life.
