Antidepressants With the Least Sexual Side Effects: A Practical Guide

Sexual side effects are one of the most common reasons people stop antidepressants, and we still do a surprisingly poor job talking about them. Patients often do not bring it up unless I ask. Sometimes they assume it is the depression, their hormones, their relationship, or just something they have to live with if the medication is helping.

It isn’t always. And there are more options than people realize.

Why does it happen?

Sexual response is actually pretty complicated. Desire, physical arousal, erection or lubrication, and orgasm do not all run through exactly the same pathway. Dopamine and norepinephrine tend to support sexual interest and arousal, while serotonin can inhibit several parts of the sexual response.

That becomes relevant with SSRIs and SNRIs because they increase serotonin. That is part of what makes them so useful for depression and anxiety, but the same serotonin effect can dampen dopamine signaling and interfere with the nerve and blood-flow pathways involved in sexual function.

This is why the side effect does not look the same for everyone. One person loses interest in sex. Another still wants sex but has trouble becoming physically aroused. Some women notice less genital sensation or difficulty reaching orgasm. Some men can get an erection but have trouble maintaining it, while others develop delayed ejaculation or cannot orgasm at all.

Erectile dysfunction in particular is not simply about “not being in the mood.” Erections depend partly on nitric oxide and healthy blood flow to penile tissue, and increased serotonin can interfere with those pathways as well as the spinal reflexes involved in erection and ejaculation.

So when someone tells me, “Mentally I want to have sex, but my body isn’t cooperating,” that actually makes pharmacologic sense.

Not all antidepressants are the same

This is the part that surprises people. Because the culprit is mostly serotonin, the antidepressants that work through other systems, or that touch serotonin in a more targeted way, tend to be far easier on your sex life. Here are the main ones I find myself talking about.

Bupropion (Wellbutrin)

Wellbutrin is probably the medication I talk about most when sexual side effects are a major concern. Unlike SSRIs and SNRIs, it works primarily through dopamine and norepinephrine rather than serotonin, so sexual side effects are much less common. Some people actually notice an improvement in libido.

It is also commonly added to an SSRI or SNRI when that medication is working well but causing sexual problems. In other words, you do not necessarily have to give up an antidepressant that is helping just because this side effect shows up.

The trade-off is that Wellbutrin can be activating. That can mean more energy and motivation, but for some people it can also mean increased anxiety or trouble sleeping, particularly at first. It is also generally avoided in people with seizure disorders or certain eating disorders.

Exxua (gepirone ER)

Exxua is one of the newer antidepressants, and it caught my attention partly because of what it doesn’t seem to do. Sexual side effects and weight gain, two of the biggest complaints I hear with traditional antidepressants, appear to be relatively uncommon.

It works differently from an SSRI. Exxua is a selective 5-HT1A receptor agonist, meaning it targets a specific serotonin receptor rather than broadly increasing serotonin throughout the brain. That more targeted mechanism may help explain why sexual functioning was largely preserved in clinical trials.

I am still somewhat cautious with it because it is new. FDA approval is one thing; years of real-world experience are another. Dizziness, nausea, and sleep changes can occur, particularly when starting it. Exxua can also prolong the QT interval, so cardiac history, other medications, and potential interactions need to be considered.

Still, for someone who needs an antidepressant and is particularly concerned about sexual side effects or weight gain, it is an option I think is worth knowing about.

Trintellix (vortioxetine)

Trintellix has been around longer, so we have more experience with it. It still works through serotonin, but in a more complex and selective way than a traditional SSRI, and sexual side effects tend to be less common.

What I find particularly useful is that Trintellix has actually been studied in people who were doing well on an SSRI but developed sexual side effects. When they were switched to vortioxetine, sexual functioning improved while the antidepressant benefit was maintained. That is a situation I see all the time: the medication is helping, but the sexual side effects are not acceptable.

It is not completely free of sexual side effects, especially at higher doses, but overall it tends to be easier in this area than many traditional SSRIs. The most common complaint I hear with Trintellix is nausea, particularly when first starting it.

Viibryd (vilazodone)

Vilazodone works like an SSRI but adds a targeted action at that same mood-related serotonin receptor Exxua uses, which may soften the sexual side effects somewhat. I want to be careful here, though, because the evidence is more mixed than the marketing once suggested. Some of the early impression that it caused almost no sexual side effects turned out to be a quirk of how the studies were designed. So the fair way to put it is that vilazodone is possibly gentler than a standard SSRI, but the case for it is weaker than it is for bupropion or vortioxetine. Its most common side effect is diarrhea, which often settles within a couple of weeks, and it needs to be taken with food to work properly.

Mirtazapine (Remeron)

Mirtazapine takes a different route again. Where SSRIs turn up serotonin at the receptors that cause sexual problems, mirtazapine actually blocks those particular receptors, so sexual dysfunction tends to be uncommon. The trade-off is real, though, and it is the reason mirtazapine is not for everyone: it commonly causes drowsiness and increased appetite and weight gain. For a person whose depression comes with terrible sleep and little appetite, those effects can actually be useful. For someone already struggling with weight or daytime fatigue, they may make it a poor fit. This is a good example of how the right antidepressant depends on the whole picture, not just this one issue.

Auvelity (dextromethorphan-bupropion)

Auvelity is interesting because it does not work like a typical SSRI at all. Dextromethorphan acts partly through the glutamate/NMDA system, while its other ingredient is bupropion, which we already know tends to be easier on sexual function. Sexual side effects appear to be relatively uncommon with Auvelity as well. If you want the fuller story on how it works and who it fits, I wrote a whole piece on it: Auvelity: the oral antidepressant that works more like ketamine.

If you are already having sexual side effects

Maybe your antidepressant is actually working. You feel less depressed or anxious, but your sex life has changed. This is where people sometimes assume they have two choices: live with the side effect or stop the medication. Usually, there are more options than that.

What I recommend depends partly on what has changed. Low desire is different from difficulty becoming physically aroused, and both are different from delayed or absent orgasm. For men, the issue may specifically be difficulty getting or maintaining an erection.

Sometimes lowering the antidepressant dose is enough to improve sexual function without losing the benefit. Sometimes adding bupropion (Wellbutrin) helps. In other cases, switching to an antidepressant with fewer sexual side effects makes more sense. For men with erectile dysfunction, medications such as sildenafil (Viagra) or tadalafil (Cialis) can sometimes help, particularly when the antidepressant is otherwise working well.

What I would not recommend is simply stopping the antidepressant on your own. Depending on the medication, stopping abruptly can cause significant discontinuation symptoms and increase the risk that depression or anxiety returns. The goal is not to give up a treatment that is helping. It is to figure out whether we can keep the benefit without accepting a side effect that matters to you.

How to bring it up with your prescriber

I know this can feel awkward to raise. You do not need the perfect words. Something as simple as, "The medication is helping my mood, but it is affecting me sexually, and that matters to me," is more than enough to start.

If you can, be a little specific, because different problems point to different solutions. Low desire, difficulty with arousal, and trouble reaching orgasm are not all fixed the same way. And if your clinician brushes it off or makes you feel small for asking, that tells you something too. A good prescriber will not be surprised or embarrassed, because we hear this all the time, even if patients rarely bring it up first.

What about sexual side effects that persist after stopping?

If you research this topic online, you will probably come across post-SSRI sexual dysfunction, or PSSD. This refers to sexual symptoms that persist after an SSRI has been discontinued. European regulators have acknowledged that this can occur, but we still do not know how common it is or why it happens to some people. I would not use this to frighten someone away from an antidepressant they need, but I also don’t think it should be ignored. It is worth knowing about and discussing with your prescriber if it is a concern.

My take

Sexual side effects matter. They affect intimacy, relationships, self-esteem, and whether people actually stay on their medication. I don’t consider that a minor side effect.

I also don’t think someone who is finally feeling better on an antidepressant should assume the only choices are to tolerate it or give up a medication that works. Sometimes the solution is a dose adjustment. Sometimes we add something. Sometimes changing medications makes more sense.

If your antidepressant is helping your depression but hurting your sex life, tell your prescriber. We can’t address a side effect we don’t know you’re having.
