Antidepressants and Low Libido: What Can Change Sexual Desire?
16 min read
Antidepressants, SSRIs, low libido, orgasm, arousal, medication side effects, and relationship intimacy
When Your Mood Improves but Your Sex Drive Suddenly Feels Different
Antidepressants can help depression and anxiety while also changing sexual desire or sexual response for some people. You may feel emotionally more stable but notice less interest in sex, slower arousal, delayed orgasm, erection difficulties, reduced lubrication, or a feeling that sexual sensation is simply quieter than it used to be.
Some antidepressants can reduce libido or affect arousal and orgasm, particularly medicines that strongly affect serotonin such as many SSRIs. But depression and anxiety themselves can also lower sexual desire, so the medication is not always the only cause. If sexual changes began after starting or changing an antidepressant, discuss them with the prescribing clinician. Do not stop, skip, or reduce antidepressant medication on your own.
Can Antidepressants Cause Low Libido?
Yes.
Sexual side effects are recognised with several types of antidepressant.
They do not affect everyone in the same way.
Some people notice almost no sexual change.
Others notice a clear difference soon after treatment begins or after the dose changes.
The change may involve desire itself.
But it can also involve other parts of sexual response.
Antidepressant-related sexual changes are not always simply “I don't want sex.” Sometimes desire is present but arousal, sensation, erection, lubrication, or orgasm no longer responds in the same way.
This distinction matters because people often call every sexual change “low libido” even when the main difficulty is elsewhere in the sexual response cycle.
What Sexual Side Effects Can Antidepressants Cause?
Possible sexual side effects can include:
Lower sexual desire
You may think about sex less often, initiate less, or feel that sexual interest has become much quieter.
Difficulty becoming aroused
You may mentally want sexual contact but find that physical arousal develops more slowly or less strongly.
Delayed orgasm
Orgasm may take considerably longer than before or require much more stimulation.
Difficulty reaching orgasm
Some people find orgasm becomes difficult or temporarily impossible even when sexual stimulation feels pleasurable.
Erection difficulties
Some men may have difficulty getting or maintaining an erection despite still feeling attraction or desire.
Lubrication or sensation changes
Some women may notice reduced lubrication, slower arousal, or changes in genital sensation.
A person can experience one of these changes without experiencing all of them.
Why Are SSRIs Often Linked With Sexual Side Effects?
Selective serotonin reuptake inhibitors — usually called SSRIs — are widely used antidepressants.
Examples include:
- sertraline;
- fluoxetine;
- citalopram;
- escitalopram;
- paroxetine.
These medicines increase serotonin signalling.
That can be helpful for depression and anxiety, but serotonin also interacts with the systems involved in sexual motivation, arousal, orgasm, and genital response.
As a result, SSRIs are among the antidepressants more commonly associated with sexual side effects.
The type of medication, dose, individual biology, underlying mental-health condition, other medicines, physical health, and relationship context can all influence whether sexual side effects occur.
Do All Antidepressants Affect Libido Equally?
No.
The risk of sexual side effects differs between medications.
Medicines with a strong serotonergic effect tend to be more associated with sexual side effects than some other antidepressants.
That does not mean another antidepressant is automatically better for you.
Different antidepressants also differ in:
- how well they treat particular symptoms;
- sleep effects;
- weight effects;
- anxiety effects;
- other medication interactions;
- withdrawal considerations;
- other potential side effects.
A medication choice therefore has to consider the whole treatment picture, not libido alone.
An antidepressant with fewer sexual side effects for some people may not be clinically appropriate for someone else. Medication changes should be discussed with the prescriber who understands your diagnosis, treatment response, other medicines, and medical history.
Is It the Antidepressant or the Depression Causing Low Libido?
Sometimes it is difficult to separate the two.
Depression itself can reduce:
- pleasure;
- motivation;
- energy;
- self-esteem;
- interest in social connection;
- sexual desire.
Anxiety can also interfere with sexual presence and arousal.
Then treatment begins.
Mood may improve while sexual function remains low or changes in a new way.
That can make the timeline useful.
| Pattern | What may be worth discussing with the clinician |
|---|---|
| Low libido existed before medication | Depression, anxiety, stress, relationship factors, health, and medication may all be contributing. |
| Desire dropped soon after treatment began | A medication effect becomes more plausible, although other factors still matter. |
| Mood improved but orgasm became difficult | The sexual change may be more medication-related than a simple continuation of depression. |
| Sexual function changed after a dose increase | The timing is useful information for the prescriber. |
| Desire varies strongly with relationship context | Medication may be only part of the picture. |
The fact that you take an antidepressant does not mean every sexual problem is caused by the medication. The timeline and the specific type of sexual change matter.
How Antidepressants Can Affect Sexual Function in Women
Women may experience antidepressant-related sexual changes as:
- less interest in sex;
- less spontaneous desire;
- slower arousal;
- reduced lubrication;
- reduced genital sensation;
- difficulty reaching orgasm;
- orgasm taking much longer than before.
This can be particularly confusing when the relationship itself still feels good.
You may think:
I love my partner.
I still find them attractive.
Why does my body not seem interested?
The answer may be that attraction, desire, arousal, and orgasm are related but not identical processes.
Medication may alter one part of that system without changing how you feel emotionally about your partner.
For the wider female desire picture, see Low Libido in Women: Why Sexual Desire Can Change.
How Antidepressants Can Affect Sexual Function in Men
Men may experience:
- reduced sexual interest;
- difficulty getting an erection;
- difficulty maintaining an erection;
- delayed ejaculation;
- difficulty reaching orgasm;
- changes in sensation.
This can easily be mistaken for loss of attraction.
A partner may think:
If he wanted me, wouldn't he get an erection?
But erection and desire are not interchangeable.
A man may remain sexually interested while experiencing a medication-related change in erectile response or orgasm.
If erections are part of the problem, see Erectile Dysfunction and Emotional Intimacy.
For broader male desire, see Low Libido in Men: Causes and Relationship Effects.
Antidepressant Side Effects Can Become a Relationship Problem Even When the Relationship Did Not Cause Them
This is one of the most important distinctions.
The original sexual change may be medication-related.
But the couple may interpret it relationally.
The partner taking medication may think:
Something is wrong with me.
I should want sex more.
I'm letting my partner down.
The other partner may think:
They don't want me anymore.
Have they lost attraction?
Why do they never initiate?
Then a medication side effect begins creating:
- pressure;
- rejection sensitivity;
- guilt;
- sexual avoidance;
- resentment;
- less affection;
- performance anxiety.
If libido changed after starting antidepressants, do not automatically translate that into “the relationship is broken” or “attraction is gone.” Medication effects and relationship problems can overlap, but they are not the same thing.
Why Pressure Can Make Medication-Related Low Libido Harder
Suppose the medication has already made desire quieter.
Now the partner asks repeatedly:
Why don't you want me anymore?
When are we going to have sex?
How long is this going to last?
The person taking the antidepressant may now be dealing with two barriers.
First:
lower sexual response.
Second:
anxiety about disappointing their partner.
Sex can begin to feel like something they are supposed to produce despite their body responding differently.
That can make intimacy feel even less inviting.
A medication side effect can lower desire. Pressure can then turn that lower desire into avoidance.
If sex has begun feeling obligatory, see Why Sex Can Start Feeling Like an Obligation.
Can Responsive Desire Still Exist While Taking Antidepressants?
Yes.
Low spontaneous desire does not always mean there is no capacity for sexual interest.
Some people experience desire more responsively.
They may not think:
I really want sex right now.
before intimacy begins.
But wanted affection or erotic stimulation may allow genuine interest to develop.
Medication can complicate this because arousal may take longer than before.
That may mean a person needs:
- more time;
- less pressure;
- more effective stimulation;
- better conditions for concentration;
- greater freedom to stop if desire does not develop.
If someone does not want sexual contact, that boundary stands. Responsive desire only describes situations where a person is genuinely open to beginning wanted intimacy even though strong desire has not appeared yet.
See What Is Responsive Desire? and Spontaneous vs Responsive Desire: What’s the Difference?.
What Can You Do if Antidepressants Are Affecting Your Sex Drive?
The right response depends on the medication, the mental-health condition being treated, how severe the sexual effects are, and how well the treatment is otherwise working.
A clinician may discuss options such as:
Giving it time
Some side effects may become less noticeable as the body adjusts, although persistent symptoms should still be discussed.
Reviewing the dose
In some situations a prescriber may consider whether the current dose remains appropriate.
Considering another antidepressant
Some antidepressants may be less likely to cause sexual side effects for some people.
Reviewing other medication
Another prescription, hormonal medication, alcohol, or health condition may also be contributing.
Addressing a specific sexual problem
Erectile dysfunction, lubrication difficulty, pain, orgasm problems, or anxiety may sometimes need their own assessment.
Looking beyond medication
Relationship stress, sleep, depression, body image, menopause, exhaustion, and pressure may still matter even when medication contributes.
The important part is that these are clinician-guided decisions.
Do Not Stop Antidepressants Suddenly Because of Sexual Side Effects
Sexual side effects can be frustrating enough that someone wants to stop the medication immediately.
That can create another problem.
Stopping some antidepressants abruptly can cause discontinuation symptoms, and the depression or anxiety being treated may return or worsen.
Do not:
- skip doses to improve sexual function;
- halve the dose without medical advice;
- stop taking the medication suddenly;
- switch to somebody else's medication;
- add supplements or other drugs without checking interactions.
If sexual side effects are making you consider stopping treatment, tell the clinician directly. Sexual function is a legitimate treatment concern, and it is reasonable to ask whether there are safer ways to manage the problem.
What Should You Tell the Prescriber?
You do not need a perfect medical vocabulary.
Specific observations are more useful than saying only:
My sex drive is bad.
You might explain:
- when the sexual change began;
- whether it started after a new medication or dose change;
- whether desire, arousal, orgasm, erection, lubrication, or sensation changed;
- whether sexual function was already affected before treatment;
- whether masturbation is affected too;
- whether sexual problems occur every time or only sometimes;
- what other medicines or supplements you take;
- whether mood has improved on the medication;
- how much the sexual side effects are affecting your quality of life or relationship.
“Since my dose increased, I still feel desire but I cannot reach orgasm” gives the clinician much more useful information than “the medication ruined my libido.”
Do Not Assume the Antidepressant Is the Only Cause
Even when the timing points strongly toward medication, other contributors may coexist.
| Possible factor | How it may affect sexual desire or function |
|---|---|
| Depression | Can reduce pleasure, energy, motivation, self-esteem, and sexual interest. |
| Anxiety | Can interfere with relaxation, attention, arousal, erection, and orgasm. |
| Stress and exhaustion | Can make sexual interest difficult to access even when attraction remains. |
| Relationship conflict | Resentment, emotional disconnection, poor communication, and pressure may reduce desire. |
| Hormonal changes | Pregnancy, postpartum changes, perimenopause, menopause, and other endocrine factors may affect libido. |
| Physical health | Diabetes, cardiovascular disease, thyroid problems, chronic pain, neurological illness, and other conditions may affect sexual function. |
| Other medication | Several prescription and non-prescription medicines can affect sexual response. |
If the change is persistent or difficult to explain, see When a Change in Sexual Desire May Need Medical Support.
What if the Medication Is Helping and You Do Not Want to Change It?
This is a completely legitimate concern.
The choice is not always:
mental health
or:
sex life.
A medication may have helped enormously.
You may be functioning better.
Sleeping better.
Less anxious.
Less depressed.
And still be frustrated by sexual side effects.
That is something to bring into treatment rather than silently tolerate or solve alone.
A clinician can help weigh:
- how effective the current antidepressant is;
- how severe the sexual side effects are;
- whether those effects are improving or persistent;
- the risks and benefits of changing medication;
- other possible contributors to the sexual problem.
A medication can be helping your mental health and still be creating a side effect worth discussing. Those two truths do not cancel each other out.
How Should Couples Talk About Antidepressant-Related Low Libido?
Try to move the conversation away from blame.
Not:
You never want me anymore.
And not:
You'll just have to live with it.
A more useful conversation might sound like:
My sexual response has changed since I started treatment. I don't think this is about attraction, but I know it affects us. I want us to be able to talk about it without sex becoming something I have to prove.
The partner can also say:
I know this may be medication-related. I still miss our sexual connection, but I don't want to pressure you. Can we work out what intimacy feels comfortable while you talk to your doctor?
This protects both people.
The person taking medication is not forced to perform.
The partner's experience of sexual distance is not dismissed.
The sexual side effect may belong to one person's treatment, but the emotional impact can affect both partners. It is possible to treat it as a shared relationship issue without making either person responsible for providing unwanted sex.
For the wider communication issue, see How to Talk to Your Partner About Low Libido.
When Should Antidepressant-Related Sexual Changes Be Discussed With a Doctor?
You do not need to wait until the problem becomes severe.
Bring it up when:
- libido changed noticeably after starting medication;
- sexual function changed after a dose increase;
- you cannot reach orgasm when you previously could;
- erection difficulties have become persistent;
- lubrication or arousal has changed significantly;
- the sexual side effects are making you consider stopping medication;
- the change is affecting your relationship or quality of life;
- you are unsure whether the problem is depression, medication, or something else.
Sexual side effects are a legitimate part of medication review.
You are not wasting the doctor's time by mentioning them.
Low Libido on Antidepressants Does Not Automatically Mean Your Relationship Has Changed
Sexual response can change while love remains.
Attraction can remain.
Commitment can remain.
And the medication can still be important.
The useful task is working out which part of the sexual system changed.
Desire?
Arousal?
Orgasm?
Erection?
Sensation?
Or the emotional meaning that developed after those physical changes appeared?
When sexual function changes after antidepressants, do not rush to diagnose the relationship from the bedroom.

FAQ: Antidepressants and Low Libido
Can antidepressants lower your sex drive?
Yes. Some antidepressants can reduce sexual desire or affect arousal, orgasm, erection, lubrication, and sexual sensation. SSRIs are among the antidepressants more commonly associated with sexual side effects.
Can SSRIs cause low libido?
Yes. SSRIs such as sertraline, fluoxetine, citalopram, escitalopram, and paroxetine can cause sexual side effects in some people, including reduced desire and difficulty reaching orgasm.
Can antidepressants make it difficult to orgasm?
Yes. Delayed orgasm or difficulty reaching orgasm is a recognised sexual side effect of several antidepressants, particularly serotonergic medications.
Can antidepressants cause erectile dysfunction?
They can contribute to erection difficulties in some men. Erectile problems may also involve anxiety, depression, physical health, other medication, and cardiovascular or hormonal factors.
How do I know if low libido is from depression or antidepressants?
The timeline can help. If low desire existed before treatment, depression may already have been contributing. If sexual function changed clearly after starting or increasing medication, a medication effect may be more likely. A clinician can help review the pattern.
Should I stop my antidepressant if it is affecting my sex life?
Do not stop or change antidepressant medication on your own. Speak with the prescribing clinician about the sexual side effects and whether any treatment adjustments are appropriate.
Do antidepressant sexual side effects go away?
For some people sexual side effects improve as the body adjusts, while for others they remain troublesome during treatment. Persistent effects should be discussed with the prescriber.
Does low libido from antidepressants mean I am no longer attracted to my partner?
No. Medication can affect sexual desire or response while emotional attachment and physical attraction remain intact.
