In the official clinical trials, about 6 in 100 men taking citalopram reported delayed ejaculation. When a team of Spanish researchers asked patients directly, with a structured questionnaire, nearly 73 in 100 people on citalopram reported some kind of sexual change. The pill was the same. The gap comes from who was asking and how. That gap is why Celexa sexual side effects are so often missed, and why so many people put up with them quietly. This guide sorts them into three tiers: what is common, what is serious, and when to call a doctor.
Quick answer: Celexa (citalopram) commonly lowers sex drive, delays or blocks orgasm, delays ejaculation and can make erections or arousal harder. These effects are usually not dangerous and can often be managed. Two problems need fast attention: an erection that lasts 4 hours or more (go to the ER) and sexual numbness that continues after the drug is stopped. Do not stop Celexa on your own. Talk to your prescriber first, because there are real options.
Celexa is the brand name of citalopram, an SSRI antidepressant made by AbbVie (formerly Allergan). It is prescribed for depression and is often used off-label for anxiety. If you want the full list of side effects beyond the bedroom, start with our overview of common and serious Celexa side effects. This post stays focused on sex.
How common are Celexa sexual side effects? The label vs. real life
Two very different sets of numbers exist. Both are true; they measure different things.
What the Celexa label reports
The Celexa prescribing information pools the placebo-controlled depression trials. In those studies, people mostly reported side effects on their own, without a detailed sexual-health questionnaire. Here is what showed up:
| Sexual side effect | Who | Celexa | Placebo |
|---|---|---|---|
| Abnormal ejaculation (mostly delay) | Men (425 on Celexa, 194 on placebo) | 6.1% | 1% |
| Decreased libido | Men | 3.8% | Under 1% |
| Impotence (erectile difficulty) | Men | 2.8% | Under 1% |
| Decreased libido | Women | 1.3% | Not listed |
| Anorgasmia (no orgasm) | Women | 1.1% | Not listed |
The label itself warns that these figures probably undercount the problem. It notes that patients and doctors are often reluctant to talk about sex, and it asks prescribers to check on sexual function before and during treatment because people may not mention it on their own. In one fixed-dose study, impotence also became more common as the dose went up.
What happens when researchers ask directly
A large Spanish multicenter study led by Montejo and colleagues, published in the Journal of Clinical Psychiatry in 2001, followed 1,022 outpatients and asked each one specific questions about desire, orgasm, ejaculation, erections and satisfaction. The results looked very different from the label:
- Citalopram: 72.7% (48 of 66 patients) had some form of sexual dysfunction, the highest rate in the study.
- Paroxetine: 70.7%. Venlafaxine: 67.3%. Sertraline: 62.9%. Fluvoxamine: 62.3%. Fluoxetine: 57.7%.
- Mirtazapine: 24.4%. Nefazodone: 8%. Moclobemide: 3.9%.
- Across all drugs, about 4 in 10 people with sexual side effects said they tolerated them poorly.
Keep the citalopram group size in mind: 66 people is small, so the exact figure is less precise than it sounds. Still, the overall message holds up across studies. When people are asked plainly, sexual side effects on SSRIs like citalopram are common, not rare. If this is happening to you, you are not unusual and you are not imagining it.
One more point: depression itself often lowers desire and pleasure. Some sexual changes predate the medicine. A useful question for yourself is, “Was this happening before I started Celexa, or did it start or get worse after?” Your answer helps your prescriber sort it out.
Tier 1: common Celexa sexual side effects
These everyday effects can strain a relationship, but they are not emergencies, and most can be improved. MedlinePlus lists them among the side effects to report to your doctor if they are severe or do not go away.
Low libido (reduced sex drive)
Many people describe this as “the switch just isn’t there.” You may still love your partner and enjoy closeness, but the spark of wanting sex fades. It can show up in anyone, and it is often the first change people notice.
Delayed orgasm or anorgasmia
This is the classic SSRI effect. Arousal may feel normal, but reaching orgasm takes much longer, needs more stimulation, or does not happen at all. When orgasm does come, some people say it feels weaker or “muted.” This affects all genders and is one of the most common reasons people quietly stop their antidepressant.
Ejaculation delay
In men, delayed ejaculation was the most frequently reported sexual problem in the Celexa trials. Sex may go on far longer than wanted, which can cause soreness or frustration for both partners.
Erectile difficulty
Some men find erections harder to get or keep. In the label data, this was less common than ejaculation delay and seemed to rise with dose. Performance anxiety can then make it worse.
Reduced arousal or lubrication
For women especially, the body may respond more slowly to touch. Less natural lubrication, less genital sensitivity and slower physical arousal are all reported with SSRIs. This can make sex uncomfortable, which then lowers desire further. A good water- or silicone-based lubricant is a simple first fix while you work on the bigger picture.
What men on Celexa tend to notice
For men, the pattern tends to follow the label’s order. Delayed ejaculation leads, then lower desire, then erection problems. A few practical points:
- Ejaculation delay is the most common complaint. In the trials, men on Celexa reported it about six times as often as men on placebo.
- Erections can be helped. Erection medicines such as sildenafil (Viagra) and tadalafil (Cialis) have trial evidence in men on SSRIs. Our Viagra vs. Cialis comparison explains how they differ in timing and duration. Ask your prescriber before adding either one.
- Alcohol makes it worse. Drinking can further blunt erections and orgasm and can deepen depression. See our guide to mixing Celexa and alcohol.
- Know the priapism warning. It is rare, but priapism (a painful, unwanted erection that will not go away) is listed in the Celexa label’s post-marketing reports. More on that in Tier 2.
- Other medical causes still count. Diabetes, high blood pressure, heart disease and low testosterone can all cause erection trouble. A new problem after starting Celexa is worth a broader check-up, not just a medicine tweak.
What women on Celexa tend to notice
The label numbers for women look tiny (about 1%), but that is mostly a reporting problem. Women’s sexual concerns have historically been asked about less often, and questionnaires in older trials did not always cover arousal or lubrication. Common experiences include:
- Orgasm that takes much longer or does not happen. This is the most widely described change.
- Lower desire and fewer spontaneous sexual thoughts.
- Slower physical arousal, less lubrication and sometimes less sensitivity.
- Overlap with life stages. Perimenopause, menopause, postpartum changes and hormonal birth control can all affect desire and lubrication. It helps to tell your prescriber about any of these.
There is good news here, too. The two best-studied non-drug and add-on strategies for women on antidepressants come from trials in women: scheduled exercise before sex, and a higher dose of bupropion added to the SSRI. Both appear in the management table below. If you are pregnant or planning a pregnancy, check our page on Celexa during pregnancy and breastfeeding before any medicine changes.
Tier 2: serious sexual side effects of Celexa
These are uncommon. Most people on citalopram will never have them. But they are the ones you should not wait out.
Priapism: an emergency after 4 hours
Priapism is a prolonged erection that is not linked to sexual desire and does not go down. It is often painful. The Celexa label lists it among reports received after the drug came to market, which means it is rare and the true rate is unknown. The risk may be higher if Celexa is combined with other drugs that can cause it, such as trazodone or erection medicines.
What to do: If an erection lasts 4 hours or longer, call 911 or go to the nearest emergency room. Do not wait for it to pass. Without prompt treatment, priapism can permanently damage erectile tissue. Emergency teams treat it routinely, and early care works best.
Post-SSRI sexual dysfunction (PSSD)
For most people, sexual side effects fade after an SSRI is stopped. A small number report that the problems continue for months or longer after their last dose. This is called post-SSRI sexual dysfunction, or PSSD.
In May 2019, the European Medicines Agency’s safety committee (PRAC) reviewed the reports and recommended updating the product information for SSRIs and SNRIs, citalopram included, to say that long-lasting sexual dysfunction has been reported even after the medicine was stopped. You can read the New Zealand Medsafe committee’s review of the PRAC decision for background. The current US Celexa label does not include a specific PSSD warning.
What we know and do not know:
- It appears to be rare, but no one has a reliable rate.
- The cause is not understood, and there is no proven treatment yet.
- Reported symptoms include low or absent desire, weak or pleasureless orgasm, reduced genital sensation and, for some, a broader emotional flatness.
This is not a reason to panic or to stop citalopram suddenly. Untreated depression carries serious risks of its own, and stopping abruptly can cause discontinuation symptoms (see our guide to Celexa withdrawal and tapering). It is a reason to speak up early if sexual side effects bother you, rather than living with them for years.
Genital numbness
Some people describe the genitals feeling “dull,” “rubbery” or numb, with touch registering as pressure rather than pleasure. Reduced genital sensitivity is one of the most frequently described PSSD symptoms in patient reports. While you are still taking Celexa, it may simply be part of the medicine’s effect. Still, treat it as a step up from ordinary low libido. Tell your prescriber, and mention it again if it lingers after any dose change or after stopping.
Tier 3: when to call a doctor about Celexa sexual side effects
Use this checklist. It runs from most urgent to least urgent.
Call 911 or go to the ER now if
- An erection lasts 4 hours or more, or is painful and will not go down.
- You took an erection medicine and have chest pain, fainting or sudden vision or hearing loss.
- You have high fever, severe muscle stiffness, confusion and a racing heart. These can be signs of serotonin syndrome, which can happen if another serotonin drug is added.
Call your prescriber within a day or two if
- Sexual side effects are making you want to skip doses or stop Celexa.
- You have new genital numbness or loss of sensation.
- Sexual problems are causing serious distress, relationship conflict or worsening mood.
- Sexual problems continue weeks after you have stopped citalopram.
Bring it up at your next appointment if
- You have mild, steady changes in desire, orgasm or ejaculation that are annoying but manageable.
- You want to know whether a different dose or medicine might be easier on your sex life.
- You are planning to try an erection medicine or an over-the-counter supplement and want to check it is safe with Celexa.
Mood check: Celexa carries a boxed warning about suicidal thoughts and behavior in people 24 and younger. If frustration about side effects is feeding hopelessness, or you have thoughts of harming yourself, call or text 988 (the Suicide & Crisis Lifeline in the US) any time, and let your prescriber know. If you are in immediate danger, call 911.
Why citalopram affects your sex life
Sex depends on a balance of brain chemicals and on healthy blood flow and nerve signals. Citalopram shifts that balance in a few ways. Keeping it simple:
- More serotonin acts like a brake. Citalopram works by keeping more serotonin active between nerve cells. That helps mood, but serotonin also tends to slow sexual responses, especially orgasm and ejaculation. That is why delayed orgasm is so typical.
- Less dopamine means less “want.” Dopamine drives motivation and desire. Higher serotonin can damp down dopamine signaling, which may explain the drop in libido. This is also why bupropion, which boosts dopamine and norepinephrine instead, has a lower sexual side-effect profile.
- Prolactin can rise. In some people, SSRIs nudge up prolactin, a hormone that can lower desire. This is usually mild.
- Genital sensation and blood flow. Serotonin also acts outside the brain, on nerves and blood vessels involved in arousal. This may contribute to erection trouble, less lubrication and reduced sensitivity.
Because these effects follow serotonin levels, they can change with dose. That is part of why dose and timing are among the first things a prescriber looks at. For more on dose ranges and the 40 mg maximum, see our Celexa dosage guide.
Managing Celexa sexual side effects: options to discuss with your prescriber
No single fix works for everyone, and the research is thinner than it should be. A 2022 Cochrane review of 23 randomized trials called the evidence limited, while finding a few strategies that stand out. Use the table below as a menu to take to your appointment, not as a do-it-yourself plan. Every one of these involves your prescriber.
| Option | What it involves | Evidence and caveats |
|---|---|---|
| Watchful waiting | Staying on the same dose for a few more weeks to see if effects ease | Some people adapt, but many do not. Reasonable early on if effects are mild. Not ideal if distress is high. |
| Dose reduction | Lowering to the smallest dose that still controls symptoms | The label found impotence rose with dose, so a lower dose may help. Risk: depression or anxiety may return. |
| Timing the dose | Planning sex for when blood levels are lowest, often just before the daily dose | Practical, low-risk idea. Citalopram’s roughly 35-hour half-life means levels stay fairly steady, so gains may be modest. |
| Switching medicine | Moving to an antidepressant with lower sexual side-effect rates, such as bupropion, mirtazapine or vortioxetine | Bupropion did not differ from placebo in a 2009 meta-analysis. Mirtazapine had about a third of citalopram’s rate in the Montejo study. Vortioxetine beat escitalopram in a switch trial. Each has its own side effects. |
| Bupropion add-on | Keeping Celexa and adding bupropion | Cochrane found benefit for women at 150 mg twice daily, not once daily. Can raise anxiety and seizure risk in some people. |
| PDE5 inhibitors | Adding sildenafil (Viagra) or tadalafil (Cialis) before sex | Best evidence in men. Helps erections and, in one trial, orgasm and satisfaction. Not safe with nitrates. |
| Drug holiday | Skipping doses for a weekend | Studied only for sertraline, paroxetine and fluoxetine, not citalopram. Risks withdrawal symptoms and relapse. Generally not advised. |
| Exercise before sex | About 20 minutes of moderate-to-vigorous exercise shortly before sexual activity | Trials in women on antidepressants showed better arousal and desire. Low risk, and good for mood too. |
Switching: which antidepressants are gentler on sex?
A 2009 meta-analysis by Serretti and Chiesa found that citalopram, sertraline and paroxetine all caused significantly more sexual dysfunction than placebo, while bupropion did not. Mirtazapine also showed no significant difference from placebo in that analysis, though with less data behind it. Vortioxetine (Trintellix) has its own evidence: in an eight-week trial of 447 adults switching off citalopram, paroxetine or sertraline because of sexual side effects, vortioxetine improved sexual function scores more than escitalopram did, and the FDA added these results to its label, according to Takeda’s 2018 announcement.
Switching to another SSRI is less likely to help, since the mechanism is the same. Our Celexa vs. Lexapro comparison covers how a close relative stacks up. Mirtazapine is often linked to weight gain and drowsiness, and bupropion is not a good fit for everyone with anxiety, so the “best” switch depends on your full picture. Any switch should be planned by your prescriber, usually with a cross-taper.
Erection medicines: the sildenafil evidence
The landmark study is Nurnberg and colleagues’ 2003 randomized trial in JAMA. It enrolled 90 men whose depression was in remission but who had sexual side effects from an SSRI. As summarized in American Family Physician, men taking sildenafil improved significantly on erection, ejaculation, orgasm and overall satisfaction compared with placebo. News coverage at the time reported that about 55% of the sildenafil group felt much or very much improved, versus about 4% on placebo.
The Cochrane review later confirmed that adding sildenafil or tadalafil appears to work for erectile problems in men on antidepressants. These drugs are not safe with nitrate heart medicines, and they need a check that your heart is healthy enough for sex. Your prescriber or pharmacist can confirm whether they suit you.
Why drug holidays are a poor fit for citalopram
A small 1995 study by Rothschild in the American Journal of Psychiatry had 30 patients skip their SSRI from Thursday morning to Sunday noon for four weekends. Sexual function improved on sertraline and paroxetine but not on fluoxetine, which lingers in the body much longer. Citalopram was not studied.
Citalopram’s half-life sits in between, so no one knows how a holiday would play out. Skipping doses also invites discontinuation symptoms such as dizziness, irritability and “brain zaps,” and the study was small and not randomized. For these reasons, weekend holidays from Celexa are generally not recommended. Do not try one without your prescriber.
Exercise right before sex
This one surprises people. Researchers Tierney Lorenz and Cindy Meston at the University of Texas found that women on antidepressants who did about 20 minutes of moderate-to-vigorous exercise just before a sexual stimulus had better genital arousal. Their later at-home trial with 52 women showed that exercising right before sex improved desire, and helped overall sexual function in women who had dysfunction at the start. Summaries of both studies are on the Meston lab’s research page. A short burst of exercise seems to prime the body’s arousal system, and it helps mood too.
How to bring this up with your doctor
Prescribers hear about sexual side effects every week, and the Celexa label tells them to ask. Still, the first sentence is often the hardest. Read this from your phone if it helps.
Script you can use: “I want to talk about a side effect that’s hard to bring up. Since starting citalopram [or since my dose went to ___ mg], I’ve noticed [low desire / trouble reaching orgasm / delayed ejaculation / erection problems / less sensation]. It started about ___ weeks ago. On a scale of 1 to 10 it bothers me about a ___. My mood is [better / the same / worse]. I don’t want to stop the medicine on my own. What are my options: changing the dose, switching, or adding something?”
A few extra tips make the conversation more useful:
- Bring a short timeline. When you started Celexa, any dose changes, and when the sexual changes began.
- Say how much your mood has improved. If Celexa is working well, your prescriber may favor an add-on. If it is only partly working, a switch may make more sense.
- List every medicine and supplement. Include blood pressure pills, birth control, other antidepressants, trazodone, and anything you are thinking of buying online.
- Ask what to expect. “How long should we give this change before trying something else?” is a fair question.
Your primary care doctor can handle this conversation; you do not need a psychiatrist to start. If you take citalopram mainly for anxiety, say so, since it changes which alternatives make sense (see using Celexa for anxiety).
Talking with your partner
Silence is often harder on a relationship than the side effect. A partner who does not know about the medicine may assume they are no longer wanted. Some approaches that help:
- Name the cause. Something like, “My medicine is affecting my body’s response. It isn’t about you, and I’m working on it with my doctor.”
- Pick a calm moment. Not in bed right after a frustrating attempt. A walk or a quiet evening works better.
- Widen the definition of intimacy. Touch, massage, cuddling and time together without the goal of orgasm can keep closeness alive and take pressure off.
- Plan, don’t just wait for spontaneity. Scheduling sex can sound unromantic, but it lets you use tips like exercising beforehand or timing an erection medicine.
- Go together. Some couples bring the partner to the appointment, or see a couples or sex therapist for a few sessions.
Frequently asked questions
Do Celexa sexual side effects go away?
Often, yes, though not always on their own. Some people adapt over a few weeks, while many find the effects continue as long as they take the same dose. For most people, sexual function returns after a dose change, a switch or stopping the drug under medical guidance. A small number report lasting problems after stopping (PSSD), which is why it is worth raising concerns early rather than waiting.
Is Celexa worse for sexual side effects than other SSRIs?
It is in the same range as other SSRIs. In the 2001 Montejo study, citalopram had the highest rate (72.7%), but paroxetine was very close at 70.7%, and the citalopram group was small. Bupropion, mirtazapine and vortioxetine are generally associated with fewer sexual side effects. Your prescriber can weigh those options against your other symptoms and health conditions.
Can I take Viagra or Cialis with Celexa?
Many men can, and trials show sildenafil and tadalafil help erections in men taking SSRIs. They are not safe with nitrate heart medicines and may not suit people with certain heart or eye conditions. Ask your prescriber or pharmacist to check your full medication list first. Seek emergency care for any erection lasting 4 hours or more.
Should I stop Celexa if it is ruining my sex life?
Not on your own. Stopping citalopram suddenly can cause discontinuation symptoms and raise the risk of depression or anxiety coming back. Tell your prescriber how much the side effects bother you; there are several options, from dose changes to switching or add-ons. If mood worsens or you have thoughts of self-harm, call or text 988 right away.
The bottom line on Celexa sexual side effects
Celexa sexual side effects are far more common than the label’s single-digit percentages suggest, and they are a fair thing to bring up. Think in tiers. Low desire, delayed orgasm, delayed ejaculation, erection trouble and reduced arousal are common and usually manageable. Priapism lasting 4 hours is an emergency, and numbness or problems that persist after stopping deserve prompt attention. In between, a clear conversation with your prescriber opens up real choices: a lower dose, a switch to bupropion, mirtazapine or vortioxetine, a bupropion or PDE5 add-on, or something as simple as exercise before sex. You should not have to choose between feeling better and having a sex life. Ask for both.
