SSRI (Selective serotonin reuptake inhibitors) is a type of antidepressant traditionally used to treat major depressive disorder and anxiety disorders. Since some patients using it complained of a delay in ejaculation, some researchers in the early 90s got interested in its potential as a treatment for premature ejaculation. Doctors as an off-label treatment for premature ejaculation. Based on actual data, it’s the best premature ejaculation drug to delay ejaculation.
A Word of Caution
Before we start to talk about effective premature ejaculation pills and medication, we just want to be crystal clear about one thing. All the drugs listed here are strong medicine and available only via a doctor’s prescription. Never use a prescription drug for which you do not have a prescription. Your health is not something you want to risk, and taking medication without a professional medical advice poses serious health risks.
If you consider using drug treatment for premature ejaculation, please consult a physician and respect his instructions. This page’s goal is only to present the options available, but it isn’t a professional medical opinion. I’m not aware of every counter indication those drugs may have, neither your particular health condition. Your doctor is, that’s why he’s the one you should trust.
If you are looking for an over-the-counter product to treat premature ejaculation, delay creams, sprays or condoms could be effective solutions.
How SSRI Works
SSRI stands for serotonin-specific reuptake inhibitors. Also called serotonergic antidepressants, it’s a class of antidepressant that increases the serotonin level. If you are wondering what serotonin is, it’s a neurotransmitter. Neurotransmitters are the means of communication of your nervous system.
The way in which SSRI delay ejaculation is complicated and not entirely understood. One of the believed cause of premature ejaculation is a diminished serotonin level. Scientists suspect that serotonin plays a role in ejaculation inhibition. Without a functioning serotonin level, your body triggers the ejaculation reflex too soon. Therefore, a drug like SSRI which increase your serotonin level also delays ejaculation.
There are different types of SSRI. Paroxetine, sertraline, fluoxetine, citalopram, and fluvoxamine are the most common type of SSRI. While most of them delay ejaculation, they aren’t all as effective. Paroxetine is the most effective of all.1
About Efficacy Measure
The efficacy of a premature ejaculation drugs is measured with a unit called ITEL fold increase. You can read more on how different treatment are compared together here. In short, IELT stands for Intravaginal Ejaculation Latency Time. It’s a stopwatch measure of the intercourse time, from penetration start to ejaculation. We calculate a couple average IELT by timing all their sexual relations on a specified period.
The fold increase is calculated like this: (IETL after / IETL before) – IETL before. For example, let’s take a couple that has a 1 min average IELT that increases to 2 min after treatment. It represents a 1-fold increase: (2/1) – 1 = 1. If it increases to 3 min, it’s a 2-fold increase: (3/1) – 1 = 2.
The Most Effective SSRI for Premature Ejaculation
Paroxetine, sertraline, fluoxetine, citalopram, and fluvoxamine are the most common type of SSRI. While most of them delay ejaculation, they aren’t all as effective. Paroxetine is the most effective one with a mean IELT fold increase of 8.8 for a dose that ranges from 10 to 40mg per day1. Fluvoxamine is the only SSRI that doesn’t seem to delay ejaculation2.
The drug efficacy continues as long as the user take it, but sometimes the delay effect can diminish after a couple of month1. Also, based on the clinical experience of an expert, some men (around 20%) do not experience any ejaculation delaying effect3.
You can find here a table that summarizes the mean IELT fold increase for several SSRI type1-4.
|SSRI Type||Dose||IELT Increase|
|Fluvoxamine||Do not have any ejaculation delay effect|
|Dapoxetine||30-60 mg/1-3h before sex||2.5-3.0|

SSRI Usage for Premature Ejaculation
There is two type of drug usage for premature ejaculation: daily and on-demand. On-demand usage drugs are pills that you need to take 2 hours before having sex. Daily usage drugs are pills that you take each day for a prolonged effect.
Most SSRI are daily usage drugs. Paroxetine, sertraline, and fluoxetine all show a better efficacy with a daily usage.
The way we understand how SSRI works, on-demand use of SSRIs probably won’t be as effective as daily usage. Indeed, animal studies don’t show any significant improvement on ejaculation time from on-demand SSRI usage10. However, a specific short-term action SSRI have been specially developed to treat premature ejaculation. It’s called Dapoxetine. If you want more information on an on-demand drug for PE, you can read here our dapoxetine for premature ejaculation review.
SSRI Side Effect
All SSRIs have potential side effects., including weight gain6 and an increased risk of bleeding7, but also more serious one, albeit very rare, like priapism8. Please note that this isn’t a complete list of all SSRIs potential side effects. For a full list of all known side effects, please consult a professional medical opinion, like a doctor or a pharmacist.
Still, specialists note that these side effects are generally mild and disappear after a couple of weeks4.
SSRI Discontinuation Syndrome
It’s also important to note that SSRIs could have discontinuation syndrome if you stop taking the drug. Therefore, it’s better to stop taking the medication gradually. Tremor, shock-like sensations when turning the head, nausea and dizziness are potential discontinuation syndrome9. To avoid those, you need to talk to your doctor first if you want to stop taking the medication. He will lay out a withdrawal plan for you.
Wish for Pregnancy
Since we don’t know a lot about SSRIs effect on spermatozoid, some specialists suggest stopping SSRI usage gradually for men who are looking to father a child. Since the spermatozoa take some time to regenerate, it’s advised to use a condom for three months after the drug stoppage2.
