Dapoxetine

Dapoxetine is is the first fast-acting drug specifically developed and approved for the on-demand treatment of premature ejaculation. As a selective serotonin reuptake inhibitor, it increases serotonin levels to delay ejaculation. When taken before sexual activity, it helps to delay ejaculation, improve control, and reduce distress.

Sexual health is an important aspect of overall well-being. However, conditions such as premature ejaculation (PE) can cause frustration for many men and put a strain on relationships. Dapoxetine has been introduced as a medication designed to address this common concern. Approved in several countries, it gives men a practical way to take greater control and feel more confident during intimate moments. Unlike older treatments, which often involved complex regimens or produced inconsistent results, Dapoxetine is designed to be easy to use and effective, providing a modern solution to a long-standing issue.

Initially developed in the 1990s by Eli Lilly as a potential antidepressant, Dapoxetine acts as a selective serotonin reuptake inhibitor (SSRI). However, its rapid absorption and short half-life made it unsuitable for daily use, yet ideal for treating premature ejaculation. Acquired by Johnson & Johnson, it was repurposed and launched as Priligy in 2009, gaining approval in over 50 countries for on-demand treatment.

Large-scale studies and surveys, such as the Global Study of Sexual Attitudes and Behaviors, consistently report a worldwide prevalence of premature ejaculation of approximately 30% ^[1], highlighting the demand for effective treatments like Dapoxetine. A study conducted in Mumbai between 2012 and 2014 observed that Dapoxetine was prescribed to approximately 10.9% of patients with erectile dysfunction. It was also used in combination with other drugs, such as Sildenafil or Tadalafil, in around 5.8% of cases ^[2].

Dapoxetine is approved for the treatment of premature ejaculation in several countries, including New Zealand, Sweden, Austria, Finland, Germany, Spain, Italy, and Portugal. In these regions, it is the only licensed drug for the specific treatment of premature ejaculation. On January 20, 2012, the European Commission granted marketing authorization for Priligy (Dapoxetine) in 30 mg and 60 mg doses across member states ^[3]. The global premature ejaculation therapeutics market was valued at USD 2.45 billion in 2023, and is projected to grow at a CAGR of 8.74% during the forecast period, reaching USD 4.06 billion by 2029 ^[4].

What is Dapoxetine?

Dapoxetine is a pharmaceutical medication developed to treat premature ejaculation in men, which is defined as ejaculation occurring sooner than desired during sexual activity. Dapoxetine belongs to a class of drugs known as SSRIs ^[5] and is unique in that it acts quickly and is short-lived in the body, unlike other SSRIs which are typically used to treat depression or anxiety. Originally studied for mental health conditions, Dapoxetine was found to significantly delay ejaculation. This led to its approval in over 50 countries, including parts of Europe and Asia. However, it is not yet approved in the United States. Dapoxetine is designed to be taken as required, providing men with a convenient, targeted solution to improve sexual performance and satisfaction.

Unlike other SSRIs, which are used to treat depression and anxiety disorders, Dapoxetine is specifically developed and approved to treat premature ejaculation in adult men aged 18–64. Its unique characteristics are its rapid onset of action and short duration in the body. Multiple large-scale, randomized, double-blind, placebo-controlled phase 3 trials and meta-analyses have consistently shown that dapoxetine significantly increases intravaginal ejaculatory latency time (IELT) compared to placebo, improves all aspects of premature ejaculation and is generally well tolerated ^[6]. This pharmacokinetic profile enables it to be taken 'on demand', typically 1–3 hours before anticipated sexual activity, rather than requiring daily dosing as with traditional antidepressants. The aim is to delay ejaculation and improve control over it, thereby reducing distress related to the condition.

Generic Dapoxetine

Originally marketed under the brand name Priligy, Dapoxetine is now available in generic forms in many countries where it is approved. This offers men seeking treatment for premature ejaculation a more affordable alternative. Generic versions contain the same active ingredient (dapoxetine hydrochloride) and are subject to the same regulatory standards as the branded product to ensure they are equally safe and effective ^[7].

Depending on the manufacturer and region, these generics are typically sold under names such as Dapoxy, Sustinex, or simply Dapoxetine 60. The availability of generics has made the medication more accessible, particularly in markets where cost is a significant barrier. However, availability varies widely, and in some regions, only the branded version may be available. Caution is advised when buying Dapoxetine to ensure safe and informed transactions.

How it works

Dapoxetine is designed to help men delay ejaculation by targeting the neurological processes involved in the sexual response. As a SSRI, it works by adjusting the levels of serotonin, a neurotransmitter that plays a key role in mood, emotion, and ejaculation control. Unlike traditional SSRIs, which build up in the body over weeks, Dapoxetine is fast-acting and designed for on-demand use, making it an effective and safe treatment for premature ejaculation and a major advance in sexual medicine ^[8]. Its mechanism is both precise and temporary, minimising long-term effects on the body.

Here’s a step-by-step look at how Dapoxetine functions:

1. Increases serotonin levels: After ingestion, Dapoxetine is rapidly absorbed into the bloodstream, where it inhibits the reuptake of serotonin in the brain. This increases the availability of serotonin in key neural pathways, particularly those involved in regulating ejaculation.
2. Modulates ejaculatory reflex: Dapoxetine modulates the ejaculatory reflex by influencing the central nervous system, specifically the spinal cord and brain regions that control the reflex. This delays the signal that triggers ejaculation, enabling men to delay climax.
3. Quick action, short duration: Dapoxetine reaches peak blood concentration within one to two hours and is quickly cleared from the body, with a half-life of about 1.5 to two hours. This rapid clearance reduces the risk of prolonged side effects, making it ideal for use as required.
4. Improves control and confidence: By extending the time to ejaculation, Dapoxetine helps men to gain better control during sexual activity, which often leads to improved satisfaction for both partners and a reduction in performance-related stress.

This targeted approach distinguishes Dapoxetine from other treatments, offering a balance of efficacy and convenience. It does not alter libido or sexual sensation, and focuses solely on delaying ejaculation. This makes it a practical choice for men seeking to address premature ejaculation without making broader changes to their sexual experience.

Indications

Dapoxetine is primarily prescribed to treat premature ejaculation in adult men. It is intended for men who meet the relevant diagnostic criteria and wish to enhance their sexual performance and satisfaction. The medication is approved for this purpose in many countries, offering a targeted solution to a common issue affecting an estimated 20–30% of men at some point in their lives.

Dapoxetine is indicated for:

1. Men diagnosed with premature ejaculation: Specifically, men aged 18 to 64 with a consistent history of premature ejaculation, where ejaculation occurs with minimal stimulation and before desired.
2. Men seeking on-demand treatment: Dapoxetine is taken as needed, typically one to three hours before sexual activity, making it suitable for those who prefer a flexible, non-daily medication.
3. Men in good general health: It is prescribed to men without significant underlying conditions that would contraindicate its use, such as certain heart or liver issues. This is determined by a healthcare provider.

The medication is not intended for recreational use or for men without a premature ejaculation diagnosis. It is essential to consult a doctor to confirm that Dapoxetine is appropriate, as premature ejaculation can sometimes stem from psychological factors or other medical conditions that may require different treatments.

Side effects

As with any medication, Dapoxetine can cause side effects, though most men tolerate it well due to its short-acting nature. These effects are usually mild to moderate and often diminish as the body adjusts or with proper use under medical guidance ^[9]. As Dapoxetine is taken on an as-needed basis, side effects are less likely to accumulate than with daily medications.

Common side effects include:

• Nausea: A frequent complaint, often mild and temporary, occurring shortly after taking the dose.
• Dizziness or lightheadedness: Some men experience a feeling of unsteadiness, particularly at higher doses or if taken on an empty stomach.
• Headache: This is a common issue that can usually be managed with hydration or over-the-counter pain relief.
• Fatigue or tiredness: A sense of low energy may occur, typically resolving within a few hours.
• Dry mouth: This is less common, but has been reported by some users, and is often alleviated by drinking water.

Less common but more serious side effects which require immediate medical attention include:

• Fainting or severe dizziness: Rare cases of low blood pressure may cause fainting, especially when combined with alcohol or certain medications.
• Mood changes: Though uncommon, some men may experience anxiety, agitation or unusual mood shifts given Dapoxetine’s effect on serotonin.
• Vision or hearing changes: These are extremely rare, but any sudden changes should prompt a call to a doctor.

Most side effects resolve quickly due to Dapoxetine's short half-life, but men experiencing persistent or severe symptoms should consult their healthcare provider. To minimise risks, doctors often start with a lower dose (30 mg) and adjust it as necessary to ensure that the benefits outweigh any discomfort.

Interactions

While SSRI Dapoxetine is effective in treating premature ejaculation, it can interact with certain medications, substances and health conditions, which may affect its safety or effectiveness. As it affects serotonin levels and is metabolised by the liver, men must inform their healthcare provider of all medications, supplements and recreational substances they are taking before starting treatment. These interactions can range from mild to serious, so careful management is essential.

Key interactions to be aware of include:

• Other SSRIs or serotonin-modifying drugs: Combining Dapoxetine with antidepressants such as fluoxetine or sertraline, or other drugs that increase serotonin levels (e.g. tramadol), can increase the risk of serotonin syndrome. This is a rare but serious condition that can cause symptoms such as confusion, a fast heart rate or seizures.
• Monoamine oxidase inhibitors (MAOIs): These medications, which are used to treat depression or Parkinson's disease, must not be taken with Dapoxetine due to the risk of severe reactions. A 14-day gap is typically required between stopping an MAOI and starting Dapoxetine.
• CYP3A4 inhibitors: Drugs such as ketoconazole, ritonavir or grapefruit juice can slow the body's breakdown of Dapoxetine, increasing the risk of side effects such as dizziness or nausea. Doctors may adjust the dose or avoid these combinations.
• Alcohol: Drinking alcohol while taking Dapoxetine can increase the risk of side effects such as dizziness, fainting or impaired judgement. Men are advised to limit or avoid alcohol when taking this medication.
• Medications for erectile dysfunction: Although these are sometimes prescribed together, combining Dapoxetine with potency remedies such as Sildenafil (Super Kamagra, Cenforce D, Extra Super P-Force) or Tadalafil (Tadapox) requires caution as both can lower blood pressure, which can cause dizziness or fainting.

To prevent complications, men should provide their doctor with a complete medical history and list of current medications. Pharmacists can also check for potential interactions when dispensing Dapoxetine, ensuring that it can be safely incorporated into a patient’s treatment plan.

Contraindications

Dapoxetine is not suitable for everyone, and certain medical conditions or circumstances make its use unsafe. It is critical to identify these contraindications before starting treatment to avoid serious health risks. A thorough evaluation by a healthcare provider is necessary to ensure that Dapoxetine is appropriate, given that it affects serotonin levels and cardiovascular function. Men with specific health issues or who are taking certain medications may require alternative treatments for premature ejaculation.

Dapoxetine is contraindicated in the following cases:

• Heart conditions: Men with significant heart problems, such as heart failure, a recent heart attack or uncontrolled arrhythmias, should not use Dapoxetine due to its potential to affect blood pressure and heart rate.
• Severe liver impairment: Since Dapoxetine is metabolised by the liver, moderate to severe liver dysfunction can lead to an unsafe accumulation of the drug in the body.
• History of fainting or syncope: Men with a history of unexplained fainting or low blood pressure are at a higher risk of experiencing severe dizziness or fainting when taking Dapoxetine.
• Certain psychiatric conditions: Those with a history of mania, severe depression or bipolar disorder should avoid Dapoxetine as it may exacerbate these conditions due to its effects on serotonin.
• Use of specific medications: Dapoxetine cannot be taken with MAOIs, thioridazine or potent CYP3A4 inhibitors (e.g. ketoconazole) as these can cause dangerous interactions. A washout period is required after stopping such drugs.
• Allergy to Dapoxetine: Men with a known hypersensitivity to Dapoxetine or its components should not use it to avoid allergic reactions.
• Inappropriate age: Dapoxetine is not approved for use by men under 18 or over 64 years of age, as its safety and efficacy have not been established in these age groups.

Men with these conditions or circumstances should discuss alternative options with their doctor. Even in the absence of contraindications, a medical assessment ensures that Dapoxetine is used safely and effectively.

Onset and duration

Dapoxetine is designed to work quickly and have a short-term effect, making it ideal for treating premature ejaculation on demand. Unlike many medications that take days or weeks to work, Dapoxetine is fast-acting and leaves the body quickly, which is ideal for men who want flexibility in their treatment.

The onset of action typically occurs within 1–3 hours of taking the pill ^[8], with peak blood concentrations being reached around one to two hours after dosing. This rapid absorption enables men to take Dapoxetine shortly before sexual activity, providing effective ejaculatory control when needed. To optimise its effect, the medication should be taken with a full glass of water. It can be taken with or without food, though heavy meals may slightly delay absorption.

The duration of Dapoxetine's effect is relatively short, with a half-life of approximately 1.5 to 2 hours ^[10]. Most of the drug is cleared from the body within 24 hours, minimising the risk of lingering side effects. This short duration is a key advantage as it reduces the likelihood of systemic build-up and allows men to use the medication only when they anticipate sexual activity without the need for long-term daily dosing.

How to use Dapoxetine

Dapoxetine is designed for straightforward, on-demand use, making it a convenient option for men managing premature ejaculation. Proper use is essential to maximise its effectiveness while minimising potential side effects. Always follow the instructions of your healthcare provider, as dosing and timing are tailored to your individual needs and health conditions.

Here are the key guidelines for using Dapoxetine:

• Timing: Take Dapoxetine one to three hours before anticipated sexual activity to allow it to reach peak effectiveness. Do not take more than once in a 24-hour period.
• Dosage: The typical starting dose is 30 mg, which may be increased to 60 mg if needed and tolerated, as determined by a doctor. Never exceed the prescribed dose.
• Administration: Swallow the tablet whole with a full glass of water to aid absorption and reduce the risk of dizziness. The tablet can be taken with or without food, though a heavy meal may slightly delay its onset.
• Frequency: Dapoxetine is not intended for daily use. Only take it when sexual activity is planned, ensuring at least 24 hours between doses to avoid accumulation.
• Hydration: Stay well hydrated while taking Dapoxetine, as dehydration can increase the likelihood of side effects such as dizziness or fainting.
• Alcohol avoidance: Limit or avoid alcohol, as it can exacerbate side effects such as dizziness and low blood pressure, thereby reducing the safety and effectiveness of the medication.

Men should not adjust their dose or frequency without consulting their doctor, as improper use can lead to reduced efficacy or increased side effects. If a dose is missed or sexual activity does not occur, do not take an extra dose to compensate. Regular follow-ups with a healthcare provider can help ensure that the treatment remains effective and safe over time.

Who can use Dapoxetine

Dapoxetine is a targeted treatment for premature ejaculation, but it’s not suitable for all men. It is specifically designed for adult men who meet certain health and diagnostic criteria, ensuring both safety and effectiveness. A healthcare provider’s assessment is crucial in determining whether Dapoxetine is appropriate, as individual health conditions and medical history play a significant role in its suitability.

Dapoxetine is generally suitable for:

• Men aged 18 to 64: Dapoxetine is approved for adult men in this age range, as clinical studies have focused on this group, establishing its safety and efficacy ^[11].
• Men diagnosed with premature ejaculation: Those with a consistent pattern of ejaculating too quickly during sexual activity, typically within one minute of penetration, and who experience distress or relationship strain as a result.
• Men in good general health: Candidates should have no significant heart, liver or kidney issues, as these conditions can make Dapoxetine unsafe.
• Men seeking on-demand treatment: Those who prefer a medication that is only taken when needed rather than as part of a daily regimen are ideal candidates due to Dapoxetine's rapid onset and short duration.
• Men cleared of contraindicated medications: Those who are not taking drugs such as MAOIs, certain antidepressants or strong CYP3A4 inhibitors, as these can cause dangerous interactions with Dapoxetine.

Men with underlying psychological issues, such as anxiety or relationship problems, may still use Dapoxetine if premature ejaculation is a primary concern, but they may also benefit from counselling or therapy. Those with erectile disorder may be able to use Dapoxetine alongside other treatments, but this requires careful medical oversight. Men outside the approved age range, with contraindicated conditions or without a premature ejaculation diagnosis, should consult their doctor about alternative options to address their sexual health needs.

When to consider Dapoxetine

Dapoxetine is a practical solution for men dealing with premature ejaculation. However, deciding whether to take it depends on the impact of the condition and your personal health goals. As it is not a one-size-fits-all remedy, men should weigh its benefits against their specific circumstances, ideally with guidance from a healthcare provider. For many men, Dapoxetine becomes a compelling option when premature ejaculation significantly impacts their quality of life or relationships, and when other approaches have proven ineffective.

Consider Dapoxetine if you experience any of the following:

• Persistent premature ejaculation: You consistently ejaculate within one minute of penetration, or sooner than desired, despite trying to delay climax.
• Emotional or relationship distress: premature ejaculation causes you to feel frustrated, embarrassed, or tense with a partner, which impacts your self-confidence or intimacy.
• Limited success with nonmedical approaches: Techniques such as behavioural exercises (e.g. the stop-start method), pelvic floor exercises or counselling have not led to sufficient improvement.
• Preference for on-demand treatment: You want a medication that can be taken only when needed, fitting seamlessly into your lifestyle without requiring a daily commitment.
• Good overall health: You have no contraindicating conditions (e.g. heart disease or severe liver issues) or medications that would make Dapoxetine unsafe.

Dapoxetine may also be worth considering if you are seeking a medically proven way to enhance your sexual satisfaction and that of your partner. However, it is not suitable for everyone as a first step. Men who are new to addressing premature ejaculation might start with lifestyle changes or therapy, only resorting to Dapoxetine if these measures prove ineffective. Combined pharmacological and psychological therapy is the most promising intervention for treating both lifelong and acquired premature ejaculation, offering superior efficacy to drugs alone ^[12].

Alternatives

While Dapoxetine is an effective option for treating premature ejaculation, it’s not the only approach. Men who cannot use Dapoxetine due to contraindications, who prefer non-medication solutions, or who are keen to explore other methods can consider a range of alternatives. These options vary in approach, from behavioural techniques to other medications, and can be used alone or in combination depending on individual needs and medical advice.

Behavioural techniques:

• Stop-start method: Pausing sexual activity when nearing ejaculation to build control over time.
• Squeeze technique: Gently squeezing the penis to delay ejaculation; this is often practised with a partner.
• Pelvic floor exercises: Strengthening the pelvic floor muscles through Kegel exercises to improve ejaculatory control.
• Counselling or therapy: Working with a therapist to address psychological factors such as anxiety, stress, or relationship issues that contribute to premature ejaculation. Cognitive behavioural therapy or couples counselling can be particularly effective.

Topical anaesthetics:

• Lidocaine or prilocaine creams/sprays: These are applied to the penis to reduce sensitivity and delay ejaculation, but careful timing is required and they may affect partner sensation.
• Condoms with anaesthetic: These are specially designed condoms that contain numbing agents to achieve a similar effect.

Other medications:

• Off-label SSRIs: Antidepressants such as sertraline or paroxetine can delay ejaculation when taken daily, but they require long-term use and may have more side effects.
• Tramadol: This is an opioid painkiller that is sometimes prescribed off-label for premature ejaculation, but it carries risks of dependency and side effects.
• Lifestyle changes: Improving overall health through exercise, stress management and reducing alcohol and smoking can enhance sexual performance and control.
• Natural supplements: Some men try herbal remedies such as ginseng or L-arginine, but there is limited evidence for their effectiveness, and they should be discussed with a doctor to avoid interactions with other medications.

Each alternative has its benefits and limitations. Behavioural techniques and therapy are non-invasive, but they require time and consistency. In contrast, topical agents offer quick results, but they may reduce sensation. Other medications may be effective, but they come with different side effect profiles. Combining different approaches may help to achieve the best results.

Lifestyle tips for the best results

Dapoxetine can significantly improve control over premature ejaculation, but combining it with a healthy lifestyle can further enhance its effectiveness and improve overall sexual health. Making small, sustainable changes to daily routines can reduce stress, improve physical stamina and create a more satisfying intimate experience. Addressing both physical and psychological factors can help men maximise the benefits of Dapoxetine and feel more confident in their performance.

Here are some practical lifestyle tips to help you get the most out of Dapoxetine:

• Manage stress and anxiety: High levels of stress can exacerbate premature ejaculation. Practise relaxation techniques such as deep breathing, meditation or yoga to help you stay calm and focused, particularly before intimate moments.
• Exercise regularly: Engage in moderate physical activity, such as jogging, swimming or strength training, to improve cardiovascular health and stamina. Better overall fitness can enhance sexual endurance.
• Strengthen your pelvic floor muscles: Perform Kegel exercises by contracting and relaxing the muscles used to stop urination. Regular practice can improve ejaculatory control over time.
• Maintain a balanced diet: Eat nutrient-rich foods, such as fruits, vegetables, lean proteins and whole grains, to support energy levels and hormonal balance. Avoid excessive processed foods and sugar, as these can affect stamina.
• Limit alcohol consumption and avoid smoking: Excessive alcohol can reduce the effectiveness of Dapoxetine and increase side effects such as dizziness. Smoking can also impair blood flow and negatively affect sexual performance.
• Communicate with your partner: Openly discussing your preferences and concerns with your partner can reduce performance anxiety and create a more supportive environment, improving the overall experience.
• Get adequate sleep: Aim for seven to eight hours of quality sleep per night to regulate hormones and reduce fatigue, both of which can influence sexual health and the body's response to treatment.
• Stay hydrated: Drink plenty of water, especially when taking Dapoxetine, to minimise side effects such as dizziness and support overall bodily functions.

Incorporating these habits complements the use of Dapoxetine and promotes long-term well-being. Men should consult their healthcare provider to ensure that these lifestyle changes align with their treatment plan, especially if they are combining Dapoxetine pills with other therapies or exercises. Consistency is key to amplifying the medication’s benefits and contributing to a more fulfilling sex life.
