(2006) Efficacy and tolerability of dapoxetine in treatment of premature ejaculation: an integrated analysis of two double-blind, randomized controlled trials Lancet 368: 929–37 The integrated process statement sets out the process NICE uses to select topics for the evidence summaries: new medicines and how the summaries are developed, quality assured and approved for publication.

How it Works

Dapoxetine is the only medicine licensed in the UK for the treatment of premature ejaculation, although other treatments are used off-label for this indication. The General Medical Council advice to use a licensed medicine whenever possible should be taken into consideration. The manufacturer has estimated that based on a GP-registered population of 100,000 people, 5851 men aged 18 to 64 will be affected by premature ejaculation with 1151 men severely affected (A. Menarini Farmaceutica Internazionale: personal dapoxetine spain communication January 2014). The manufacturer further estimates that 25% of the men severely affected by premature ejaculation will seek treatment and 70% of those seeking treatment could be prescribed dapoxetine.

Phosphodiesterase type 5 inhibitors

The manufacturer therefore estimates that based on a GP-registered population of 100,000, 202 men aged 18 to 64 may potentially be prescribed dapoxetine over a 5-year period (A. Menarini Farmaceutica Internazionale: personal communication January 2014). The manufacturer estimated that in 2013 approximately 75% of European sales of dapoxetine were for the 30 mg strength. Dapoxetine for premature ejaculation was not considered appropriate for a NICE technology appraisal and is not currently planned into any other work programme. There is no NICE guidance on premature ejaculation.

Ian Pearce, Consultant Urological Surgeon, Honorary Senior Lecturer, University of Manchester, Manchester Royal Infirmary Mike Foster, Consultant Urologist, Heart of England NHS Trust Dapoxetine is a medicine used for the treatment of premature ejaculation (a sexual dysfunction in which a dapoxetin sildenafil man ejaculates too quickly during sexual intercourse).

• Dapoxetine helps improve sexual performance and decrease performance anxiety.
• It is a part of a broader treatment approach for premature ejaculation.
• Not recommended for men with a history of seizures or heart issues.
• Dapoxetine's effects may vary depending on individual health factors.
• Combining dapoxetine with other medications should only be done under supervision.
• Always follow dosage instructions to ensure safety and efficacy.

This medicine helps in increasing the time taken to ejaculate and achieving better control over ejaculation during sexual intercourse. Dapoxetine has some side effects like dizziness, headache, nausea, and sweating.

• Combining dapoxetine with recreational drugs can be dangerous and is not recommended.
• Dapoxetine can improve quality of life in men with PE.
• Always consult a healthcare provider before starting or stopping medication.
• Maintain open communication with your partner about treatment options.
• Lifestyle adjustments, like reducing stress, can complement medication treatment.
• Regular health screenings are advised during dapoxetine therapy.

These side effects may subside by themselves. Consult your doctor if they bother you for a long time or become severe. Avoid taking this medicine if you are allergic to it.

Dapoxetine should only be used if you are diagnosed with premature ejaculation.

It can be taken with or without food as instructed by your doctor. It is usually taken as needed, one to three hours before sexual activity. It is not intended for regular daily use.

How to take dapoxetine tablets

In this approach, regardless of when a patient left the trial (for example, after week 1, week 6 or week 12), the last available result for that patient was carried forward and analysed as though it were the result at the study end. As stated in the summary of product characteristics, the efficacy and safety of dapoxetine in men with both premature ejaculation and erectile dysfunction treated with both dapoxetine and phosphodiesterase type 5 inhibitors (for example, sildenafil) has not been established. The summary of product characteristics states that dapoxetine should not be used in men taking phosphodiesterase type 5 inhibitors. There are limited data available on the safety and efficacy of dapoxetine 'on demand' for longer than 24 weeks. The European Association of Urology 2014 guidelines on male sexual dysfunction recommend that pharmacological treatment options include 'on demand' dapoxetine, daily use of a longer-acting selective serotonin reuptake inhibitor (SSRI) [off-label use], daily use of clomipramine (off-label use), 'on demand' topical local anaesthetic agents (off-label use) and 'on demand' tramadol (off-label use).

Recent Post

Because longer-acting SSRIs such as citalopram, fluoxetine or paroxetine have a longer onset of action than the shorter-acting dapoxetine they need to be taken on a daily basis and cannot be used as an 'on demand' treatment. The European Association of Urology 2014 guidelines on male sexual dysfunction states that in men for whom premature ejaculation causes few if any problems treatment should be limited to psychosexual counselling and education. The guidelines recommend that before beginning treatment, it is essential to discuss the expectations of treatment thoroughly. Various behavioural techniques have demonstrated benefit in treating premature ejaculation and are indicated for men who are uncomfortable with pharmacological therapy. In lifelong premature ejaculation, the European guidelines state that behavioural techniques are not recommended for first-line treatment because they are time-intensive, require the support of a partner and can be difficult to do.

Mr Suhail Jamil

The guidelines recommend that pharmacological treatment options include 'on demand' dapoxetine and daily use of a longer-acting SSRI such as citalopram, fluoxetine or paroxetine (off-label use) or daily use of clomipramine (off-label use). Dapoxetine is taken 'on sildenafil and dapoxetine demand' approximately 1 to 3 hours before anticipated sexual activity. This may reduce the incidence of SSRI-related adverse effects compared with the off-label use of once-daily longer acting SSRIs, although there are no direct RCTs to provide evidence for this. However, some men may prefer to take a daily dose which may allow more spontaneity than a planned 'on demand' treatment. Dapoxetine is licensed for treating premature ejaculation in adult men aged 18 to 64 years. Avoid taking more than one tablet within 24 hours. Dapoxetine may not be suitable for everyone.

About Priligy

The summary of product characteristics states that dapoxetine should only be prescribed to men who meet all the following criteria: An intravaginal ejaculatory latency time of less than 2 minutes and An intravaginal ejaculatory latency time of less than 2 minutes and Persistent or recurrent ejaculation with minimal sexual stimulation before, on, or shortly after penetration and before the man wishes and Persistent or recurrent ejaculation with minimal sexual stimulation before, on, or shortly after penetration and before the man wishes and Marked personal distress or interpersonal difficulty as a consequence of premature ejaculation and Marked personal distress or interpersonal difficulty as a consequence of premature ejaculation and A history of premature ejaculation in the majority of intercourse attempts over the prior 6 months. Therefore, men will need to be appropriately assessed and given a diagnosis of premature ejaculation in line with the above criteria before dapoxetine can be considered. In addition, the summary of product characteristics states that a careful appraisal of the individual benefit/risk ratio should be carried out after the first 4 weeks of treatment (or at least after 6 doses of treatment) to determine whether continuing treatment is appropriate. If dapoxetine is continued, the benefit/risk balance should be re-evaluated at least every 6 months. Consideration will need to be given to how treatment efficacy can be assessed given the subjective nature of efficacy outcomes.

It supports control, not “perfection”

Premature ejaculation can occur in conjunction with erectile dysfunction and the European Association of Urology 2014 guidelines on male sexual dysfunction states that if premature ejaculation is secondary to erectile dysfunction then the erectile dysfunction should be treated before or at the same time as the premature ejaculation. It should be noted however, that the summary of product characteristics states that dapoxetine should not be used in men taking phosphodiesterase type 5 inhibitors (for example, sildenafil) as this increases the risk of syncope. For a number of men pharmacological treatment of premature ejaculation will not be acceptable. A prospective observational study from a single clinical centre in Italy (Mondaini et al. 2013) assessed the acceptance and discontinuation rates of 'on demand' dapoxetine 30 mg (titrated to 60 mg after 3 months if low efficacy) in 120 men with lifelong premature ejaculation.

Not recommended for primary or secondary care prescribing

Twenty-four (20%) of the men decided not to start dapoxetine. Fear of using a 'drug' was the most frequently reported reason for treatment non-acceptance (50%). In addition, the majority of men who took dapoxetine discontinued treatment. The main reasons for treatment discontinuation were efficacy below expectations, side effects and costs. Out of the 96 men who decided to start dapoxetine, only 10 men were continuing the treatment after 1 year. Inform your doctor if you have seizures (fits), mental conditions, or eye, heart, liver, and kidney problems.
