Plasma concentrations of dapoxetine, tadalafil, and sildenafil were determined by liquid chromatography–tandem mass spectrometry. Tadalafil did not affect the pharmacokinetics of dapoxetine, whereas sildenafil increased the dapoxetine AUCinf by 22%; these effects were deemed not clinically important.
Data extraction
Most adverse events were mild in nature. Thus, dapoxetine has no clinically important pharmacokinetic interactions with tadalafil or dapoxetine 60 mg buy online sildenafil, and the combinations are well tolerated.

Getting the most from your treatment
Serotonin helps to delay a reaction in the areas of your brain responsible for ejaculation. In other words, Priligy can help you go for longer before climaxing. Other SSRIs are often prescribed to treat depression where medication needs to be taken daily to have an effect. Priligy is an on-demand treatment for PE. This means you take the medication when you need to and not every day.
Competing interests
Priligy is designed to be taken one to three hours before having sex. Priligy should not be taken more than once in any 24 hour period. Study data suggest that taking dapoxetine, Priligy’s active ingredient, allowed men to have intercourse for two to three times longer than before. The men involved in the studies also described an increase in both a sense of control over when they climaxed and in how satisfying sex was. Most men, around 80%, will see an improvement when taking Priligy.

| Side Effect | Frequency | Severity | Management Tips |
|---|---|---|---|
| Nausea | Common | Mild to moderate | Take with food, follow dose instructions |
| Dizziness | Common | Mild | Avoid driving after taking |
| Insomnia | Occasional | Mild | Use earlier in the day if sleep disturbances occur |

Among the multiple definitions and criteria for the diagnosis of PE, the most frequently cited are short time to ejaculation, inability to delay or control ejaculation and negative personal consequences (3-6).
- Dapoxetine is a quick-acting medication designed for on-demand use before sex.
- It is effective in delaying ejaculation and increasing satisfaction.
- The medication is generally safe when used as directed under medical supervision.
- It is important to consider psychological factors alongside medication treatment.
- Dapoxetine may be combined with counseling or therapy for better results.
- Discontinuing dapoxetine should be discussed with your doctor first.
PE can be subdivided into lifelong and acquired PE (7). Lifelong PE is defined by the International Society of Sexual Medicine (ISSM) as a male sexual dysfunction characterized by ejaculation that always or nearly always occurs before or within approximately one minute of vaginal penetration, the inability to delay ejaculation on all or nearly all vaginal penetrations, and negative personal consequences such as distress, bother, frustration and/or the avoidance of sexual intimacy (6). This definition is based on evidence that 80-90% of men with lifelong PE ejaculate within 60 seconds (8).
| Attribute | Description | Notes |
|---|---|---|
| Purpose | Delays ejaculation time during intercourse | Often prescribed for PE |
| Typical Dosage | 30 mg to 60 mg | Taken 1-3 hours before sex |
| Onset of Action | Within 1-3 hours | Peak effect approximately 1 hour after intake |
| Duration of Effect | 2 to 4 hours | Varies per individual |
| Common Side Effects | Nausea, dizziness, headache | Usually mild |
| Contraindications | Use with MAO inhibitors, severe cardiac issues | Consult doctor before use |
Acquired PE characteristically develops later in life after a history of normal sexual function and ejaculatory control (9).
- It's essential to follow the prescribed dosage to prevent side effects.
- Dapoxetine is a prescription medication, so consultation is necessary.
- Combining dapoxetine with certain antidepressants may increase serotonin syndrome risk.
- The drug is considered effective for many men but may not work for all.
- Using dapoxetine can enhance relationships impacted by premature ejaculation.
- Regular medical check-ups are recommended during treatment.
Acquired PE is usually associated with urologic or psychological problems (10). This form of PE can often be remedied by treating the underlying etiology (10). In 2006, two more PE subtypes, natural variable PE and premature-like ejaculatory dysfunction, were proposed (11). Natural variable PE is regarded as a normal variant of sexual performance, whereas premature-like ejaculatory dysfunction is defined as a complaint of PE superimposed on ejaculation time in the normal range (10). These new subtypes help physicians more precisely stratify patients and set treatment algorithms.
- Men should be aware of potential allergic reactions such as rash or swelling.
- Dapoxetine does not affect sexual desire directly.
- It is important to report any persistent or worsening side effects.
- Use caution when scaling doses up, only as advised by a healthcare professional.
- Avoid taking dapoxetine with other medications that affect serotonin levels.
- Stay informed about new research and updates on dapoxetine therapy.
Pharmacotherapy remains the basis of management of lifelong and acquired PE, whereas psychotherapy should be considered for patients with natural variable PE and premature like ejaculatory dysfunction (12).
