Studies show that taking Dapoxetine increases dapoxetin sildenafil the time between ejaculation and ejaculation in the vagina. This makes it easier for men to control ejaculation. The recommended starting dose of dapoxetine is 30 mg.
- Tadalafil and dapoxetine are usually taken 30-60 minutes before sex.
- The combination can be used on demand or as prescribed by a doctor.
- Patients should report any prolonged erections or severe side effects immediately.
- The medication should not be used with nitrates or certain blood pressure medicines.
- Pregnant or breastfeeding women should avoid using these tablets.
- Proper storage away from moisture and heat preserves drug efficacy.
Depending on the patient's reaction and potential adverse effects, the dose might increase to dapoxetine 60 mg. It's taken orally, usually 1 to 3 hours before anticipated sexual activity.

One must be careful when it comes to combining dapoxetine with other medicines. Dapoxetine and certain recreational drugs, tricyclic antidepressants, or other selective serotonin reuptake inhibitors can interact. Consultation with a healthcare professional is crucial before initiating therapy with multiple drugs. Yes, dapoxetine can be taken alongside erectile dysfunction treatments such as sildenafil (Viagra).

Its maximum plasma concentration (Cmax) is reached one to two hours after oral administration. The Cmax and AUC (area under the plasma vs. time curve) is dose dependent. The Cmax and Tm (time needed to obtain the maximum plasma concentration) after single doses of dapoxetine 30 mg and 60 mg are 297 and 498 ng/ml at 1.01 and 1.27 hours, respectively. A high-fat meal does reduce the Cmax slightly, but it is insignificant.
Common Side Effects
It can be taken with or without food. Dapoxetine is absorbed and distributed rapidly in the body. The mean steady-state volume is 162 L. Its initial half-life is 1.31 hours (30 mg dose) and 1.42 hours (60 mg dose), and its terminal half life is 18.7 hours (30 mg dose) and 21.9 hours (60 mg dose). Dapoxetine is metabolized extensively in the liver and kidney by multiple enzymes such as CYP2D6, CYP3A4, and flavin monooxygenase 1.
Cardiovascular safety
The major product at the end of the metabolic pathway is circulating dapoxetine N-oxide, which is a weak SSRI and contributes no clinical effect. The metabolites of dapoxetine are eliminated rapidly in the urine with a terminal half-life of 18.7 and 21.9 hours for a single dose of 30 mg and 60 mg, respectively. The cardiovascular safety profile of dapoxetine has been studied extensively during the drug development. Phase I trials showed that dapoxetine had neither clinically significant electrocardiographic effects nor delayed repolarization effects, with dosing up to four-fold greater than the maximum recommended dosage, which is 60 mg. Phase III studies in men with PE showed a safety and well tolerated profile of dapoxetine with dosing of 30 and 60 mg. However, it's vital to be cautious of potential blood pressure fluctuations, as both medications can influence blood pressure. Common adverse reactions include dizziness, headaches, and nausea.
| Drug Category | Interaction Effect | Example Drugs |
|---|---|---|
| Nitrates | Risk of severe hypotension | Nitroglycerin |
| CYP3A4 Inhibitors | Increased plasma levels | Ketoconazole, Ritonavir |
| Other SSRI/SNRI | Increased side effects or serotonergic syndrome | Sertraline, Paroxetine |
To lower these effects, it's advised to: Avoid alcohol, as it can increase specific side effects.
- Common side effects include lightheadedness, nasal congestion, or stomach upset.
- Serious side effects, though rare, include vision changes or allergic reactions.
- Do not use if you have a history of severe hypotension or stroke.
- Alcohol consumption may impair the effectiveness and increase side effects.
- Use this medication only under medical supervision and guidance.
- Always read the patient leaflet for detailed instructions and warnings.
Be cautious when standing up from sitting or lying to prevent dizziness. Grapefruit juice is one of the drinks that might increase the level of dapoxetine in the blood, heightening the risk of side effects.
| Condition | Symptoms Addressed | Recommended Dosage |
|---|---|---|
| Erectile Dysfunction | Inability to maintain erection | 10 mg before sexual activity |
| Premature Ejaculation | Early ejaculation during intercourse | 60 mg before sexual activity |
| Combined Sexual Dysfunction | Erectile and ejaculatory issues | As prescribed by doctor |
Men with significant ischemic heart disease, sick sinus syndrome, a history of mania or severe depression (major depressive disorder), if already on tricyclic antidepressants, or those with severe renal impairment should avoid taking Priligy. Adverse effects associated with dapoxetine range from nausea, dizziness, and headaches to increased blood pressure. While most of these adverse reactions are mild, it's essential to recognize and report any severe adverse reactions immediately. Clinical trials have not conclusively linked dapoxetine to alterations in testosterone levels. However, always consult with a specialist in sexual medicine for comprehensive insights.
Shipping Information
No cardiovascular adverse had been found. Studies of SSRIs in patients with major psychiatric disorders prove that SSRIs are potentially associated with certain neurocognitive adverse effects such as anxiety, akathisia, hypomania, changes in mood, or suicidal thought. [30][31] No study on the effects of SSRIs in men with PE has been done. McMahon's study in 2012 showed that dapoxetine has no effect on mood and is not associated with anxiety or suicidality. The incidence of antidepressant discontinuation syndrome symptoms in men using dapoxetine to treat PE has been described by reviewers as low or no different from the incidence of such symptoms in men withdrawn from placebo treatment.
Does tadalafil interact with foods or drinks?
[33][34] The lack of chronic serotonergic stimulation with on-demand dapoxetine minimizes the potentiation action of serotonin at synaptic cleft, thus decreasing the risk of discontinuation symptoms. Currently, very few methods are used to synthesize (S)-dapoxetine. This novel approach consists of only six steps in which three main steps are shown above. The initial reactant is trans-cinnamyl alcohol, which is commercially available. Sharpless asymmetric epoxidation and Mitsunobu reaction have been used to produce expected (S)-dapoxetine.
Does tadalafil interact with other medicines (drug interactions)?
This method is considered a good choice compared to the known methods due to high yield and easily obtainable reactants. Dapoxetine was created by Eli Lilly and in phase I clinical trial as an antidepressant. It never worked out well as a medication for the treatment of depression, though, and was shelved for a while before subsequently developed to treat PE. In December 2003, Eli Lilly sold the patent for dapoxetine to Pharmaceutical Product Development (PPD) for US$65 million. Eli Lilly may also receive royalties payment tadalafil with dapoxetine online from PPD if the sale exceeds a certain amount. Dapoxetine, under the brand name Priligy, has been patented in the UK, allowing only certain distributors access. However, more affordable generics are expected to surface post-patent expiry (2024), providing a more cost-effective solution.
