Dapoxetine

Dapoxetine is an SSRI, a selective serotonin reuptake inhibitor, the same family as sertraline and paroxetine. Doctors noticed long ago that daily SSRIs delay ejaculation as a side effect, and for years they treated premature ejaculation off-label that way, with all the daily-antidepressant baggage attached. Dapoxetine is the version built for on-demand use: it hits fast and most of it is gone by the next day, so you take it before sex rather than every morning for weeks. More serotonin along the reflex that fires ejaculation pushes the trigger point back. It does nothing for erections and nothing for desire. Americans mostly meet it online, in grey-market strips or combination tablets, since it never cleared the US.

It often arrives in the same tablet as sildenafil or tadalafil. That pairing makes sense when you have both problems, or when the fear of losing your erection is part of why you rush: the PDE5 handles hardness, dapoxetine handles timing. Two different problems, two drugs, one pill. If your erections are fine, the combo just adds PDE5 side effects for nothing.

Big, consistent phase 3 trials across thousands of men, the kind of base you want behind something you swallow. The size of the effect is the honest part:

Take 30 mg one to three hours before sex, with a full glass of water. Food is fine, and a light meal takes the edge off the nausea. Take your first dose at home on a night with no driving after, because the rare fainting episodes cluster around the first dose. If 30 mg buys you enough time, stay there: holding the low dose that works is winning, not underdosing, and nausea climbs hard at 60. Move to 60 only after a few honest tries at 30 fell short and your stomach handled it. One dose in 24 hours, and keep it on demand; running it daily adds side effects, not minutes.

Drinking is where dapoxetine bites, and the label says avoid alcohol on it for good reason: alcohol stacks the dizziness and the fainting risk, and a faint on the way to the bathroom is how people get hurt. Pick one per night, the pill or the drinks. Never combine it with other serotonin drugs, meaning an antidepressant, tramadol, St John’s wort or MDMA, and skip it if you’re on a strong antifungal like ketoconazole or an HIV booster, which push levels up. On a moderate CYP3A4 blocker like erythromycin, fluconazole or diltiazem, stay at 30 mg. And skip dapoxetine entirely if you have heart failure, serious heart disease, or a history of fainting; those are on the label’s do-not-use list.

If you’re buying a combination tablet, know that most pack the top dose of both drugs. Half a tablet is the better first try, and the PDE5 half brings its hard rule with it: never with nitrates. If you’d rather not swallow a serotonin drug at all, a lidocaine and prilocaine numbing spray applied before sex is the local alternative, and plenty of men do fine on it.

The serotonin side of the shelf, so the sides live in your gut and your head, mostly at 60 mg:
