Dapoxetine safety summary

Prescribed for men aged 18 to 64 with premature ejaculation. Taken 1 to 3 hours before sexual activity.

• The starting dose is 30 mg on demand; treatment is never started at 60 mg.
• Never take more than one dose in any 24-hour period, and only when you plan to have sex.
• Swallow the tablet whole with at least a full glass of water — this lowers the risk of fainting.
• Your doctor reassesses whether to continue after the first four weeks or six doses, and at least every six months.

Uncommon, but they need immediate medical attention.

• Fainting (syncope), usually within three hours of a dose and often after the first dose.
• Warning signs before fainting: nausea, dizziness on standing, light-headedness, palpitations, sweating or confusion — lie down at once with your head lower than the rest of your body.
• A slow heartbeat, or a pause in the heartbeat, associated with fainting.
• New or worsening low mood, agitation, or thoughts of harming yourself.
• Severe allergic reaction (rash, swelling of the face or throat, difficulty breathing).
• A seizure, or a faint that causes a fall or head injury — call emergency services.
