Frequently asked questions

Is dapoxetine an antidepressant?

It belongs to the same family (SSRI) but acts quickly and briefly, so it is used before sex rather than for depression.

Why can it cause fainting?

It can lower blood pressure briefly. Taking it with a full glass of water and avoiding alcohol reduces the risk.

Can I take it every day?

No. It is designed to be taken only before planned sexual activity, as directed by your doctor.
