Dapoxetine was specifically developed in 2003 for the treatment of premature ejaculation. It has proven highly effective for the treatment of early ejaculation and is widely used throughout the world for this purpose. The recommended dosage is one tablet with a glass of water one and a half hours prior to sexual activity. Do not take more than one tablet in any 24 hour period. The tablet should be swallowed whole and not chewed. You might experience mild side effects which will not last.
