Product Safety Information for Dapoxetine (Priligy)

Dapoxetine – Important Safety Information

What Priligy is and what it is used for

Priligy contains an active substance called ‘dapoxetine’. This belongs to a group of medicines called ‘selective serotonin reuptake inhibitors’ (SSRIs). Priligy may also be known as a ‘urological’ medicine. 

Priligy increases the time it takes to ejaculate and can improve the control over the ejaculation. This may reduce the frustration or worry about fast ejaculation. 

Priligy is used to treat premature ejaculation in adult men aged 18 to 64 years. 

Premature ejaculation is when a man ejaculates with little sexual stimulation and before the man wants. This can cause problems for the man and may cause problems in sexual relationships.
