The drug, taken one to three hours before sex, works by altering seratonin levels in the brain, which helps a man to have more control over his moment of climax.
Priligy has been shown to make men last three times as long.
However, it is expensive - at 76 pounds for a pack of three Priligy 30mg tablets.
Priligy, which is available for men aged 18 to 64, is already in the markets of some European countries. It will be sold exclusively online, for private prescriptions only.
The drug can't be used after boozing as this increases the risk of side effects.
Men will be able to get a private prescription for Priligy following an online consultation at Lloyds-pharmacy.com.
"Priligy has the potential to do as much for men's sexual health as Viagra," the Sun quoted Nitin Makadia, head of male sexual health at Lloyds-pharmacy, as saying.
"It will give sufferers a chance to improve the quality of their relationships and their general wellbeing.
"It has been well received by men elsewhere in Europe and we are really pleased to be bringing this treatment to the UK.
"Some men are understandably reluctant to discuss the problem with their GP so we are removing this barrier to treatment," Makadia added. (ANI)
