Tadapox 80 mg is a combination drug which includes Tadalafil and Dapoxetine as its major constituents. Tadalafil is a PDE5 inhibitor and is used to treat erectile dysfunction, while Dapoxetine is a SSRI and is used in treating premature ejaculation. This medication is prescribed for the treatment of both ED and PE among males. ED is termed as the inability to achieve or maintain an erection that is adequate for satisfactory sensual activity, or the inability to maintain an adequate erection until completion of sensual activity. PE is defined as a persistent or recurrent pattern of ejaculation, which occurs immediately before or following beginning of sensual activity. Tadalafil is known to act by promoting blood flow to the male genital organ, hence facilitating the accomplishment of an erection as well as its sustenance. Dapoxetine acts by raising the level of serotonin within the brain. Tadapox 80 mg is to be orally taken, along with or without food, as required, 30 minutes before sensual activity. This does not protect against sensually transmitted diseases like HIV, Syphilis, and Gonorrhea. Common side effects of the drug are headache, flushing, indigestion, dizziness, blurred vision, and nasal congestion.
