Viagra 50mg is a medication used to treat erectile dysfunction (ED) in men. It contains sildenafil citrate, a phosphodiesterase type 5 (PDE5) inhibitor that helps to increase blood flow to the penis, enabling a man to achieve and maintain an erection.
The recommended starting dose of Viagra is 50mg, which can be taken about an hour before sexual activity. The maximum recommended dose is 100mg per day, and the effectiveness of the medication can last for up to four hours.
It is important to note that Viagra does not work without sexual stimulation. It also does not increase sexual desire or libido.
