100mgKamagra, or sildenafil citrate, is a generic form of the drug Viagra. It is prescribed to men for erectile dysfunction, or ED. While it will not increase your sex drive, and it cannot make you aroused if you aren’t, it can help you to achieve an erection if you are sexually aroused. It can be taken in tablet form. Most men are given fifty milligram tablets, but your doctor will help you determine whether you need a higher dose.
