The medication kamagra is used to treat erectile dysfunction in men. This is an alternative to Viagra (sildenafil citrate), a medication used to treat erectile dysfunction in men. Kamagra works by increasing blood flow to the penis. Congestion in the nasal passages, headache, diarrhoea, nausea, and vomiting are all possible side effects. An unwanted side effect like blushing may be less evident in Viagra users. Kamagra has been linked to the extremely rare but life-threatening condition known as priapism, or a prolonged erection. Call your doctor if you have an erection that lasts more than a few hours. View more here: Cheaptrustedpharmacy
