Sildenafil (Viagra) helps treat Erectile dysfunction (impotence and inability to have or maintain an erection) in males. Sildenafil (Revatio) is used to enhance the ability to exercise for adults suffering from the condition of pulmonary arterial hypertension (PAH which is a condition that causes elevated blood pressure within the blood vessels that transport oxygen to the lung, which causes dizziness, breathlessness and fatigue). Children shouldn’t normally use sildenafil. However, in certain instances doctors may determine the sildenafil (Revatio) is the most effective medicine to treat the child’s illness. Sildenafil is part of a group of drugs known as PDE (PDE) inhibitors. Sildenafil helps treat erectile dysfunction by enhancing blood flow to the penis in the course of sexual stimulation. This increased blood flow could create an sexual erection. Sildenafil is a treatment for PAH by relaxing veins in the lung. This allows blood to flow freely.
If you’re using sildenafil to treat the problem of erectile dysfunction, be aware that it cannot treat erectile dysfunction, nor does it increase the desire to sexually. Sildenafil is not able to stop pregnancy, nor does it prevent the transmission of sexually transmitted infections like the human immunodeficiency Virus (HIV).
