Side Effects Of Sildenafil 20 Mg

Description

Sildenafil is a prescription medication used to treat erectile dysfunction (ED). Sildenafil is also used to treat adults with pulmonary arterial hypertension (PAH).Sildenafil belongs to a group of drugs called PDE inhibitors. Sildenafil treats ED by increasing blood flow to the penis during sexual stimulation, which leads to an erection. Sildenafil treats PAH by relaxing the blood vessels in the lungs to allow blood to flow easily.This medication comes in tablet form and is taken one hour before sexual activity if treating for ED. It is taken 3 times a day, 4-6 hours apart, if treating for PAH.This medication also comes as an oral suspension (liquid) and in an injectable form to be given directly into a vein (IV) by a healthcare professional.
