These drugs are often used to treat similar conditions. Sildenafil works in different ways, depending on the condition it’s being used to treat. For ED: Sildenafil works by increasing blood flow to the penis. This helps you get or maintain an erection. Sildenafil only works for ED if you’re sexually aroused. For PAH: Sildenafil works by relaxing the muscles and opening up the blood vessels in your lungs. This decreases the blood pressure in your lungs. Sildenafil slows down the progression of your illness. It also makes you more able to exercise. Sildenafil can be used as early as 4 hours before sex and as late as 30 minutes before sex. However, it is recommended to use this drug within an hour before sex. Sildenafil should not be taken for ED more than once in a 24-hour period.
