Sildenafil is a medication that is commonly prescribed to men who suffer from erectile dysfunction. This medication is also known by the brand name Viagra. Sildenafil works by increasing blood flow to the penis, which can help men achieve and maintain an erection during sexual activity. In this article, we will discuss what sildenafil does to a man and how it works.
How does sildenafil work?
Sildenafil works by blocking the enzyme phosphodiesterase type 5 (PDE5). This enzyme is responsible for breaking down a chemical in the body called cyclic guanosine monophosphate (cGMP), which helps to relax the blood vessels in the penis and increase blood flow. By blocking PDE5, sildenafil allows cGMP to accumulate in the penis, which can lead to an erection.
What does sildenafil do to a man?
Sildenafil can have several effects on a man's body. The primary effect is that it can help men achieve and maintain an erection during sexual activity. This can be especially helpful for men who have difficulty achieving an erection or who have trouble maintaining an erection long enough to complete sexual activity.
Sildenafil can also have other effects on a man's body, including:
Increased blood flow: Sildenafil can help increase blood flow to other parts of the body, which can be beneficial for men with conditions such as pulmonary arterial hypertension.
Improved exercise tolerance: Sildenafil can improve exercise tolerance in men with pulmonary arterial hypertension and other conditions that affect the heart and lungs.
Improved quality of life: For men with erectile dysfunction, sildenafil can improve their quality of life by reducing anxiety and improving their self-esteem.
It is important to note that sildenafil does not increase sexual desire or libido. It only helps to improve blood flow to the penis, which can help men achieve and maintain an erection during sexual activity.
How is sildenafil taken?
Sildenafil is typically taken as a tablet, either on an empty stomach or after a light meal. It is recommended that the medication be taken about 30 minutes to 1 hour before sexual activity. The effects of sildenafil can last for up to 4 hours, but the medication should not be taken more than once a day.
Are there any side effects of sildenafil?
Like all medications, sildenafil can cause side effects. Some of the most common side effects of sildenafil include headaches, facial flushing, indigestion, and nasal congestion. These side effects are usually mild and go away on their own. However, if you experience any severe or persistent side effects, you should contact your healthcare provider right away.
In rare cases, sildenafil can cause more serious side effects, such as sudden vision loss or hearing loss. If you experience any sudden changes in vision or hearing while taking sildenafil, you should stop taking the medication and seek medical attention immediately.
