Sildenafil is marketed under the brand name Viagra. Sildenafil treats erectile dysfunction by increasing blood flow to the penis during sexual stimulation.
Sildenafil is a medication used to treat erectile dysfunction (ED) and pulmonary arterial hypertension (PAH). It belongs to a class of medications called phosphodiesterase-5 (PDE-5) inhibitors, which work by relaxing the muscles in the blood vessels and increasing blood flow to the penis or lungs.
The benefits of sildenafil include its ability to improve erectile function in men with ED and to improve exercise capacity and quality of life in people with PAH. It is generally well tolerated, with few side effects. However, some people may experience side effects such as headache, flushing, upset stomach, or vision changes.
It is important to note that sildenafil should not be taken by people who are allergic to it or any of its ingredients. It may also interact with other medications, so it is important to inform your healthcare provider about all the medications you are taking before starting treatment with sildenafil.
Sildenafil is usually taken as a tablet, usually once a day as needed. It is usually taken about an hour before sexual activity, although it can be taken anytime from 4 hours to 30 minutes before sexual activity. It is important to follow your healthcare provider's instructions for taking sildenafil and to not take more than the recommended dose.
Overall, sildenafil is an effective treatment for ED and PAH, and can help to improve sexual function and exercise capacity. However, it is important to follow your healthcare provider's instructions and to report any side effects that you experience. Do not take sildenafil without first consulting your healthcare provider.
