Viagra (sildenafil) is a medication used to treat erectile dysfunction (ED) in men. It works by increasing blood flow to the penis, which helps to produce and maintain an erection.
Benefits of Viagra
The primary benefit of Viagra is its ability to improve erectile function in men with ED. It can also help to improve sexual satisfaction and confidence. In addition, it has been found to be effective in treating pulmonary arterial hypertension, a type of high blood pressure that affects the lungs.
Dosage Instructions
The recommended dose of Viagra is typically 50 mg, taken prior to sexual activity. The dose can be increased to 100 mg or decreased to 25 mg, depending on individual response and tolerability. Viagra should not be taken more than once per day. It is important to follow the dosage instructions provided by a healthcare provider.
Side Effects
Viagra can cause some side effects, which may include headache, facial flushing, indigestion, and nasal congestion. Rare but serious side effects can include sudden vision loss, hearing loss, and an erection that lasts longer than four hours (priapism). Men with a history of heart disease or stroke should discuss the risks and benefits of Viagra with their healthcare provider before starting treatment.
Half-life
The half-life of Viagra is approximately four hours. This means that it takes this amount of time for half of the drug to be eliminated from the body. As a result, it is typically taken 30 minutes to four hours before sexual activity.
In conclusion, Viagra is an effective treatment for ED in men and can also help to improve sexual satisfaction and confidence. It is important to follow the dosage instructions provided by a healthcare provider and be aware of the potential side effects. Men with a history of heart disease or stroke should discuss the risks and benefits of Viagra with their healthcare provider before starting treatment.
