Introduction

Viagra (Sildenafil) is a prescription medication used to treat erectile dysfunction (ED) in men. ED is a condition in which a man is unable to achieve or maintain an erection sufficient for sexual intercourse.

How it works

Viagra works by increasing blood flow to the penis, which helps to achieve and maintain an erection. It does this by blocking the action of an enzyme called phosphodiesterase type 5 (PDE5), which can reduce blood flow to the penis.

Dosage and Administration

Viagra is available in tablet form and should be taken orally, typically 30 minutes before sexual activity. It can be taken with or without food, but it is best to avoid a high-fat meal as it may slow down the absorption of the medication. The effects of Viagra typically last for 4 hours.

Precautions

Viagra does not cure ED or increase sexual desire. It should be used under the supervision of a doctor and only used as needed. Before taking Viagra, it is essential to talk to a doctor, especially if you have a history of heart disease, low or high blood pressure, liver or kidney disease, or vision problems. The use of Viagra may also interact with other medications, so it is important to provide your doctor with a complete list of all the medications you are taking.

Side Effects

Possible side effects of Viagra include headache, flushing, indigestion, and upset stomach. More serious side effects are rare but may include changes in vision or hearing, chest pain, or an erection that lasts longer than 4 hours (which requires medical attention).

Conclusion

Viagra is a prescription medication used to treat ED by increasing blood flow to the penis. It is important to talk to a doctor before taking Viagra to ensure its safe and effective use.
