What Is Viagra: A Simple Explanation
Viagra is a medication used to treat erectile dysfunction in men. Erectile dysfunction means having trouble getting or keeping an erection during sexual activity. Viagra helps by improving blood flow to the penis, making it easier to achieve and maintain an erection.
The active ingredient in Viagra is called sildenafil citrate. It works by relaxing the blood vessels in the penis, allowing more blood to flow in when a man is sexually stimulated. Viagra does not cause an erection on its own; sexual arousal is still needed.
Viagra is taken as a pill, usually about 30 minutes to one hour before sexual activity. Its effects can last for about four to six hours. The medication should be taken only as directed by a doctor and not more than once a day.
Viagra is a prescription medicine, so it is important to consult a healthcare provider before using it. Some people should not take Viagra, especially those with certain heart conditions or who take medicines called nitrates. More Details how long does viagra last
