Viagra is a medication that is used to treat Erectile dysfunction (ED), which is defined as the persistent inability to achieve and or maintain an erection. This affects an estimated 100 million men worldwide. Erectile dysfunction is assumed to be associated with advancing age but heart disease, obesity, high blood pressure, high cholesterol and many other physical ailments can cause ED. If you have experienced any of the following symptoms Viagra can be a viable option for you.
• Trouble getting an erection
• Trouble keeping an erection
• Reduced sexual desire

Viagra will relax the muscles found in the walls of blood vessels and increases blood flow to areas of the body. It improves the erectile response when a man is already sexually stimulated, but it does not provide sexual stimulation. If there is no sexual stimulation, Viagra will not work. Viagra usually starts to work within 30-60 minutes. You may take it up to 4 hours before sexual activity. This means that enough of the medication is still circulating in your blood stream in the event that you become sexually aroused. So there’s no need to rush. The dose can be adjusted as needed for effectiveness and tolerability. Viagra can be taken with or without food. However, if Viagra is taken with a high-fat meal, it will take longer for its effects to work. You mustn’t take Viagra more than once a day.
