Viagra- How Long Does It Last? When Does It Start To Work?

What is Viagra?

Viagra is a medication that is used to treat erectile dysfunction or commonly known as impotence in men. It generally relaxes the muscles found in the walls of your blood vessels which increases the blood flow to some specific areas of the body.

Is Viagra Dangerous?

Many medications can cause dangerous effects when used as a combination with Viagra. Before taking Viagra make sure you speak with your doctor about any other medications that you might be taking.

• If you have been told you should not have sexual intercourse for health reasons.

How should I take Viagra?

You should take Viagra exactly in the way it is prescribed to you. Unlike other medicines, Viagra is supposed to be taken only when it is needed which typically means 30 minutes or 1 hour before any sexual activity. It shouldn’t be taken more than once a day. Post taking the pill, an erection will only occur if sexual stimulation takes place and not just by taking Viagra. If during any sexual activity you face dizziness, nausea, pain, numbness or any kind of tingling in your arms, neck, chest or jaw, then you should immediately stop and seek medical attention. Make sure you store at room temperature and away from any moisture or heat.

What happens if I miss a dose of Viagra?

How long does Viagra last and how soon does it work?

It generally takes about 30 minutes to 1 hour for the pill to start working and the effects of the medication lasts up to 4 hours. The higher the dose, the increased duration of hardness and duration of erections. Viagra is taken orally and absorbed by your stomach. If you take Viagra after a fatty meal then it may take longer to work as fat in the food slows down the absorption in your stomach. If you are over the age of 65 and have liver or kidney disease then the effects of Viagra may stay on for longer and this is why the dose might need to be reduced. 

Viagra works by increasing smooth muscle relaxation in the part of the penis so when stimulation of the penis takes place, a hormone is released and this increases the blood to your penis. Since this hormone is only released when the penis is stimulated, Viagra will not give you an erection without there being any sexual stimulation of the penis. Viagra only makes your penis erect but does not necessarily make you last longer, so if you have premature ejaculation then that may not be treated by Viagra.

Erectile dysfunction has many causes. Viagra is not a cure. It does not increase your desire for sex. The most common cause of erectile dysfunction is decreased blood supply to the penis, which may be a warning of decreased blood supply to other parts of your body. Your doctor may check you for high blood pressure, heart disease and type 2 diabetes. Erectile dysfunction can also be caused by depression, anxiety and drug or alcohol abuse. Your doctor may help you manage these problems before or in addition to prescribing Viagra.
