Used to treat erectile dysfunction (ED) in men, Viagra works by helping to relax the blood vessels in the penis which then allows the blood to flow into the penis causing a hard erection that lasts the whole time you are having sex. Erectile dysfunction is when a man has difficulty getting an erection or keeping the erection long enough for sex. It is caused by not receiving enough blood flows to the penis, therefore, preventing an erection.

Erectile dysfunction affects about 30 million men in the United States. You have some men with ED that find it difficult to either get or keep an erection every single time they try to have sex with their partner. Then, you have others that only have symptoms that happen just every once in a while. Regardless whether it happens only from time to time or every single time, just know that you are not alone in this, Viagra is here to help. Viagra is not something that you have to take everyday. The only time you have to take it is when you need it. It only works when you are sexually stimulated and will not work otherwise. Usually, it starts to work for you within 30 to 60 minutes of taking the medication. If you do need the help of Viagra then you can take it up to 4 hours before your sexual activity takes place which allows you to take your time and not have to rush. Once you are finished having sex your erection should go away with no issues. If for some reason, which is very rare, you have an erection that will not go away and is lasting more than 4 hours then you need to seek immediate help to avoid a long term injury. Viagra is not right for everyone so make sure to always consult with your doctor first as your doctor is the only one that can decide whether or not it is right for you. Viagra should not ever be taken more than once in a twenty-four hour period and it should absolutely never be taken with any other type of erectile dysfunction medication.
