Viagra is a brand name prescription drug used for the treatment of erectile dysfunction. The drug functions by limiting chemical reactions that take place in the body, essentially allowing more blood to flow through the penis. This leads to a longer lasting, fuller erection in men. Interestingly, Sildenafil Citrate, known by the brand name “Viagra”, was initially studied as a possible drug that could treat hypertension, otherwise known as high blood pressure. In fact Sildenafil is used in higher doses, as a treatment for hypertension to this day. Outside of those two prescription uses, the drug has been also been studied as a possible preventative medication for high altitude sickness, although this is considered off label use as it hasn’t been studied in enough detail.
As with most medications there are possible side effects. Indigestion, flushing of the hands and chest, and nasal congestion are all possible side effects. In rare cases there can be some more serious adverse side effects such as, possible heart attack, severe low blood pressure, and possible hearing and/or vision loss – although these complications are relatively rare and millions of men a year use the drug successfully. As with all erectile dysfunction medication if you have an erection last longer than 4 hours you should seek immediate medical attention.
It is important to note that Viagra is a prescription drug, and as such you should make an appointment to speak with a physician to make sure it is safe for you to take it, and that it will not interact negatively with any possible medications you are on. Those who take nitrates for other conditions should not take Viagra due to the conflicting nature between the drugs. Nevertheless, as long as you are medically cleared to use Viagra it is a drug used by millions of men a year relatively safely to help improve their sex lives. This can be especially useful for those who are experiencing sexual dysfunction because they are taking certain antidepressants(which are known to cause possible impotence).
When using Viagra, the effects may vary from person to person, but generally speaking you should take the pill roughly 30-45 minutes before you expect to make use of the effects. When Viagra is used along with sexual stimulation the effects of the pill can last anywhere from 2 to 5 hours before the effects naturally wear off as the body metabolizes the drug. The average duration experienced before users noticed the the effects of the pill started wearing off is between two to three hours. Among other things affecting the duration are age, alcohol consumption, and dosage.
