You have probably heard or seen many advertisements proclaiming the wonders of the small blue pill called Viagra. This drug has been available to the public since 1998 by the pharmaceutical company, Pfizer. Viagra is used to treat a very common medical condition called erectile dysfunction. This affects men’s ability to achieve or sustain an erection during lovemaking. Viagra works by blocking an enzyme that interferes with men’s ability to achieve an erection. It increases blood flow to the penis and relaxes the muscles in the penile region. Viagra only works in combination with sexual stimulation, and it should be taken approximately 30 minutes to one hour before engaging in sexual intercourse. It is available as oral pills in 25mg, 50mg and 100mg doses, and can work in as little as 15 minutes after taking it. Most men report that the drug lasts approximately 3 to 4 hours, although some men enjoy results for up to 5 hours. So if you’re suffering in silence from erectile dysfunction, be sure to try Viagra for yourself. You may be surprised at how quickly and effectively it works!
