Viagra is a brand name associated with the medication Sildenafil used to treat Erectile Dysfunction. Erectile Dysfunction is the inability for a man to have and maintain an erection usually due to problems with blood vessels or nerves surrounding the penis. Viagra helps to treat Erectile Dysfunction by relaxing blood vessels in the penis, allowing blood to come in, creating an erection. More specifically, Sildenafil works by inhibiting an enzyme that degrades the nucleotide cGMP, which regulates blood flow in the penis. Erections can then be had and maintained for a four hour period after taking Viagra, although not necessarily lasting four hours straight.
Viagra should be stored below 30 degrees Celsius and holds a lifetime of 5 years. Visually, Viagra is a blue rounded diamond, film coated, with “VGR 50” and “Pfizer” engraved on its sides.
Originally, Sildenafil was used as a treatment for cardiovascular disorders, as synthesized by chemists David Brown, Andrew Bell, and Nicholas Terrett in a research facility based in England for Pfizer, before its use to limit Erectile Dysfunction was discovered. After this discovery, the drug was remarketed for this use, and entered the market in 1998, becoming the first oral treatment approved by the FDA to treat Erectile Dysfunction.
One in ten patients are estimated to experience side effects from taking Viagra. Side effects of taking Viagra include headaches, flushed skins, indigestion, and abnormal vision. Pain in the back and muscles, as well as dizziness and nausea, can also occur. In rare cases, Viagra can cause painful erections which won’t go away, and if that happens, one should contact a health professional immediately and seek medical attention, as this can lead to penis damage and hearing loss. If one has ever had a stroke or heart disease, it is suggested that one does not take Viagra. Lastly, blood pressure medications and other nitrates can react with Viagra, so use with these medications should be avoided also.
Throughout the world, Viagra is usually only available through prescription. In Australia, the drug holds an S4 Classification, specifying that the drug is only available through prescription. However, Viagra can be purchased online without a prescription from many sites, although the legitimacy of the pills and their safety when bought online is compromised. Therefore, it is suggested that one only buy Viagra from reputable establishments.
Dosage
Viagra bought from reputable establishments comes packaged with four tablets. These packages are available in three separate doses: 25, 50, and 100 milligrams. However, cost is the same regardless of dosage to patients, at $6.20 per packet.

In Australia, Viagra is subsidized, which lowers the cost to customers, with the government paying between $50 and $80 depending on the brand purchased.
Many generic versions of Viagra are available online on websites such as Viagramelbourne (viagramelbourne.com) for as low as AUD $2.14. Shipment to Australia takes 1-2 weeks.However, as previously mentioned, Viagra is one of the most counterfeited medications in the world and any medication bought online should be heavily scrutinised.
