How Viagra can be bought online

Viagra is a pharmaceutical with a very interesting history. Originally designed for treating Pulmonary hypertension, Viagra is the brand name of the generic drug Sildenafil. It was discovered and tested by a trio of Pfizer scientists working out of Kent England, with the first patent being filed in 1996. Viagra gained approval for commercial sale for erectile dysfunction in 1998 by the Food and Drug Association. Only allowed to be sold through prescription in the United States, the retail drug, Viagra, enjoyed great commercial success, reaching a peak of sales in 2008, with the patent expiring in 2020. In December of 2017, due to economic pressures of competing companies, Pfizer went ahead and released a generic version of the drug they invented.

Viagra and Sildenafil work by increasing smooth muscle relaxation which enhances the blood flow. This is important because a penis becomes erect when the arteries dilate and fill with blood. Viagra accomplishes this through the release of nitric oxide, which leads to vasodilation and increase blood to the spongy tissue of the penis. Viagra is further broken down by your liver through by hepatic metabolism. The time to reach maximum effectiveness is usually about one hour.

In Australia, Viagra can be bought in three different oral doses, 25mg, 50mg, and 100mg. It is advised to start with a lower strength dose and work your way up to the higher ones. Because no patents exist for Sildenafil in Australia, much cheaper generic versions of the same drug can be bought online, circumventing the need for a prescription, thus keeping the costs down as well. Delivery is fast and the shipping is discrete.

Viagra can be bought online, with delivery right to your door with many online vendors. Prices average about R46 (.50 US) per pill for the highest dose 100mg pills, but that cost decreases dramatically as you buy in higher quantities. You can get them for as little as R11 per pill if you buy in lots of 360 or higher. It is available in all the major cities across Australia, including Johannesburg and Cape Town.

It should be known that Viagra has several side effects for some users as well. Some of the more common side effects are dizziness, headaches, upset stomach, flushing, and diarrhea. More serious complications from an allergic reaction could be a heart attack, a stroke, loss of vision, irregular heartbeat, or even death. Viagra must not be taken with other medicines containing nitrates, or if the patient is allergic to Sildenafil. In very rare cases, the patient can even obtain an erection that won’t go away. This can be very dangerous and would need medical intervention before possible priapism could occur. Viagra and Sildenafil are meant to be taken once per day roughly one hour before sexual activity. The drug is taken orally and can be taken with food, although care should be taken to not dose Viagra with a fatty meal as it may impede the effects of the drug.

Viagra should be stored at around 25 degrees Celsius and kept away from direct light and moisture. Obviously, it is to be kept out of the reach of children and pets as well.
