Viagra (sildenafil), widely recognized as the erectile dysfunction (ED) drug, was originally created to treat high blood pressure and heart disease. Interestingly, during clinical trials it was found to increase penile erections, while having little impact on treating heart disease. After that discovery, Viagra was marketed as a drug to treat erectile dysfunction and was approved for use by the FDA in 1998.
Erectile dysfunction (ED) affects 52 percent of men between the ages of 40 and 70. Experts say however, that up to 70 percent of men are too ashamed to seek advice from a medical professional, and therefore live with ED instead of treating it, and enjoying a healthy sex life. The most common causes of ED are decreased blood flow, and nerve stimulation. As men age, arteries become narrowed causing decreased blood flow to the penis. ED is not a psychological problem, but a physiological one. And because it is physiological, it can be helped with medication.
Viagra is a prescription medication used to treat erectile dysfunction (ED). By relaxing the smooth muscles (vasodilation) in the walls of the arteries, Viagra increases blood flow into the penis, allowing men to achieve and maintain an erection. It is important to note that sexual stimulation is still necessary to achieve an erection. Viagra simply helps the body to achieve ‘normal’ arousal by temporarily increasing blood flow to that region.
Viagra is a #1 drug against erectile dysfunction
Although many drugs that combat erectile dysfunction are on the market, Viagra remains the most effective for its prevention.
Viagra, and the generic version sildenafil, are available through a wide array of internet sources. There are many websites that sell Viagra and frequently do not require a prescription. However, users of these services should be weary – it is often difficult to discern whether these pills do indeed contain the drug. Therefore, it is safest to buy Viagra, and all other medications for that matter, from store-based or reputable online pharmacies. Due to the sheer number of pills sold each year, Australia and the EU are currently considering making Viagra, and other ED treatment drugs, available over-the-counter. Currently however, a prescription is still required to buy Viagra, and to ensure that patients are buying authentic, pills.
Viagra in online pharmacy
Many online pharmacies sell Viagra, and the generic version sildenafil, in Australia. It comes in 25 milligram (mg), 50 mg, and 100 mg doses. The recommended dose for ED is 50mg, taken orally, about 1 hour before sexual activity. However, evidence suggests that Viagra is still effective if taken anywhere from 30 minutes to four hours before sexual intimacy. Viagra comes in a blister pack and should be stored below 30 degrees Celsius. The lifetime of the pack is 5 years.
If you are thinking about incorporating Viagra into your sex life, you should discuss it with your doctor. It may not be safe for men with certain medical conditions including men who have recently had a stroke, have heart disease or retinitis pigmentosa (an inherited eye disease). The most common temporary side effects of Viagra include: headache, visual disturbance (blurred vision, light sensitivity, color perception change), flushing (to become markedly red in the face and other areas of the skin), and dyspepsia (stomach discomfort including bloating, nausea, heartburn, etc.). If any sudden extreme changes in health occur after taking Viagra, emergency medical care should be sought out immediately.
