Its funny. a lot of people don’t really know where Viagra comes from and how it originally came into existence. In a simple sense, Viagra is a man made substance made for erectile dysfunctions for men. It’s main function is that it relaxes muscles found in the walls of blood vessels and increases blood flow to particular areas of the body. It’s actually a funny story how this drug got its origin from because it was a scientific breakthrough that resulted in a happy accident. Pfizer an American global pharmaceutical corporation started a new research in Late March 1998 hoping to find a something that might lower hypertension. That something they were working with at that moment was sildenafil citrate, and they used this product on over 4k + male subjects.
It was said that between all of the subjects about 80% of them gained an erection. They wasted no time after the discovery because it fast-tracked through the approval process by the Food and Drug Administration.
Viagra is the most popular and the longest established erectile dysfunction medications in the world. Its use is now one of the standard treatment for erectile dysfunction, including for men with diabetes mellitus. All erectile dysfunction medications work relatively similarly – they are PDE5 inhibitors. Viagra was found effective for sustaining erection in 60 percent to 80 percent of the patients – and more than 30,000 patients have attested to its ability to do so.
For erectile dysfunction, the medication will help achieve an erection when sexual stimulation occurs. It works by increasing blood flow to the penis by relaxing the smooth muscles in the prostate and bladder. Viagra has been used for nearly 25 years, and is expected to be a relatively safe medication.
However, as with all medications – Viagra does not come without side effects and negative aspects. The most common side effects are headaches, stomach discomfort or pain, indigestion, acid reflux, back and muscle aches, and flushing.
Do not take Viagra if you have chest pains or heart problems, a recent heart attack, a stroke or congestive heart failure, a bleeding disorder, chest pain, high or low blood pressure, liver or kidney disease, ulcers, eye conditions or physical deformities in your penis. If you have had any of these conditions in the past, you should see a physician before taking any erectile dysfunction medication. Before taking Viagra, you should advise your physician or pharmacist if you are allergic to it.
If you become dizzy or nauseated, have pain or numbness, or any tingling or pain, please stop what you are doing and contact your physician immediately. There is a small chance that you may also have an erection for more than 4 hours after taking Viagra – if this occurs, please call your physician or medical help right away.
To avoid side effects, do not consume alcohol or grapefruit juice while taking this medication.
While it is not expected that Viagra would have harmful effects on pregnant women or unborn children, it is highly advised that women and children do not handle or ingest Viagra.
Viagra should be taken no more than once per day, and you should follow your prescription instructions on the label – do not take more or less than is recommended. It can be taken with or without food, but should be swallowed hole.
The medication does not protect against sexually transmitted diseases – such as HIV, hepatitis B, gonorrhea or syphilis – and you should always use a condom.
Because Viagra is used for erectile dysfunction, it is not normally prescribed on a daily basis, and it is unlikely that you will need to take the medication if you miss a dose.
Viagra can be purchased online, especially in Australia, via a number of online pharmacies. The pills range in cost depending on the dosing amount and how many pills are purchased – which also include doses of 25 mg, 50 mg and 100 mg. The medication is one of the more expensive – but also had been proven to be one of the most effective medications – and costs between $20 and $40 per pill. There are generic versions of the pill available for between $1 and $5 per pill.
