Viagra is a brand name for the drug Sildenafil Citrate and it is used to treat erectile dysfunction mainly in men. The drug has a positive effect on at least two thirds of men who use it. The drug is mainly taken in pill form but it can also be injected or taken orally in gel form. In most countries including Australia, Viagra is a prescription drug and as such advice should be taken from your doctor in regards to its safety. In the UK and New Zealand Viagra can be bought from pharmacies over the counter without a prescription but in Australia the drug is still only prescribed by a doctor. This is because the Medicines and Healthcare products Regulatory Agency in Australia has decided that due to the potential for cardiovascular problems associated with Viagra use, men must be older than eighteen years old and have a screening from a pharmacist. It is also important to check for any history of liver or kidney failure, as these problems can be magnified with the use of Viagra. In Australia it is however possible to order Viagra online and import it from abroad.
Users should make sure to carefully check the proper dose. One Viagra pill often ranges from 50mg to 100mg and is usually considered one dose. Overdose can cause serious health problems and must be taken seriously. Taking too much Viagra can result in a disproportionately large and long lasting erection that may permanently damage the penile tissue. It can also lead to future erections being painful. Because of these associated problems doctors recommend taking only one Viagra pill per day at maximum.
Viagra works by leading to smooth muscle relaxation and increasing blood flow and takes twenty minutes to take effect and lasts for roughly two hours. The drug is commonly taken four hours before sex. There are some side effects associated with Viagra that one should be aware of. In clinical trials users often report flushing, headaches, indigestion, nasal congestion, blurred vision and impaired vision. There have also been reports of userâs vision being altered and tinted blue along with hearing loss.
Viagra was discovered in 1989 and manufactured by Pfizer in India. It can sometimes be considered expensive depending on the market and this has given rise to many other brand names and cheaper versions of the medicine in its different forms. Viagra use has increased across the western world and it now has millions of users worldwide. Viagra has also become more commonly used recreationally, as it is widely believed that the drug increases libido and sexual prowess. Recreational Viagra has also become mixed with recreational drugs such as ecstasy, this is an incredibly dangerous mixture that should be avoided at all costs. Viagra should also not be taken if you are currently taking medicines known as nitrates for chest pains, if you have recently has a heart or liver problem, or have had a stroke in the recent future. It is also a good idea to avoid Viagra low blood pressure.
