(Note: Many of the drugs that say "Viagra" are actually generic Viagras, using the term, as it has now become, as a general word for ED treatment.) Studies are still in process in relation to the condition known as NAION (non-arteric anterior ischaemic optic neuropathy). So far very few cases have been linked between NAION and men taking PDE-5 Inhibitors such as Sildenafil Citrate (the active ingredient in Viagra), and studies have been inconclusive so far. Another word of caution for patients treated for HIV with Protease inhibitors. Ideally, they should no use Viagra, and if at all they do, it is best to limit the intake and/or consult a doctor. Viagra is also not recommended for people having nitroglycerin, as this may adversely impact and lower the blood pressure levels. This can then lead to people making use of generic Viagra when an examination would have shown that it was unfeasible. This can lead to a greater incidence of adverse side effects being felt by those people who take generic Viagra. This is not necessarily an indication of the effectiveness of the medication, but rather of the restrictions on buying generic [[http://withouatdoctor.us|viagra without prescription]]. This can be avoided by placing more stringent checks in place before allowing people to buy medication such as generic Viagra. Viagra rules the roost in most parties; it is considered a king among the party drugs and worshipped, with an ardent fan following. Yes, there is always a misconception that Viagra is a libido enhancer that every Tom, Dick and Harry can use to polish their sexual image. Many guys regale in the myth that Viagra helps in averting pregnancies and fighting sexually transmitted diseases. This is the time when man comes into the trap of erectile dysfunction. This ends an epoch of romance, passion and above all intimacy in relationship of couples. Not only this, because of erectile dysfunction and impotency, marriages has been wrecked, couples have split and individuals shattered. Erectile dysfunction is the inability of a man to uphold or reach an erection needed to satisfy his partner's sexual needs. It is visible in the men in their early fifties. Generally, it is caused by damage of nerves, arteries, smooth muscles, and fibrous tissues. High blood pressure, diabetes, heart disease, kidney or liver disease, other vascular conditions, cigarette smoking, and too much alcohol drinking, are also in charge for restricting sufficient blood-flow into the vessels of the penis, and causing ED. It is very important to treat ED on time because it may lead to low self-esteem, sexual failure anxiety, and depression, stress and guilt and relationship clashes. Most of the men throughout the world suffering from ED now rely on a drug called viagra.
