Generic Viagra Medications

Sildenafil Citrate is the core element in generic Viagra drugs. Sildenafil works by expanding blood vessels and increasing circulation. These medications keep cGMP from being degraded by an enzyme called PDE5, allowing nitric oxide to be released into the penis, leading to smooth muscle relaxation and improved vasodilatation. As a result of this, the blood inflow into the penis increases, which combined with arousal leads to an erection.

Erectile dysfunction patients take this drug on an 'as-needed basis,' but ideally not more often than once every 24 hours. Before patients can buy cheap generic Viagra online without prescription, they should pay a visit to their local doctor, so that he or she can can prescribe an appropriate course of treatment for each individual case. Sildenafil Citrate is taken about an hour or so before sexual relations, on an empty stomach or with a light meal, preferably avoiding food with a high fat content, since this substance can arrest the progress of Sildenafil. Alcohol should be avoided as well, for similar reasons.

As it occurs with most medications, there are diverse generic Viagra side effects that you should learn about. These adverse effects are more often than not very mild and occur in only a small percentage of users, and abate after one or two hours. The most common side effects are facial flushing, stuffed nose, headaches, dizziness, vision difficulties, mild hearing issues, slight memory loss and chest or back ache.

It is also important to take certain precautions into consideration. First of all, you should check with a local doctor to see whether or not you are allergic to Sildenafil Citrate. When you visit your doctor, it is essential to mention if you are currently taking any other drugs or have other conditions that could have an influence on treatment with generic Viagra products.
