If it’s not treated, the condition can damage the tissues in your penis and cause irreversible erectile dysfunction.

The pharmacokinetics of sildenafil in patients with severely impaired hepatic function (Child-Pugh Class C) have not been studied. A starting dose of 25 mg should be considered in patients with any degree of hepatic impairment [see Dosage and Administration (2.5) and Clinical Pharmacology (12.3)]. Co-administration of ritonavir, a strong CYP3A4 inhibitor, greatly increased the systemic exposure of sildenafil (11-fold increase in AUC). It is therefore recommended not to exceed a maximum single dose of 25 mg of VIAGRA in a 48 hour period [see Dosage and Administration (2.4), Warnings and Precautions (5.6), Clinical Pharmacology (12.3)]. Use caution when co-administering alpha-blockers with VIAGRA because of potential additive blood pressure-lowering effects. Prolonged erection greater than 4 hours and priapism (painful erections greater than 6 hours in duration) have been reported infrequently since market approval of VIAGRA.

Viagra (sildenafil) exerts a therapeutic effect by inhibiting the enzyme phosphodiesterase type 5 (PDE5), leading to increased levels of cyclic guanosine monophosphate (cGMP) in the penis. Sildenafil is available in three different dosages – 25mg, 50mg and 100mg. Taken around 60 minutes before sex it helps men with erectile dysfunction get and keep an erection. The dose that’s right for you will depend on a few different factors.
The maximum dose of Viagra within a 24-hour period would be 100mg. Studies have shown that a higher dose than 100mg in one day doesn’t have any added benefit – and could increase the chances of side effects. Both Viagra and sildenafil are considered effective treatments for ED. The colour and shape of the pill have no impact on how effective the treatment is. The main difference between generic medication, such as sildenafil, and brand-name medication, such as Viagra, is the purchase price and the appearance of the pill. Spedra is, in particular, an effective and fast-acting ED medication that can take effect as quickly as 20 minutes after use — and can help you to achieve and maintain an erection for a window of 4-5 hours.
Viagra is remarkably well tolerated and free from significant side effects in the vast majority of men who take it. Viagra increases blood flow which can have adverse effects on other parts of the body, although these are usually mild. Most men who experience side effects carry on treatment regardless.

Figure 6 shows that regardless of the baseline levels of function, subsequent function in patients treated with VIAGRA was better than that seen in patients treated with placebo. At the same time, on-treatment function was better in treated patients who were less impaired at baseline. The physiologic mechanism of erection of the penis involves release of nitric oxide (NO) in the corpus cavernosum during sexual stimulation. In volunteers with hepatic impairment (Child-Pugh Class A and B), sildenafil clearance was reduced, resulting in higher plasma exposure of sildenafil (47% for Cmax and 85% for AUC).
VIAGRA film-coated tablets are blue, with a rounded-diamond shape. They are marked "VIAGRA" on one side and "VGR 25", "VGR 50" or "VGR 100" on the other side.

Do not take VIAGRA film-coated tablets in combination with VIAGRA orodispersible tablets.
There is a stereotypical view of men’s sexual urges – that all men want sex all the time. This generalisation can make life especially challenging for the 40% of men who have difficulty getting, and keeping, an erection before they hit 40, and over 50% of men who have some difficulty after 40. If sildenafil tablets are not working, you should continue to take the tablets and use them on 8 separate occasions.

50mg is the standard starting dosage for sildenafil (Viagra). If 50mg does not produce the desired effect, or the effect does not last long enough, then taking two 50mg sildenafil tablets could be more effective. Doctors recommend trying the initial prescribed dose several times before deciding to change dosage. Higher doses increase the possibility of unwanted side effects.
