Once the effects of Viagra have worn off, it’s likely the side effects will too. If you are worried about the side effects you are experiencing, contact your doctor for advice. Several factors can affect how long Viagra lasts including, your age, health, diet, and alcohol consumption. It is noteworthy that before the invention of Viagra, there were no effective and at the same time safe ways to deal with erectile dysfunction. All of them were fraught with serious consequences for the body of men and mostly had a narcotic character.

At 24 hours the plasma levels of sildenafil were still approximately 200 ng/mL, compared to approximately 5 ng/mL when sildenafil was dosed alone. VIAGRA had no effect on ritonavir pharmacokinetics [see Dosage and Administration (2.4) and Drug Interactions (7.4)]. It is not possible to determine whether these events are related directly to the use of PDE5 inhibitors or to other factors [see Adverse Reactions (6.1, 6.2)]. After patients have taken VIAGRA, it is unknown when nitrates, if necessary, can be safely administered. The effectiveness of sildenafil has been confirmed in numerous clinical studies. It helps most men achieve and maintain an erection sufficient for sexual intercourse.

But worrying about whether Viagra will work or not, can hinder its effectiveness. It is recommended that you take Viagra on eight separate occasions before deciding if it is working or not. This gives your body time to adjust and come to terms with the idea of taking a tablet before sexual arousal to support an erection. If&nbsp
