At the time the study started, the FDA stated that there were sufficient routine safety data on sildenafil to make collection of standard adverse event data unnecessary. Therefore, only serious adverse events and adverse events leading to changes in dosing or to temporary or permanent discontinuation were recorded and evaluated by the investigators for relatedness to sildenafil treatment.
The population of the current 4-year open-label study of sildenafil differed from those of the pooled double-blind studies in that it was self-selected. Consequently, it is likely that men with poor tolerability or inadequate effectiveness did not opt to participate and that the population included mostly men who had previously experienced a good response to sildenafil. Also, men who could afford to purchase sildenafil may have lost incentive to participate in the long-term study when sildenafil became commercially available. This phenomenon necessitated discontinuation of a European long-term OL study when sildenafil became commercially availabile in Europe (Padma-Nathan et al 2001). Another limitation was the use of unvalidated general efficacy questions, explained by the fact that the major focus of the study was safety and by the absence at the time of the study design of appropriate validated questionnaires to assess satisfaction with ED treatment. Regardless, the results add to the previously published reports by showing continued safety and effectiveness during prolonged treatment. During 4 years of open-label, flexible-dose administration, there were few discontinuations because of either intolerable adverse events or insufficient clinical response. The majority of men were satisfied with sildenafil treatment for their ED and reported improved ability to engage in sexual activity. Throughout the 4-year study period, the consistently low incidence of adverse events of sufficient severity to negatively impact treatment argues against the loss of tolerability with time, and the low rate of discontinuation because of insufficient clinical response (
Despite a preferred sildenafil dose of 100 mg (the highest recommended dose) in more than 88% of the men, treatment-related cardiovascular adverse events necessitating changes in dosing or temporary or permanent discontinuation were limited to one case each of mild palpitations and tachycardia and 5 cases of flushing. There were no treatment-related acute myocardial infarctions or other serious adverse events. Only 1.1% of participants discontinued treatment over 4 years because of treatment-related adverse events, which were most frequently dyspepsia, rhinitis, and headache. In comparison, treatment-related adverse events were responsible for discontinuation by 1.2% of men treated with sildenafil 100 mg in 6-month, double-blind, placebo-controlled trials (Morales et al 1998) and by 2% of 1008 men enrolled in 36-week or 52-week, open-label extension studies (Steers et al 2001). Adverse events were responsible for similarly low rates of discontinuation in clinical practice studies of varying duration conducted worldwide; in California 2.7% of 74 men discontinued (Marks et al 1999), in Brazil none of 256 men discontinued (Moreira et al 2000), and in China none of 1,290 men discontinued (Jiann et al 2003). Among 22,471 men treated with sildenafil in general practice in the UK, headache was the most frequently reported treatment-related adverse event and was cited as the reason for discontinuation in 0.3% of men (Boshier et al 2004).

ViagraTM is a PDE-5 inhibitor approved by the FDA to treat erectile dysfunction (ED). It's the brand name of the specific drug made by Pfizer, who's active chemical in the medicine is sildenafil citrate.
The primary indication of sildenafil is treatment of erectile dysfunction (inability to sustain a satisfactory erection to complete sexual intercourse). Its use is now one of the standard treatments for erectile dysfunction, including for men with diabetes mellitus.
In clinical trials, the most common adverse effects of sildenafil use included headache, flushing, indigestion, nasal congestion, and impaired vision, including photophobia and blurred vision. Some sildenafil users have complained of seeing everything tinted blue (cyanopsia). This cyanopsia can be explained because Sildenafil, while selective for PDE5, does have a minor level of selectivity for PDE6, which is the phosphodiesterase found in the retina. Patients thus taking the drug may experience colorvision abnormalities. Some complained of blurriness and loss of peripheral vision. In July 2005, the U.S. Food and Drug Administration (FDA) updated labeling for Cialis, Levitra and Viagra to reflect a small number of post-marketing reports of sudden vision loss, while acknowledging that "...it is not possible to determine whether these oral medicines for erectile dysfunction were the cause of the loss of eyesight or whether the problem is related to other factors such as high blood pressure or diabetes, or to a combination of these problems." A careful review of pooled data from clinical trials containing well documented information about the dose and duration of exposure to the drug for a large number of patients, yields no evidence for an increased risk of non-arteritic anterior ischemic optic neuropathy or other adverse ocular events associated with PDE-5 inhibitor use. 
Rare but serious adverse effects found through postmarketing surveillance include prolonged erections, severe low blood pressure, myocardial infarction (heart attack), ventricular arrhythmias, stroke, increased intraocular pressure, and sudden hearing loss. In October 2007, the FDA announced that the labeling for all PDE5 inhibitors, including sildenafil, required a more prominent warning of the potential risk of sudden hearing loss.
Care should be exercised by people who are also taking protease inhibitors for the treatment of HIV infection. Protease inhibitors inhibit the metabolism of sildenafil, effectively multiplying the plasma levels of sildenafil, increasing the incidence and severity of side effects. Those using protease inhibitors are recommended to limit their use of sildenafil to no more than one 25 mg dose every 48 hours. Other drugs that interfere with the metabolism of sildenafil include erythromycin and cimetidine, both of which can also lead to prolonged plasma half-life levels.
The use of sildenafil and an α1 blocker (typically prescribed for hypertension or for urologic conditions, such as benign prostatic hypertrophy) at the same time may lead to low blood pressure, but this effect does not occur if they are taken at least 4 hours apart. 041b061a72
