There is a potential for cardiac risk of sexual activity inpatients with preexisting cardiovascular disease. Therefore, treatments for erectile dysfunction, including VIAGRA, should not be generally used in men forwhom sexual activity is inadvisable because of their underlying cardiovascular status. The evaluation of erectile dysfunction should include a determinationof potential underlying causes and the identification of appropriate treatmentfollowing a complete medical assessment. It is not a replacement for consulting with a qualified healthcare professional.
However, there is currently no reliable evidence to suggest that any of these approaches are effective for treating the condition. In erectile dysfunction, however, blood flow to the penis can be too low and disrupt the ability to get or maintain an erection. Drugs such as Viagra relax smooth muscles and increase blood flow to the penis, making it easier to get or keep an erection. Viagra can help stimulate blood flow to the penis and help people with the condition maintain an erection. The products discussed in this site may have different product labeling in different countries.
The maximum recommended dose of 100 mg sildenafil was not evaluated in this study [see DRUG INTERACTIONS]. In the third study, a single oral dose of VIAGRA 100 mg or matching placebo was administered in a 3-period crossover design to 20 generally healthy males with BPH. In dose period 1, subjects were administered open-label doxazosin and a single dose of VIAGRA 50 mg simultaneously, after at least 14 consecutive days of doxazosin. If a subject did not successfully complete this first dosing period, he was discontinued from the study. Subjects who had successfully completed the previous doxazosin interaction study (using VIAGRA 50 mg), including no significant hemodynamic adverse events, were allowed to skip dose period 1. Treatment with doxazosin continued for at least 7 days after dose period 1.

A causal relationship between VIAGRA andthese events has not been established. In humans, VIAGRA has no effect onbleeding time when taken alone or with aspirin. However, in vitro studies withhuman platelets indicate that sildenafil potentiates the antiaggregatory effectof sodium nitroprusside (a nitric oxide donor). In addition, the combination of heparin and VIAGRA had an additive effect on bleeding time in the anesthetizedrabbit, but this interaction has not been studied in humans. VIAGRA has systemic vasodilatory properties and mayfurther lower blood pressure in patients taking antihypertensive medications. Based on effectiveness and toleration, the dose may be increased to a maximum recommended dose of 100 mg or decreased to 25 mg.
