Phosphodiesterase-5 (PDE5) inhibitors have been associated with transient impairment of color discrimination (blue/green) and blue- or color-tinged vision. These agents also inhibit phosphodiesterase-6 (PDE6), to a much lesser extent, which is involved in phototransduction in the retina. There are no controlled clinical data on the safety in patients with retinitis pigmentosa, a minority of whom may have genetic disorders of retinal phosphodiesterases. Therapy with these agents should be avoided in such patients.

Secondary Outcome

In clinical studies, the incidence of bleeding (i.e., epistaxis) was increased in patients with pulmonary arterial hypertension secondary to connective tissue disease and in patients on concomitant therapy with an oral vitamin K antagonist. There have been postmarketing reports of bleeding events in patients treated with sildenafil for erectile dysfunction. Applies to: Bleeding Associated with Coagulation Defect The safety of sildenafil in patients with bleeding disorders or active peptic ulceration is unknown. Prolonged erection greater than 4 hours and priapism (painful erections greater than 6 hours) have been reported during treatment with phosphodiesterase-5 (PDE 5) inhibitors. Priapism may result in penile tissue damage and permanent loss of potency if not treated promptly.

Therefore, patients that consume alcohol should be warned to limit alcohol intake while receiving these agents. The safety of sildenafil in patients with bleeding disorders or active peptic ulceration is unknown. The most commonly reported adverse effects with sildenafil are headache, flushing and dyspepsia.

The phenylalanine content should be considered when this 50mg viagra product is used in patients who must restrict their intake of phenylalanine (i.e. Exposure to sildenafil is increased in patients with renal dysfunction. Lower starting doses of sildenafil for the treatment of erectile dysfunction (ED) are recommended in patients with severe renal impairment (CrCl less than 30 mL/min).
