Sildenafil puede disminuir el flujo de sangre al nervio óptico del ojo, causando pérdida de la visión de formar súbita. Esto ha sucedido en un número peque?o de personas que tomaron sildenafil, de las cuales la mayoría también tenían enfermedad del corazón, diabetes, presión arterial alta, colesterol elevado, o algunos problemas del ojo preexistentes, y en personas que fumaban o tenían más de 50 a?os. No se entiende con claridad si sildenafil es la causa de pérdida de la visión.The recommended dose for ritonavir-treated patients is 25 mg prior to sexual activity and the recommended maximum dose is 25 mg within a 48 hour period because concomitant administration increased the blood levels of sildenafil by 11-fold [see Warnings and Precautions (5.6), Drug Interactions (7.4), and Clinical Pharmacology (12.3)].

These events, which may be accompanied by tinnitus and dizziness, have been reported in temporal association to the intake of PDE5 inhibitors, including Viagra. 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)].
Findings in a well-established, long-term cohort study suggest a positive association between PDE5A inhibitor (sildenafil) use for ED and risk of subsequent melanoma. Our study cannot prove cause and effect. A longer follow-up and more detailed assessment of the dose and frequency of sildenafil use at multiple times in the HPFS would be necessary for future studies. We also plan to work on clinical databases to examine this association. Further studies are needed to confirm our findings in other populations, particularly in a dose-dependent manner, and to investigate underlying biological mechanisms. It would also be very important to examine the possible latency of exposure to PDE5A inhibitor (sildenafil) use and melanoma risk. Our results should be interpreted cautiously and are insufficient to alter current clinical recommendations. Nevertheless, our data provide epidemiological evidence on possible skin adverse effects of PDE5A inhibitors and support continued investigation of this relationship.
