Administration of LEVITRA with nitrates and nitric oxide donors is contraindicated. Consistent with the effects of PDE5 inhibition on the nitric oxide/cyclic guanosine monophosphate pathway, PDE5 inhibitors, including LEVITRA, may potentiate the hypotensive effects of nitrates

Success Achieved (SEP2)*
and Maintained (SEP3) in ED "scrollbars=yes, resizable=yes, width=500, height=300,top=100, left=100"[1]

Men taking LEVITRA were twice as likely to maintain an erection long enough for successful intercourse (SEP3) vs placebo over a 12-week trial "scrollbars=yes, resizable=yes, width=500, height=300,top=100, left=100"[1]


SEP3 Success Rate (%) LEVITRA 10 mg and 20 mg vs placebo

LEVITRA 20 mg also demonstrated significant improvement in SEP2 and IIEF-EF "scrollbars=yes, resizable=yes, width=400, height=400,top=100, left=100"[1]§

LEVITRA 10 mg also demonstrated significant improvement in SEP2 success rate (75% vs 52% for placebo) and IIEF-EF domain score (21 vs 15 for placebo); (P<0.0001) "scrollbars=yes, resizable=yes, width=400, height=400,top=100, left=100"[1]

* Success = "yes" to Sexual Encounter Profile question 2 (SEP2): "Were you able to insert your penis into your partner's vagina?"
Success = "yes" to Sexual Encounter Profile question 3 (SEP3): "Did your erection last long enough to have successful intercourse?"
Results based on a double-blind, randomized, placebo-controlled, fixed-dose trial in a general ED population of 762 North American men, aged 20 to 83 years (mean age 57 years), receiving placebo or 5-mg, 10-mg, or 20-mg doses of LEVITRA over 12 weeks. "scrollbars=yes, resizable=yes, width=400, height=400,top=100, left=100"[2]
