Can I Use Generic Revatio as a Substitute for Viagra?

Using generic Revatio as a substitute for Viagra represents an “off-label” use of the former. And with generic alternatives to Viagra already on the market, using generic Revatio instead makes little sense at all. 

Sildenafil citrate is the active ingredient and generic equivalent of Viagra, Pfizer’s little blue pill that revolutionized the treatment of erectile dysfunction beginning in the late 1990s. Sildenafil is also the active ingredient and generic equivalent of Revatio, another Pfizer brand-name drug that was introduced to treat pulmonary arterial hypertension, a form of high blood pressure that targets the lungs.

The recommended starting dose (RSD) for Viagra or its generic equivalent is 50 milligrams, while the RSD for Revatio is 20 milligrams, a significant difference. Generic Revatio is available in 20-milligram tablets only, while generic Viagra comes in tablets of 25, 50, and 100 milligrams, which are also the strengths at which brand-name Viagra is sold.

Doesn’t Really Make Sense

Given their similarities and differences, does it make sense to use generic Revatio (20-milligram tablets) as a substitute for Viagra? And the answer is: Not really!

To begin with, to purchase generic Revatio for use in fighting erectile dysfunction, you would have to enlist the cooperation of your doctor, and he might very likely refuse to go along with your scheme. After all, the use of Revatio-strength sildenafil to treat ED represents an off-label use of the medication, one that’s generally frowned upon in the medical community.

And using 20-milligram tablets of sildenafil to treat your symptoms of ED would pose a mathematical challenge for most users of Viagra, the typical dose of which is 50 milligrams. To replicate Viagra’s RSD in generic Revatio would require the use of two and a half tablets of the latter.

No Adverse Effects Likely

Would there likely be any adverse effects from using generic Revatio to replace Viagra? Not really, unless you happened to miscalculate the amount of generic Revatio needed to approximate your typical dose of Viagra.

However, why even bother? Generic alternatives to Viagra, dispensed in the same dosage strengths as the brand-name drug, have been available to U.S. consumers since December 2017. And although the number of generic entries in the Viagra market have been limited thus far, that will likely change in April 2020 when Pfizer’s final U.S. patents on Viagra expire.

Lower Generic Viagra Prices on the Horizon

And with increased competition in the generic Viagra market, downward pressure on prices is almost certain to follow. Of the 15 generic Viagra alternatives tentatively approved by the Food and Drug Administration, seven are to be marketed by Indian-based pharmaceutical companies. The latter have a reputation for aggressive pricing strategies that promise to heat up competition and lower prices in this market starting only a few months from now.
