Ro Sparks work faster because it is administered under the tongue. This means that the medication is absorbed directly into the bloodstream via the blood vessels under the tongue, rather than getting absorbed in the stomach.

Ro Sparks are a sublingual formulation, meaning they are dissolved under the tongue. ED medications that are sublingual formulations have been shown to work in as little as 15 minutes on average.*

Ro Sparks contain tadalafil, which lasts in the bloodstream for up to 36 hours.

For most people, it dissolves in 10 minutes on average.

Ro Sparks are very intentionally designed to dissolve under your tongue for several minutes as opposed to instantly. This maximizes the amount of medication delivered directly to your bloodstream for a faster effect, compared to rapid-dissolving or swallowed tablets which are often absorbed through your digestive tract.

Sparks are $12 per dose on a monthly subscription plan. Quarterly plans also available.*

For comparison, we offer traditional 50mg generic Viagra tablets at $6 per dose and 20mg generic Cialis tablets at $44 per dose on monthly plans. These are also available in quarterly, semi-annual, and annual plans.

You may cancel your plan at any time in your Ro account. Your provider will recommend the best treatment regimen for you.
