Ro Sparks contains ED medications, sildenafil and tadalafil, in a single sublingual drop.
That means you get a treatment that's designed to:
Start working quickly (15 minutes after drop dissolves, on average).
Contains tadalafil to last up to 36 hours.
Dissolve under your tongue instead of being swallowed.
Work without needing to plan around a meal.
It's a different approach to ED treatment that combines fast onset and long-lasting support, all in one medication.
How much does Ro Sparks cost?
Ro Sparks are $12/dose on a monthly subscription plan. Quarterly subscription plans are also available.
Ro offers plans with 4-14 doses per month, and your total cost will depend on the plan you choose (for a monthly plan cost ranges from $48 for 4 doses per month to $168 for 14 doses per month).
Your provider will recommend the treatment plan that's right for you.

Why Sparks
Sparks is a compounded medication. Compounded medications are not FDA-approved, but are permitted to be prescribed under federal law.
Letter from the founder
Hey there,
It’s Z, the founder of Ro.
I’ve been taking Viagra for 14 years. It’s been life-changing. It unlocked a whole new level of intimacy with my wife. It’s given me new confidence in and out of the bedroom.
But ED treatments have their limitations. Most take 45-60 minutes to work. Some last longer than others. It forced me to become a human stopwatch who can count in 45-minute and 4 or 6-hour increments (not the most useful skill). Plus, I had to time my meals to make sure the medication worked consistently.
We designed Sparks to help guys get the spontaneity back. Sparks is a compounded medication, which means it’s tailored for patients who need a dosage form for easier ingestion or faster onset of action. While compounded medications aren’t FDA-approved, they can be prescribed by your provider, if appropriate.
No more timers. No more mental math. Just fast-acting treatment that lasts longer.

Frequently asked questions about Ro Sparks
How do Ro Sparks work faster than traditional ED medications like Viagra or Cialis?
Ro Sparks dissolve under your tongue instead of being swallowed. This allows the medication to be absorbed directly into your bloodstream, rather than passing through your digestive system first. Faster absorption may help Ro Sparks work sooner than traditional sildenafil.
How long does Ro Sparks take to work?
Ro Sparks is designed to start working quickly by dissolving under your tongue. After it dissolves, it works in about 15 minutes, on average.
How long does Ro Sparks last?
Ro Sparks is a dual-action formula that contains tadalafil, an ED medication that can remain active in your bloodstream for up to 36 hours.
But that doesn't mean you'll have an erection for 36 hours; it just means the medication stays available in your body to support erections when you're sexually stimulated within that window of time.
How do you take Ro Sparks?
Take Ro Sparks at least 15 minutes before sex. Place one Ro Sparks drop under your tongue and let it dissolve completely. The drop dissolves in about 10 minutes, on average. While it's dissolving, avoid eating or drinking.
Do not take more than one dose in a 24-hour period.
How long does Ro Sparks take to dissolve?
For most people, a Ro Sparks drop dissolves in about 10 minutes, on average.
Ro Sparks is intentionally designed to dissolve gradually under your tongue. This helps maximize absorption into your bloodstream and supports a faster onset compared to medications that are swallowed.
