Important Safety information Sparks is a compounded prescription drug that contains sildenafil and tadalafil and is used to treat erectile dysfunction (ED). Compounded drugs are permitted to be prescribed under federal law but are not FDA-approved and do not undergo FDA safety, effectiveness, or manufacturing review by the FDA. Do not take Sparks more than once in any 24-hour period or within 24 hours of taking any other ED medications or PDE-5 inhibitors, such as tadalafil or sildenafil. Do not take Sparks if you take nitrates or soluble guanylate cyclase stimulators, as this can result in a sudden, dangerous drop in blood pressure.

Do not use it if you are not healthy enough for sex. Seek emergency care if an erection lasts longer than 4 hours. Use caution when taking alpha-blockers or drugs used to treat high blood pressure, or if drinking more than 5 units of alcohol. Seek emergency care if a sudden loss of vision occurs in one or both eyes, or if a sudden decrease or loss of hearing occurs. The most common side effects of Sparks are headache, flushing, indigestion, abnormal vision, back pain, muscle pain, nasal congestion, dizziness, nausea, pain in limb, and rash.

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.

No more timers. No more mental math. Just fast-acting treatment that lasts longer.
