About this comparison & dissolve times
“Others” means traditional swallowed ED tablets and chewable mints. It does not include other sublingual products. Their ingredients, instructions and onset vary by prescription.
For context, other sublingual brands also publish dissolve times: Ro Sparks says around 10 minutes and Rugiet Ready says 5–10 minutes. Rocket Melts’ around 2–3 minute dissolve is shorter than those stated times. These are product descriptions, not a head-to-head clinical study or a claim covering every product on the market.

Sildenafil typically starts working in 30–60 minutes. Timing and results vary, and sexual stimulation is still needed. Follow the instructions on your prescription.
Is sildenafil the same ingredient as Viagra®?
Yes. Sildenafil is the active ingredient in Viagra®. Generic sildenafil is an FDA-approved medication. Your clinician determines the right treatment and strength for you.
How is the final price confirmed?
The starting price is per tablet or mint. Your total depends on the prescribed treatment, strength and quantity. Final pricing is shown before checkout.

Is the packaging discreet?
Yes. Orders are sent in plain outer packaging without RocketRx branding or labels identifying the treatment.

Good to know before you begin.
Prescription treatment requires a clinical assessment. Do not use ED medication with nitrates or “poppers,” or with riociguat. Tell your clinician about all medicines and health conditions. Never combine ED treatments unless specifically directed by your prescriber. Seek urgent medical care for an erection lasting more than 4 hours, or sudden vision or hearing loss. Individual results vary.
