On October 28, 2026, Rocket Rx, the U.S. telehealth brand of UK-founded HeliosX, launched Rocket Melts. It is a fast-dissolving sublingual erectile-dysfunction treatment that combines sildenafil and tadalafil in one mint-and-citrus tablet, prescribed after an online consultation at rocketrx.com. According to the company's press release, the tablet dissolves under the tongue within 3 minutes with no water, and is "designed to deliver effective results from as few as 15 minutes, at lower doses, with the potential for fewer side effects." It comes in packs of 8, 16 and 32.

Why It Matters

Melts, chews and combo troches have become a standard way for DTC ED brands to stand out, because sildenafil and tadalafil are cheap generics and the format is the only real product differentiator left. Two-molecule compounded combos sit in a gray zone. They are legal when a clinician prescribes them for an individual patient, but the FDA has not reviewed them, and the supply chain behind compounded ED drugs has been under scrutiny since the agency's [Shoolin Pharma warning letter](/stories/fda-shoolin-compounded-ed-api-recall) found insanitary conditions at a plant supplying compounding pharmacies with sildenafil and tadalafil. Expect the format race to continue as [Hims, Ro and others](/stories/ro-robin-ai-health-agent) compete on convenience. Regulators are likely to focus on whether speed-of-onset marketing for unapproved combinations amounts to an efficacy claim.

The pitch is about spontaneity. "Many men find that planning intimacy around a pill that takes up to an hour to work can feel inconvenient or disruptive," said HeliosX North America medical director Dr. Ashley White. CMO Dr. Karim Vellani described it as a format that is "faster and more discreet to take, while every prescription stays grounded in the same clinical oversight."

The fine print matters. The release says Rocket Melts are compounded medications, and that compounded drugs "are not FDA-approved and do not undergo FDA safety, effectiveness, or manufacturing review." Onset and side-effect claims are the company's own, and the release cites no clinical data for the combination. Rocket Rx's homepage advertises access to "safe, FDA-approved medication" in general terms, but this product is not FDA-approved.
