Genuinely non-prescription, genuinely authorised, and usable by men who cannot take PDE5 inhibitors.
Approved components, used conventionally, but with something about the format, the price or the process worth knowing before you buy.

Read this first
We are a competitor of the companies reviewed on this page. That is a conflict of interest and you should read everything here with it in mind. What we can offer against it: every factual claim is drawn from the company's own published material and linked, every clinical criticism applies equally to us where it applies, and we take no affiliate commission or referral fee from anyone named here — including from the retail pharmacies whose generics we rate most highly.
The only product authorised for over-the-counter sale to treat erectile dysfunction in the United States — and it contains no drug at all, which turns out to be the most useful thing about it.
Not verified at source
Built from the FDA's own announcement and from trade and clinical coverage, corroborated across several independent outlets rather than read on the manufacturer's page. The regulatory status, mechanism and indication are well established in that reporting; US pricing and availability were not settled at the time we checked.
Reported specifications
- What it is
- A non-medicated hydro-alcoholic gel applied to the glans immediately before intercourse. It contains no active drug.
- Regulatory status
- Authorised by the FDA on 13 June 2023 under the De Novo pathway — a medical device classification, not a drug approval
- Indication
- Erectile dysfunction in adult males aged 22 and over
- Mechanism
- The alcohol and water evaporate, producing rapid local cooling of the glans followed by slower warming, stimulating nerve endings
- Onset
- Manufacturer states around 10 minutes
- Key comparator study
- FM71: 24-week, at-home, randomised, unblinded study in 96 men comparing MED3000 against tadalafil 5mg
- Prescription
- None required
Our assessment
This entry corrects something. We have written at length about products sold without a prescription and framed that category as supplements of doubtful content. That was incomplete: there is exactly one product authorised for over-the-counter sale to treat erectile dysfunction in the United States, and this is it.
The regulatory detail matters and is routinely reported loosely. Eroxon was authorised under the De Novo pathway as a medical device, not approved as a drug. That is not a lesser status so much as a different one, and it follows from how the product works: there is no active pharmaceutical ingredient. The gel evaporates, the glans cools rapidly and then rewarms, and that thermal change stimulates nerve endings. It is physics rather than pharmacology.
Which produces the genuinely valuable consequence. A man who takes nitrates for angina cannot take any PDE5 inhibitor — sildenafil, tadalafil, vardenafil, avanafil, or any compounded combination of them — because the interaction can drop blood pressure catastrophically. That contraindication is absolute and it is the single most important safety line on this entire site. A product containing no drug does not create that interaction. For men in that position, whose options have historically been [a vacuum device](/treatments/vacuum-erection-device) or [injection therapy](/treatments/injection-therapy), a topical gel bought off a shelf is a real addition.
Now the caveats, and they are about evidence rather than safety. The headline comparator study was unblinded, and it enrolled 96 men. Unblinding matters more than usual here, because the entire mechanism is a sensation the user can feel — a participant knows immediately whether he applied a cooling gel or swallowed a tablet, and expectation effects in erectile dysfunction trials are large. That is not a reason to dismiss the product; it is a reason to hold the effect size loosely.
The onset claim of around ten minutes, against thirty or more for a PDE5 inhibitor, is plausible given the mechanism and is one of the more defensible speed claims in this market. It is also the sort of comparison worth reading alongside [what the trial evidence actually shows about fast-acting formulations](/journal/does-dissolvable-ed-medication-work-faster).
On price, roughly thirty dollars for four single-use tubes works out around $7.50 a use — more than generic tadalafil at about a dollar a tablet. You are paying for not needing a prescription, which for some men is exactly what they want to buy.
Reasonable for
- Men taking nitrates, for whom every PDE5 inhibitor is absolutely contraindicated
- Men who want to try something without a prescription and want the one option that is actually authorised
- Men who cannot tolerate the side effects of oral medication
- Men with milder difficulty who would prefer not to take a systemic drug
Not for
- Men who have not had their erectile dysfunction assessed — an OTC product examines nothing, and this symptom is frequently the first sign of vascular disease
- Men expecting the effect size of a PDE5 inhibitor at maximum dose
- Men who would read a device authorisation as equivalent to a drug approval
