Eroxon (MED3000) topical gel
The first ED treatment you can just buy — and it contains no drug at all
Our overall score

The short version
Eroxon is a single-use gel applied to the head of the penis that works by rapid evaporative cooling followed by warming, stimulating nerve endings to trigger blood flow. It received FDA authorisation for over-the-counter sale in June 2023 and reached US shelves in late 2024. It is less effective than a PDE5 inhibitor and costs more per use than generic sildenafil — but it needs no prescription and, containing no drug, carries no nitrate interaction.
Our verdict: Genuinely useful, and genuinely oversold if you read it as a Viagra replacement. The response rate is below what pills achieve and the per-use cost is higher than generic sildenafil. Its real value is that it is drug-free: it is the only legitimate over-the-counter option in the US, and the only one a man on nitrates can buy off a shelf.
Best for: People who cannot take PDE5 inhibitors — particularly anyone on nitrates — and people who want to try something without a consultation first.
What works
- The only legitimate over-the-counter ED treatment available in the US
- Contains no drug, so there is no nitrate interaction and nothing to interact with your other medication
- Works in about 10 minutes — faster than any oral tablet
- No consultation, no subscription, no account
- Usable alongside other treatments, since it is not pharmacological
What to watch
- Meaningfully less effective than a PDE5 inhibitor
- More expensive per use than generic sildenafil
- Single-use tubes, so ongoing cost scales directly with frequency
- Evidence rests largely on manufacturer-run trials
- Requires applying a gel at the moment, which some find breaks the mood
At a glance
- How it works
- A gel applied to the glans that evaporates rapidly, producing a cooling sensation followed by warming. The temperature change stimulates nerve endings, which triggers the vasodilation that produces an erection. There is no active pharmaceutical ingredient.
- Time to effect
- About 10 minutes
- How you get it
- Over the counter, no prescription or consultation required
- Regulatory status
- Granted FDA over-the-counter marketing authorisation in June 2023; drug-free, so it is regulated on a device rather than a drug pathway
- Typical cost
- Around $25.99 for four single-use tubes — roughly $6.50 per use
- Ongoing cost
- Per use, with no subscription
- Clinical standing
- Too new to appear in the major guidelines. Its evidence base is manufacturer-run trials reviewed by the FDA, with little independent replication so far
A treatment with no drug in it
Every other option on this site works pharmacologically — a molecule that changes what your blood vessels do. Eroxon does not contain one.
The gel is applied to the head of the penis and evaporates quickly, producing a distinct cooling sensation followed by warming. That temperature swing stimulates the dense nerve endings in the glans, and that stimulation triggers the vasodilation that produces an erection. The mechanism is physical, not chemical, which is why it is regulated on a device pathway rather than as a drug.
How well does it actually work?
The headline figure from the trials submitted to the FDA is that over 60% of participants with mild, moderate, or severe ED experienced a clinically meaningful improvement in erectile function.
That is a real result and it is worth taking seriously. It also deserves two caveats.
- “Clinically meaningful improvement” is a lower bar than “erection sufficient for sex.” It is a threshold change on a questionnaire score, not a binary success rate. The two are frequently conflated in the marketing.
- PDE5 inhibitors generally do better. Response rates for sildenafil and tadalafil in comparable populations tend to run higher. If you can safely take a pill, the pill is more likely to work.
The honest positioning is not *better than Viagra*. It is *available without a prescription, safe with nitrates, and works for a majority of people who try it*.
The cost is the surprise
At roughly $25.99 for four single-use tubes, Eroxon works out around $6.50 a use.
Generic sildenafil, with a discount card, frequently costs less than that per tablet — sometimes far less. So the over-the-counter product is the more expensive option per use, which is the reverse of what most people assume.
Who it genuinely suits
- Anyone taking nitrates. This is the strongest case for it by a distance.
- People who cannot tolerate PDE5 inhibitors — headache, flushing, visual disturbance, or back pain.
- People who want to try something before seeing anyone. No account, no questionnaire, no subscription.
- People who need it to work fast, since 10 minutes beats every oral option including avanafil.
- Occasional use, where per-use pricing beats a monthly plan.
What it does not fix
Eroxon versus the alternatives
| Eroxon | Generic sildenafil | Vacuum device | |
|---|---|---|---|
| Prescription needed | No | Yes | No |
| Time to effect | ~10 minutes | 30–60 minutes | 1–3 minutes |
| Cost per use | About $6.50 | Often under $2 | Effectively zero after purchase |
| Safe with nitrates | Yes | No — never | Yes |
| Effectiveness | Moderate | High | High |
| Main drawback | Costs more than pills, works less well | Needs a prescription | Mechanical, kills spontaneity |
For someone who can safely take a PDE5 inhibitor, the pill is more effective and cheaper. For someone who cannot, Eroxon and a vacuum device are the two drug-free options — and Eroxon is by far the easier to try.
A note on what this changes
Until recently, everything sold over the counter for erectile dysfunction was, in our assessment, worth avoiding — herbal supplements with no evidence and a persistent record of being spiked with undeclared prescription drugs.
Eroxon is the first over-the-counter product we can point to that went through a regulatory review, publishes trial data, and contains what it says it contains. It is not the most effective treatment available. It is the first one you can buy on a shelf without us telling you not to.
Common questions
Does Eroxon actually work?
In the trials submitted to the FDA, over 60% of participants with mild, moderate, or severe ED had a clinically meaningful improvement in erectile function. That is a genuine result, though a lower bar than “erection sufficient for sex”, and PDE5 inhibitors generally perform better. If you can safely take a pill, a pill is more likely to work.
Can I use Eroxon if I take nitrates for my heart?
Yes — this is its single strongest advantage. Eroxon contains no active drug and works by a physical cooling-then-warming mechanism, so it does not carry the nitrate interaction that makes PDE5 inhibitors dangerous. It is the only over-the-counter ED product in the US that a man on nitrates can use.
Do I need a prescription?
No. The FDA granted over-the-counter marketing authorisation in June 2023, and the product reached US retail in late 2024. You can buy it without a consultation.
How much does it cost?
Around $25.99 for four single-use tubes, so roughly $6.50 per use. That is more per dose than generic sildenafil with a discount card — you are paying for over-the-counter access rather than for a cheaper treatment.
How fast does it work?
About 10 minutes, which is faster than any oral tablet including avanafil. There is no food effect to plan around either, since nothing is being absorbed into your bloodstream.
Can I use it with Viagra or Cialis?
There is no pharmacological interaction, because Eroxon contains no drug. That said, if a PDE5 inhibitor alone is not working, that is worth raising with a clinician rather than layering products — an inadequate response to a properly dosed pill is itself useful diagnostic information.
Is it the same as the herbal products sold in petrol stations?
No, and the distinction matters. Eroxon went through FDA review, publishes trial data, and contains no undeclared ingredients. Herbal “male enhancement” products are subject to none of that and have repeatedly been found spiked with prescription drugs. See our review of that category.
