Cobra online: sildenafil 120 mg, a strength that does not exist officially

Cobra is sold at 120 mg, and anyone looking at cobra online should know that this is not a strength any regulator has approved. The licensed sildenafil range is 25 mg, 50 mg and 100 mg. 120 mg sits twenty per cent above the top of it, in a gap that exists for manufacturing and marketing reasons rather than clinical ones — it reads as more than 100 without looking as reckless as 200.

What twenty per cent more sildenafil does

Very little for the erection, and a measurable amount for everything else. PDE5 inhibition is approaching saturation at 100 mg, which is why the trials stopped there: the additional efficacy above that dose was not worth the additional adverse effects. Headache, flushing and nasal congestion are dose-related and continue rising past the point where the benefit has levelled off.

There is no evidence base for 120 mg specifically. It has not been through a dose-ranging study, nobody has characterised its adverse-effect profile, and the figures quoted on this page for side effects are extrapolated from the licensed doses because that is all that exists. That is an honest limitation rather than a reason to panic — the difference between 100 and 120 is small — but it should inform the decision rather than being hidden behind the packaging.

Prices

For comparison, Cenforce covers 25 mg through 200 mg at lower prices and lets you choose a licensed strength, and generic sildenafil does the same. If the appeal of this product is the number on the box rather than anything else, those are better purchases.

Taking it

Swallow with water about an hour before sex on a relatively empty stomach; a high-fat meal delays the peak by roughly an hour and lowers it by about a third. The useful window is around four hours. One dose in twenty-four hours — and at a supratherapeutic strength that limit should be treated as firm rather than approximate.

Sexual stimulation is required. The drug prevents an erection from ending prematurely rather than producing one, and in a man who is anxious rather than aroused there is nothing for it to act on. That, not the dose, is the usual explanation when a tablet appears to do nothing.

Contraindications, which get more consequential with dose

Nitrates in every form are absolutely excluded: glyceryl trinitrate spray and tablets, isosorbide mononitrate and dinitrate, patches, and the alkyl nitrites sold as poppers. The hypotensive interaction scales with the sildenafil dose, so a supratherapeutic tablet makes a dangerous combination more dangerous rather than differently dangerous. Riociguat is excluded on the same pathway.

Alpha blockers need separation and a reduced starting dose, which this single high strength cannot provide. Strong CYP3A4 inhibitors — ketoconazole, itraconazole, ritonavir, clarithromycin, higher-dose fluconazole — raise sildenafil levels substantially; combining one with 120 mg produces concentrations nobody has studied. Recent myocardial infarction or stroke, unstable angina, severe hepatic impairment, hypotension below 90/50 and hereditary degenerative retinal disorders such as retinitis pigmentosa are contraindications.

Priapism — an erection past four hours — is a surgical emergency and the risk is dose-related. Sudden loss of vision or hearing means stopping and being assessed the same day.

Regulatory status and what it means for a buyer

Manufactured in India, with no marketing authorisation in the United States, the European Union or the United Kingdom. Sildenafil is licensed in all of them under other names; this product and this strength are not. Unlicensed sildenafil is also the most counterfeited pharmaceutical category in published regulatory data, and an unverified tablet of an unapproved strength is an unknown quantity of a vasodilator. The only workable protection is provenance and a prescription checked against what is being dispensed — on this site, through the prescription service.

If more milligrams is the plan

It is worth asking what the plan is based on. Men who move up the strengths rarely do so after four properly timed attempts at a licensed dose with real stimulation; they do so after one or two disappointing evenings. And the commonest cause of a disappointing evening is not an underdose — it is that the difficulty is not vascular.

The tell is simple: erections full on waking and when alone, failing with a partner; a start point traceable to one occasion rather than a gradual decline; a result that disappears the moment the tablets stop. No strength of sildenafil changes that. Clinical sexology works on the mechanism involved, and the first consultation at this studio is free. The alternatives, including the long-acting tadalafil, are in men's health.

Unapproved strengths, and how they come about

A manufacturer producing for unregulated export markets is not constrained by a dossier. Nothing prevents pressing a tablet at 120 mg, and there are commercial reasons to do it: the number differentiates the product on a crowded listing page, and it implies more than 100 without the obvious recklessness of 200.

What does not happen is a dose-ranging study. No regulator has reviewed 120 mg sildenafil, no trial has compared it with 100 mg, and the adverse-effect profile at that dose is extrapolated rather than measured. The difference between 100 and 120 is small enough that the extrapolation is probably reasonable — which is itself the argument against paying extra for it.

What actually improves results

In order of how often each one is the answer. Timing: an hour before, on a relatively empty stomach, with the usable window running about four hours from there. Food: a fatty meal costs an hour of onset and a third of the peak. Stimulation: the drug is permissive, and an anxious man watching for an effect is not generating the signal it amplifies. Persistence: guidance recommends four adequate attempts before judging a strength.

Then, and only then, dose. And if four adequate attempts at 100 mg have genuinely failed, the productive next move is a different molecule rather than a bigger number — tadalafil for men whose problem is timing around meals, vardenafil for those defeated by sildenafil’s side effects.

Interactions at a glance

At a supratherapeutic strength each of the first four becomes more consequential rather than differently consequential, which is the practical reason a licensed dose is the safer purchase.

What to buy instead

If the appeal of 120 mg was the number, the honest alternative is a licensed strength from a product offering the full range, titrated with a prescriber. If the appeal was that 100 mg disappointed, the alternative is a different molecule — tadalafil for men whose evenings involve dinner, vardenafil for those defeated by sildenafil’s side effects.

And if four adequate attempts at a licensed dose have genuinely failed, the alternative is a conversation rather than a purchase.

Questions

Is 120 mg noticeably better than 100 mg?

There is no study showing that it is. The efficacy curve is flattening at the top of the licensed range.

Can I split it to get 60 mg?

Approximately, but 60 mg is not a standard dose either. If you want 50 mg, buy 50 mg.

Why does the strength exist at all?

Commercial differentiation in an unregulated export market. It is not based on a trial.

What is a sensible alternative?

A licensed strength from a product that offers the full range, titrated with a prescriber — 50 mg to start for most men, 25 mg where the guidance calls for it.

The label these figures come from

The licensed dose range, the food effect, contraindications and adverse-effect frequencies are from the FDA label for sildenafil citrate; unlicensed-import guidance is published by the UK Medicines and Healthcare products Regulatory Agency.
