Cobra-120
In brief
- Cobra-120 (sildenafil citrate) is not licensed in the UK; licensed sildenafil medicines are prescription-only medicines (POM).
- Cobra-120 is used for erectile dysfunction. It contains sildenafil citrate, a phosphodiesterase type 5 (PDE5) inhibitor that increases blood flow to the penis during sexual stimulation.
- The usual dose for erectile dysfunction is 50–100 mg taken as needed, about 30–60 minutes before sexual activity. Cobra-120 contains 120 mg, which is above the standard starting dose and should only be used with medical advice.
- The form of administration is an oral tablet.
- It usually starts working within about 30–60 minutes after taking it.
- The duration of action is typically around 4–6 hours.
- Do not drink excessive alcohol, as it may increase dizziness, lower blood pressure, and make it harder to achieve an erection.
- The most common side effects are headache, flushing, nasal congestion, indigestion, dizziness, and visual disturbance.
- Would you like to try Cobra-120 without a prescription?

Cobra 120 at a glance
Cobra 120 contains sildenafil citrate, the same active ingredient as better-known sildenafil tablets, but the 120 mg strength sits above the usual starting dose.
It is not licensed in the UK and should be treated as a high-strength sildenafil tablet that needs proper caution.
What the product is, and why the 120 mg strength matters
Cobra 120 is a 120 mg tablet of sildenafil citrate, used for erectile dysfunction on demand rather than as a daily treatment.
The strength matters because most men are started on 50 mg, with some moving to 100 mg if needed and tolerated.
A 120 mg tablet is therefore above usual first-line guidance and may raise the chance of dose-related side effects.
The best results come from matching the right dose to the person, not simply picking the biggest tablet.

Product identity and packaging details
Brand name and manufacturer
Cobra 120 is reported with HAB Pharmaceuticals & Research Ltd. as the manufacturer, with Pharmax Lifesciences also reported as an alternative supplier.
Packaging format
The most common format is a blister pack, usually 4 or 10 tablets per strip or carton.
Regulatory status in the UK
Why Cobra 120 is not a standard UK-licensed medicine
Cobra 120 is not licensed or approved by the MHRA.
Sildenafil citrate itself is licensed in the UK under other brands, but that does not make every imported version equivalent in regulatory terms.
Prescription-only rules
In the UK, licensed sildenafil medicines are prescription-only (POM).
Who Cobra 120 is intended for, and who should not use it
Main use: erectile dysfunction and on-demand treatment
Cobra 120 is intended for adult erectile dysfunction treatment, taken on demand before sexual activity.
It does not treat the cause of ED itself, but it can help with erection support when sexual stimulation is present.
Why the 120 mg strength is outside usual starting doses
A clinician would usually begin with 50 mg, then adjust to 100 mg if needed.
Because Cobra 120 is 120 mg, it sits above most official starting doses and should only be considered with medical supervision.
Groups where use is not appropriate or requires specialist advice
- Suitable: adult men with erectile dysfunction who have had a proper medical review.
- Needs specialist advice: older adults, people with liver or kidney impairment, or anyone taking interacting medicines.
- Not suitable: children, women, and anyone not cleared for sexual activity because of unstable heart conditions.
How Cobra 120 works in the body
PDE5 inhibition explained in plain English
Sildenafil is a phosphodiesterase type 5 inhibitor, with ATC code G04BE03.
In simple terms, it helps increase blood flow to support an erection by reducing the action of PDE5 in penile tissue.
Why sexual stimulation is still required
The tablet does not create an erection on its own.
Sexual stimulation is still needed, which is why patients sometimes think the medicine has failed when the timing or context is wrong.
What users typically notice: timing, firmness, duration
Most men notice an effect around 30 to 60 minutes after taking it.
The erection support is usually firmer and easier to maintain during sexual activity, but the duration varies by person and dose.
Mechanism: sildenafil citrate → PDE5 inhibition → improved blood flow → erection support → sexual stimulation still required.
Dosing guidance and practical use in adults
Standard sildenafil doses versus Cobra 120
For ED, the usual adult dose is 50 to 100 mg, taken before intercourse.
Cobra 120 exceeds that usual range, so it is not a routine first choice for new users.
When to take it, and how long before intercourse
Take sildenafil about 30 to 60 minutes before sexual activity.
That timing gives the medicine enough time to start working without feeling rushed.
Maximum frequency and why “more is not better”
Use it no more than once in 24 hours.
More frequent dosing does not improve performance safely and may increase the risk of headache, flushing, dizziness, or low blood pressure.
Adjustments for older adults and impaired liver/kidney function
| Group | Suggested starting point | Practical precaution |
|---|---|---|
| Most adults with ED | 50 mg | Adjust only if tolerated and needed |
| Elderly | 25 to 50 mg | Start low and go slow |
| Liver or kidney impairment | 25 mg | High-dose tablets are not recommended |
| Cobra 120 users | 120 mg tablet | Only with explicit healthcare provider consent |
Missed dose, overdose, and urgent warning signs
Why missed dose guidance is usually irrelevant for ED use
There is no missed-dose problem with on-demand erectile dysfunction treatment.
If the timing is wrong, the answer is usually to wait and plan the next dose properly rather than taking extra tablets.
Signs of overdose and what needs urgent medical help
- Severe hypotension or fainting.
- Prolonged erection.
- Severe headache or marked vision changes.
- Chest pain, palpitations, or other cardiovascular symptoms.
When priapism becomes an emergency
Priapism is a prolonged erection that does not settle as it should.
If that happens, urgent medical treatment is needed to protect penile tissue and reduce the risk of lasting harm.
Contraindications
Absolute contraindications, especially nitrates
Do not use sildenafil with nitrate-containing drugs because the interaction can cause life-threatening hypotension.
That includes people who are already taking treatment where nitrate exposure is part of their cardiac care.
Heart, liver, and activity restrictions
People with severe cardiovascular or hepatic impairment may not be suitable for treatment.
Anyone advised against sexual activity because of unstable heart conditions should not use Cobra 120.
Allergy and excipient-related precautions
Known allergy to sildenafil or excipients is another clear stop sign.
Those are not issues to “test and see”; they need review before any tablet is taken.
| Situation | Do not use | Needs medical review |
|---|---|---|
| Nitrate-containing medicines | Yes | No |
| Known sildenafil allergy | Yes | No |
| Severe cardiovascular or hepatic impairment | Often yes | Specialist decision only |
| Unstable heart conditions | Yes | No |
Relative contraindications and interaction risks
Penile anatomy, retinal disease, and bleeding risk
Some conditions do not absolutely forbid sildenafil, but they do need careful review.
These include Peyronie’s disease, retinitis pigmentosa, bleeding disorders, and active peptic ulcer.
Blood pressure concerns and cardiovascular monitoring
Hypotension or poorly controlled hypertension can make treatment less predictable.
In those cases, the main concern is not just the tablet, but the wider cardiovascular risk profile.
CYP3A4 inhibitors and inducers
CYP3A4 is an enzyme involved in medicine breakdown.
If a person takes a strong CYP3A4 inhibitor or inducer, sildenafil levels can shift in ways that change safety and effect.
- Peyronie’s disease or other penile deformity.
- Retinal disorders such as retinitis pigmentosa.
- Bleeding disorders or active peptic ulcer.
- Low blood pressure or poorly controlled hypertension.
- Strong CYP3A4 interacting medicines.
Side effects: what is common, what users often report, and what to watch
Mild to moderate effects seen in practice
The most commonly reported effects include headache, flushing, nasal congestion, indigestion, nausea, and dizziness.
These are often temporary, but they matter more when the tablet strength is high.
Visual and muscular effects that can unsettle first-time users
Some people notice blurred vision or colour changes.
Mild back pain or muscle pain can also happen and may feel surprising if the medicine is new to the user.
When side effects mean stopping and seeking advice
| Effect | Typical severity | Practical advice |
|---|---|---|
| Headache | Mild to moderate | Monitor; seek advice if persistent or severe |
| Flushing | Mild | Usually settles on its own |
| Nasal congestion | Mild | Usually temporary |
| Blurred vision | Needs caution | Stop and speak to a pharmacist or prescriber |
| Dizziness | Needs caution | Avoid driving and sit or lie down if affected |
Cobra 120 compared with other ED treatments
Same active ingredient, different strengths
Cobra 120 contains sildenafil, the same active ingredient as Viagra, but at a much higher strength; licensed sildenafil tablets come in 25 mg, 50 mg and 100 mg strengths, which fit standard ED titration better.
When tadalafil, vardenafil or avanafil may be discussed instead
Tadalafil, vardenafil and avanafil are other ED medicines that differ in dose and how they are used.
Tadalafil is available in 2.5 mg to 20 mg strengths, vardenafil in 5 mg, 10 mg and 20 mg, and avanafil in 50 mg, 100 mg and 200 mg.
