Cobra 120: UK Status, Risks & the Licensed Equivalent

Written by Suks Minhas, MBBS, MD, FRCS(Urol) · Last updated

Cobra 120 is not a UK-licensed product under UK medicines law. It can still show up in some listings, but its safety and effectiveness have not been assessed by the MHRA.

Ask a doctor or pharmacist before deciding anything about it, and treat bold marketing claims about it with caution. A seller who is vague about licensing status should not be assumed to mean approval.

Not UK-licensed. This medicine is not supplied through UK-registered pharmacies.

Sellers list the active ingredient as sildenafil. The MHRA has not assessed what these products actually contain.

UK-licensed equivalent: Sildenafil

The MHRA warns that medicines sold outside registered pharmacies can be counterfeit, contaminated, or contain the wrong amount of active ingredient. Buy prescription-only medicines from a pharmacy registered in the UK.

as of Oct 2, 2026 · Pricing methodology

Figures shown are an estimate, assembled from public pricing references for the UK, not a price any one pharmacy has promised. What you pay can differ by pharmacy and where you are, so treat the numbers as a starting point, not a promise. A price that seems oddly cheap next to this range should raise a red flag about who is actually selling it.

About Cobra 120

Cobra 120 is not a licensed medicine in the United Kingdom and cannot legally be sold there as a medicine. It is also sold as Vega Extra Cobra.

Its strength and formulation are not listed, so the name should not be treated as proof of its contents. Sildenafil is a licensed medicine that readers can discuss with a doctor or pharmacist.

Claimed strengths are manufacturer claims, but no strength is listed for this product. The product name is not evidence of a measured amount of active ingredient.

Its formulation is also not listed. A comparison with the maximum strength of licensed sildenafil cannot be made from an unlisted strength.

What Cobra 120 is used for

Cobra 120 is presented alongside sildenafil as a point of comparison, but its marketing information does not specify a treatment claim. Sildenafil is used for erection difficulties, but that does not establish that Cobra 120 has the same contents, effects or suitability.

Any claim that this product helps with erections should be treated as a marketing claim rather than evidence of an assessed treatment. A doctor or pharmacist can explain the licensed sildenafil options and whether they are suitable.

How Cobra 120 works

Sildenafil belongs to a group of medicines called PDE inhibitors. For erection difficulties, it works by slowing the breakdown of a chemical that helps blood vessels relax in the penis. This allows more blood to enter during sexual stimulation.

It does not automatically cause an erection or increase sexual desire. This describes how sildenafil works in general, not proof that Cobra 120 contains an assessed amount of sildenafil or works in the same way.

Main interactions

  • Nitrate medicines for chest pain and nitrite products called poppers can cause a dangerous fall in blood pressure with sildenafil.
  • Riociguat can cause a dangerous fall in blood pressure when combined with sildenafil.
  • Alpha blockers and other blood pressure medicines can increase dizziness or fainting.
  • Some antifungal medicines, antibiotics and HIV medicines can increase sildenafil levels.
  • Other treatments for erection difficulties may increase unwanted effects.

Key warnings

  • Cobra 120 lacks licensing as a medicine in the United Kingdom, and its contents and strength lack independent verification.
  • Sildenafil can cause a dangerous fall in blood pressure when combined with nitrates.
  • Heart disease or low blood pressure may affect whether sildenafil is suitable.
  • An erection that is prolonged or painful needs urgent medical attention.
  • Sudden loss of vision or hearing needs urgent medical attention.

Pregnancy and breastfeeding

The marketing material does not specify pregnancy or breastfeeding data for Cobra 120. Sildenafil may be prescribed for conditions other than erection difficulties under medical supervision. Use during pregnancy or breastfeeding needs an individual assessment by a doctor or pharmacist, rather than assumptions based on the product name.

Missed dose

Sildenafil used for erection difficulties is generally used when needed rather than as a routine course, so a missed dose may not apply. Other uses can involve regular treatment. Any missed-dose advice should come from the leaflet for the prescribed medicine or a pharmacist, rather than from assumptions about Cobra 120.

Storage

No storage conditions or dosage form are listed for this product. Keep it out of the sight and reach of children, and ask a pharmacist about appropriate storage to maintain quality.
