Viagra Extra Dosage: UK Status, Risks & the Licensed Equivalent

Written by Giulio Garaffa, MD, PhD, FRCS(Urol) · Last updated

Viagra Extra Dosage has no UK product license in the United Kingdom. Some sellers may still list it, but the MHRA has not assessed its safety or effectiveness.

Consult a qualified clinician before acting on it, and verify a seller's registration before buying. An unclear licensing status is a reasonable thing to question.

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

These numbers are an estimate, based on public UK pricing references such as the NHS Drug Tariff, not a quote you can hold a pharmacy to. Actual prices vary by pharmacy, pack and location, so check with the pharmacy for the number that applies to you. An unusually low price next to these figures should raise a red flag for an unlicensed or unsafe seller.

About Viagra Extra Dosage

Viagra Extra Dosage is not a licensed medicine in the United Kingdom and cannot legally be sold there as a medicine. Its name should not be treated as evidence of its contents, strength or quality. Licensed sildenafil is a point of comparison to discuss with a doctor or pharmacist, who can help assess suitable treatment and relevant safety concerns.

Claimed strengths are manufacturer claims; no specific strength or dosage form is listed for Viagra Extra Dosage. The product name does not establish a higher strength or a verified amount of active ingredient. With no stated strength, a meaningful comparison with the maximum strength of licensed sildenafil cannot be made.

How Viagra Extra Dosage works

Sildenafil belongs to a class of medicines called phosphodiesterase inhibitors. It slows the breakdown of a chemical messenger involved in relaxing blood vessels. In erectile tissue, this can help blood flow increase during sexual stimulation and support an erection.

It does not directly increase sexual desire, and sexual stimulation is still needed for its effect on erections. This describes the general action of sildenafil, not a verified effect of Viagra Extra Dosage, whose contents and strength have not been independently established.

What Viagra Extra Dosage is used for

Viagra Extra Dosage is marketed as a product for erection difficulties, but this is a marketing claim rather than an established medical benefit for this product. Its name does not establish that it contains a particular amount of sildenafil or that it performs like a licensed sildenafil medicine.

Sildenafil is used to help with erectile dysfunction, but that use cannot establish the effectiveness or quality of an unlicensed product. A doctor or pharmacist can discuss licensed treatment options and whether they are suitable alongside other medicines and existing health conditions.

Key warnings

  • Viagra Extra Dosage lacks licensing as a medicine in the United Kingdom, and its contents, strength and quality lack independent verification.
  • Sildenafil can lower blood pressure and may be unsuitable for people with certain heart conditions.
  • A prolonged or painful erection requires urgent medical attention.
  • Sudden loss of vision or hearing requires urgent medical attention.
  • Headache, flushing, indigestion and dizziness can occur with sildenafil.

Main interactions

  • Nitrates used for angina and recreational nitrites can cause a dangerous fall in blood pressure with sildenafil.
  • Riociguat must not be combined with sildenafil because of the risk of low blood pressure.
  • Alpha-blockers and other blood pressure medicines can increase dizziness or low blood pressure.
  • Some antifungal medicines, antibiotics and antiviral medicines can increase sildenafil levels.
  • Other medicines for erection difficulties may increase adverse effects when combined with sildenafil.

Storage

No storage conditions or dosage form are listed for Viagra Extra Dosage. Medicines should generally remain in their original packaging, away from moisture, excessive heat and children. Product-specific storage requirements should be checked with a pharmacist.

Missed dose

Missed-dose advice depends on the reason sildenafil is prescribed and the instructions for the particular licensed medicine. For erectile dysfunction, it is generally used when needed rather than as a regular course.

No missed-dose instructions are established for Viagra Extra Dosage. A pharmacist can clarify the instructions for a prescribed or pharmacy-authorised sildenafil product.

Pregnancy and breastfeeding

The marketing material does not specify pregnancy or breastfeeding data for Viagra Extra Dosage. Sildenafil use during pregnancy or breastfeeding requires a clinical assessment of the reason for treatment and potential risks. Anyone who is pregnant, planning pregnancy or breastfeeding should discuss this with a doctor or pharmacist rather than relying on this product's marketing.
