Fildena: UK Status, Risks & the Licensed Equivalent

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

Fildena has no UK product license in the United Kingdom. It may still appear 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 question sellers who make bold claims about it. A status that is not clearly stated 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.

These numbers are an estimate, based on public UK pricing references such as the NHS Drug Tariff, not a quote from any specific pharmacy. What you pay can differ by pharmacy and where you are, so use these figures for comparison only. A price well below the listed range should be treated as a red flag about the seller's license.

About Fildena

Fildena is not a licensed medicine in the United Kingdom and cannot legally be sold there as a medicine. It is also marketed under the name Fildena Extra Power.

Sildenafil is the licensed active-ingredient comparison. The product's strength and formulation are not listed, so its contents and suitability should not be assumed from its name or advertising.

Claimed strengths are manufacturer claims, but no specific strength is listed for Fildena or Fildena Extra Power. The product's dosage form is also not listed. The Extra Power name does not establish a measurable strength, and there is no listed strength to compare with licensed sildenafil.

What Fildena is used for

Fildena is marketed for erectile difficulties, with sildenafil as the licensed active-ingredient comparison. This is a marketing claim, not evidence that this particular product has been assessed for effectiveness or quality. Sildenafil medicines are used to help achieve and maintain an erection when there is sexual stimulation.

They do not increase sexual desire or address every possible reason for erectile difficulties. The name Fildena Extra Power does not establish a particular strength or a greater treatment effect. A doctor or pharmacist can discuss licensed sildenafil and whether it is suitable for the person's circumstances.

How Fildena works

Sildenafil belongs to a class of medicines called phosphodiesterase inhibitors. These medicines slow the breakdown of a chemical messenger involved in relaxing blood vessels. In erectile tissue, this helps blood flow increase during sexual stimulation, making an erection easier to achieve and maintain.

The effect depends on sexual stimulation rather than producing an automatic erection. This describes the general action of sildenafil, not independently verified performance of Fildena. A product name alone cannot establish its contents, absorption or effect.

Key warnings

  • Fildena lacks licensing as a medicine in the United Kingdom; its contents and quality have not been independently verified.
  • Sildenafil can cause headache, flushing, indigestion, dizziness and visual disturbances.
  • An erection that is prolonged or painful needs urgent medical attention.
  • Sudden loss of vision or hearing needs urgent medical assessment.
  • Heart conditions and low blood pressure can affect whether sildenafil is suitable.

Main interactions

  • Nitrate medicines, including treatments for angina, can cause a dangerous fall in blood pressure with sildenafil.
  • Recreational nitrites, often called poppers, 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 may increase dizziness or fainting.
  • Some antifungal medicines, antibiotics and antiviral medicines can increase sildenafil exposure.
  • Other medicines for erectile difficulties may increase adverse effects when combined with sildenafil.

Missed dose

Sildenafil used for erectile difficulties is generally used when needed rather than as a routine daily treatment, so a missed-dose situation may not apply. Other uses can involve a regular prescribed regimen. Any uncertainty about a missed dose should be discussed with a pharmacist, using the instructions for the particular licensed medicine.

Pregnancy and breastfeeding

Fildena's marketing material does not specify pregnancy or breastfeeding data. Sildenafil for erectile difficulties is not intended as a treatment during pregnancy or breastfeeding. Sildenafil may be prescribed for other conditions under medical supervision, so questions about exposure or suitability should be discussed with a doctor or pharmacist.

Storage

No storage conditions are listed for Fildena. General medicine storage practice is to keep the product in its original packaging, away from heat and moisture, and out of the sight and reach of children.
