Zenegra: UK Status, Risks & the Licensed Equivalent

Written by Vaibhav Modgil, MBChB, MD, FRCS(Urol) · Last updated

Zenegra is not licensed as a medicine in the UK for sale in the UK. Some sellers may still list it, but its safety and effectiveness have not been assessed by the MHRA.

Speak with a UK-registered prescriber before deciding anything about it, and question sellers who make bold claims about it. An unclear licensing status is itself worth asking about.

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.

About Zenegra

Zenegra is not a licensed medicine in the United Kingdom and cannot legally be sold there as a medicine. Its contents, quality and manufacturing standards are not independently verified for United Kingdom patients. The product is associated with sildenafil, an active ingredient used in medicines for erectile difficulties, but Zenegra should not be treated as an approved or clinically validated product.

The product label does not list a claimed strength, dosage schedule or administration instructions. Claimed strengths are manufacturer claims, but no specific strength is listed for Zenegra.

This information does not establish a dose or make the product suitable for use. A doctor or pharmacist can discuss an appropriate licensed sildenafil medicine and its approved directions.

What Zenegra is used for

Zenegra is marketed in connection with sildenafil and claimed to help adults with erectile difficulties. This is a marketing claim rather than an established medical indication for Zenegra, because the product is not a licensed medicine in the United Kingdom and its quality has not been independently verified.

Erectile difficulties can have physical, psychological or medicine-related causes. A doctor or pharmacist can assess whether a licensed sildenafil medicine or another option is suitable, particularly where symptoms are new, persistent or accompanied by other health concerns.

How Zenegra works

Sildenafil belongs to a class of medicines called phosphodiesterase type five inhibitors. In response to sexual stimulation, these medicines help preserve chemical signals that relax smooth muscle and widen blood vessels in the penis. This can increase blood flow and support an erection.

Sexual stimulation is still needed; sildenafil does not generally create sexual desire or produce an erection without stimulation. The effect can be affected by other medicines, alcohol and underlying cardiovascular problems. Zenegra itself has not been independently verified as a medicine, so the amount and activity of sildenafil in a product sold under that name may not be reliable.

Main interactions

  • Nitrate medicines can interact dangerously with sildenafil-class medicines and cause a substantial fall in blood pressure.
  • Riociguat can interact with sildenafil-class medicines and is generally not used with them.
  • Alpha-blockers and other blood-pressure-lowering medicines may increase the risk of dizziness or low blood pressure.
  • Some medicines that inhibit liver enzymes can increase sildenafil exposure and side effects.
  • Other treatments for erectile difficulties may produce additive effects and should not be combined without clinical advice.
  • Large amounts of alcohol can worsen dizziness and make an erection more difficult to achieve.

Key warnings

  • Zenegra is not a licensed medicine in the United Kingdom and cannot legally be sold there as a medicine.
  • The product's identity, contents, strength, quality and manufacturing have not been independently verified.
  • Sildenafil-class medicines can cause headache, flushing, indigestion, dizziness, visual disturbance and changes in blood pressure.
  • Chest pain, fainting, sudden visual loss or a prolonged or painful erection require urgent medical attention.
  • Sildenafil-class medicines may be unsuitable for some people with cardiovascular disease or low blood pressure.
  • A registered United Kingdom pharmacy or a doctor can advise on a licensed alternative.

Pregnancy and breastfeeding

The marketing material does not specify pregnancy or lactation data for Zenegra. Sildenafil is not generally used to treat erectile difficulties in pregnancy, and use during pregnancy or breastfeeding should be discussed with a doctor or pharmacist. The lack of independent verification for Zenegra makes self-use particularly inappropriate during pregnancy or lactation.

Missed dose

Sildenafil-class medicines are generally used when needed rather than as a regular course, so a missed dose may not apply. The product label does not provide a dosing schedule.

A missed scheduled dose should not be replaced by taking extra medicine. A doctor or pharmacist can explain what to do if a licensed sildenafil treatment has been prescribed, taking account of the prescribed directions and other medicines.

Storage

No storage conditions are listed for this product. Keep the packaging closed, dry and away from excessive heat, direct sunlight and children.

Do not use a product if the packaging is damaged or the contents have changed. A pharmacist can advise on disposal of unwanted or suspect medicines.
