About Viagra Professional

Viagra Professional is not a licensed medicine in the United Kingdom and cannot legally be sold there as a medicine. Its marketing presents it as a sildenafil-containing product for erectile difficulties, but the product information does not establish regulatory approval, quality, strength or independent verification. A doctor or pharmacist can discuss licensed sildenafil options and whether they are suitable.

The product label does not list a claimed strength, dosage schedule or directions for use. Claimed strengths are manufacturer claims only when stated on packaging or marketing material, and no such strength is listed here.

This absence means that a safe dose cannot be established from the product information. A doctor or pharmacist can advise about an appropriate licensed sildenafil product instead.

How Viagra Professional works

Sildenafil belongs to a group of medicines called phosphodiesterase type five inhibitors. During sexual stimulation, natural chemical signals can increase blood flow into erectile tissue. Sildenafil class medicines help preserve one of those signals by slowing its breakdown, which may support increased blood flow and an erection when sexual stimulation is present.

They do not usually create sexual desire and do not cause an erection independently of stimulation. The effect can be affected by health conditions, other medicines and the amount of active ingredient present. Because this product is not licensed in the United Kingdom, its contents and performance cannot be assumed to match a licensed sildenafil medicine.

What Viagra Professional is used for

Viagra Professional is marketed for erectile difficulties, meaning problems obtaining or maintaining an erection suitable for sexual activity. This is a marketing claim rather than an established medical fact about this product. Erectile difficulties can have several possible causes, including physical health conditions, medicines, psychological factors or lifestyle influences.

A doctor or pharmacist can help assess the concern and discuss licensed treatments. Persistent or newly developing symptoms may warrant medical assessment, particularly where other health problems or medicines are involved.

Key warnings

  • This product is not a licensed medicine in the United Kingdom and cannot legally be sold there as a medicine.
  • The product's contents, strength and quality have not been independently verified.
  • Sildenafil-class medicines can cause headache, flushing, indigestion, dizziness or changes in vision.
  • Chest pain during or after sexual activity needs urgent medical attention.
  • An erection that is painful or lasts unusually long requires urgent medical care.
  • Sildenafil-class medicines may be unsuitable for some people with heart or blood pressure problems. A doctor or pharmacist should assess suitability.

Main interactions

  • Nitrate medicines for chest pain can cause a dangerous fall in blood pressure when combined with sildenafil.
  • Riociguat can interact with sildenafil and may cause excessive blood pressure reduction.
  • Other medicines for erectile difficulties or treatments that widen blood vessels may increase adverse effects.
  • Some medicines that affect liver enzymes can alter sildenafil exposure and effects.
  • Alcohol may worsen dizziness or reduce sexual performance, while recreational drugs may add cardiovascular risks.

Storage

No storage conditions are listed for this product. Keep tablets in their original packaging, dry and away from excessive heat, moisture and direct light.

Store them securely and out of the reach of children. Follow any storage directions printed on the packaging to maintain quality, and do not use tablets if their appearance or packaging has changed.

Missed dose

Sildenafil-class medicines are generally used in relation to sexual activity rather than as a regular course, so a missed dose cannot be handled safely without knowing the intended regimen. The product label does not provide a dosing schedule.

A missed dose should not be replaced by taking extra tablets or combining products. A pharmacist or doctor can explain what to do for a prescribed licensed medicine.

Pregnancy and breastfeeding

The marketing material does not specify pregnancy or lactation data for Viagra Professional. Sildenafil-class medicines are not generally intended for use during pregnancy, and the potential for exposure through breastfeeding should be discussed with a doctor or pharmacist. Avoid using this unlicensed product during pregnancy or breastfeeding unless a qualified healthcare professional has given specific advice about a suitable, licensed treatment.
