How ED treatment works in your body.

Increases blood flow

Increases blood flow

When PDE5 is suppressed, blood is able to flow more freely through the body—including to the (you guessed it) penis.

Increase erections

Increase erections

More blood flow to the penis means harder, more satisfying erections once you're sexually stimulated.

Essential Travel Documentation for Sildenafil

Prescription Documentation Requirements

When travelling with sildenafil (generic) or Viagra (branded), proper documentation is essential for legal transport. The BNF recommends carrying medications in original pharmacy packaging with clear dispensing labels showing patient name, prescriber details, and medication information. EverydayMeds provides comprehensive labelling on all sildenafil prescriptions to meet travel requirements.

International Travel Considerations

Different countries have varying regulations regarding sildenafil importation. Some nations require additional documentation or restrict quantities for personal use. Research destination-specific requirements before travelling, particularly for extended trips. The Foreign Office website provides country-specific medication guidance, whilst the BNF offers general travel advice for prescription medicines.

Airport Security and Hand Luggage

Pack sildenafil in hand luggage rather than checked baggage to prevent loss and temperature damage. Airport security may request prescription documentation, so keep this easily accessible. Liquid medications over 100ml require separate screening, though standard sildenafil tablets don't typically require special handling. Both generic sildenafil and branded Viagra should be transported identically.

Obtaining Additional Supplies

For extended travel periods, you may require additional sildenafil supplies. UK prescribers can provide early repeat prescriptions for travel purposes with adequate notice. EverydayMeds offers convenient online consultations for travel prescriptions, allowing patients to choose between generic sildenafil or branded Viagra based on personal preference and budget considerations.

Emergency Prescription Abroad

If medication is lost or damaged whilst travelling, obtaining emergency supplies can be challenging. Some countries may require local medical consultation or won't recognise UK prescriptions. Consider travel insurance covering prescription medication replacement, and research local medical facilities at your destination.

Storage During Travel

Sildenafil should be stored in cool, dry conditions away from direct sunlight. Extreme temperatures during travel can affect medication stability. The BNF specifies storage requirements for sildenafil as below 30°C in original packaging. Consider insulated medication cases for destinations with extreme climates.

What you need to know about erectile dysfunction

It's one of the most common conditions we treat, and one of the most treatable.

What is Erectile Dysfunction?
ED means finding it hard to get or keep an erection firm enough for sex. It's not unusual to have an off night; the point at which it's worth doing something is when it's happening regularly, or when it's starting to bother you.
How will I feel when I take ED medication?
For most men, nothing feels different day to day. The medication works in the background — when you're sexually aroused, it helps blood flow where it's needed, so erections come more easily and last longer. It doesn't cause arousal on its own. Some men notice mild, short-lived effects like a headache, facial flushing or a stuffy nose, which usually pass as the dose wears off.
Why do I need a prescription for ED medication?
ED treatments are prescription-only medicines in the UK because they aren't suitable for everyone — for example, alongside certain heart conditions or medications like nitrates. That's why we ask you to complete a short online consultation first. A UK-registered prescriber reviews your answers to make sure your chosen treatment is safe and right for you before it's dispensed.
