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.

How to Get Viagra Safely in the UK

Prescription Requirements and Legal Status

Viagra is classified as a prescription-only medicine (POM) in the United Kingdom, requiring a valid prescription from a UK-licensed healthcare professional. EverydayMeds offers convenient online consultations where qualified prescribers assess your medical history, current medications, and cardiovascular health to determine suitability. During checkout, patients can choose between branded Viagra or generic sildenafil - both contain the same active ingredient but sildenafil typically costs less.

Dosage and Usage Guidelines

Viagra is available in three strengths: 25mg, 50mg, and 100mg tablets. Most men start with 50mg, taken approximately 30-60 minutes before sexual activity. The dose may be adjusted to 25mg if side effects occur, or increased to 100mg if 50mg proves insufficient. Only one dose should be taken within any 24-hour period. Fatty meals can delay the medication's onset of action, so consider timing of food intake.

Who Can Take Viagra?

Adult men aged 18 and over experiencing erectile dysfunction may be suitable candidates for Viagra treatment. However, the medication is not appropriate for everyone. Men taking nitrate medications for chest pain, those with severe heart conditions, recent stroke or heart attack, severe liver problems, or very low blood pressure should not use Viagra. The online consultation process helps identify these contraindications before prescribing.

Expected Effects and Effectiveness

Viagra works by increasing blood flow to the penis during sexual arousal - it does not cause automatic erections. The medication typically becomes effective within 30-60 minutes and effects may last up to 4-6 hours, though this doesn't mean an erection will persist for this duration. Sexual stimulation remains necessary for the medication to work. If Viagra proves unsuitable or ineffective, alternative ED treatments may be recommended.

Side Effects and Safety Considerations

Common side effects of Viagra may include headache, facial flushing, indigestion, nasal congestion, and temporary vision changes. Most side effects are mild and resolve naturally. Serious side effects are rare but include prolonged erections lasting over four hours (priapism) and sudden vision or hearing loss - both require immediate medical attention. Never combine Viagra with nitrate medications as this can cause dangerous drops in blood pressure.

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.
