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.

Understanding Viagra Availability and Prescription Requirements

Can You Buy Viagra Over the Counter?

This is perhaps the most common question about Viagra availability. In the UK, Viagra Connect (50mg sildenafil) is available over the counter from registered pharmacies following a consultation with a pharmacist. However, prescription-strength Viagra and sildenafil in 25mg and 100mg doses require a prescription from a qualified healthcare provider.

The prescription requirement exists for important safety reasons. A clinical assessment evaluates your cardiovascular health, current medications, and medical history to ensure the treatment is safe and appropriate for your individual circumstances.

Viagra vs Sildenafil: Are They Really Different?

One of the biggest misconceptions is that branded Viagra is somehow superior to generic sildenafil. Both medications contain exactly the same active ingredient - sildenafil citrate. The only differences are the manufacturer, appearance, and price. EverydayMeds offers both options, allowing you to choose between branded Viagra or the more cost-effective generic sildenafil at checkout.

Generic sildenafil undergoes the same rigorous testing and quality standards as the branded version. The Medicines and Healthcare products Regulatory Agency (MHRA) ensures all medications meet identical safety and efficacy requirements.

How ED Medications Actually Work

Another common myth is that Viagra causes automatic erections. In reality, sildenafil is a PDE5 inhibitor that works by increasing blood flow to the penis when you're sexually aroused. Sexual stimulation is still required - the medication simply helps your body respond more effectively to natural arousal.

The medication typically works within 30-60 minutes of taking it, with effects lasting 4-6 hours. This doesn't mean you'll have an erection for hours, but rather that you may find it easier to achieve and maintain an erection during this window when sexually stimulated.

Dosage Flexibility and Individual Needs

Many men believe there's a standard dose that works for everyone. Actually, sildenafil is available in 25mg, 50mg, and 100mg strengths, with 50mg being the typical starting dose. Your prescriber may adjust this based on how well the medication works for you and any side effects you might experience.

Some men find the lower 25mg dose sufficient, whilst others may need the higher 100mg dose for optimal results. The key is working with your healthcare provider to find the right dose for your individual needs.

Safety Considerations and Contraindications

Perhaps the most dangerous myth is that ED medications are safe for everyone. Sildenafil can interact dangerously with certain medications, particularly nitrates used for chest pain. This combination can cause a potentially life-threatening drop in blood pressure.

The medication is also not suitable for men with severe heart conditions, recent heart attacks or strokes, or certain other health conditions. This is why the clinical assessment process is so important - it ensures the treatment is safe based on your individual health profile.

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.
