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.

Proper Viagra Dosage and Administration

Getting Started with Viagra

When you buy Viagra online through EverydayMeds, you'll receive clear dosage instructions following your consultation. The standard starting dose is 50mg, taken approximately one hour before sexual activity. Depending on how well you respond and any side effects experienced, your dose may be adjusted to 25mg or increased to 100mg. Remember that both branded Viagra and generic sildenafil contain the same active ingredient and work identically.

Timing Your Dose

Viagra should be taken 30-60 minutes before you plan to be sexually active. The medication can remain effective for up to 4-6 hours, though this doesn't mean you'll have an erection for this entire period. Sexual stimulation is still required for the medication to work. Taking Viagra on an empty stomach typically results in faster absorption, whilst fatty meals may delay its effectiveness by up to an hour.

Important Safety Guidelines

Never take more than one Viagra tablet in a 24-hour period, regardless of the strength. Taking multiple doses won't improve effectiveness but significantly increases the risk of serious side effects. If you're taking any medications containing nitrates (such as GTN spray for chest pain), you must not use Viagra as this combination can cause a dangerous drop in blood pressure.

What to Expect

Most men notice Viagra's effects within 30-60 minutes of taking it. You may experience mild side effects such as headache, flushing, or indigestion, which are generally temporary. If you experience an erection lasting more than 4 hours, seek immediate medical attention. This rare but serious condition requires urgent treatment to prevent permanent damage.

Choosing Between Viagra and Sildenafil

At checkout, EverydayMeds patients can choose between branded Viagra and generic sildenafil. Both contain identical active ingredients and work in exactly the same way. Generic sildenafil offers the same clinical effectiveness at a lower cost, whilst some patients prefer the original branded version. Your prescriber can help you decide which option might be most suitable for your needs and budget.

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.
