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 Instructions

Standard Dosing Guidelines for Viagra

The recommended starting dose for Viagra is 50mg, taken approximately one hour before sexual activity. Based on individual effectiveness and tolerability, the dose may be adjusted to 25mg for those experiencing side effects, or increased to a maximum of 100mg for improved effectiveness. It's crucial to never exceed one tablet within a 24-hour period, regardless of the strength prescribed.

Timing and Food Considerations

Viagra should be taken 30-60 minutes before anticipated sexual activity, though it may work as quickly as 30 minutes in some patients. The effects can last up to 4-6 hours, though this doesn't mean an erection will persist for this duration. Sexual stimulation is still required for the medication to be effective. High-fat meals can significantly delay absorption and reduce effectiveness, so it's advisable to take Viagra on an empty stomach or after a light meal.

Important Safety Precautions

Before taking Viagra, ensure you've disclosed all current medications during your consultation, particularly any heart medications containing nitrates, as this combination can cause dangerous drops in blood pressure. Common side effects may include headache, flushing, indigestion, or nasal congestion. If you experience an erection lasting more than four hours, chest pain, or sudden vision changes, seek immediate medical attention.

Choosing Between Viagra and Generic Sildenafil

EverydayMeds offers both branded Viagra and generic sildenafil options during checkout. Both contain the same active ingredient and work identically, with the generic version typically offering significant cost savings. The choice between branded and generic is purely personal preference, as both undergo the same rigorous safety and quality standards. Our UK-licensed prescribers can help determine the most appropriate option based on your individual needs and circumstances during the online consultation process.

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.
