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.

Clinical Guidance for Optimal Viagra Performance

How Viagra Works in Your Body

Viagra contains sildenafil citrate, a PDE5 inhibitor that blocks the enzyme phosphodiesterase type 5. This action increases blood flow to the penis during sexual arousal. Importantly, Viagra doesn't cause automatic erections - sexual stimulation is still required for the medication to be effective. The drug typically begins working within 30-60 minutes and its effects can last 4-6 hours, though this doesn't mean an erection lasts this duration.

Timing Your Dose Correctly

For best results, take your Viagra tablet 30-60 minutes before planned sexual activity. Taking it on an empty stomach may help it work more quickly, as food - particularly fatty meals - can delay absorption. The standard starting dose is 50mg, though your prescriber may adjust this to 25mg or 100mg based on your response and any side effects. Remember, only take one dose within any 24-hour period.

Lifestyle Factors That Affect Performance

Several factors can influence how well Viagra works for you. Excessive alcohol consumption may reduce its effectiveness and increase the risk of side effects like dizziness or low blood pressure. Staying adequately hydrated and maintaining a relaxed mindset can help optimise results. Stress, anxiety, and fatigue can all impact sexual performance, even when taking medication.

Choosing Between Viagra and Sildenafil

EverydayMeds offers both branded Viagra and generic sildenafil tablets. Both contain the same active ingredient and work identically - the main difference is cost. Generic sildenafil provides the same clinical effectiveness at a lower price point. During your online consultation, you can select your preferred option at checkout based on your personal preferences and budget.

When to Seek Medical Advice

If Viagra doesn't work effectively after several attempts, speak with your prescriber about adjusting your dose or exploring alternative treatments. Never exceed the recommended dose or combine with other ED medications. Contact emergency services immediately if you experience an erection lasting more than 4 hours, as this requires urgent medical attention.

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.
