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.

Troubleshooting Guide for Viagra Effectiveness

Why Viagra May Not Be Working

If you're experiencing problems with Viagra, several factors could be affecting its effectiveness. The most common issue is timing - Viagra works best when taken 30-60 minutes before sexual activity on an empty stomach. Fatty meals can delay absorption for up to 2 hours, whilst alcohol can reduce blood flow and counteract the medication's effects.

Dosage Adjustments May Help

Many men start with 50mg Viagra, but this isn't always the optimal dose. If you're not seeing results, speak with your prescriber about adjusting to 25mg or 100mg. EverydayMeds offers all three strengths of both branded Viagra and generic Sildenafil, allowing you to find the most effective dose whilst managing costs.

Common Side Effects and Solutions

Headaches, facial flushing, and indigestion are normal side effects that often improve with continued use. Taking Viagra with plenty of water and avoiding alcohol can reduce these effects. If you experience severe side effects like chest pain or prolonged erections lasting over 4 hours, seek immediate medical attention.

When to Consider Sildenafil Generic

Generic Sildenafil contains the same active ingredient as Viagra but costs significantly less. Many patients find switching to the generic version helps them access consistent treatment without financial pressure. Both options are available through EverydayMeds following our clinical consultation process.

Lifestyle Factors Affecting Performance

Stress, anxiety, smoking, and underlying health conditions can all impact Viagra's effectiveness. Regular exercise, a healthy diet, and managing cardiovascular health often improve treatment outcomes. If problems persist despite proper usage, consult your healthcare provider about alternative ED treatments or underlying health issues.

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.
