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.

Maximising Viagra's Effectiveness: Lifestyle Tips

When Does Viagra Start Working?

Viagra contains sildenafil citrate, which typically begins to take effect within 30 to 60 minutes of consumption. However, the exact timing can vary depending on several factors including your metabolism, what you've eaten, and your overall health. Some men may notice effects as early as 15 minutes, while others might need to wait up to 2 hours.

Factors That Affect Viagra's Onset Time

Several lifestyle factors can influence how quickly Viagra works. Heavy or fatty meals can significantly delay absorption, potentially adding 30-60 minutes to the usual onset time. This is why many healthcare providers recommend taking Viagra on an empty stomach or after a light meal for optimal results.

Alcohol consumption can also affect timing and effectiveness. While small amounts may not cause issues, excessive alcohol can delay the medication's onset and reduce its effectiveness. Additionally, alcohol can contribute to erectile dysfunction itself, counteracting the benefits of treatment.

Planning for Best Results

To optimise your experience with Viagra, consider taking it approximately one hour before planned sexual activity. Remember that sexual arousal and stimulation are still necessary - Viagra doesn't cause automatic erections but enhances your natural response when aroused.

The effects of Viagra can last 4-6 hours, though this doesn't mean you'll have an erection for this entire period. Instead, it means you'll be able to achieve erections more easily during this timeframe when sexually stimulated.

Choosing Between Branded and Generic Options

At EverydayMeds, you can choose between branded Viagra and generic sildenafil during checkout. Both contain exactly the same active ingredient (sildenafil citrate) and work identically. The generic option often provides a more cost-effective choice while maintaining the same effectiveness and safety profile.

When to Seek Additional Support

If you find that Viagra isn't working as expected, don't simply increase the dose yourself. Speak with a healthcare provider who can assess whether your dosage needs adjustment, if there are underlying factors affecting effectiveness, or if alternative treatments might be more suitable. Our clinical team at EverydayMeds is available to provide guidance and support throughout your treatment journey.

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.
