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.

Understanding Viagra's Timeline and Effectiveness

When Does Viagra Start Working?

Viagra, containing the active ingredient sildenafil citrate, typically begins working within 30 to 60 minutes after taking the tablet. However, this timeframe can vary between individuals based on several factors. The medication reaches peak concentration in your bloodstream approximately one hour after consumption, which is when most men report optimal effectiveness.

Factors That Influence Viagra's Working Time

Several elements can affect how quickly Viagra starts working. Taking the medication on an empty stomach generally leads to faster absorption and quicker results. Fatty or heavy meals can delay the onset by up to an hour, as food interferes with the absorption process. Your age, overall health, and metabolism also play roles in determining response time.

Duration of Effects

Once Viagra begins working, its effects typically last between 4 to 6 hours. This doesn't mean you'll maintain an erection for this entire period - rather, you'll have an enhanced ability to achieve and maintain erections when sexually aroused during this window. The medication only works in response to sexual stimulation and doesn't cause automatic erections.

Optimising Your Results

To achieve the best results with Viagra, consider taking it approximately one hour before planned sexual activity. Avoid excessive alcohol consumption, as this can interfere with the medication's effectiveness and may increase the risk of side effects. Staying relaxed and managing stress can also improve your response to the treatment.

Choosing Between Viagra and Generic Sildenafil

At EverydayMeds, we understand that cost can be a significant consideration when choosing ED treatment. Generic sildenafil contains exactly the same active ingredient as branded Viagra and works in precisely the same way, offering identical effectiveness and safety profiles. The main difference lies in the price - generic sildenafil typically costs significantly less than the branded version, making it an excellent value option for many patients.

Dosage Considerations

Viagra is available in 25mg, 50mg, and 100mg strengths. Most men start with the 50mg dose, which can be adjusted up to 100mg or down to 25mg based on effectiveness and tolerance. Remember that you should only take one dose within any 24-hour period, and it's essential to follow the guidance provided by your healthcare provider.

Safety and Eligibility

Before starting Viagra treatment, you'll need to complete a clinical assessment to ensure the medication is safe for you. This evaluation considers your medical history, current medications, and overall cardiovascular health. Viagra isn't suitable for men taking nitrates for chest pain or those with certain heart conditions, as dangerous interactions can occur.

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.
