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.

Viagra Onset Time: What to Expect

Understanding Viagra's Timeline

Viagra (sildenafil citrate) typically begins working within 30-60 minutes of taking the tablet. However, this timeframe can vary depending on several factors. The medication reaches peak effectiveness approximately 1-2 hours after consumption. It's important to note that sexual arousal is still required - Viagra doesn't cause automatic erections but enhances your natural response when sexually stimulated.

Factors That Affect Viagra's Onset Time

Several elements can influence how quickly Viagra takes effect. Food intake plays a significant role - taking Viagra on an empty stomach typically results in faster absorption. Large or fatty meals can delay the medication's onset by up to an hour. Alcohol consumption can also slow absorption and may reduce the medication's effectiveness. Age and overall health status can affect how quickly your body processes the medication.

Comparing Viagra Strengths and Options

Viagra is available in three strengths: 25mg, 50mg, and 100mg. The 50mg dose is typically the starting point for most men, with adjustments made based on effectiveness and tolerability. Higher doses don't necessarily work faster but may provide more pronounced effects. At EverydayMeds, we offer both branded Viagra and generic sildenafil - both contain the same active ingredient and work identically, though generic sildenafil provides excellent value for money.

Duration of Viagra's Effects

While Viagra begins working within 30-60 minutes, its effects can last 4-6 hours. This doesn't mean you'll have an erection for this entire period - rather, you may find it easier to achieve and maintain erections during this window when sexually aroused. The medication gradually leaves your system, with most men finding effects diminish after 4-5 hours.

Maximising Viagra's Effectiveness

To optimise how quickly Viagra works, consider taking it on an empty stomach or after a light meal. Avoid excessive alcohol consumption, which can impair both the medication's effectiveness and your sexual performance. Stay hydrated and try to relax - stress and anxiety can interfere with the medication's benefits. Remember that Viagra requires sexual stimulation to work effectively.

Choosing Between Branded and Generic Options

Both Viagra and generic sildenafil contain identical active ingredients and undergo the same rigorous safety testing. The main difference lies in cost - generic sildenafil typically costs significantly less while providing the same therapeutic benefits. At checkout, EverydayMeds allows you to choose between branded Viagra and generic sildenafil based on your preference and budget. Our UK-licensed prescribers will recommend the most appropriate strength following your online consultation.

When to Seek Medical Advice

If Viagra doesn't seem to work after several attempts, consult with a healthcare provider. Sometimes, adjusting the dose or addressing underlying health factors can improve effectiveness. Never exceed one tablet within 24 hours, regardless of the strength. If you experience side effects or have concerns about the medication's performance, our clinical team at EverydayMeds is available for guidance.

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.
