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.

Timing Your Viagra Dose for Maximum Effectiveness

Optimal Timing for Viagra

Viagra should be taken approximately 30-60 minutes before you plan to engage in sexual activity. This timing allows the medication to be absorbed into your bloodstream and begin working effectively. The active ingredient sildenafil citrate requires time to inhibit the PDE5 enzyme and increase blood flow to the penis when sexual arousal occurs.

Food and Timing Considerations

What you eat before taking Viagra can significantly impact its effectiveness. Heavy or fatty meals can delay the medication's absorption, potentially extending the time before it begins working. For optimal results, consider taking Viagra on an empty stomach or after a light meal. If you've consumed a large meal, you may need to wait longer than the typical 30-60 minutes for the medication to take effect.

Duration of Effects

Viagra's effects typically last between 4-6 hours after taking the tablet. This doesn't mean you'll maintain an erection for this entire period - sexual stimulation is still required for the medication to work. The 4-6 hour window simply indicates how long the medication remains effective in your system, allowing for spontaneity during this timeframe.

Dosage and Frequency Guidelines

Most patients start with a 50mg dose of Viagra, which can be adjusted to 25mg or 100mg based on effectiveness and tolerability. Crucially, you should never take more than one dose within a 24-hour period, regardless of the strength. Taking multiple doses can increase the risk of serious side effects, particularly dangerous drops in blood pressure.

Choosing Between Viagra and Sildenafil

EverydayMeds offers both Viagra (the branded version) and Sildenafil (the generic alternative) at checkout following your consultation. Both contain the same active ingredient and work identically - the main difference is cost, with Sildenafil typically being more affordable. Your choice between branded and generic options won't affect the timing recommendations outlined above.

When Viagra May Not Work Optimally

Several factors can affect Viagra's effectiveness and timing. Excessive alcohol consumption can impair the medication's ability to work and may delay its onset. Stress, anxiety, and certain medical conditions can also impact effectiveness. If you find Viagra isn't working as expected, consult with a healthcare professional rather than adjusting the timing or dosage yourself.

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.
