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 Storage & Timing: Essential Guidelines

How Long Before Viagra Works

Viagra typically begins working within 30-60 minutes of taking, though this timing can be influenced by various factors. The medication reaches peak blood levels approximately 60 minutes after administration. Sexual stimulation is required for the medication to be effective, as Viagra enhances natural erectile response rather than causing automatic erection.

Factors Affecting Viagra Timing

Food intake significantly impacts how quickly Viagra works. Taking the medication on an empty stomach generally results in faster onset, whilst fatty meals can delay absorption by up to 60 minutes. Alcohol consumption may also slow the medication's effectiveness and should be limited when taking Viagra or sildenafil.

Proper Storage Requirements

Correct storage is essential for maintaining Viagra's potency and ensuring it works within the expected timeframe. Store tablets at room temperature between 15-30°C, away from direct sunlight and moisture. Bathroom storage is not recommended due to humidity from showers and baths, which can degrade the active ingredient sildenafil citrate.

Original Packaging Guidelines

Keep Viagra tablets in their original blister packaging until ready to use. The packaging protects against light and moisture exposure that could compromise effectiveness. Never store loose tablets in pill organisers for extended periods, as this may affect how long before Viagra works optimally.

Temperature Control Considerations

Extreme temperatures can significantly impact Viagra's effectiveness. Avoid storing in cars during hot weather or freezing conditions. If tablets have been exposed to temperatures above 30°C or below freezing, consult with EverydayMeds pharmacists about whether replacement medication is needed.

Branded vs Generic Options

EverydayMeds offers both branded Viagra and generic sildenafil, allowing patients to choose based on preference and budget. Both medications contain the same active ingredient and require identical storage conditions. Generic sildenafil provides a cost-effective alternative whilst maintaining the same onset time of 30-60 minutes when stored correctly.

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.
