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.

Optimal Timing and Dosage Guidelines for Viagra

Standard Timing Protocol

Viagra should typically be taken 30-60 minutes before sexual activity. The medication requires time to be absorbed and begin working effectively. Most men find that taking Viagra approximately one hour before intimacy provides optimal results. EverydayMeds offers both branded Viagra and sildenafil (the generic equivalent) - patients can choose their preferred option at checkout based on budget and preference.

Dosage Timing Considerations

The standard starting dose is 50mg, though your prescriber may recommend 25mg or 100mg depending on your individual circumstances. Regardless of the dose prescribed, the timing remains consistent - always allow 30-60 minutes for the medication to take effect. Remember that sildenafil requires sexual stimulation to work; it does not cause automatic erections.

Food and Alcohol Impact

High-fat meals can significantly delay Viagra's absorption, potentially extending the time before it becomes effective. For optimal timing, consider taking the medication on an empty stomach or after a light meal. Alcohol can also affect the medication's effectiveness and may delay onset, so moderate consumption is advisable.

Safety Timing Requirements

MHRA guidelines strictly limit Viagra to one dose per 24-hour period. This safety requirement applies to both branded Viagra and generic sildenafil. Never take additional doses within this timeframe, even if the initial dose seems less effective. If timing issues persist, consult your prescriber about alternative approaches rather than increasing frequency.

Duration of Effects

Viagra's effects typically last 4-6 hours, though this varies between individuals. This timeframe doesn't mean maintaining an erection for hours - rather, it represents the window during which the medication may help achieve erections when sexually stimulated. Plan accordingly and avoid taking additional doses during this period.

Special Timing Situations

Certain medications, particularly nitrates, create dangerous interactions with Viagra. If you use GTN spray or similar medications, timing becomes critical - never combine these treatments. Always inform your EverydayMeds prescriber about all medications during your consultation to ensure safe timing protocols.

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.
