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.

Prescription Viagra vs Viagra Connect: Duration Compared

How Long Does Viagra Actually Work?

Viagra contains sildenafil citrate, which typically remains effective for 4-6 hours after taking. However, this doesn't mean you'll maintain an erection for this entire period - the medication creates a window of opportunity where achieving an erection becomes easier with sexual stimulation. The duration can vary based on factors including your age, metabolism, dosage taken, and whether you've consumed food or alcohol.

Prescription Viagra: Flexible Duration Control

When you choose prescription Viagra through EverydayMeds, you benefit from personalised dosing options. Starting with 50mg, your dose can be adjusted to 25mg if you experience side effects, or increased to 100mg if 50mg proves insufficient. Higher doses may work for longer periods and provide more reliable effects, though they also increase the likelihood of experiencing side effects like headaches or flushing.

Viagra Connect Limitations

Viagra Connect, available over-the-counter, is restricted to 50mg tablets only. Whilst this may be sufficient for some men, others might find this fixed dose less effective or shorter-lasting compared to prescription alternatives. You cannot adjust the strength with Viagra Connect, potentially limiting its effectiveness for your specific needs.

Factors Affecting How Long Viagra Works

Several elements influence sildenafil's duration and effectiveness. Large or fatty meals can delay absorption, reducing how quickly it works and potentially shortening its effective period. Alcohol consumption may also impact performance, though moderate amounts don't typically interfere with the medication's duration. Age plays a role too - older men often metabolise sildenafil more slowly, potentially extending its effects.

Branded vs Generic Options at EverydayMeds

At checkout, you can choose between branded Viagra and generic sildenafil - both containing identical active ingredients and offering the same duration of action. Generic sildenafil provides excellent value whilst delivering equivalent effectiveness to the branded version. This choice allows you to access the same 4-6 hour window of enhanced erectile function at a more affordable price point.

Maximising Viagra's Effectiveness Duration

To optimise how long Viagra works for you, take it on a relatively empty stomach 30-60 minutes before anticipated sexual activity. Avoid excessive alcohol consumption and maintain a healthy lifestyle including regular exercise and a balanced diet. Remember that sexual arousal remains essential - sildenafil enhances your natural response rather than creating automatic erections.

When to Consider Prescription Alternatives

If Viagra Connect's 50mg strength doesn't provide sufficient duration or effectiveness, prescription options through EverydayMeds may be more suitable. Our online consultation process allows UK-licensed prescribers to assess your needs and recommend appropriate dosing. This personalised approach often results in better outcomes and more predictable duration of effects.

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.
