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 Prescription Viagra Last?

Prescription Viagra contains sildenafil citrate in doses of 25mg, 50mg, or 100mg. The duration of effects typically ranges from 4-6 hours, though this varies between individuals. Higher doses generally provide longer-lasting effects, with 100mg potentially maintaining effectiveness for up to 6 hours. It's important to understand that Viagra doesn't cause a continuous erection - rather, it enables natural erections when sexually aroused during this timeframe.

Viagra Connect Duration and Limitations

Viagra Connect, available over-the-counter, contains 50mg sildenafil - the standard starting dose. Whilst convenient, it may not provide optimal duration for all men. Those requiring longer-lasting effects might benefit from prescription alternatives, including higher doses or generic sildenafil. The fixed 50mg dose cannot be adjusted without prescription supervision, potentially limiting effectiveness for some patients.

Factors Affecting Viagra Duration

Several factors influence how long Viagra lasts in your system. Age plays a significant role, with older men typically experiencing longer duration due to slower metabolism. Food intake affects onset and duration - fatty meals can delay effectiveness and reduce duration. Alcohol consumption may diminish effects and shorten duration. Individual metabolism, overall health, and other medications also impact how long sildenafil remains active.

Dosage Options for Optimal Duration

Prescription Viagra allows dosage customisation based on individual needs. Starting with 50mg, your prescriber may adjust to 25mg if you experience side effects, or increase to 100mg for enhanced duration and effectiveness. This flexibility isn't available with Viagra Connect's fixed dose. Generic sildenafil provides identical duration and effectiveness at significantly lower cost, making it an excellent alternative to branded Viagra.

Maximising Viagra Effectiveness and Duration

To optimise Viagra's duration, take it on a relatively empty stomach 30-60 minutes before sexual activity. Avoid excessive alcohol, which can reduce effectiveness and duration. Stay hydrated and maintain good overall health through regular exercise and balanced nutrition. If duration seems insufficient, consult with a prescriber about adjusting your dose or considering alternative treatments.

Safety Considerations for Extended Use

Never exceed one dose per 24-hour period, regardless of desired duration. If you experience an erection lasting over 4 hours, seek immediate medical attention. Men taking nitrates for heart conditions cannot safely use any form of sildenafil. Always complete a thorough medical assessment before starting treatment, whether prescription Viagra or Viagra Connect.

Choosing Between Viagra and Generic Sildenafil

Both branded Viagra and generic sildenafil provide identical duration and effectiveness, as they contain the same active ingredient. The primary difference is cost - generic sildenafil typically costs significantly less whilst offering the same clinical benefits. EverydayMeds provides both options, allowing you to choose based on personal preference and budget considerations following your online consultation.

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.
