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.

Understanding Viagra's Timeline

Viagra generally begins working within 30-60 minutes of taking the tablet on an empty stomach. However, this timeframe can extend to 90 minutes or longer if you've consumed a large or fatty meal beforehand. The medication reaches peak concentration in your bloodstream approximately 60 minutes after ingestion, which is why many healthcare providers recommend taking it about an hour before planned sexual activity.

Factors That Affect How Quickly Viagra Works

Several factors can influence how long Viagra takes to work in your system. Age plays a significant role, as older men may experience a longer onset time due to slower metabolism. Food intake is particularly important - fatty meals can delay absorption by up to 60 minutes. Alcohol consumption may also affect the medication's effectiveness and timing. Additionally, your overall health, particularly cardiovascular fitness and any underlying medical conditions, can impact how quickly you feel the effects.

Accessing Viagra Through EverydayMeds Online Consultation

Getting started with Viagra treatment through EverydayMeds is straightforward and completely confidential. Our online consultation process begins with a comprehensive medical questionnaire that takes just a few minutes to complete. You'll provide information about your medical history, current medications, and specific symptoms. This information is essential for our UK-registered doctors to determine whether Viagra or sildenafil is suitable for you and to recommend the appropriate dosage.

During the consultation, you can choose between branded Viagra and generic sildenafil. Both contain the same active ingredient - sildenafil citrate - and work in exactly the same way. The main difference is cost, with generic sildenafil offering a more economical option while maintaining identical effectiveness. Our doctors will review your consultation within 24 hours and, if approved, your prescription will be prepared for dispatch.

Dosage Options and Timing Recommendations

Viagra is available in three strengths: 25mg, 50mg, and 100mg tablets. Most men start with the 50mg dose, which can then be adjusted based on effectiveness and any side effects experienced. The maximum recommended dose is 100mg, and you should never take more than one tablet in a 24-hour period. For optimal timing, take your prescribed dose approximately 30-60 minutes before you plan to be sexually active, remembering that sexual stimulation is still required for the medication to be effective.

What to Expect During Treatment

Once Viagra begins working, its effects can last for approximately 4-6 hours. This doesn't mean you'll have an erection for this entire time - rather, it's the window during which you may find it easier to achieve and maintain an erection when sexually aroused. The medication enhances your natural response to sexual stimulation by improving blood flow to the penis. Many men find that knowing the timing helps reduce anxiety and improves their overall experience with the treatment.

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.
