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.

How Viagra Works and What to Expect

Understanding Viagra's Mechanism of Action

Viagra contains sildenafil citrate, which belongs to a class of medications called PDE5 inhibitors. When you become sexually aroused, your body naturally produces nitric oxide, which triggers a cascade of chemical reactions that increase blood flow to the penis. Viagra works by blocking the PDE5 enzyme, which normally breaks down the chemicals responsible for maintaining this increased blood flow. This allows the blood vessels in the penis to remain dilated for longer periods, making it easier to achieve and maintain an erection.

What Viagra Will Do For You

Viagra may help men with erectile dysfunction achieve firmer, longer-lasting erections suitable for sexual activity. Most men notice effects beginning 30-60 minutes after taking the medication, with peak effectiveness occurring around 1-2 hours. The medication doesn't cause spontaneous erections - sexual arousal and stimulation are still necessary. Effects can last up to 4-6 hours, though this doesn't mean you'll have an erection for this entire period. Instead, it means you may find it easier to achieve erections during this window when sexually aroused.

Factors That Influence Viagra's Effectiveness

Several factors can impact how well Viagra works for you. Taking the medication on an empty stomach typically produces faster results, as fatty foods can delay absorption by up to an hour. Alcohol consumption should be limited, as excessive drinking can impair the medication's effectiveness and increase the risk of side effects. Stress, anxiety, and relationship issues can also affect results, as psychological factors play a significant role in sexual function. Your overall health, fitness level, and whether you smoke may also influence how well the medication works.

Dosage and Timing Considerations

Viagra is available in 25mg, 50mg, and 100mg strengths. Most men start with 50mg, though your prescriber may recommend a different dose based on your health status and needs. The medication should be taken no more than once in 24 hours, typically 30-60 minutes before anticipated sexual activity. Some men find taking Viagra at a consistent time helps them plan their intimate moments better. If the initial dose isn't effective enough, your healthcare provider may adjust the strength, but never increase the dose on your own.

Maximising Your Success With Viagra

To get the best results from Viagra, maintain realistic expectations about what the medication can achieve. It treats the physical aspects of erectile dysfunction but doesn't address underlying relationship or psychological issues. Regular exercise, a healthy diet, and stress management can all enhance the medication's effectiveness. Communicate openly with your partner about your treatment, as their understanding and support can significantly improve your experience. Keep track of what works best for you in terms of timing, food intake, and circumstances.

Branded vs Generic Options

At EverydayMeds, you can choose between branded Viagra and generic sildenafil. Both contain the same active ingredient and work identically - the main difference is cost. Generic sildenafil offers the same clinical benefits at a lower price point, while some patients prefer the branded version. Your choice between Viagra and sildenafil comes down to personal preference and budget considerations, as both are equally effective when prescribed and used appropriately.

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.
