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.

Common Viagra 100mg Issues & Solutions

Why Isn't My Viagra 100mg Working?

If Viagra 100mg isn't providing the expected results, several factors could be involved. The most common issue is timing - Viagra works best when taken 30-60 minutes before sexual activity on a relatively empty stomach. Fatty meals can significantly delay absorption, reducing effectiveness. Remember that sexual arousal is essential; Viagra enhances natural responses rather than creating automatic erections.

Dosage Considerations

Viagra 100mg is the maximum recommended dose and may not be suitable for everyone. Some patients respond better to 50mg, whilst others may need to start with 25mg if they experience side effects. Your prescriber can adjust your dosage based on effectiveness and tolerability. EverydayMeds offers all three strengths of both Viagra and sildenafil, allowing flexible dosing options.

Timing and Food Interactions

For optimal results, take Viagra 100mg approximately one hour before anticipated sexual activity. Avoid large or fatty meals beforehand, as these can delay the medication's onset. Alcohol should be limited, as excessive consumption can interfere with the medication's effectiveness and increase the risk of side effects like dizziness or low blood pressure.

When to Seek Medical Advice

Contact your prescriber if Viagra 100mg consistently fails to work after 4-6 attempts, or if you experience concerning side effects such as prolonged erections lasting over 4 hours, chest pain, or sudden vision changes. Your healthcare provider may recommend switching to generic sildenafil or adjusting your treatment plan based on your individual response.

Alternative Options

If Viagra 100mg isn't suitable, generic sildenafil contains the same active ingredient at a lower cost. EverydayMeds provides both options during checkout, allowing you to choose based on your preferences and budget. Your prescriber may also consider alternative ED treatments if sildenafil-based medications aren't effective.

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.
