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 Problems & Quick Fixes

Not Working as Expected?

If Viagra isn't providing the results you anticipated, several factors could be affecting its performance. The most common issue is timing - Viagra typically works within 30-60 minutes of taking, but large or fatty meals can delay this significantly. Try taking your tablet on an empty stomach or after a light meal for optimal absorption.

Dosage Considerations

Starting with 50mg is standard, but this may need adjustment. If you're finding the effects too mild, your prescriber might increase your dose to 100mg. Conversely, if you're experiencing unwanted side effects, reducing to 25mg could help. Never adjust your dose without medical guidance, and remember the maximum is one tablet per 24 hours.

Lifestyle Factors Affecting Performance

Alcohol can significantly reduce Viagra's effectiveness whilst increasing side effect risks. Excessive alcohol consumption may prevent you from achieving an erection even with treatment. Similarly, recreational drugs, particularly those containing nitrates, can create dangerous interactions. Stress, anxiety, and relationship issues can also impact results despite medication.

When Viagra Doesn't Suit You

Some men find branded Viagra doesn't agree with them due to side effects like headaches, flushing, or stomach upset. Generic sildenafil contains the same active ingredient but may have different inactive components. EverydayMeds offers both options, allowing you to discuss alternatives with your prescriber if needed.

Getting Professional Help

If problems persist after trying these troubleshooting steps, contact your prescriber. They can review your medical history, current medications, and lifestyle factors to identify potential issues. Sometimes switching between branded and generic versions, adjusting timing, or exploring alternative ED treatments may be more suitable for your circumstances.

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.
