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 Why Viagra May Not Work for You

Common Reasons Viagra Doesn't Work

When Viagra fails to provide the expected results, several factors could be at play. Dosage timing is crucial - taking Viagra with a large or fatty meal can significantly delay its absorption and reduce effectiveness. Many men don't realise that Viagra should ideally be taken on an empty stomach or with a light meal for optimal results.

Alcohol consumption can also interfere with Viagra's effectiveness. While a glass or two of wine might not cause problems, excessive alcohol can impair blood flow and reduce sexual arousal, counteracting Viagra's benefits. Similarly, recreational drugs, particularly those containing nitrates, can create dangerous interactions or reduce effectiveness.

Medical Factors That Affect Viagra's Success

Underlying health conditions may prevent Viagra from working effectively. Severe diabetes can cause nerve damage that affects erectile function, whilst advanced cardiovascular disease might mean blood vessels cannot respond adequately to treatment. Low testosterone levels can also impact libido and sexual response, making Viagra less effective even when blood flow improves.

Certain medications can interfere with Viagra's action. Alpha-blockers used for prostate problems, some antidepressants, and blood pressure medications may reduce effectiveness or create unwanted interactions. It's essential to discuss all medications with your prescriber when seeking ED treatment.

Dosage and Timing Considerations

Many men start with a 50mg dose of Viagra, but this isn't always optimal. Some may need the lower 25mg dose due to side effects, whilst others require 100mg for adequate effectiveness. Your prescriber can adjust dosage based on your response and tolerability.

Timing expectations matter too. Viagra typically works within 30-60 minutes and requires sexual arousal to be effective. It won't create an automatic erection - psychological readiness and physical stimulation remain essential components of successful treatment.

Alternative Solutions and Next Steps

If standard Viagra doesn't work, several options exist. Different PDE5 inhibitors like tadalafil or vardenafil may be more suitable for some men, as they have slightly different characteristics and durations of action. These alternatives work through the same mechanism but may be more effective for certain individuals.

At EverydayMeds, patients can choose between branded Viagra and generic sildenafil at checkout. Both contain the same active ingredient, but some men find one formulation works better than the other. The generic option also provides a more cost-effective way to try different dosages.

Lifestyle modifications can significantly improve treatment outcomes. Regular exercise improves cardiovascular health and blood flow, whilst maintaining a healthy weight reduces diabetes risk and improves overall sexual health. Reducing stress through counselling or relaxation techniques may also enhance treatment effectiveness.

When to Seek Professional Guidance

If Viagra continues to be ineffective after trying different dosages and timing, it's important to speak with a healthcare professional. They can evaluate whether underlying conditions need treatment, review medications for potential interactions, or recommend alternative approaches.

Sometimes the issue isn't physical but psychological. Performance anxiety can prevent even effective medications from working properly. Counselling or therapy might be beneficial alongside medical treatment to address these concerns.

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.
