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.

Why Viagra Might Not Be Working For You

Common Reasons Viagra May Be Ineffective

When Viagra doesn't provide the expected results, several factors could be responsible. Understanding these can help you and your healthcare provider identify potential solutions. The most common issues include incorrect timing, inadequate dosage, or interference from food and alcohol.

Taking Viagra too close to a heavy meal, particularly one high in fat, can significantly delay its absorption and reduce effectiveness. Alcohol consumption can also interfere with the medication's ability to work properly, as it affects blood flow and can counteract Viagra's mechanism of action.

Dosage Considerations and Adjustments

Many men start with a 50mg dose of Viagra, but this isn't always the optimal strength for everyone. If the initial dose hasn't been effective, your prescriber might recommend adjusting to 100mg, provided it's medically appropriate for you. Conversely, some men may benefit from starting with a lower 25mg dose and gradually increasing if needed.

At EverydayMeds, both branded Viagra and generic sildenafil are available in 25mg, 50mg, and 100mg strengths. The choice between branded and generic options doesn't affect efficacy, as both contain the same active ingredient - sildenafil citrate.

Timing and Expectations

Viagra typically begins working within 30-60 minutes of taking it, but this can vary between individuals. Some men may need to wait up to two hours to experience the full effects. It's crucial to understand that Viagra requires sexual arousal to work - it doesn't automatically cause an erection.

Taking the medication on an empty stomach or with a light meal can improve absorption and onset time. Planning intimate moments around this timing can significantly improve treatment outcomes.

Alternative ED Treatments

If Viagra continues to be ineffective despite proper usage and dosage adjustments, alternative PDE5 inhibitors might be more suitable. Medications like tadalafil (Cialis) have a longer duration of action and may work better for some men. Vardenafil (Levitra) is another option that some find more effective than sildenafil.

Each PDE5 inhibitor has slightly different characteristics in terms of onset time, duration, and how they're affected by food and alcohol. Your healthcare provider can help determine which might be most appropriate based on your individual circumstances and lifestyle.

Underlying Health Factors

Certain medical conditions can affect how well Viagra works. Diabetes, cardiovascular disease, neurological conditions, and hormonal imbalances can all impact erectile function and medication effectiveness. Addressing these underlying health issues alongside ED treatment often improves outcomes.

Psychological factors such as anxiety, stress, or depression can also interfere with ED medication effectiveness. In such cases, counselling or addressing mental health concerns may be beneficial alongside medical treatment.

When to Consult Your Healthcare Provider

If Viagra hasn't worked after several attempts with proper timing and dosage, it's important to discuss this with your prescriber. They can review your medical history, current medications, and lifestyle factors to identify potential causes and alternative solutions.

Don't discontinue treatment without medical guidance, as adjustments to dosage, timing, or switching to alternative medications might resolve the issue. Your healthcare provider may also investigate underlying causes that could be affecting treatment effectiveness.

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.
