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 Viagra Dosage Options and Effectiveness

Viagra 25mg: Lower Strength Option

Viagra 25mg tablets represent the lowest available strength and may be suitable for men who experience side effects with higher doses or those taking certain medications. This dose is often recommended for older patients or those with underlying health conditions that might affect how the medication is processed. Whilst 25mg can be effective for some men, it may not provide sufficient improvement for moderate to severe erectile dysfunction. The reduced strength typically results in fewer side effects, making it an appropriate starting point for those concerned about tolerability.

Viagra 50mg: Standard Starting Dose

The 50mg strength serves as the recommended starting dose for most men seeking erectile dysfunction treatment. Clinical studies demonstrate that this dose provides an optimal balance between effectiveness and tolerability for the majority of patients. Most men find 50mg sufficient to achieve satisfactory results when taken approximately one hour before sexual activity. Healthcare providers typically prescribe this strength initially, adjusting up or down based on individual response and any side effects experienced.

Viagra 100mg: Maximum Strength Treatment

Viagra 100mg represents the highest available dose and is typically prescribed when lower strengths prove insufficient. This maximum strength may be appropriate for men with more severe erectile dysfunction or those who have not achieved desired results with 50mg. However, the increased dose also carries a higher likelihood of side effects, including headaches, facial flushing, and nasal congestion. Healthcare providers carefully evaluate whether the potential benefits justify the increased risk profile before prescribing the 100mg strength.

Branded Viagra vs Generic Sildenafil

Both branded Viagra and generic sildenafil contain identical active ingredients and undergo rigorous testing to ensure equivalent effectiveness. The primary difference lies in cost, with generic sildenafil typically offering significant savings whilst providing the same therapeutic benefits. At EverydayMeds, patients can choose between branded and generic options during checkout, allowing personal preference and budget considerations to guide their decision. Both options require the same clinical assessment and are available in identical strengths.

Factors Affecting Dosage Selection

Several factors influence the appropriate Viagra strength, including age, overall health status, severity of erectile dysfunction, and concurrent medications. Cardiovascular health plays a particularly important role, as sildenafil can interact with heart medications and affect blood pressure. Liver and kidney function also impact how the body processes the medication, potentially requiring dose adjustments. Your prescriber will evaluate these factors during the clinical assessment to recommend the most appropriate starting dose.

Safety Considerations and Monitoring

Regardless of strength chosen, Viagra should only be taken once per 24-hour period and requires sexual stimulation to be effective. The medication begins working within 30-60 minutes and effects may last up to four hours. Taking Viagra with large or fatty meals can delay onset of action. Regular monitoring helps ensure the chosen strength remains appropriate, with adjustments made based on effectiveness and any side effects experienced during treatment.

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.
