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.

Viagra Dosage Strengths: Complete Comparison Guide

Understanding Viagra Strength Options

When considering erectile dysfunction treatment, understanding the different Viagra strengths available can help optimise your treatment experience. Viagra contains sildenafil citrate as its active ingredient and is manufactured by Pfizer. The same active ingredient is available as generic sildenafil, which offers identical therapeutic effects at a lower cost point.

25mg Viagra: Lower Strength Option

The 25mg strength typically serves as a reduced dose for men who may experience side effects with higher strengths or those taking certain medications that could interact with sildenafil. This strength may be recommended for men over 65, those with liver or kidney problems, or patients taking medications like alpha-blockers. Whilst 25mg may be effective for some men, others might find this strength insufficient for their needs.

50mg Viagra: Standard Starting Dose

The 50mg tablet represents the recommended starting dose for most men with erectile dysfunction. Clinical studies demonstrate that 50mg provides effective results for the majority of patients whilst maintaining a good tolerability profile. This strength typically takes effect within 30-60 minutes of administration and may remain effective for 4-6 hours. Many men find 50mg provides the optimal balance between effectiveness and minimal side effects.

100mg Viagra: Maximum Strength

The 100mg strength represents the maximum recommended dose of sildenafil within a 24-hour period. This strength may be appropriate for men who don't achieve satisfactory results with 50mg, provided they tolerate the medication well. Healthcare providers may recommend increasing to 100mg after assessing the patient's response to lower doses. It's important to note that taking more than 100mg doesn't improve effectiveness but may increase the risk of side effects.

Branded Viagra vs Generic Sildenafil

EverydayMeds offers both branded Viagra and generic sildenafil options, allowing patients flexibility in their treatment choice. Both contain identical active ingredients and undergo rigorous quality standards. The primary difference lies in cost, with generic sildenafil offering significant savings whilst maintaining therapeutic equivalence. Patients can select their preferred option during the checkout process based on personal preference and budget considerations.

Dosage Timing and Administration

Regardless of strength chosen, Viagra should be taken approximately 30-60 minutes before anticipated sexual activity. The medication requires sexual stimulation to be effective and doesn't cause automatic erections. Large or fatty meals may delay the onset of action. Only one dose should be taken within any 24-hour period, and patients should follow their healthcare provider's specific dosing instructions.

Safety Considerations Across All Strengths

All Viagra strengths require prescription following consultation with a qualified healthcare provider. The medication isn't suitable for men taking nitrate medications, those with severe cardiovascular conditions, or individuals with certain medical contraindications. A comprehensive medical assessment ensures safe prescribing and identifies the most appropriate starting strength for each patient's individual 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.
