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: The Original ED Treatment

Viagra revolutionised erectile dysfunction treatment when launched in 1998. This prescription medication contains sildenafil citrate as its active ingredient, which works by inhibiting the PDE5 enzyme to increase blood flow to the penis during sexual arousal. Viagra typically begins working within 30-60 minutes and remains effective for 4-6 hours, though this doesn't mean erections last this duration.

The medication requires sexual stimulation to work effectively and must be prescribed following clinical assessment by a qualified prescriber. Viagra is available in three strengths: 25mg, 50mg, and 100mg tablets, with 50mg being the standard starting dose for most men.

Generic Sildenafil: The Most Popular Alternative

Generic sildenafil represents the most widely chosen alternative to branded Viagra. Containing the exact same active ingredient in identical concentrations, generic sildenafil offers equivalent effectiveness, safety profile, and side effects as Viagra but at a substantially lower cost.

This makes generic sildenafil particularly attractive for long-term treatment, as the savings can be significant over time. The medication undergoes the same rigorous quality controls and regulatory approval as branded products, ensuring consistent therapeutic outcomes. At EverydayMeds, patients can choose between branded Viagra or generic sildenafil at checkout, allowing personal preference to guide their decision.

Cialis (Tadalafil): The Weekend Alternative

Cialis contains tadalafil and offers a distinctly different profile from Viagra. With effects lasting up to 36 hours, Cialis has earned the nickname "the weekend pill" due to its extended duration. This longer window can reduce performance pressure and allow for more spontaneous intimacy.

Cialis also offers a daily low-dose option (2.5mg or 5mg), providing continuous treatment that doesn't require timing around sexual activity. Some men find Cialis causes fewer visual side effects compared to sildenafil-based treatments, though individual responses vary considerably.

Levitra (Vardenafil): The Sensitive Option

Vardenafil, available as branded Levitra or generic alternatives, may be suitable for men who experience side effects with other PDE5 inhibitors. It has a similar onset time to Viagra but may be less affected by food consumption, potentially offering more flexibility around meals.

Some clinical studies suggest vardenafil may be effective for men with diabetes who haven't responded well to other treatments, though individual results vary and proper medical assessment remains essential.

Viagra Connect: Over-the-Counter Accessibility

Viagra Connect provides 50mg sildenafil without prescription requirement, following consultation with a qualified pharmacist. This option suits men who meet specific criteria and aren't taking medications that could cause dangerous interactions.

However, prescription options offer greater flexibility with 25mg and 100mg strengths available, plus comprehensive medical review. The choice between over-the-counter and prescription routes depends on individual circumstances and medical complexity.

Choosing the Right Alternative

Selecting the most appropriate option depends on multiple factors including lifestyle preferences, medical history, current medications, and individual response patterns. Men seeking immediate cost savings might prefer generic sildenafil, whilst those wanting extended duration may favour tadalafil-based treatments.

Timing preferences also influence choice - some prefer taking medication just before sexual activity, whilst others prefer daily dosing that provides constant readiness. Side effect profiles can vary between individuals, so what works well for one person may not suit another.

Dosage Flexibility Across Alternatives

Different alternatives offer varying dosage options. Sildenafil (including Viagra) provides 25mg, 50mg, and 100mg strengths, allowing precise dose adjustment based on effectiveness and tolerability. Tadalafil offers both on-demand dosing (10mg, 20mg) and daily options (2.5mg, 5mg).

Starting with lower doses helps identify the minimum effective amount whilst reducing side effect risk. Prescribers can adjust dosages based on treatment response, ensuring optimal outcomes for each individual.

Safety Considerations Across All Alternatives

All PDE5 inhibitors share similar contraindications, particularly the dangerous interaction with nitrate medications used for heart conditions. They also require caution in men with cardiovascular disease, severe liver impairment, or recent heart attack or stroke.

Each alternative requires proper medical assessment before prescribing, ensuring treatments are safe and appropriate for individual circumstances. Regular review helps monitor effectiveness and identify any emerging 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.
