Viagra UK vs Spedra: Comparing ED Treatments

Choosing between Viagra and Spedra for erectile dysfunction treatment requires understanding how these medications differ. Both are effective PDE5 inhibitors available on prescription in the UK, but they work at different speeds and have varying duration profiles. This comparison examines the key differences between sildenafil (Viagra) and avanafil (Spedra) to help you make an informed decision. EverydayMeds offers both branded Viagra and cost-effective generic sildenafil following online consultation.

  • Viagra contains sildenafil and typically works within 30-60 minutes
  • Spedra contains avanafil and may work faster, within 15-30 minutes
  • Both require sexual stimulation to be effective and last 4-6 hours
  • Generic sildenafil offers the same active ingredient as Viagra at lower cost

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.

Detailed Comparison: Sildenafil vs Avanafil

How These ED Medications Work

Both Viagra (sildenafil) and Spedra (avanafil) belong to a class of medications called PDE5 inhibitors. They work by blocking the phosphodiesterase type 5 enzyme, which increases blood flow to the penis when sexually aroused. Neither medication causes automatic erections - sexual stimulation is still required for effectiveness.

Speed of Action and Duration

The main difference between these treatments lies in their onset times. Viagra containing sildenafil typically becomes effective within 30-60 minutes of taking the tablet. Spedra, containing avanafil, may work slightly faster, potentially within 15-30 minutes for some patients.

Both medications can remain effective for 4-6 hours, though this doesn't mean an erection will last this long. The duration refers to the window during which the medication can help achieve erections when sexually stimulated.

Food and Alcohol Interactions

Spedra generally shows less interaction with food compared to Viagra. High-fat meals can delay Viagra's effectiveness, whilst Spedra may be less affected by food intake. Both medications can be affected by excessive alcohol consumption, which may reduce their effectiveness and increase the risk of side effects like dizziness or low blood pressure.

Dosage Options Available

Viagra and generic sildenafil are available in 25mg, 50mg, and 100mg strengths. The typical starting dose is 50mg, which can be adjusted based on effectiveness and tolerability. Spedra comes in 50mg, 100mg, and 200mg tablets, with 100mg being the usual starting dose.

Cost Considerations

Viagra is the original branded version of sildenafil, whilst generic sildenafil contains the same active ingredient at a lower cost. At EverydayMeds, patients can choose between branded Viagra or generic sildenafil during checkout after completing their consultation. This flexibility allows patients to select based on their preferences and budget whilst receiving the same clinical benefits.

Side Effects Profile

Both medications share similar common side effects, including headaches, facial flushing, nasal congestion, and indigestion. Some studies suggest Spedra may have a slightly lower incidence of certain side effects, but individual responses vary significantly.

Eligibility and Consultation Process

Both treatments require consultation with a UK-licensed prescriber to ensure they're suitable for your health status and current medications. Patients with heart conditions, those taking nitrate medications, or with certain medical histories may not be suitable candidates for either treatment.

The consultation process at EverydayMeds evaluates your medical history, current medications, and overall cardiovascular health to determine the most appropriate treatment option.

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.
