Viagra vs Spedra: Which ED Treatment is Right for You?

When choosing between Viagra and Spedra for erectile dysfunction treatment, understanding their differences helps make an informed decision. Both are effective PDE5 inhibitors that work by increasing blood flow to the penis during sexual arousal. Viagra (sildenafil) has been trusted for over 25 years, whilst Spedra (avanafil) is a newer option with faster onset. EverydayMeds offers both branded Viagra and generic sildenafil, allowing you to choose the most suitable option for your needs and budget.

  • Viagra typically takes 30-60 minutes to work and lasts 4-6 hours
  • Spedra may work faster (15-30 minutes) but has similar duration
  • Generic sildenafil offers the same active ingredient as Viagra at lower cost
  • Both require sexual stimulation to be effective and need prescription assessment

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.

Comparing Effectiveness: Viagra vs Spedra for ED

How Viagra and Spedra 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 you're sexually aroused. Neither medication causes automatic erections - sexual stimulation is still required for effectiveness.

Speed of Action and Duration

One key difference between these treatments lies in their onset time. Viagra typically begins working within 30-60 minutes of taking the tablet, with effects lasting 4-6 hours. Spedra may work slightly faster, potentially taking effect within 15-30 minutes, though it has a similar duration of action. Food, particularly fatty meals, can delay the onset of both medications.

Effectiveness Comparison

Clinical studies suggest both medications are highly effective for treating erectile dysfunction, with success rates often exceeding 70% in suitable patients. The choice between them often comes down to individual response, timing preferences, and tolerability. Some men may find one works better for their particular circumstances than the other.

Dosage Options

Viagra is available in 25mg, 50mg, and 100mg strengths, with 50mg being the typical starting dose. Spedra comes in 50mg, 100mg, and 200mg tablets, usually starting at 100mg. Both medications should only be taken once per 24-hour period, approximately 30-60 minutes before sexual activity.

Cost Considerations

Generic sildenafil offers significant cost savings compared to branded Viagra whilst containing the same active ingredient. At EverydayMeds, patients can choose between branded Viagra or generic sildenafil at checkout, allowing you to balance effectiveness with affordability. Spedra, being a newer medication, typically costs more than both branded Viagra and generic sildenafil.

Side Effects and Tolerability

Both medications may cause similar side effects including headaches, flushing, indigestion, and nasal congestion. Some patients report that Spedra causes fewer side effects, though individual responses vary. Neither should be taken with nitrate medications due to dangerous interactions that can cause severely low blood pressure.

Choosing the Right Treatment

The best choice depends on your individual needs, medical history, and preferences. Factors to consider include how quickly you need the medication to work, duration requirements, cost considerations, and any side effects experienced. A clinical assessment with a UK-licensed prescriber will help determine which option is most suitable for your 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.
