Viagra vs Spedra: Comparing ED Treatments

When choosing between Viagra and Spedra for erectile dysfunction, understanding their differences helps make an informed decision. Both are PDE5 inhibitors that work by increasing blood flow to the penis during sexual arousal. While Viagra has been trusted for over 25 years, Spedra offers faster onset and potentially fewer side effects. EverydayMeds provides both branded Viagra and generic sildenafil options following clinical assessment by UK-licensed prescribers, helping you find the most suitable and cost-effective treatment.

  • Spedra typically works within 15-30 minutes compared to Viagra's 30-60 minutes
  • Both medications can last 4-6 hours and require sexual stimulation to work
  • Generic sildenafil offers the same effectiveness as branded Viagra at lower cost
  • Side effects and interactions differ slightly between the two treatments

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: Effectiveness and Timing

How Viagra and Spedra Work

Both Viagra (sildenafil) and Spedra (avanafil) are PDE5 inhibitors that work by blocking the enzyme phosphodiesterase type 5. This action increases blood flow to the penis when sexually aroused, helping achieve and maintain an erection. Neither medication causes automatic erections - sexual stimulation remains necessary for both to be effective.

Speed of Action and Duration

Spedra generally works faster than Viagra, with effects typically beginning within 15-30 minutes compared to Viagra's 30-60 minutes onset time. This faster action can be advantageous for spontaneous intimacy. Both medications can remain effective for 4-6 hours, though this doesn't mean an erection lasts this duration - effects occur only during sexual arousal.

Food and Alcohol Interactions

Spedra is less affected by food intake than Viagra. Fatty meals can significantly delay Viagra's onset, whilst Spedra maintains more consistent effectiveness regardless of recent food consumption. Both medications can be affected by excessive alcohol consumption, which may reduce effectiveness and increase side effect risk.

Side Effects Comparison

Common side effects for both include headaches, facial flushing, and nasal congestion. Viagra may be more likely to cause visual disturbances, whilst Spedra potentially causes fewer side effects overall. Both can cause dizziness or back pain in some users. Serious side effects are rare but require immediate medical attention.

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. Dosages can be adjusted based on effectiveness and tolerability, with maximum one dose per 24-hour period for both medications.

Cost Considerations

Branded Viagra tends to be more expensive than Spedra, though generic sildenafil offers significant cost savings whilst maintaining identical effectiveness to branded Viagra. At EverydayMeds, patients can choose between branded Viagra or generic sildenafil during checkout, allowing cost-conscious decisions without compromising treatment quality.

Which Treatment Suits You?

Choice between Viagra and Spedra often depends on individual preferences and medical factors. Spedra may suit those wanting faster onset or experiencing visual side effects with Viagra. Viagra, particularly generic sildenafil, may be preferred for its proven track record and cost-effectiveness. Both require prescription following clinical assessment to ensure suitability and safety.

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.
