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

When choosing between Viagra and Spedra for erectile dysfunction, understanding their differences helps you make an informed decision. Both medications are effective PDE5 inhibitors that work by increasing blood flow to the penis during sexual stimulation. Viagra contains sildenafil and has been the gold standard for ED treatment for over 25 years. Spedra contains avanafil, a newer active ingredient that may work faster. At EverydayMeds, we offer both branded Viagra and generic sildenafil options following an online consultation with our UK-licensed prescribers.

  • Viagra typically takes 30-60 minutes to work, while Spedra may work in 15-30 minutes
  • Both medications can be effective for 4-6 hours after taking
  • Spedra may be less affected by food and alcohol consumption
  • Generic sildenafil offers the same active ingredient as Viagra at a 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.

How Do Viagra and Spedra Compare for Effectiveness?

Speed of Action: Spedra's Potential Advantage

One of the key differences between Viagra and Spedra lies in how quickly they may take effect. Viagra (sildenafil) typically begins working within 30-60 minutes of taking the tablet. Spedra (avanafil) may work faster, with some men experiencing effects within 15-30 minutes. This faster onset could provide more spontaneity for intimate moments. However, individual responses vary, and both medications require sexual stimulation to be effective.

Duration of Effects

Both Viagra and Spedra can remain effective for approximately 4-6 hours after taking. This doesn't mean you'll have an erection for this entire period - rather, you may find it easier to achieve and maintain an erection when sexually aroused during this timeframe. The effects gradually diminish as your body processes the medication.

Food and Alcohol Interactions

Spedra may have an advantage when it comes to food interactions. Large or fatty meals can significantly delay how quickly Viagra takes effect, sometimes by an hour or more. Spedra appears to be less affected by food consumption, though it's still recommended to avoid excessive alcohol with both medications as this can reduce their effectiveness and increase the risk of side effects like dizziness.

Side Effects Comparison

Both medications belong to the same class of drugs (PDE5 inhibitors) and share similar potential side effects, including headaches, facial flushing, indigestion, and nasal congestion. Some studies suggest Spedra may cause fewer visual disturbances compared to sildenafil, though serious side effects are rare with both medications when used appropriately under medical supervision.

Cost Considerations

Viagra remains one of the most expensive branded ED treatments. At EverydayMeds, patients can choose between branded Viagra or generic sildenafil at checkout - both contain the same active ingredient (sildenafil citrate) but generic versions typically cost significantly less. Spedra, being a newer medication, is also positioned at a premium price point. For many men, generic sildenafil provides excellent value while delivering the same therapeutic benefits as branded Viagra.

Dosage Options

Viagra and generic sildenafil are available in 25mg, 50mg, and 100mg strengths, with 50mg being the typical starting dose. Spedra comes in 50mg, 100mg, and 200mg tablets. Your prescriber will determine the most appropriate starting dose based on your medical history, other medications, and individual response to treatment.

Which Medication Might Suit You?

The choice between Viagra and Spedra often comes down to personal preference and individual response. If faster onset is important to you, Spedra might be worth considering. If you prefer a well-established treatment with extensive clinical data and the option to choose between branded and generic versions, Viagra or sildenafil could be more suitable. Both medications require a prescription following consultation with a qualified healthcare provider who can assess your medical history and current medications to ensure safe use.

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.
