Viagra vs Spedra: Comparing ED Treatment Options

When considering ED treatment options, many men compare Viagra (sildenafil) with Spedra (avanafil). Both are PDE5 inhibitors that may help improve erectile function, but they differ in onset time, duration, and individual response rates. Understanding these differences can help you make an informed choice. EverydayMeds offers both branded Viagra and generic sildenafil options following online consultation with UK-licensed prescribers.

  • Viagra typically takes 30-60 minutes to work, while Spedra may work within 15-30 minutes
  • Both medications require sexual stimulation to be effective
  • Spedra may be less affected by food and alcohol consumption
  • Generic sildenafil provides 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.

Understanding the Key Differences Between These Treatments

How Viagra and Spedra Work

Both Viagra (sildenafil) and Spedra (avanafil) belong to a class of medications called PDE5 inhibitors. They work by increasing blood flow to the penis when sexually aroused, potentially helping men achieve and maintain an erection suitable for sexual activity. Neither medication causes automatic erections - sexual stimulation is still required for effectiveness.

Onset Time and Duration

One of the main differences between these treatments lies in their timing. Viagra typically begins working within 30-60 minutes of taking the tablet, with effects potentially lasting 4-6 hours. Spedra, however, may work more quickly, often within 15-30 minutes, though its duration is similar at around 4-6 hours. This faster onset time may make Spedra more suitable for spontaneous sexual activity.

Food and Alcohol Interactions

Viagra's effectiveness can be reduced when taken with large or fatty meals, which may delay absorption and onset time. Spedra appears to be less affected by food intake, making it potentially more convenient for some men. Both medications should be used cautiously with alcohol, as excessive drinking can impair erectile function and increase the risk of side effects like dizziness or low blood pressure.

Side Effects and Tolerability

Common side effects for both medications may include headaches, facial flushing, nasal congestion, and indigestion. Some men report that Spedra causes fewer side effects, particularly visual disturbances, which can occasionally occur with sildenafil. However, individual responses vary significantly, and what works best for one person may not be ideal for another.

Cost Considerations

Viagra, being the original branded medication, is typically more expensive than generic sildenafil, which contains the same active ingredient. At EverydayMeds, patients can choose between branded Viagra or generic sildenafil during checkout, allowing for cost-effective treatment without compromising on quality. Spedra, being a newer medication, is usually priced similarly to 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. The appropriate dose depends on individual response, tolerability, and medical history, which is why professional medical assessment is essential.

Who Might Benefit from Each Option

Men who prefer faster onset times and less food interaction might find Spedra more suitable for their lifestyle. Those seeking cost-effective treatment might prefer generic sildenafil, while others may prefer the established track record of branded Viagra. Some men who don't respond well to one medication may find better results with another, highlighting the importance of personalised treatment approaches.

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.
