Viagra vs Spedra: Comparing ED Treatment Options

When considering erectile dysfunction treatment, Viagra (sildenafil) and Spedra (avanafil) are two popular prescription options. Both are PDE5 inhibitors that can help improve blood flow, but they differ in onset time, duration, and side effect profiles. Understanding these differences can help you make an informed choice about which treatment may be more suitable for your needs and lifestyle.

  • Viagra typically takes 30-60 minutes to work, while Spedra can work in 15-30 minutes
  • Both medications last approximately 4-6 hours but don't cause prolonged erections
  • Spedra may have fewer food interactions compared to Viagra
  • Generic sildenafil offers the same benefits as branded 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.

Detailed Comparison: Viagra vs Spedra for ED Treatment

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 helps increase blood flow to the penis during sexual arousal. It's important to understand that neither medication causes automatic erections - sexual stimulation is still required for them to be effective.

Speed of Action: A Key Difference

One of the main differences between these treatments is how quickly they begin working. Viagra typically takes 30-60 minutes to become effective, while Spedra may work faster, often within 15-30 minutes. This quicker onset can make Spedra more suitable for spontaneous intimacy. However, food, particularly fatty meals, can delay the onset of action for Viagra more than for Spedra.

Duration and Effectiveness

Both medications can remain effective for approximately 4-6 hours, though this doesn't mean erections last this entire duration. The actual duration of effect can vary between individuals based on factors including age, overall health, other medications, and dosage. Clinical studies have shown both treatments to be effective for many men with erectile dysfunction when used as prescribed.

Side Effects and Tolerability

Common side effects for both medications may include headaches, flushing, indigestion, and nasal congestion. Some men find that Spedra causes fewer side effects, particularly regarding vision-related issues that can occasionally occur with sildenafil. However, individual responses vary, and what works well for one person may not be ideal for another.

Dosage Options and Flexibility

Viagra is 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 health assessment and may adjust it based on effectiveness and any side effects experienced.

Cost Considerations

When considering treatment costs, it's worth noting that generic sildenafil offers the same active ingredient as branded Viagra at a significantly lower price point. At EverydayMeds, patients can choose between branded Viagra or generic sildenafil during checkout, allowing you to select the option that best fits your budget while receiving the same therapeutic benefits.

Choosing Between Viagra and Spedra

The choice between these treatments often comes down to personal preference and individual response. Some men prefer Spedra for its faster onset and potentially fewer food interactions, while others find Viagra perfectly suitable for their needs, especially when opting for the more economical generic sildenafil version. Your healthcare provider can help determine which option may be most appropriate based on your medical history, current medications, and lifestyle factors.

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.
