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 Effectiveness

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 during sexual arousal. Neither medication causes automatic erections - sexual stimulation is still required for effectiveness.

Onset Time and Duration

One of the key differences between these treatments lies in their timing. Viagra typically begins working within 30-60 minutes of taking, 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.

The faster onset time of Spedra can offer more spontaneity for some men, though both medications require some planning ahead. Individual responses can vary, and what works best may differ from person to person.

Food Interactions

Viagra's effectiveness can be delayed by food intake, particularly fatty meals, which may slow absorption. Spedra appears to be less affected by food, potentially making it more convenient for some users. However, both medications can be taken with or without food.

Effectiveness Rates

Clinical studies suggest both medications are effective for treating erectile dysfunction, with success rates typically ranging from 60-85% depending on the underlying cause and severity of ED. The "most effective" treatment often depends on individual factors including:

Age and overall health status, severity of erectile dysfunction, presence of other medical conditions like diabetes or cardiovascular disease, current medications and potential interactions, lifestyle factors and personal preferences.

Cost Considerations

While Spedra is only available as a branded medication, Viagra is available in both branded and generic (sildenafil) forms. Generic sildenafil contains the same active ingredient as branded Viagra but at a significantly lower cost, making it an attractive option for many patients.

At EverydayMeds, patients can choose between branded Viagra or generic sildenafil during checkout, allowing for flexible treatment options that suit different budgets and preferences.

Side Effects Profile

Both medications share similar potential side effects, including headache, flushing, nasal congestion, and indigestion. Some men may find they tolerate one medication better than another. Common side effects are usually mild and temporary.

Choosing the Right Treatment

The most effective ED treatment varies between individuals. Factors to consider include your lifestyle, timing preferences, budget, and how you respond to different medications. Some men may find Spedra's faster onset suits their needs, while others prefer the well-established track record and cost-effectiveness of Viagra or generic sildenafil.

A consultation with a healthcare professional can help determine which treatment might be most suitable for your specific situation. EverydayMeds offers confidential online consultations with UK-licensed prescribers who can assess your individual needs and recommend appropriate treatment options.

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.
