Viagra vs Spedra: Comparing ED Treatment Options

When choosing between Viagra and Spedra for erectile dysfunction treatment, understanding their differences helps inform your decision. Both are effective PDE5 inhibitors but work at different speeds and durations. Viagra contains sildenafil and has been trusted for over 25 years, whilst Spedra contains avanafil and offers faster onset. At EverydayMeds, we provide access to both branded Viagra and cost-effective sildenafil generic alternatives following an online consultation with UK-licensed prescribers.

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.

Comparing Viagra and Spedra: Key Differences

How Viagra and Spedra Work

Both Viagra (sildenafil) and Spedra (avanafil) belong to the same class of medications called PDE5 inhibitors. They work by blocking the phosphodiesterase type 5 enzyme, which increases blood flow to the penis when sexually aroused. Neither medication causes automatic erections - sexual stimulation is still required for effectiveness. The key difference lies in their onset speed and how they interact with food.

Onset Time and Duration

Viagra typically begins working within 30-60 minutes of taking the tablet, with effects lasting 4-6 hours. Food, particularly fatty meals, can delay its onset. Spedra offers a faster onset time of approximately 15-30 minutes and is less affected by food consumption. Both medications maintain similar duration of action, though individual responses may vary. The faster onset of Spedra can provide more spontaneity, whilst Viagra's longer track record offers proven reliability.

Available Dosages and Flexibility

Viagra is available in 25mg, 50mg, and 100mg tablets, with 50mg being the typical starting dose. Spedra comes in 50mg, 100mg, and 200mg strengths, with 100mg as the standard initial dose. Both can be adjusted based on effectiveness and tolerability during follow-up consultations. Maximum dosing for both medications is once per 24-hour period.

Cost Considerations and Generic Options

Branded Viagra tends to be more expensive than Spedra, though costs vary between suppliers. However, generic sildenafil offers the same active ingredient as Viagra at significantly lower cost. At EverydayMeds, patients can choose between branded Viagra or generic sildenafil during checkout, providing flexibility to balance budget with personal preference. Generic sildenafil contains identical active ingredients to branded Viagra, ensuring equivalent therapeutic benefits.

Side Effects and Tolerability

Both medications share similar side effect profiles, including potential headaches, flushing, nasal congestion, and digestive upset. Some men find one medication better tolerated than the other, though this varies individually. Spedra may have slightly fewer visual disturbances compared to Viagra, whilst both carry similar cardiovascular considerations. Serious side effects are rare but require immediate medical attention.

Eligibility and Contraindications

Both Viagra and Spedra require prescription following clinical assessment by UK-licensed prescribers. Neither should be taken with nitrate medications (GTN spray, isosorbide) due to dangerous blood pressure interactions. Men with severe heart disease, recent heart attack or stroke, or severe liver problems may not be suitable candidates. Online consultations assess medical history, current medications, and cardiovascular health before prescribing.

Making Your Choice

The decision between Viagra and Spedra often depends on personal priorities. If faster onset and food flexibility matter most, Spedra might be preferable. For those prioritising cost-effectiveness, generic sildenafil provides Viagra's benefits at lower expense. Men seeking the reassurance of the most established treatment might prefer branded Viagra. Many patients try both options to determine personal preference, as effectiveness can vary individually.

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.
