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: Sildenafil 50mg vs Spedra

How Both Medications Work

Sildenafil 50mg and Spedra both 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 during sexual arousal. Neither medication causes automatic erections - sexual stimulation is still required for both to work effectively.

Onset Time and Duration

The main difference between sildenafil 50mg and Spedra lies in their onset time. Sildenafil typically begins working within 30-60 minutes of taking, whilst Spedra may work slightly faster, often within 15-30 minutes. Both medications can provide effects lasting 4-6 hours, though this doesn't mean an erection will last this entire time. Food intake, particularly fatty meals, can delay the onset of both medications.

Effectiveness and Success Rates

Clinical studies suggest both sildenafil and Spedra have similar effectiveness rates for treating erectile dysfunction. The 50mg dose of sildenafil is the standard starting dose and proves effective for many men. Spedra is available in 50mg, 100mg, and 200mg strengths. Both medications can be adjusted based on individual response and tolerability.

Side Effects Profile

Both medications share similar potential side effects, including headache, flushing, nasal congestion, and indigestion. Some users report that Spedra may cause fewer side effects due to its more selective action, though individual responses vary. Both medications have the same contraindications, particularly with nitrate medications used for heart conditions.

Cost Considerations

Generic sildenafil offers significant cost savings compared to branded alternatives like Spedra. At EverydayMeds, patients can choose between branded Viagra or generic sildenafil at checkout, allowing flexibility based on budget and preference. The active ingredient and effectiveness remain the same whether choosing branded or generic options.

Choosing the Right Option

The choice between sildenafil 50mg and Spedra often comes down to individual factors such as desired onset time, cost considerations, and personal response. Those prioritising faster action might prefer Spedra, whilst those seeking cost-effective treatment may opt for generic sildenafil. Both require prescription following consultation with a UK-licensed prescriber who can assess suitability based on medical history and current medications.

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.
