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 UK Patients

Active Ingredients and How They Work

Viagra contains sildenafil citrate, while Spedra contains avanafil. Both are PDE5 inhibitors that work by increasing blood flow to the penis when sexually aroused. Neither medication causes automatic erections - sexual stimulation is still required for effectiveness. At EverydayMeds, patients can choose between branded Viagra or generic sildenafil, which contains the same active ingredient as Viagra but at a reduced cost.

Onset Time and Duration

One of the key differences between these treatments is timing. Viagra typically takes 30-60 minutes to become effective, with peak effects occurring 1-2 hours after taking. Spedra generally works faster, often becoming effective within 15-30 minutes of consumption. Both medications can remain effective for 4-6 hours, though this doesn't mean an erection will last this entire duration.

Food and Alcohol Interactions

Spedra has a notable advantage regarding food interactions. While Viagra's effectiveness may be delayed by fatty meals, Spedra is less affected by food consumption, making it more convenient for spontaneous use. However, both medications can be influenced by excessive alcohol consumption, which may reduce their effectiveness and increase the risk of side effects.

Side Effects and Tolerability

Both treatments share similar side effect profiles, including potential headaches, facial flushing, nasal congestion, and indigestion. However, some patients report that Spedra may cause fewer visual disturbances compared to sildenafil. Individual responses vary, and what works best for one person may differ for another. Your prescribing clinician can help determine which option might be most suitable based on your medical history.

Dosage Options and Flexibility

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, with 100mg as the standard starting dose. Both treatments should only be taken once per 24-hour period, and dosages can be adjusted based on effectiveness and tolerability under medical supervision.

Cost Considerations

Generic sildenafil represents excellent value for money, providing the same active ingredient as branded Viagra at a significantly lower cost. This makes treatment more accessible for long-term use. Spedra, being a newer medication, typically costs more than both Viagra and generic sildenafil. EverydayMeds offers transparent pricing for all options, allowing patients to make informed decisions about their treatment.

Prescription Requirements

Both Viagra and Spedra are prescription-only medicines in the UK, requiring a consultation with a qualified prescriber. EverydayMeds provides convenient online consultations with UK-licensed clinicians who can assess your suitability for either treatment. The clinical assessment considers your medical history, current medications, and overall health to ensure safe and appropriate prescribing.

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.
