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.

How Long Does Each Medication Last in Your System?

Viagra Duration and Onset

Viagra (sildenafil) typically remains effective for 4-6 hours after taking a dose. The medication usually begins working within 30-60 minutes, though this can vary depending on factors such as food intake, individual metabolism, and overall health. It's important to note that whilst the effects may last up to 6 hours, this doesn't mean you'll have an erection for this entire duration - sexual stimulation is still required throughout.

Spedra's Extended Duration

Spedra (avanafil) often provides a longer window of effectiveness, potentially lasting 6-12 hours in many users. One of Spedra's key advantages is its rapid onset time, typically working within 15-30 minutes of taking the tablet. This faster action can offer more spontaneity compared to Viagra's longer preparation time.

Factors Affecting Duration

Several factors can influence how long either medication lasts in your system. Age, overall health, liver function, and concurrent medications can all affect duration. Fatty meals can delay the onset of both medications, though Spedra is generally less affected by food than Viagra. Alcohol consumption may also reduce effectiveness and duration for both treatments.

Choosing Between Viagra and Spedra

The choice between these medications often comes down to personal preference and lifestyle factors. If you prefer a longer duration of action and faster onset, Spedra might be more suitable. However, Viagra has a longer track record and extensive clinical data supporting its use. At EverydayMeds, patients can choose between branded Viagra or generic sildenafil, with the generic option providing the same active ingredient at a lower cost.

Side Effects and Tolerability

Both medications can cause similar side effects, including headaches, facial flushing, and nasal congestion. Some users may find they tolerate one medication better than the other. Spedra may have a slightly lower incidence of visual disturbances compared to sildenafil, though serious side effects are rare with both medications when used appropriately.

Cost Considerations

Generic sildenafil typically offers significant cost savings compared to both branded Viagra and Spedra. The active ingredient and effectiveness remain identical to the branded version, making generic sildenafil an excellent value option for many patients. EverydayMeds provides both branded and generic options, allowing patients to make the choice that best suits their budget and preferences.

Making Your Decision

Consulting with a healthcare professional is essential when choosing between these treatments. They can assess your medical history, current medications, and individual circumstances to recommend the most appropriate option. Both Viagra and Spedra are prescription-only medicines that require proper medical assessment before use.

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.
