Both medications are PDE5 inhibitors but work at different speeds and durations. Viagra (sildenafil) has been trusted for over 25 years, whilst Spedra (avanafil) offers faster onset. EverydayMeds provides both branded Viagra and generic sildenafil options, allowing patients to choose based on preference and budget during checkout.

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.

Understanding Your ED Treatment Options

How Viagra and Spedra Compare

Both Viagra (sildenafil) and Spedra (avanafil) belong to the same class of medications called PDE5 inhibitors. They work by increasing blood flow to the penis during sexual arousal. However, their onset times and characteristics differ. Viagra has been extensively studied since 1998 and remains the most recognised ED treatment globally. Spedra, introduced more recently, was developed to address some limitations of earlier PDE5 inhibitors.

Onset and Duration Differences

The key difference lies in how quickly each medication begins working. Viagra typically takes 30-60 minutes to become effective, though this may be delayed by fatty meals. Spedra may work within 15-30 minutes and appears less affected by food intake. Both medications can remain effective for approximately 4-6 hours, though this doesn't mean an erection lasts this duration. The effects simply mean the medication remains available to work when sexual stimulation occurs.

Choosing Between Branded and Generic Options

At EverydayMeds, patients can choose between branded Viagra or generic sildenafil during checkout. Generic sildenafil contains the identical active ingredient as Viagra but costs significantly less. Clinical studies demonstrate generic sildenafil provides equivalent effectiveness and safety profiles. This choice allows patients to select based on personal preference and budget considerations whilst receiving the same therapeutic benefits.

Dosage Considerations

Both medications are available in similar strengths. Viagra and sildenafil come in 25mg, 50mg, and 100mg tablets, with 50mg being the typical starting dose. Spedra is available in 50mg, 100mg, and 200mg strengths. Dosing should always be determined by a healthcare professional following clinical assessment. Neither medication should be taken more than once per 24-hour period.

Side Effects and Suitability

Common side effects for both medications may include headache, facial flushing, indigestion, and nasal congestion. Most side effects are mild and temporary. However, both medications have important contraindications. They must not be taken with nitrate medications or by men with certain heart conditions. A thorough medical assessment helps determine suitability and identifies any potential interactions with current medications.

Making Your Decision

The choice between Viagra and Spedra often comes down to personal preference regarding onset time and individual response. Some men prefer Viagra's established track record and the option to choose generic sildenafil for cost savings. Others may prefer Spedra's potentially faster onset. Both require a prescription following consultation with a UK-licensed prescriber who can assess which option may be most suitable based on your individual circumstances and medical history.

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.
