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.

Viagra vs Tadalafil: Which ED Treatment Is Right?

Understanding the Key Differences

When comparing where you can buy Viagra versus tadalafil, it's important to understand how these ED medications differ. Viagra contains sildenafil citrate and typically works within 30-60 minutes, with effects lasting 4-6 hours. Tadalafil, on the other hand, may take 30 minutes to 2 hours to work but can remain effective for up to 36 hours, earning it the nickname "the weekend pill".

Viagra and Sildenafil Options

At EverydayMeds, patients can choose between branded Viagra or generic sildenafil at checkout. Both contain the same active ingredient (sildenafil citrate) and work identically, but generic sildenafil offers significant cost savings. This choice allows you to access effective ED treatment while managing your healthcare budget according to your preferences.

How Each Medication Works

Both Viagra and tadalafil are PDE5 inhibitors that increase blood flow to the penis during sexual arousal. Neither medication causes automatic erections - sexual stimulation is still required. Viagra's shorter duration may suit men who prefer more spontaneous intimacy, whilst tadalafil's longer window may benefit those who prefer not to time their medication as precisely.

Dosage and Administration Differences

Viagra and sildenafil are available in 25mg, 50mg, and 100mg tablets, with 50mg being the typical starting dose. Tadalafil comes in 2.5mg, 5mg, 10mg, and 20mg strengths. For on-demand use, tadalafil is usually prescribed as 10mg or 20mg. Both medications should be taken no more than once per 24 hours.

Choosing Based on Lifestyle

Your choice between Viagra and tadalafil may depend on your lifestyle and preferences. Men who prefer to take medication closer to sexual activity might favour Viagra's more predictable timing. Those who value spontaneity over several days might prefer tadalafil's longer duration. Food can delay Viagra's onset, particularly fatty meals, whilst tadalafil is less affected by food intake.

Side Effects and Considerations

Both medications share similar side effects, including headache, flushing, nasal congestion, and indigestion. However, some men may tolerate one medication better than another. Neither should be taken with nitrate medications or by men with certain cardiovascular conditions. A clinical assessment with our UK-licensed prescribers ensures safe, appropriate treatment.

Getting Your ED Treatment

EverydayMeds provides convenient access to both Viagra and tadalafil through our regulated online pharmacy service. After completing a clinical questionnaire reviewed by our UK-licensed prescribers, eligible patients receive genuine prescription medications with discreet home delivery. Our service ensures you receive authentic treatments whilst maintaining complete confidentiality.

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.
