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.

Comparing Viagra and Tadalafil for ED Treatment

How Viagra and Tadalafil Work

Both British Viagra and Tadalafil belong to a 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 effectiveness. The key difference lies in their duration of action and timing requirements.

Timing and Duration Differences

Viagra (sildenafil) typically begins working within 30-60 minutes and remains effective for 4-6 hours. This makes it suitable for planned sexual activity. Tadalafil has a longer onset time of 30 minutes to 2 hours but can remain effective for up to 36 hours, earning it the nickname "the weekend pill". This extended duration may offer more spontaneity in timing.

Dosage Options and Flexibility

British Viagra is available in 25mg, 50mg, and 100mg tablets, with 50mg being the typical starting dose. Tadalafil comes in 2.5mg, 5mg, 10mg, and 20mg strengths. Tadalafil can be taken as needed or daily at lower doses (2.5mg-5mg), whilst Viagra is typically taken only when needed. Both medications should not be taken more than once in 24 hours.

Food and Alcohol Considerations

Viagra's effectiveness may be reduced by fatty meals, which can delay absorption. Tadalafil is less affected by food intake, making it more flexible with meal timing. Both medications can interact with alcohol, potentially increasing side effects like dizziness or low blood pressure. Moderate alcohol consumption is generally acceptable, but excessive drinking should be avoided.

Side Effects Comparison

Both medications share similar side effects, including headaches, flushing, indigestion, and nasal congestion. Viagra may be more likely to cause visual disturbances, whilst Tadalafil might cause back pain or muscle aches. These side effects are typically mild and temporary. Serious side effects are rare but require immediate medical attention.

Cost Considerations

Generic sildenafil offers the same active ingredient as branded Viagra at a significantly lower cost. EverydayMeds provides both options, allowing patients to choose between branded Viagra and generic sildenafil based on their preferences and budget. Tadalafil generics are also available and cost-effective compared to branded versions.

Lifestyle Suitability

Your choice between Viagra and Tadalafil may depend on your lifestyle preferences. If you prefer planned intimacy, Viagra's shorter duration might be suitable. For those wanting more spontaneity and flexibility, Tadalafil's longer window of effectiveness could be advantageous. Both require consultation with a UK-licensed prescriber to ensure safety and suitability.

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.
