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: Key Timing Differences

When to Take Viagra: Optimal Timing

Viagra should be taken approximately 30-60 minutes before anticipated sexual activity. The medication reaches peak effectiveness within one hour of consumption, making timing crucial for optimal results. Unlike tadalafil, which offers a longer window of effectiveness, Viagra requires more precise planning.

Duration of Action: Viagra vs Tadalafil

Viagra's effects typically last 4-6 hours, during which time you may find it easier to achieve and maintain erections when sexually aroused. Tadalafil, conversely, can remain effective for up to 36 hours, earning it the nickname "the weekend pill." This extended duration means tadalafil offers greater spontaneity, whilst Viagra provides more predictable, shorter-term effects.

Food Considerations

Heavy or fatty meals can significantly delay Viagra's absorption, potentially reducing its effectiveness or delaying onset by up to an hour. Tadalafil is less affected by food intake, making it more suitable for those who prefer not to plan meals around medication. For optimal Viagra effectiveness, consider taking it on an empty stomach or after a light meal.

Dosage and Frequency

Viagra is available in 25mg, 50mg, and 100mg strengths, with 50mg being the standard starting dose. Only one dose should be taken within any 24-hour period. Tadalafil comes in both daily (2.5mg, 5mg) and as-needed formulations (10mg, 20mg), offering more flexibility in treatment approaches.

Cost Considerations: Branded vs Generic

At EverydayMeds, patients can choose between branded Viagra and generic sildenafil during checkout. Both contain identical active ingredients and provide equivalent effectiveness, but generic sildenafil typically costs significantly less. This makes sildenafil an attractive option for men seeking cost-effective ED treatment without compromising on quality.

Side Effects and Tolerability

Common side effects of sildenafil include headache, facial flushing, and nasal congestion, which typically resolve within a few hours. Tadalafil may cause similar effects but can also lead to back pain and muscle aches in some users. The shorter duration of Viagra means any side effects are generally shorter-lived compared to tadalafil.

Choosing the Right Treatment

Your choice between Viagra and tadalafil should depend on your lifestyle, relationship patterns, and personal preferences. Viagra suits those who prefer planned intimacy and shorter medication windows, whilst tadalafil benefits those seeking spontaneity and longer effectiveness periods. EverydayMeds' clinical team can help determine which option best suits your individual circumstances.

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.
