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 Viagra Tablet Cost and Effectiveness

How Viagra and Sildenafil Compare to Tadalafil

Both sildenafil (the active ingredient in Viagra) and tadalafil belong to the same class of medications called PDE5 inhibitors. They work by increasing blood flow to the penis during sexual arousal. The key difference lies in their duration of action - whilst Viagra and sildenafil typically remain effective for 4-6 hours, tadalafil may work for up to 36 hours, earning it the nickname "the weekend pill".

Viagra Tablet Cost Considerations

When evaluating treatment options, cost is often a significant factor. Branded Viagra tends to be more expensive than generic sildenafil, despite containing the same active ingredient in identical doses. At EverydayMeds, patients can choose between branded Viagra or generic sildenafil at checkout, with the generic option typically offering considerable savings whilst maintaining the same clinical effectiveness.

Onset and Duration Differences

Viagra and sildenafil usually begin working within 30-60 minutes of taking the tablet, with peak effectiveness occurring around 1-2 hours after ingestion. Food, particularly fatty meals, may delay the onset. Tadalafil also typically starts working within 30-60 minutes but offers a longer window of effectiveness, which some men find more convenient for spontaneous intimacy.

Dosage Options and Flexibility

Sildenafil is available in 25mg, 50mg, and 100mg strengths, with 50mg being the typical starting dose. Tadalafil is commonly prescribed in 10mg and 20mg doses for on-demand use, or 2.5mg and 5mg for daily use. The choice between these options depends on your lifestyle, frequency of sexual activity, and how your body responds to treatment.

Side Effects and Tolerability

Both medications share similar side effect profiles, including potential headaches, flushing, nasal congestion, and indigestion. Some men tolerate one medication better than the other. Tadalafil's longer duration means side effects, if they occur, may also last longer. It's important to discuss any concerns with a healthcare provider during your consultation.

Making Your Choice

The decision between Viagra, sildenafil, or tadalafil often comes down to personal preference, lifestyle factors, and cost considerations. Some men prefer the shorter duration of sildenafil for planned intimate moments, whilst others favour tadalafil's longer window of effectiveness. Generic sildenafil offers an economical alternative to branded Viagra without compromising on quality or effectiveness.

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.
