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 Medication Options

How Viagra Pills and Tadalafil Work

Both Viagra pills (sildenafil) 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 pharmacological properties, particularly duration of action and onset time.

Comparing Effectiveness and Duration

Viagra pills typically take effect within 30-60 minutes and remain active for 4-6 hours. This makes them suitable for planned sexual activity. Tadalafil, however, can remain effective for up to 36 hours, earning it the nickname "the weekend pill" due to its extended window of effectiveness. Both medications demonstrate similar efficacy rates in clinical studies, with success rates typically ranging from 70-85% in men with erectile dysfunction.

Dosage and Administration Differences

Viagra pills are available in 25mg, 50mg, and 100mg strengths, with 50mg being the standard starting dose. The medication should be taken on an as-needed basis, with a maximum of one dose per 24-hour period. Tadalafil offers more flexibility with both on-demand dosing (10mg or 20mg) and daily low-dose options (2.5mg or 5mg). The daily option allows for more spontaneous sexual activity without timing considerations.

Cost Considerations: Branded vs Generic Options

At EverydayMeds, patients can choose between branded Viagra pills and generic Sildenafil at checkout. Generic Sildenafil contains the same active ingredient as Viagra but costs significantly less, making it an attractive option for long-term treatment. Both options require the same clinical assessment and provide equivalent therapeutic benefits. The choice between branded and generic often comes down to personal preference and budget considerations.

Side Effects and Tolerability Profile

Both Viagra pills and Tadalafil share similar side effect profiles, including headaches, facial flushing, nasal congestion, and indigestion. However, some patients may tolerate one medication better than the other. Tadalafil is sometimes associated with back pain and muscle aches, which are less common with sildenafil. The longer duration of Tadalafil means side effects may persist longer, whilst Viagra's shorter action window may be preferable for those experiencing adverse effects.

Making the Right Choice for Your Lifestyle

Your lifestyle and sexual activity patterns can influence which medication might be more suitable. Viagra pills work well for men who prefer planned sexual activity and want a medication that clears from their system relatively quickly. Tadalafil may be better for those who value spontaneity and don't want to time their medication around sexual activity. Our UK-licensed prescribers can help assess which option aligns best with your individual needs and medical history during your online consultation.

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.
