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 ED Treatment Durations and Effectiveness

How Long Does Viagra Last?

Viagra typically remains effective for 4-6 hours after taking a dose. This doesn't mean you'll have an erection for this entire period - rather, the medication helps you achieve and maintain erections when sexually aroused during this window. Most men notice effects beginning 30-60 minutes after taking Viagra, though fatty meals can delay this onset.

Generic Sildenafil: Same Duration, Better Value

Generic sildenafil contains the identical active ingredient as Viagra and offers the same 4-6 hour duration of action. The main difference lies in cost - sildenafil typically costs significantly less than branded Viagra whilst providing equivalent effectiveness. EverydayMeds offers both options at checkout, allowing you to choose between branded Viagra or more affordable generic sildenafil based on your preferences and budget.

Extended Duration Options: Tadalafil

For those seeking longer-lasting treatment, tadalafil offers extended duration benefits of up to 36 hours. This extended window provides greater spontaneity, as you don't need to time sexual activity as precisely. Tadalafil is available both as Cialis (branded) and generic versions, with the latter offering better value whilst maintaining the same extended duration.

Choosing Based on Your Lifestyle

Your choice between different ED treatments might depend on how frequently you're sexually active and whether you prefer planned or spontaneous intimacy. Viagra and sildenafil work well for planned sexual activity within their 4-6 hour window, whilst tadalafil's extended duration suits those preferring less time-sensitive options.

Factors Affecting Duration

Several factors can influence how long ED medications remain effective. Age, overall health, other medications, alcohol consumption, and food intake all play roles. Fatty meals can delay onset but don't typically reduce overall duration. Excessive alcohol may reduce effectiveness and duration of all ED treatments.

Prescription Requirements and Safety

All effective ED treatments require prescription following consultation with UK-licensed prescribers. This ensures the medication suits your health profile and doesn't interact with other treatments. EverydayMeds provides convenient online consultations, making it easier to access appropriate treatment whilst maintaining safety standards.

Getting Started with Treatment

Most men start with 50mg doses, whether choosing Viagra or generic sildenafil. Doses can be adjusted based on effectiveness and any side effects experienced. The maximum recommended frequency is once per 24 hours, regardless of which medication you choose.

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.
