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.

Your Viagra and Sildenafil Options in the UK

Over-the-Counter vs Prescription Options

Viagra Connect, containing 50mg sildenafil, became available over-the-counter in UK pharmacies in 2018. This provides a convenient option for men seeking ED treatment without a GP visit. However, prescription treatments through services like EverydayMeds may offer several advantages, including personalised dosage adjustment and choice between branded Viagra or more affordable generic sildenafil.

Dosage Flexibility with Prescription Treatment

Prescription sildenafil and Viagra are available in 25mg, 50mg, and 100mg strengths. Your prescriber can recommend the most appropriate starting dose based on your medical history and adjust this if needed. The typical starting dose is 50mg, taken approximately one hour before sexual activity. Some patients may benefit from the lower 25mg dose to minimise potential side effects, whilst others may require the higher 100mg dose for optimal effectiveness.

Choosing Between Branded and Generic

Both Viagra and generic sildenafil contain the same active ingredient and work identically. The choice often comes down to personal preference and cost considerations. EverydayMeds offers both options at checkout, allowing you to select based on your individual needs. Generic sildenafil typically costs significantly less whilst providing equivalent clinical effectiveness.

Safety Considerations and Medical Assessment

Whether choosing over-the-counter or prescription treatment, a proper medical assessment is essential. Sildenafil can interact dangerously with certain medications, particularly nitrates used for chest pain. It may also not be suitable for men with certain cardiovascular conditions. EverydayMeds' online consultation process ensures that treatment is clinically appropriate and safe for each individual patient.

How to Access Treatment Through EverydayMeds

Our streamlined process begins with a confidential online consultation with a UK-registered prescriber. If treatment is deemed suitable, you can choose between branded Viagra or generic sildenafil, with various quantity options available. All medications are dispensed by our UK-registered pharmacy and delivered discretely to your chosen address, typically within 24-48 hours of approval.

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.

Can I buy Viagra over the counter in the UK?
Viagra Connect 50mg is available over-the-counter from UK pharmacies following a consultation with the pharmacist. Prescription-strength Viagra in 25mg, 50mg, and 100mg requires a consultation with a prescriber through services like EverydayMeds.
What's the difference between Viagra and sildenafil?
Viagra is the branded version manufactured by Pfizer, whilst sildenafil is the generic equivalent. Both contain the same active ingredient and work identically, but generic sildenafil typically costs significantly less.
How long does Viagra take to work?
Viagra and sildenafil typically begin working within 30-60 minutes of taking the tablet. The effects can last up to 4-6 hours, though this doesn't mean an erection will last this long - sexual stimulation is still required.
Can I take Viagra with other medications?
Viagra should never be taken with nitrate medications (such as GTN spray) as this can cause a dangerous drop in blood pressure. Always disclose all medications during your consultation to ensure safe prescribing.
Which dosage of Viagra should I take?
The typical starting dose is 50mg, taken approximately one hour before sexual activity. Your prescriber may recommend 25mg if you're prone to side effects, or 100mg if 50mg proves insufficient. Only one dose should be taken in any 24-hour period.
