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.

Common Sildenafil Issues & Quick Solutions

Not Working Effectively?

If sildenafil citrate isn't providing expected results, several factors may be involved. Timing is crucial - take your dose 30-60 minutes before sexual activity on a relatively empty stomach. Heavy or fatty meals can significantly delay absorption and reduce effectiveness. Your prescriber may recommend adjusting from the standard 50mg dose to 25mg or 100mg depending on your response and tolerability.

Managing Side Effects

Common side effects include headache, facial flushing, and nasal congestion. These typically resolve within a few hours. Stay hydrated and avoid alcohol, which can worsen side effects and reduce effectiveness. If you experience severe headaches, visual disturbances, or prolonged erections lasting over 4 hours, seek immediate medical attention. Our pharmacy team can advise on managing mild side effects.

Medication Interactions

Never combine sildenafil with nitrate medications (GTN spray, isosorbide) as this can cause dangerous blood pressure drops. Alpha-blockers for prostate problems may also interact - your prescriber will adjust timing if both medications are necessary. Always inform healthcare providers about all medications you're taking, including over-the-counter supplements.

Choosing Between Generic and Branded

EverydayMeds offers both sildenafil (generic) and Viagra (branded) options at checkout. Both contain identical active ingredient sildenafil citrate and work equally effectively. Generic sildenafil provides the same clinical benefits at a lower cost. Some patients prefer the familiarity of branded Viagra - the choice is entirely yours based on personal preference and budget.

When to Contact Your Prescriber

Reach out if sildenafil stops working effectively after previously successful use, if you develop new medical conditions, or if you're prescribed new medications. Changes in cardiovascular health, diabetes control, or stress levels can affect treatment response. Our UK-licensed prescribers can review your case and adjust treatment accordingly through our secure patient portal.

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.
