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 Viagra UK Problems & Quick Solutions

NHS Prescription Delays and Access Issues

Many patients experience lengthy waits for NHS ED consultations, with appointment delays often extending beyond 6 weeks. GP practices may have limited availability for non-urgent sexual health consultations. EverydayMeds provides an alternative pathway through our UK-licensed prescriber service, typically processing consultations within 24 hours. Both branded Viagra and generic sildenafil are available, allowing patients to choose based on preference and budget.

Treatment Not Working Effectively

If Viagra isn't providing expected results, several factors may be involved. Fatty meals can delay onset by 30-60 minutes, whilst alcohol may reduce effectiveness. The standard 50mg starting dose may require adjustment - either reduced to 25mg if side effects occur, or increased to 100mg if response is insufficient. Timing is crucial; take medication 30-60 minutes before sexual activity. Remember that sexual stimulation is still required as Viagra doesn't cause automatic erections.

Cost Concerns and Generic Alternatives

Branded Viagra can be expensive, particularly for regular use. Generic sildenafil contains the identical active ingredient (sildenafil citrate) at typically 60-80% lower cost. Clinical studies demonstrate equivalent effectiveness between branded and generic versions. EverydayMeds offers both options at checkout, allowing patients to make informed choices. All medications are sourced from UK-licensed suppliers and undergo the same quality controls.

Side Effects and Tolerability Issues

Common side effects include headaches, facial flushing, and nasal congestion. These typically diminish with continued use or dose reduction. If side effects persist, switching to the 25mg dose often helps whilst maintaining effectiveness. Serious side effects are rare but require immediate medical attention: prolonged erections lasting over 4 hours, sudden vision changes, or chest pain during sexual activity. Always inform prescribers about existing medications, particularly nitrates or blood pressure treatments.

Avoiding Dangerous Drug Interactions

Viagra must never be combined with nitrate medications (GTN spray, isosorbide tablets) as this can cause dangerous blood pressure drops. Inform prescribers about all medications including over-the-counter treatments and herbal supplements. Alpha-blockers for prostate conditions may require dose adjustments. EverydayMeds' clinical assessment process specifically screens for these interactions to ensure safe prescribing.

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.
