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 Problems & Professional Solutions

Sildenafil Not Working Effectively

If your sildenafil tablet isn't providing expected results, several factors may be involved. Timing is crucial - take your medication 30-60 minutes before sexual activity. Fatty meals can delay absorption by up to 2 hours, so consider taking sildenafil on an empty stomach. Remember that sexual arousal is still required as sildenafil doesn't cause automatic erections.

Dosage Adjustment Considerations

Your initial sildenafil prescription typically starts at 50mg, but this may need adjustment. If effects are insufficient, your prescriber might recommend increasing to 100mg. Conversely, if you experience significant side effects, a reduction to 25mg could be appropriate. Never adjust your dose without clinical guidance. EverydayMeds offers both generic sildenafil and branded Viagra options during checkout, allowing you to choose based on your preference and budget.

Managing Common Side Effects

Mild side effects like headaches, facial flushing, or nasal congestion are relatively common with sildenafil tablets. These typically resolve within a few hours. Staying hydrated and taking paracetamol can help manage headaches. However, if you experience chest pain, sudden vision changes, or prolonged erections lasting over 4 hours, seek immediate medical attention.

Interaction Concerns

Certain medications can affect sildenafil effectiveness or cause dangerous interactions. Alpha-blockers for blood pressure may cause excessive blood pressure drops when combined with sildenafil. Never take sildenafil with nitrates (GTN sprays or tablets) as this can cause life-threatening blood pressure reduction. Always inform prescribers about all medications you're taking.

When to Seek Professional Advice

Contact your prescriber if sildenafil tablets aren't working after several attempts, if side effects persist or worsen, or if your health circumstances change. Our UK-licensed clinicians can review your treatment, consider dose adjustments, or explore alternative options. Regular follow-ups ensure your treatment remains safe and effective for your individual circumstances.

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.
