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.

Troubleshooting Your Viagra Treatment

Viagra Not Working? Check These Common Issues

If Viagra isn't providing expected results, several factors may be affecting its effectiveness. Timing is crucial - take your tablet 30-60 minutes before sexual activity on a relatively empty stomach. Heavy or fatty meals can delay absorption by up to 2 hours. Alcohol consumption may also reduce effectiveness and increase side effects. Remember that sexual arousal is still required - Viagra enhances natural response but doesn't create automatic erections.

Managing Common Side Effects

Most men tolerate Viagra well, but some experience mild side effects including headaches, facial flushing, indigestion, or nasal congestion. These typically resolve within a few hours. Stay hydrated and avoid alcohol to minimise discomfort. If you experience chest pain, sudden vision or hearing loss, or an erection lasting over 4 hours, seek immediate medical attention. At EverydayMeds, our clinical team can adjust your dosage or suggest switching between branded Viagra and generic sildenafil if needed.

Dosage Adjustments and Alternatives

Starting doses are typically 50mg, but this can be adjusted based on effectiveness and tolerability. If 50mg proves insufficient, your prescriber may increase to 100mg or reduce to 25mg if side effects occur. Some men find generic sildenafil more suitable due to different inactive ingredients. Both contain the same active ingredient but may have slightly different absorption rates. Never exceed one dose per 24 hours regardless of effectiveness.

When to Contact Your Healthcare Provider

Certain situations require immediate professional advice. Contact your GP or our clinical team if you experience severe side effects, if effectiveness suddenly decreases, or if you start new medications. Always inform healthcare providers about your Viagra use before any medical procedures. If you develop chest pain during sexual activity, stop immediately and seek medical help. Regular medication reviews ensure continued safety and effectiveness of your treatment.

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.
