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.

Medical Warning Signs Requiring Immediate Attention

Emergency Situations Requiring Immediate Medical Help

Certain symptoms whilst taking sildenafil 50mg require urgent medical attention. If you experience chest pain, dizziness, or nausea during sexual activity, stop immediately and seek emergency care. An erection lasting longer than 4 hours (priapism) is a medical emergency that can cause permanent damage if untreated. Sudden loss of vision or hearing, though rare, requires immediate medical evaluation.

Cardiovascular Concerns and Risk Factors

Men with existing heart conditions should consult their GP before starting sildenafil treatment. This includes those with recent heart attacks, strokes, severe heart failure, or unstable angina. If you're taking nitrate medications for chest pain, sildenafil is contraindicated due to dangerous blood pressure interactions. Regular blood pressure monitoring may be recommended for some patients.

When Treatment Isn't Working Effectively

If sildenafil 50mg isn't providing adequate results after several attempts, speak with your prescriber rather than increasing the dose independently. They may adjust your dosage to 25mg or 100mg, or explore underlying causes. Factors like diabetes, stress, relationship issues, or other medications can affect treatment effectiveness.

Side Effects Requiring Medical Review

Common side effects like headaches, facial flushing, or mild indigestion typically improve with continued use. However, severe or persistent side effects warrant medical review. These include severe headaches, prolonged digestive upset, or skin reactions. Some men may benefit from switching between generic sildenafil and branded Viagra, as inactive ingredients can vary.

Regular Health Monitoring

Annual health reviews are recommended for men on long-term sildenafil treatment, particularly those over 65 or with underlying health conditions. This allows monitoring of cardiovascular health, medication interactions, and treatment effectiveness. EverydayMeds' consultation process includes regular assessment opportunities with UK-licensed prescribers.

Drug Interactions and New Medications

Always inform healthcare providers that you're taking sildenafil when prescribed new medications. Particular caution is needed with blood pressure medications, alpha-blockers, and certain antifungal or antibiotic treatments. Your prescriber can advise on timing or dosage adjustments to maintain safety whilst continuing effective ED 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.
