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 Situations Requiring Doctor Consultation

Before Starting Sildenafil Citrate Treatment

Consult your doctor before beginning sildenafil citrate if you have cardiovascular conditions, take regular medications, or have experienced recent health changes. Men with heart disease, high blood pressure, diabetes, or those taking nitrate medications require careful assessment. Your prescriber will evaluate whether sildenafil citrate is suitable and determine the appropriate starting dose, typically 50mg.

When Side Effects Occur

Seek immediate medical attention if you experience chest pain, severe dizziness, or difficulty breathing after taking sildenafil. Common side effects like headaches, facial flushing, or mild stomach upset usually resolve naturally. However, persistent or worsening symptoms warrant medical review. Vision changes, including sudden loss of sight or blue-tinted vision, require urgent assessment.

Emergency Situations

Priapism - an erection lasting longer than 4 hours - constitutes a medical emergency requiring immediate hospital treatment. This rare but serious condition can cause permanent damage if untreated. Additionally, sudden hearing loss or severe allergic reactions including swelling, breathing difficulties, or widespread rash need emergency care.

Treatment Not Working Effectively

If sildenafil citrate isn't providing expected results after several attempts, discuss dosage adjustment with your prescriber. Factors affecting effectiveness include timing of doses, food consumption, alcohol intake, and underlying health conditions. Your doctor may recommend increasing to 100mg or reducing to 25mg based on your response and tolerability.

Regular Health Monitoring

Men with ongoing health conditions should maintain regular check-ups whilst using sildenafil citrate. Blood pressure monitoring is particularly important for those with cardiovascular conditions. Diabetic patients may need adjusted monitoring as improved erectile function can indicate better overall health management. EverydayMeds offers both Viagra and generic sildenafil following comprehensive clinical assessment.

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.
