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.

Recognising Viagra-Related Medical Emergencies

Immediate Emergency Situations

Priapism, an erection lasting more than 4 hours, represents the most serious Viagra-related emergency. This condition can cause permanent damage to penile tissue if untreated. Seek immediate A&E attention if your erection persists beyond this timeframe, regardless of pain levels. Emergency treatment typically involves draining blood from the penis to prevent tissue damage.

Cardiovascular Warning Signs

Chest pain, severe dizziness, or fainting during sexual activity may indicate dangerous blood pressure changes. Viagra can interact with heart conditions, particularly when combined with nitrate medications. Stop sexual activity immediately and seek emergency care if experiencing chest discomfort, shortness of breath, or irregular heartbeat patterns.

Sensory Loss Emergencies

Sudden vision loss (NAION) or hearing impairment, though rare, requires immediate medical attention. These symptoms may indicate serious vascular events affecting optic or auditory nerves. Discontinue Viagra immediately and contact emergency services or attend A&E promptly if experiencing sudden sensory changes.

Severe Allergic Reactions

Anaphylaxis symptoms include difficulty breathing, severe swelling of face or throat, and widespread rash. While uncommon, allergic reactions to sildenafil can be life-threatening. Call 999 immediately if experiencing breathing difficulties, severe swelling, or widespread skin reactions after taking Viagra or sildenafil.

When to Contact Your GP

Less urgent but concerning symptoms include persistent headaches, prolonged nausea, or unusual visual disturbances. These warrant same-day GP consultation rather than emergency care. EverydayMeds patients can access clinical support through our licensed prescribers for non-emergency concerns about their treatment.

Prevention and Safe Use

Most emergencies are preventable through proper medical screening and adherence to prescribed dosages. EverydayMeds offers both branded Viagra and generic sildenafil options following comprehensive clinical assessment. Our licensed prescribers evaluate your medical history, current medications, and cardiovascular health to ensure safe treatment. Never exceed recommended dosages or combine with nitrate medications, recreational drugs, or excessive alcohol.

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.
