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 Professional Consultation

Emergency Situations Requiring Immediate Medical Attention

Certain symptoms whilst taking Viagra require emergency medical care. Priapism, a painful erection lasting more than 4 hours, constitutes a medical emergency that can cause permanent damage if untreated. Contact emergency services immediately if this occurs. Similarly, sudden vision loss in one or both eyes, or sudden hearing loss with ringing in the ears, requires urgent medical evaluation as these may indicate serious complications.

Chest pain during or after sexual activity is another critical warning sign. Stop all activity immediately and seek emergency medical help, as this could indicate cardiovascular problems. Severe allergic reactions including difficulty breathing, facial swelling, or widespread rash also require immediate emergency treatment.

When to Contact Your Doctor Before Starting Viagra

Before beginning Viagra treatment, consult your doctor if you have cardiovascular conditions, take blood pressure medications, or use nitrate medications for heart conditions. Men with diabetes, liver or kidney problems, or those who've experienced heart attacks or strokes should receive medical clearance before using Viagra. Your doctor needs to assess whether you're physically fit for sexual activity and whether Viagra is appropriate for your health status.

If you're taking any regular medications, discuss potential interactions with your prescriber. This includes alpha-blockers for prostate problems, antifungal medications, HIV treatments, or certain antibiotics. EverydayMeds offers both branded Viagra and generic Sildenafil options, and your prescriber can help determine which option suits your needs during your clinical assessment.

Ongoing Treatment Concerns

Contact your doctor if Viagra becomes less effective over time or stops working entirely, as this may indicate underlying health changes requiring investigation. Similarly, if you develop new side effects or existing ones become more severe, medical review is necessary. Persistent headaches, dizziness that doesn't improve, or visual disturbances should be reported to your prescriber.

Changes in your overall health status also warrant medical consultation. New medications, recent illnesses, or changes in chronic conditions like diabetes or heart disease may affect Viagra's suitability or require dosage adjustments.

Psychological and Relationship Factors

If erectile dysfunction persists despite effective Viagra treatment, underlying psychological factors may require attention. Performance anxiety, depression, or relationship difficulties can impact treatment success. Your doctor can provide referrals to appropriate specialists or counselling services. Don't hesitate to discuss these concerns, as addressing psychological factors often improves overall treatment outcomes.

Regular Health Monitoring

Men using Viagra long-term should maintain regular contact with their healthcare provider for ongoing monitoring. Annual reviews help ensure continued treatment appropriateness and identify any developing health concerns. This is particularly important for men over 65 or those with multiple health conditions. Your prescriber may recommend periodic cardiovascular assessments to ensure you remain suitable for sexual activity and Viagra 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.
