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 Emergency Signs and When Professional Help is Essential

Immediate Medical Emergencies Requiring Urgent Care

Certain side effects of Viagra Connect constitute medical emergencies requiring immediate attention. Priapism, an erection lasting more than 4 hours, represents the most serious emergency. This painful condition can cause permanent damage to penile tissue if not treated promptly. Contact emergency services or attend A&E immediately if this occurs.

Sudden vision loss in one or both eyes, though rare, requires immediate medical assessment. This condition, called non-arteritic anterior ischemic optic neuropathy (NAION), has been reported in men taking PDE5 inhibitors. Similarly, sudden hearing loss or severe tinnitus (ringing in ears) warrants urgent medical evaluation.

Chest pain occurring during or after sexual activity should never be ignored. Stop sexual activity immediately and seek emergency medical help, as this may indicate serious cardiovascular complications.

Cardiovascular Warning Signs

Men experiencing dizziness, fainting, or severe drops in blood pressure after taking Viagra Connect should consult their doctor promptly. These symptoms may indicate that Viagra Connect isn't suitable for your cardiovascular health status or that dosage adjustment is needed through prescription alternatives.

If you develop irregular heartbeat, severe chest discomfort, or breathing difficulties, discontinue Viagra Connect and seek immediate medical attention. The MHRA guidelines emphasise that sexual activity itself places demands on the heart, and any cardiovascular symptoms require professional assessment.

When Over-the-Counter Treatment Isn't Sufficient

If Viagra Connect 50mg proves ineffective after several attempts, consult your GP or consider our prescription service. Many men require different dosages - either 25mg for those experiencing side effects, or 100mg for enhanced effectiveness. EverydayMeds provides access to these alternative strengths through our clinical assessment process.

Persistent erectile dysfunction despite using Viagra Connect correctly may indicate underlying health conditions requiring investigation. Diabetes, cardiovascular disease, hormonal imbalances, or psychological factors might need addressing alongside ED treatment.

Medication Interactions and Contraindications

Never combine Viagra Connect with nitrate medications (GTN spray, isosorbide) as this combination can cause dangerous blood pressure drops. If you require nitrate treatment, stop using Viagra Connect immediately and inform your prescriber about your ED medication history.

Men taking alpha-blockers for prostate problems should consult their doctor before using Viagra Connect, as significant blood pressure reductions can occur. Similarly, those on blood pressure medications may require monitoring or dosage adjustments.

Persistent or Troublesome Side Effects

While mild side effects like headaches, facial flushing, or nasal congestion often diminish with continued use, persistent or severe reactions warrant medical review. Your doctor can assess whether prescription alternatives like generic sildenafil at different strengths might suit you better.

Visual disturbances beyond typical blue-tinted vision, severe indigestion, or persistent dizziness should prompt consultation with your healthcare provider. These symptoms may indicate that Viagra Connect isn't optimal for your individual circumstances.

Underlying Health Condition Assessment

New-onset erectile dysfunction, particularly if sudden or severe, requires medical evaluation to rule out underlying conditions. Cardiovascular disease, diabetes, hormonal disorders, or neurological conditions can manifest as ED and require specific treatment.

Men with existing health conditions like heart disease, liver problems, or kidney disease should have regular medical reviews when using any ED medication. Your doctor can monitor how treatment affects your overall health status.

Psychological and Relationship Factors

When ED significantly impacts mental health, self-esteem, or relationships, professional support becomes essential. Your GP can refer you to appropriate counselling services or sexual health specialists who address both physical and psychological aspects of erectile dysfunction.

Depression, anxiety, or relationship difficulties often contribute to ED and may require treatment alongside physical interventions. Comprehensive care addresses all contributing factors for optimal outcomes.

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.
