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.

Common Viagra Side Effects You Should Know

How to Order Viagra Safely Online

EverydayMeds makes accessing ED treatment straightforward and secure. Begin with our comprehensive online consultation, completed by UK-licensed prescribers who assess your medical history, current medications, and cardiovascular health. This clinical evaluation ensures Viagra is suitable for you whilst identifying any factors that might increase side effect risks. Following approval, you can choose between branded Viagra or generic sildenafil at checkout - both contain the same active ingredient but at different price points.

Understanding Common Viagra Side Effects

Most men tolerate Viagra well, but understanding potential side effects helps you use the medication safely. Common side effects include headaches, facial flushing, indigestion, nasal congestion, and dizziness. These effects typically occur because sildenafil affects blood vessels throughout the body, not just in the penis. Headaches affect approximately 16% of users, whilst facial flushing occurs in around 10% of cases. These side effects are usually mild and diminish as your body adjusts to the medication.

Managing Mild Side Effects Effectively

If you experience headaches, staying well-hydrated and taking paracetamol may help - avoid aspirin as it can increase bleeding risk when combined with sildenafil. For indigestion, taking Viagra on an empty stomach or with a light meal reduces stomach irritation. Facial flushing and nasal congestion typically resolve within a few hours as the medication clears your system. Dizziness can be minimised by rising slowly from sitting or lying positions, as sildenafil can cause temporary blood pressure changes.

Serious Side Effects Requiring Immediate Attention

Whilst rare, serious side effects require immediate medical attention. Priapism - an erection lasting over four hours - affects less than 1% of users but constitutes a medical emergency requiring immediate hospital treatment. Sudden vision changes, including temporary vision loss, occur very rarely but need urgent assessment. Similarly, sudden hearing loss or severe chest pain during sexual activity requires immediate medical help. These serious effects are uncommon but understanding warning signs ensures prompt treatment if they occur.

Drug Interactions and Contraindications

Certain medications create dangerous interactions with Viagra. Never combine sildenafil with nitrates (GTN spray, isosorbide tablets) as this combination can cause life-threatening blood pressure drops. Alpha-blockers used for prostate problems may also cause problematic interactions. Our online consultation specifically checks for these dangerous combinations. Men with severe heart conditions, recent strokes, or very low blood pressure may not be suitable candidates for Viagra treatment.

Minimising Side Effects and Maximising Safety

Several strategies help minimise side effects whilst maintaining effectiveness. Start with the lowest effective dose - typically 50mg - which can be adjusted based on response and tolerability. Avoid excessive alcohol consumption, which increases side effect risks and reduces effectiveness. Fatty meals can delay absorption and potentially increase side effects. Our prescribers provide personalised guidance on optimal timing and dosing based on your individual circumstances and medical history.

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.
