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.

Understanding and Managing Common Viagra Side Effects

Most Common Side Effects and Management Strategies

Headaches affect more than 1 in 10 men taking Viagra and represent the most frequently reported side effect. These headaches typically occur within 30-60 minutes of taking the medication and usually resolve within a few hours. To manage headaches effectively, consider taking a standard dose of paracetamol or ibuprofen, ensuring adequate hydration before and after taking Viagra, and avoiding alcohol which can worsen both headaches and other side effects.

Facial flushing is another common side effect, causing redness and warmth in the face, neck and chest. This occurs due to increased blood flow and usually subsides within 2-4 hours. Management strategies include staying in cooler environments, wearing breathable clothing, avoiding spicy foods and hot drinks around the time of taking Viagra, and using a cool, damp cloth on the face if needed.

Digestive and Nasal Side Effects

Indigestion and nasal congestion affect approximately 1 in 10 men taking Viagra. Indigestion symptoms include stomach discomfort, acid reflux and general digestive upset. To minimise these effects, take Viagra on an empty stomach or after a light meal, avoid fatty or spicy foods for several hours before taking the medication, and consider using over-the-counter antacids if symptoms occur.

Nasal congestion can cause a stuffy or blocked nose feeling. Simple management includes using saline nasal sprays, staying well-hydrated, and avoiding environments with strong scents or allergens. If congestion is particularly troublesome, a short-term decongestant may help, though you should consult your prescriber before combining medications.

Visual and Dizziness Management

Some men experience mild visual disturbances, including a slight blue tinge to vision or increased light sensitivity. These effects are usually mild and temporary. Management involves avoiding bright lights immediately after taking Viagra, wearing sunglasses if outdoors, and avoiding activities requiring precise vision until effects subside. If visual changes are severe or persistent, discontinue use and seek immediate medical advice.

Dizziness can occur due to mild blood pressure changes. To manage dizziness, avoid sudden position changes, sit or lie down if feeling dizzy, ensure adequate hydration throughout the day, and avoid alcohol which can worsen dizziness. Getting up slowly from sitting or lying positions can prevent sudden dizzy spells.

Dosage Considerations for Side Effect Management

Side effects are often dose-related, meaning they may be more noticeable at higher doses. If you're experiencing troublesome side effects on 50mg or 100mg, discussing a dose reduction to 25mg with your prescriber may help maintain effectiveness whilst reducing side effects. Conversely, some men find that splitting the dose timing or adjusting when they take Viagra relative to meals can impact side effect severity.

EverydayMeds offers both branded Viagra and generic sildenafil in all available strengths, allowing flexibility in finding the most tolerable dose. Our clinical team can guide dosage adjustments based on your individual response and side effect profile during follow-up consultations.

When to Seek Immediate Medical Help

Whilst most side effects are manageable, certain symptoms require immediate medical attention. Priapism, an erection lasting more than 4 hours, is a medical emergency requiring immediate hospital treatment. Sudden vision loss in one or both eyes, sudden hearing loss or severe chest pain during sexual activity also require emergency care.

Severe allergic reactions, though rare, can include difficulty breathing, severe swelling of face or throat, or widespread rash. If you experience any of these symptoms, stop taking Viagra immediately and seek emergency medical help.

Long-term Side Effect Management

Many men find that side effects become less noticeable over time as their body adjusts to the medication. Keeping a simple diary of side effects during your first few uses can help identify patterns and effective management strategies. This information is valuable during clinical reviews and can help optimise your treatment plan.

Regular follow-up consultations allow monitoring of side effects and treatment effectiveness. EverydayMeds provides ongoing clinical support, ensuring any concerns about side effects are addressed promptly and professionally throughout your treatment journey.

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.
