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 Side Effects and Practical Management Tips

Headaches and How to Manage Them

Headaches affect approximately 15% of men taking sildenafil 50mg. These typically occur due to blood vessel dilation. To manage headaches, ensure adequate hydration by drinking plenty of water throughout the day. Over-the-counter paracetamol may help, but avoid exceeding recommended doses. If headaches persist or become severe, consult your prescriber about adjusting your dose or switching between generic sildenafil and branded Viagra options.

Facial Flushing and Warmth

Facial flushing occurs in around 10% of users due to increased blood flow. This side effect usually subsides within 2-4 hours. Stay in cool environments when possible and avoid hot beverages or spicy foods immediately after taking sildenafil. Loose, breathable clothing can also help you feel more comfortable whilst the medication takes effect.

Digestive Issues and Nausea

Some men experience mild stomach upset or nausea with sildenafil 50mg. Taking the tablet with a small amount of food can help, though avoid heavy, fatty meals which may delay effectiveness. Ginger tea or plain biscuits may settle mild nausea. If digestive issues persist, discuss timing adjustments with your healthcare provider.

Nasal Congestion and Stuffiness

Nasal congestion affects roughly 4% of sildenafil users. This occurs due to blood vessel dilation in nasal passages. Saline nasal sprays can provide relief without interfering with sildenafil's effectiveness. Avoid decongestants containing phenylephrine unless approved by your prescriber, as these may interact with ED medications.

When to Seek Medical Advice

Contact your prescriber immediately if you experience persistent erections lasting over 4 hours, sudden vision changes, or severe dizziness. Most side effects are mild and temporary, but your healthcare provider can adjust dosages or recommend switching between sildenafil generic and Viagra branded options if needed. EverydayMeds' UK-licensed prescribers are available for follow-up consultations to optimise your treatment plan.

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.
