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 Preventing Viagra Headaches

Why Does Viagra Cause Headaches?

Viagra and sildenafil work by relaxing blood vessels to improve blood flow to the penis. This same mechanism can affect blood vessels throughout your body, including those in your head, potentially leading to headaches. The vasodilation effect typically occurs within 30-60 minutes of taking the medication and may persist for several hours.

Immediate Headache Relief Strategies

If you develop a headache after taking Viagra, paracetamol (500mg-1g) or ibuprofen (200-400mg) are generally safe and effective options. Ensure you're well-hydrated by drinking water steadily throughout the day. Apply a cold compress to your forehead or temples for 15-20 minutes. Rest in a quiet, dimly lit environment when possible.

The Alcohol Connection

Combining Viagra with alcohol can significantly increase your risk of headaches. Alcohol causes dehydration and additional blood vessel dilation, compounding the medication's effects. Limit alcohol to one standard drink maximum, or preferably avoid it entirely when taking your medication. If you choose to drink, ensure you consume extra water throughout the evening.

Dosage Considerations

Headaches are often dose-related. If you're taking 100mg and experiencing persistent headaches, speak with your prescriber about reducing to 50mg. Many men find lower doses equally effective with fewer side effects. EverydayMeds offers both branded Viagra and generic sildenafil in 25mg, 50mg, and 100mg strengths, allowing you to find the optimal dose for your needs.

Prevention Tips

Take your medication with a full glass of water and avoid heavy, fatty meals beforehand. Ensure you're well-rested and not already dehydrated. Some men find switching between branded Viagra and generic sildenafil helpful, as individual responses can vary slightly between formulations.

When to Seek Medical Advice

Contact your prescriber if headaches are severe, persistent, or accompanied by vision changes, chest pain, or dizziness. These could indicate more serious side effects requiring immediate medical attention. Never exceed one dose per 24-hour period, even if headaches seem to reduce the medication's effectiveness.

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.
