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.

Why Viagra Causes Headaches and Prevention Tips

Understanding Viagra-Related Headaches

Viagra (sildenafil citrate) can cause headaches in approximately 16% of users due to its mechanism of action. As a PDE5 inhibitor, Viagra increases blood flow not only to the penis but throughout the body, including blood vessels in the head. This vasodilation effect can trigger tension headaches or mild migraines in some patients.

Immediate Relief Strategies

If you experience a headache after taking Viagra, paracetamol or ibuprofen can provide effective relief. Ensure you're well-hydrated by drinking plenty of water, as dehydration can worsen headaches. Applying a cold compress to your forehead or neck may also help reduce discomfort. Rest in a quiet, dimly lit room until symptoms subside.

Prevention Methods

Taking Viagra on an empty stomach with a full glass of water may reduce headache likelihood. Avoid alcohol consumption, which can exacerbate side effects and increase headache severity. Consider timing your dose earlier in the day rather than late evening, as this allows any side effects to diminish before sleep.

Dosage Considerations

Starting with the lowest effective dose (typically 25mg) can minimise headache occurrence whilst still providing treatment benefits. Your prescriber may recommend dose adjustment based on your tolerance. Both Viagra and generic sildenafil are available in 25mg, 50mg, and 100mg strengths, allowing flexible dosing options.

Alternative Treatment Options

EverydayMeds offers both branded Viagra and generic sildenafil containing the same active ingredient. Some patients find switching between formulations helps reduce side effects whilst maintaining effectiveness. Generic sildenafil provides a cost-effective alternative with identical therapeutic benefits. Your online consultation will determine the most suitable option for your individual circumstances.

When to Seek Medical Advice

Consult your prescriber if headaches persist beyond 4 hours, become severe, or are accompanied by vision changes or chest pain. These symptoms may indicate the need for dosage adjustment or alternative treatment approaches. Never exceed one dose per 24-hour period, regardless of side effects experienced.

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.
