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 Empty Stomach Matters for Viagra

Viagra (sildenafil) absorbs more efficiently when taken on an empty stomach. Food, particularly fatty meals, can delay absorption and reduce the medication's effectiveness. Clinical studies show that high-fat meals can delay Viagra's onset by approximately 60 minutes compared to fasting conditions.

Optimal Timing Guidelines

For best results, take Viagra 2-3 hours after your last substantial meal. If you've eaten a light snack containing minimal fat, you may only need to wait 1-2 hours. The medication typically works within 30-60 minutes on an empty stomach, compared to 60-120 minutes when taken with food.

Foods to Avoid Before Taking Viagra

High-fat foods significantly impact Viagra's absorption. Avoid heavy meals containing fried foods, fatty meats, creamy sauces, or large portions of cheese before taking your dose. These foods can reduce peak blood levels of sildenafil by up to 29% and delay onset significantly.

Safe Options If You Need to Eat

If you must eat before taking Viagra, choose light options such as salad, lean protein, vegetables, or fruit. These foods have minimal impact on absorption. Small amounts of alcohol may be consumed safely, but excessive drinking can impair the medication's effectiveness and increase side effect risks.

Branded vs Generic Options at EverydayMeds

EverydayMeds offers both Viagra (branded) and sildenafil (generic) tablets. Both contain identical active ingredients and follow the same empty stomach guidelines. Generic sildenafil provides the same effectiveness as branded Viagra at a lower cost, giving you choice based on your preferences and budget.

What to Expect on Empty Stomach

When taken on an empty stomach, Viagra typically begins working within 30-45 minutes. You may notice effects lasting 4-6 hours, though this doesn't mean continuous erection. The medication requires sexual stimulation to be effective and works by improving blood flow when aroused.

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.
