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.

Timing Your Viagra 100mg Dose Correctly

Why Empty Stomach Matters for Viagra 100mg

Viagra 100mg (sildenafil citrate) is absorbed through the small intestine, and food can significantly impact this process. Studies show that high-fat meals can delay absorption by up to 60 minutes and reduce peak blood levels by approximately 29%. Taking Viagra on an empty stomach typically results in effects within 30-45 minutes, compared to 60-90 minutes when taken with food.

Optimal Timing Guidelines

For best results with Viagra 100mg, allow 2-3 hours after your last substantial meal before taking the tablet. If you've had a light snack containing minimal fat, waiting 1-2 hours is usually sufficient. The medication works most effectively when your stomach is relatively empty, allowing for rapid dissolution and absorption into the bloodstream.

Foods to Avoid Before Taking Viagra

High-fat foods are particularly problematic and should be avoided for several hours before your dose. These include fried foods, fatty meats, full-fat dairy products, nuts, and rich sauces. Heavy meals generally slow gastric emptying, keeping the medication in your stomach longer rather than moving to the small intestine where absorption occurs.

Acceptable Light Foods

If you need to eat something before taking Viagra 100mg, opt for light, low-fat options. Fresh fruit, plain toast, or a small portion of lean protein are generally acceptable. These foods are digested quickly and are unlikely to significantly impact the medication's absorption rate.

Branded vs Generic Options

Both branded Viagra and generic sildenafil follow the same empty stomach guidelines, as they contain identical active ingredients. EverydayMeds provides both options, allowing patients to choose based on preference and budget whilst maintaining the same clinical effectiveness and timing recommendations.

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.
