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.

Sildenafil 50mg Dosage and Administration Guidelines

How Sildenafil 50mg Works

Sildenafil 50mg works by inhibiting the PDE5 enzyme, which increases blood flow to the penis when sexually aroused. This generic medication contains the same active ingredient as branded Viagra, offering equivalent effectiveness at a lower cost. The medication requires sexual stimulation to work and does not cause automatic erections.

Proper Dosage Instructions

The recommended starting dose is sildenafil 50mg, taken approximately 30-60 minutes before anticipated sexual activity. Based on individual response and tolerability, your prescriber may adjust the dose to 25mg or increase to 100mg. Never exceed one tablet within a 24-hour period, regardless of the strength prescribed.

Timing and Food Considerations

For optimal results, take sildenafil 50mg on an empty stomach or after a light meal. Heavy or fatty foods may delay the medication's onset of action. The effects typically begin within 30-60 minutes and may last up to 4-6 hours, though this does not mean an erection will persist throughout this period.

Choosing Between Generic and Branded Options

EverydayMeds provides flexibility by offering both sildenafil (generic) and Viagra (branded) at checkout. Both contain identical active ingredients and demonstrate equivalent clinical effectiveness. The choice often comes down to personal preference and budget considerations, as generic sildenafil typically costs less than branded Viagra.

Safety Considerations and Contraindications

Sildenafil 50mg is not suitable for everyone. Men taking nitrate medications (such as GTN spray), those with severe heart conditions, or recent stroke/heart attack history should not use this medication. Always complete the online consultation honestly to ensure safe prescribing. Our UK-licensed prescribers review all medical information before approving treatment.

Our clinical team will review your medical history, current medications, and health status to determine if sildenafil 50mg is appropriate.

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.
