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.

Generic vs Branded Sildenafil: Understanding Your Options

What Are Sildenafil Tablets?

Sildenafil tablets contain the same active pharmaceutical ingredient found in Viagra - sildenafil citrate. As a PDE5 inhibitor, sildenafil works by increasing blood flow to the penis during sexual arousal, helping men achieve and maintain erections suitable for sexual activity. The medication requires sexual stimulation to be effective and does not cause automatic erections.

Generic Sildenafil vs Branded Viagra

The primary difference between generic sildenafil and Viagra lies in cost rather than effectiveness. Both medications contain identical active ingredients in the same concentrations and undergo rigorous testing to meet UK medicine safety standards. Generic sildenafil typically costs 60-80% less than branded Viagra, making it an economical choice for many patients. EverydayMeds stocks both options, allowing patients to select their preference during the checkout process.

How Sildenafil Tablets Work

Sildenafil blocks the PDE5 enzyme, which normally breaks down chemicals responsible for maintaining erections. By inhibiting this enzyme, sildenafil allows blood vessels in the penis to remain relaxed and dilated longer, improving blood flow when sexually stimulated. The medication typically begins working within 30-60 minutes of taking and may remain effective for 4-6 hours, though this varies between individuals.

Dosages and Usage Guidelines

Sildenafil tablets are available in 25mg, 50mg, and 100mg strengths. Most men start with 50mg, taken approximately one hour before planned sexual activity. Depending on effectiveness and tolerability, the dose may be adjusted to 25mg or increased to 100mg. Only one tablet should be taken within any 24-hour period. Taking sildenafil with heavy or fatty meals may delay its onset of action.

Who Can Use Sildenafil Tablets

Sildenafil is suitable for adult men experiencing erectile dysfunction. However, it requires a prescription following consultation with a qualified healthcare provider. The medication is not appropriate for men taking nitrate medications, those with severe heart conditions, or individuals with certain medical histories. EverydayMeds' UK-licensed prescribers conduct thorough assessments to ensure sildenafil is safe and suitable for each patient.

Side Effects and Safety Considerations

Common side effects of sildenafil may include headaches, facial flushing, indigestion, and nasal congestion. These effects are generally mild and temporary. More serious side effects, though rare, can include sudden vision or hearing loss, prolonged erections lasting over four hours, or chest pain. Patients should seek immediate medical attention for serious side effects. Sildenafil should never be combined with nitrate medications due to dangerous blood pressure interactions.

Getting Sildenafil Through EverydayMeds

EverydayMeds provides convenient access to both generic sildenafil and branded Viagra through our regulated online service. After completing a confidential medical questionnaire, UK-licensed prescribers review each case to ensure appropriate treatment selection. Approved orders are dispensed by our registered pharmacy and delivered discreetly to patients' chosen addresses, typically within 1-2 working days across the UK.

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.
