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.

Understanding Viagra and Sildenafil Treatment Options

What is Viagra and How Does It Work?

Viagra is the brand name for sildenafil citrate, originally developed by Pfizer. As a PDE5 inhibitor, it works by blocking the phosphodiesterase type 5 enzyme, which increases blood flow to the penis when sexually aroused. It's important to understand that Viagra does not cause automatic erections - sexual stimulation is still required for the medication to be effective. The medication typically works within 30-60 minutes of taking it, with effects potentially lasting 4-6 hours, though this doesn't mean an erection will last this entire duration.

Branded vs Generic: Viagra or Sildenafil?

At EverydayMeds, patients can choose between branded Viagra and generic sildenafil at checkout. Both contain the same active ingredient (sildenafil citrate) and work identically. The main difference is cost - generic sildenafil offers the same therapeutic benefits at a more affordable price point. This choice allows patients to select the option that best fits their budget whilst receiving the same clinical effectiveness.

Available Dosages and Usage Guidelines

Sildenafil is available in three strengths: 25mg, 50mg, and 100mg tablets. The typical starting dose is 50mg, taken approximately 30-60 minutes before sexual activity. Depending on effectiveness and tolerability, the dose may be adjusted to 25mg (if side effects occur) or increased to 100mg (if 50mg is insufficient). It's crucial to take only one dose per 24-hour period. Food, particularly fatty meals, can delay the medication's onset of action.

Who Can Take Viagra?

Viagra is suitable for adult men (18+) experiencing erectile dysfunction. However, not everyone is eligible for this treatment. A clinical assessment is required to evaluate cardiovascular health, current medications, and medical history. Men taking nitrate medications (such as GTN spray), those with severe heart conditions, recent heart attack or stroke (within 6 months), severe liver problems, or very low blood pressure should not take sildenafil. The medication is not suitable for women or men under 18 years of age.

Potential Side Effects and Safety Considerations

Common side effects may include headaches, facial flushing, indigestion, and nasal congestion. These are usually mild and temporary. More serious but rare side effects include sudden vision or hearing loss, chest pain, or erections lasting more than 4 hours (priapism). If any serious side effects occur, seek immediate medical attention. Always inform your prescriber about all medications you're taking, including over-the-counter remedies and herbal supplements.

Legal Requirements for Online Purchase

In the UK, both Viagra and sildenafil are prescription-only medicines (POM) requiring a valid prescription from a UK-licensed prescriber. When buying online, you must complete a comprehensive clinical assessment reviewed by qualified healthcare professionals. EverydayMeds operates under strict regulatory guidelines, ensuring all consultations meet MHRA and GPhC standards. This process protects patient safety whilst providing convenient access to legitimate treatment.

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.
