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.

How to Switch to Sildenafil Treatment Online

Online Consultation Process for Switching Treatments

Changing to sildenafil or Viagra through EverydayMeds begins with our comprehensive online consultation. Our UK-licensed prescribers will review your medical history, current medications, and reasons for switching treatments. The assessment typically takes 5-10 minutes and covers your cardiovascular health, previous ED medication experiences, and any side effects you may have encountered with other treatments.

Choosing Between Viagra and Generic Sildenafil

Both options contain the same active ingredient - sildenafil citrate - and work identically to improve blood flow when sexually aroused. Viagra is the original branded medication manufactured by Pfizer, whilst generic sildenafil offers the same effectiveness at a lower cost. At checkout, you can select your preferred option based on your budget and personal preference. Both medications are available in 25mg, 50mg, and 100mg strengths.

Why Patients Switch to Sildenafil

Many men switch to sildenafil from other ED treatments due to its proven effectiveness and favourable side effect profile. Sildenafil typically works within 30-60 minutes and remains effective for 4-6 hours, though this doesn't mean erections last this duration. The medication only works when you're sexually aroused and doesn't cause automatic erections. Common reasons for switching include seeking better value with generic sildenafil, experiencing fewer side effects, or finding sildenafil more convenient to use than alternative treatments.

Starting Your New Treatment Safely

When switching to sildenafil or Viagra, our prescribers will determine the most appropriate starting dose, typically 50mg taken 30-60 minutes before sexual activity. The dose can be adjusted to 25mg if you experience side effects, or increased to 100mg if 50mg proves insufficient. You should take a maximum of one dose per 24-hour period. Fatty meals may delay the medication's onset, so consider timing your dose accordingly.

Safety Considerations When Changing Medications

Before prescribing sildenafil or Viagra, our clinicians will check for contraindications, particularly if you take nitrate medications for chest pain, have severe heart conditions, or take certain blood pressure medications. It's crucial to inform our prescribers about all current medications and medical conditions. Common mild side effects include headaches, facial flushing, and nasal congestion, which typically improve as your body adjusts to the treatment.

Convenient Repeat Prescriptions

Once established on sildenafil or Viagra, EverydayMeds offers a streamlined repeat prescription service. You can reorder through your secure patient account, with options for regular deliveries to ensure you don't run out of treatment. Our customer support team is available to answer questions about your treatment or help adjust your prescription if needed.

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.
