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 Monitor Your Viagra Treatment Progress

Initial Assessment Period

When you first buy Viagra online through EverydayMeds, your prescriber will typically start you on a 50mg dose. NHS guidelines recommend allowing 6-8 treatment attempts before evaluating effectiveness. During this period, keep a simple record of when you take your medication, the timing of sexual activity, and the overall effectiveness. Both branded Viagra and generic sildenafil require this same monitoring approach, as they contain identical active ingredients.

What to Track During Treatment

Effective monitoring involves recording several key factors. Note the time between taking your medication and sexual activity - Viagra typically works within 30-60 minutes. Track whether you achieved and maintained an erection sufficient for sexual intercourse. Document any side effects, including headaches, flushing, or nasal congestion, and their severity. This information helps your prescriber determine whether your current dose is optimal or requires adjustment.

When to Consider Dose Changes

If your initial 50mg dose proves insufficient after 6-8 attempts, your prescriber may increase it to 100mg. Conversely, if you experience bothersome side effects, a reduction to 25mg might be appropriate. NHS guidance emphasises that dose adjustments should only be made under medical supervision. EverydayMeds offers flexible dosing options for both Viagra and sildenafil, allowing your treatment to be tailored to your response.

Regular Treatment Reviews

Schedule follow-up consultations every 3-6 months to discuss your treatment progress. These reviews allow your healthcare provider to assess ongoing effectiveness, review any side effects, and consider whether your current treatment remains the best option. Your prescriber may also evaluate your cardiovascular health and review any new medications that might interact with your ED treatment.

Red Flags Requiring Immediate Medical Attention

Certain symptoms require urgent medical attention. If you experience an erection lasting more than 4 hours, seek immediate emergency care. Sudden vision or hearing loss, severe chest pain, or allergic reactions also warrant immediate medical attention. These rare but serious side effects can occur with both branded and generic versions of sildenafil.

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.
