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 Treatment Assessment Period

When starting Viagra or sildenafil treatment, NHS guidelines recommend allowing 4-6 attempts at sexual activity before evaluating effectiveness. This period allows your body to adjust to the medication and provides sufficient data to assess your response. Keep a simple record of when you take the medication, timing relative to sexual activity, and the outcome. EverydayMeds offers both branded Viagra and generic sildenafil, allowing you to choose the most suitable option during this assessment phase.

Tracking Treatment Response

Effective monitoring involves noting several key factors. Record the time between taking your dose and sexual activity - Viagra typically works within 30-60 minutes and remains effective for 4-6 hours. Note any factors that might affect absorption, such as heavy meals or alcohol consumption. Document the quality of erections achieved and maintained during sexual activity. This information helps determine whether dose adjustments are needed.

Side Effect Monitoring

Common side effects include headaches, facial flushing, nasal congestion, and indigestion. These typically occur within hours of taking the medication and resolve naturally. More serious side effects requiring immediate medical attention include sudden vision or hearing loss, chest pain, or erections lasting over 4 hours. Keep a record of any side effects experienced, including their severity and duration.

When to Seek Dose Adjustment

If initial results are unsatisfactory after 4-6 attempts, your prescriber may adjust your dose. The standard starting dose is 50mg, which can be reduced to 25mg if side effects occur, or increased to 100mg for improved effectiveness. Never adjust your dose without consulting a healthcare provider. EverydayMeds' clinical team can review your progress and recommend appropriate adjustments during follow-up consultations.

Long-term Monitoring Requirements

Regular health reviews every 6-12 months ensure continued treatment safety and effectiveness. These assessments evaluate your cardiovascular health, review any new medications that might interact with sildenafil, and assess whether treatment goals are being met. Your prescriber will also check for any changes in your overall health status that might affect treatment suitability.

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.
