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 Effectively

Initial Monitoring Period

The first few weeks of Viagra treatment require careful observation. NHS guidance suggests tracking your response to at least 4-6 doses before making dosage adjustments. Keep a simple record noting timing of administration, onset of effects, duration, and any side effects experienced. This information helps your prescriber determine if your current dose is optimal or requires modification.

What to Track During Treatment

Effective monitoring involves recording several key factors. Note the time between taking your medication and onset of effects - typically 30-60 minutes for most patients. Document the duration of effectiveness and any factors that may influence response, such as food intake or alcohol consumption. Both branded Viagra and generic sildenafil work identically, so monitoring approaches remain consistent regardless of your choice at checkout.

Side Effect Monitoring

Common side effects include headache, facial flushing, indigestion, and nasal congestion. These typically mild symptoms often improve with continued use. However, monitor for more serious effects such as persistent erections lasting over 4 hours, sudden vision changes, or chest pain during sexual activity. Any concerning symptoms should be reported to your healthcare provider immediately.

When to Contact Your Prescriber

Regular review appointments help optimise your treatment. Contact your prescriber if you experience reduced effectiveness after initial success, persistent side effects that don't improve, or if you develop any new health conditions. Changes in other medications may also affect Viagra's effectiveness and safety profile.

Long-term Treatment Monitoring

NHS guidelines recommend periodic reviews to assess ongoing treatment needs. Your prescriber may adjust dosage between 25mg, 50mg, or 100mg based on your response patterns. Some patients benefit from switching between branded Viagra and generic sildenafil options, though the active ingredient remains identical. EverydayMeds' clinical team provides ongoing support throughout your treatment journey.

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.
