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 Your Sildenafil Treatment Response

What to Expect During Your First Month

When starting sildenafil tablets, whether generic or branded Viagra, most men begin with a 50mg dose. The medication typically takes 30-60 minutes to become effective, though this can vary based on individual factors including food intake and metabolism. Effects may last 4-6 hours, though this doesn't mean maintaining an erection for this duration - sexual stimulation is still required for the medication to work.

Key Monitoring Points

Track several important factors to help your prescriber optimise your treatment. Note the timing between taking your tablet and first noticing effects. Record whether you can achieve and maintain erections suitable for sexual activity. Document any side effects such as headaches, facial flushing, or nasal congestion. These are common and often mild but should be monitored.

When to Consider Dose Adjustments

If your initial 50mg dose proves insufficient after trying it on at least 4-6 separate occasions, your prescriber may suggest increasing to 100mg. Conversely, if you experience troublesome side effects, a reduction to 25mg might be appropriate. Never adjust your dose without consulting your healthcare provider first.

Factors That May Affect Effectiveness

Several elements can influence how well sildenafil works. Large or fatty meals taken close to dosing time may delay onset. Excessive alcohol consumption can reduce effectiveness and increase side effect risk. Stress, anxiety, and relationship issues may also impact treatment success. Your overall cardiovascular health plays a crucial role in how well the medication works.

When to Seek Medical Advice

Contact your prescriber if you experience no improvement after trying the medication properly on multiple occasions. Seek immediate medical attention for erections lasting over 4 hours, sudden vision or hearing changes, or severe chest pain. Regular follow-up appointments help ensure your treatment remains safe and effective.

Recording Your Progress

Keep a simple treatment diary noting dates, dosage taken, timing, effectiveness rating, and any side effects. This information proves invaluable during consultations and helps identify patterns that might inform treatment adjustments. Both generic sildenafil and Viagra can be monitored using the same approach, as they contain identical active ingredients.

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.
