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.

Optimal Timing for Sildenafil 50mg

Sildenafil 50mg should be taken 30-60 minutes before you plan to engage in sexual activity. This timeframe allows the medication to be absorbed and become effective. The tablet works by increasing blood flow when you become sexually aroused - it will not cause an automatic erection without stimulation.

Frequency and Duration Guidelines

Never take more than one sildenafil 50mg tablet in a 24-hour period, regardless of whether you choose the generic version or branded Viagra option available through EverydayMeds. The effects typically last 4-6 hours, though this varies between individuals. This does not mean an erection will last this long - rather, it indicates the window during which the medication may help when you become aroused.

Food and Drink Considerations

Food can significantly impact sildenafil's effectiveness. Heavy or fatty meals may delay absorption by up to an hour. For optimal results, take sildenafil on an empty stomach or after a light meal. Moderate alcohol consumption is generally acceptable, but excessive drinking may reduce the medication's effectiveness and increase side effect risks.

What to Expect After Taking Sildenafil

Most men notice sildenafil 50mg becomes effective within 30-60 minutes. Some may respond faster, whilst others might need up to 90 minutes. If the 50mg dose proves insufficient, your EverydayMeds prescriber may adjust your dosage to 25mg (if side effects occur) or 100mg (if 50mg is well-tolerated but insufficiently effective).

Important Safety Reminders

Always follow your prescriber's specific instructions. If you experience an erection lasting over 4 hours, seek immediate medical attention. Common side effects include headaches, facial flushing, and indigestion. These typically resolve as the medication leaves your system. Contact your healthcare provider if you experience chest pain, dizziness, or other concerning symptoms.

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.
