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.

Complete Guide: Taking Viagra Step by Step

Standard Dosing Instructions

The typical starting dose for Viagra is 50mg, taken approximately 30-60 minutes before anticipated sexual activity. Your prescriber may adjust this to 25mg if you experience side effects, or increase to 100mg if the standard dose proves insufficient. It's crucial to never exceed one tablet within any 24-hour period, regardless of the strength prescribed.

Timing and Food Considerations

Viagra works most effectively when taken on an empty stomach. Fatty or heavy meals can significantly delay the medication's onset of action, potentially extending the usual 30-60 minute timeframe. The effects typically last 4-6 hours, though this doesn't mean you'll maintain an erection for this duration - sexual stimulation remains necessary for the medication to work.

What to Expect When Taking Viagra

Viagra is a PDE5 inhibitor that increases blood flow to the penis during sexual arousal. The medication doesn't cause spontaneous erections; physical or psychological sexual stimulation is still required. Most men notice improved erectile function within 30-60 minutes of taking the tablet, with peak effectiveness occurring around 1-2 hours after consumption.

Important Safety Considerations

Never take Viagra if you're using nitrate medications such as GTN spray or isosorbide tablets, as this combination can cause dangerous drops in blood pressure. Inform your prescriber about all medications you're taking, including over-the-counter supplements. If you experience chest pain during sexual activity, stop immediately and seek medical attention.

Choosing Between Viagra and Sildenafil

EverydayMeds offers both branded Viagra and generic sildenafil at checkout. Both contain the same active ingredient (sildenafil citrate) and work identically. The generic option provides the same effectiveness at a lower cost, whilst some patients prefer the branded version. Your clinical assessment will determine suitability for either option.

Monitoring Your Response

Keep track of how well the medication works for you and any side effects experienced. Common mild side effects may include headaches, facial flushing, or nasal congestion. If you experience prolonged erections lasting over 4 hours, severe vision changes, or chest pain, seek immediate medical attention. Your prescriber can adjust dosing based on your response and tolerability.

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.
