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.

What to Expect When Starting Sildenafil Treatment

Understanding How Sildenafil Works

Sildenafil citrate belongs to a class of medicines called PDE5 inhibitors, which work by increasing blood flow to the penis during sexual arousal. It's important to understand that sildenafil doesn't cause automatic erections - sexual stimulation is still required for the medication to be effective. The medicine blocks an enzyme that restricts blood flow, allowing natural erectile function to occur more easily.

Choosing Your First Dose

Most men start with a 50mg dose of sildenafil, which provides an effective balance between efficacy and tolerability. Your prescriber may recommend starting with 25mg if you're over 65, have certain medical conditions, or take specific medications. The dose can be adjusted up to 100mg or down to 25mg based on how well it works and any side effects experienced. At EverydayMeds, both generic sildenafil and branded Viagra are available in all three strengths, giving you flexibility in your treatment choice.

Timing and Administration

Take your sildenafil tablet approximately 30-60 minutes before you plan to be sexually active. The medication works best on an empty stomach, as food - particularly fatty meals - can delay its onset of action. Swallow the tablet whole with water, and remember that you should never take more than one dose within a 24-hour period, regardless of whether the first dose was effective.

What to Expect During Your First Experience

During your first time using sildenafil, you may notice the effects beginning within 30-45 minutes, though this can vary between individuals. The medication's effects can last for 4-6 hours, but this doesn't mean you'll have an erection for this entire time. Instead, it means you may find it easier to achieve and maintain an erection during this window when sexually aroused. Some men find the medication works better on subsequent occasions as anxiety about performance decreases.

Managing Potential Side Effects

Common side effects when starting sildenafil include headaches, facial flushing, indigestion, and nasal congestion. These are usually mild and temporary, often improving as your body adjusts to the medication. If you experience dizziness, avoid driving or operating machinery. Serious side effects are rare but require immediate medical attention, including prolonged erections lasting over 4 hours, sudden vision or hearing loss, or chest pain.

Lifestyle Factors That Affect Effectiveness

Several factors can influence how well sildenafil works during your first experience. Alcohol can reduce the medication's effectiveness and increase the risk of side effects, so limit consumption. Stress and anxiety about performance can also impact results - remember that some men need several attempts before achieving optimal results. Maintaining good overall health through regular exercise and a balanced diet can improve your response to ED treatment.

When to Contact Your Prescriber

Contact your healthcare provider if the initial 50mg dose doesn't provide adequate results after trying it on at least four separate occasions. They may adjust your dose or suggest alternative approaches. Also seek advice if you experience bothersome side effects or have concerns about the medication's suitability. At EverydayMeds, our UK-licensed prescribers are available to discuss your treatment and make necessary adjustments to ensure optimal outcomes.

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.
