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 Sildenafil 50mg Compared to Other Strengths

Why 50mg is the Standard Starting Dose

Sildenafil 50mg has been established as the optimal starting dose for most men experiencing erectile dysfunction. This strength typically provides effective results whilst minimising the risk of side effects. Clinical studies demonstrate that 50mg offers a good balance between efficacy and tolerability, making it suitable for the majority of patients beginning ED treatment.

Comparing Sildenafil Dosage Strengths

Sildenafil is available in three strengths: 25mg, 50mg, and 100mg. The 25mg dose may be prescribed for men who experience side effects with higher doses or those taking certain medications that could interact with sildenafil. The 100mg strength might be considered if 50mg proves insufficient, though this should only be adjusted following consultation with a healthcare professional.

Branded Viagra vs Generic Sildenafil

EverydayMeds offers both branded Viagra and generic sildenafil options, allowing patients to choose based on their preferences and budget. Generic sildenafil contains the identical active ingredient as Viagra but typically costs significantly less. Both medications work in exactly the same way, blocking the PDE5 enzyme to improve blood flow to the penis when sexually aroused.

How to Take Sildenafil 50mg Effectively

For optimal results, take sildenafil 50mg approximately 30-60 minutes before sexual activity. The medication works best on an empty stomach, as fatty foods can delay absorption and reduce effectiveness. Remember that sexual stimulation is still required - sildenafil doesn't cause automatic erections but enhances your natural response to arousal.

Dosage Adjustment Considerations

Your prescriber may recommend adjusting your dose based on how well 50mg works for you and whether you experience any side effects. Common side effects include headaches, facial flushing, and indigestion. If these are troublesome, a reduction to 25mg might be suggested. Conversely, if 50mg doesn't provide sufficient improvement, your doctor may consider increasing to 100mg.

Safety and Contraindications

Sildenafil 50mg isn't suitable for everyone. It's particularly important to avoid this medication if you're taking nitrate medications for chest pain, as this combination can cause a dangerous drop in blood pressure. Men with severe heart conditions, recent stroke or heart attack, or certain eye conditions should discuss alternative treatments with their healthcare provider.

Cost Considerations and Value

Generic sildenafil represents excellent value compared to branded alternatives, offering identical therapeutic benefits at a fraction of the cost. This makes ongoing ED treatment more affordable without compromising on quality or effectiveness. Both options undergo rigorous quality testing to ensure they meet UK pharmaceutical standards.

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.
