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 Dosage

Sildenafil 50mg represents the recommended starting dose for most men experiencing erectile dysfunction. This dosage strength is available in both generic sildenafil and branded Viagra formulations, containing identical active ingredients with equivalent effectiveness. Clinical studies demonstrate that 50mg provides an optimal balance between efficacy and tolerability for the majority of patients.

Complete Dosage Range Available

Sildenafil is available in three dosage strengths: 25mg, 50mg, and 100mg tablets. The 25mg dose is typically reserved for men who experience side effects with higher doses or those taking certain medications that may interact. The 100mg dose may be prescribed if 50mg proves insufficient, though this should only be determined following clinical assessment by a qualified prescriber.

Proper Timing and Administration

Take sildenafil 50mg approximately 30-60 minutes before planned sexual activity. The medication requires sexual arousal to be effective and does not produce automatic erections. Effects typically last 4-6 hours, though this varies between individuals. Fatty meals may delay onset of action, so consider taking on an empty stomach for faster results.

Safety Considerations and Monitoring

Never exceed one tablet within a 24-hour period, regardless of dosage strength. Men taking nitrate medications, those with severe cardiovascular disease, or significant liver impairment should not use sildenafil. Regular monitoring may be recommended for men with underlying health conditions. Always inform your prescriber of any changes to your health status or medications.

Branded vs Generic Options

EverydayMeds provides both Viagra (branded) and sildenafil (generic) options at checkout. Both contain the same active ingredient and demonstrate equivalent effectiveness. Generic sildenafil typically offers cost savings whilst maintaining the same safety profile and therapeutic benefits. Your choice between branded or generic depends on personal preference and budget considerations.

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.
