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 Your Treatment Options

What's the Difference Between Viagra and Generic Sildenafil?

Viagra is the original brand name medication manufactured by Pfizer, containing the active ingredient sildenafil citrate. Generic sildenafil contains the exact same active ingredient but is produced by other licensed pharmaceutical manufacturers once Pfizer's patent expired. Both medications work identically - as PDE5 inhibitors that may help improve blood flow to the penis when sexually aroused.

Quality and Effectiveness Comparison

Generic sildenafil manufactured by MHRA-approved facilities must meet identical quality standards to branded Viagra. The active ingredient, dosage, and therapeutic effects are the same. Clinical studies demonstrate equivalent effectiveness between branded and generic versions when properly manufactured and regulated. Patients can expect similar onset times (30-60 minutes) and duration of effects (4-6 hours) from both options.

Cost Considerations

Generic sildenafil typically costs substantially less than branded Viagra - often 50-80% cheaper while maintaining identical therapeutic benefits. This cost difference exists because generic manufacturers don't need to recoup research and development costs. For patients requiring long-term treatment, choosing generic sildenafil can result in significant savings without compromising treatment quality.

Dosage Options Available

Both Viagra and generic sildenafil are available in 25mg, 50mg, and 100mg strengths. Most patients start with 50mg, taken approximately one hour before sexual activity. Your prescriber may adjust the dosage to 25mg or 100mg based on effectiveness and tolerability. Remember, only one dose should be taken within any 24-hour period, regardless of which option you choose.

Safety Profile and Contraindications

Both medications share identical contraindications and potential side effects. Neither should be taken by patients using nitrate medications, those with severe cardiovascular conditions, or individuals with certain medical contraindications. Common side effects may include headaches, flushing, or nasal congestion. Always complete a thorough clinical assessment before starting treatment.

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.
