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.

Viagra 100mg vs Sildenafil: Performance Comparison

What Makes Viagra 100mg Different

Viagra 100mg represents the maximum strength dose of sildenafil citrate available for erectile dysfunction. This blue diamond-shaped tablet contains 100mg of the active ingredient that blocks PDE5 enzymes, increasing blood flow to the penis during sexual arousal. Many men find this strength effective when lower doses haven't provided satisfactory results.

Real-World Effectiveness

Clinical studies show Viagra 100mg helps approximately 80% of men achieve erections suitable for sexual activity. The medication typically begins working within 30-60 minutes, with effects potentially lasting 4-6 hours. However, this doesn't mean an erection lasts this long - sexual stimulation is still required throughout.

Food can significantly impact absorption, particularly fatty meals which may delay onset by up to an hour. Most men report optimal results when taking Viagra 100mg on an empty stomach or after a light meal.

Generic Sildenafil: Identical Results, Lower Cost

Generic sildenafil 100mg contains exactly the same active ingredient as branded Viagra, manufactured to identical pharmaceutical standards. The key difference lies in price - generic versions typically cost 70-80% less than branded Viagra whilst delivering equivalent results.

At EverydayMeds, patients can choose between branded Viagra or generic sildenafil during checkout, both requiring the same clinical assessment. This choice allows you to prioritise either brand familiarity or cost savings based on personal preferences.

Common Side Effects and Management

Viagra 100mg may cause side effects in some users, typically mild and temporary. Common experiences include headaches, facial flushing, nasal congestion, and indigestion. These effects usually diminish as your body adjusts to the medication.

More serious side effects are rare but require immediate medical attention, including prolonged erections lasting over 4 hours, sudden vision changes, or chest pain. The 100mg strength may produce more noticeable side effects compared to lower doses.

Who Should Consider 100mg Strength

Healthcare providers typically prescribe Viagra 100mg for men who haven't achieved satisfactory results with 50mg doses. Starting doses are usually 50mg, adjusted based on effectiveness and tolerance. The maximum recommended frequency is once per 24-hour period.

Men with certain health conditions, including cardiovascular disease, liver problems, or those taking specific medications, may require dose adjustments or alternative treatments. This is why clinical assessment remains essential before starting any sildenafil treatment.

Value Comparison: Branded vs Generic

Choosing between Viagra and generic sildenafil often comes down to personal priorities. Branded Viagra offers the reassurance of the original product with extensive clinical history. Generic sildenafil provides identical therapeutic benefits at a fraction of the cost, making long-term treatment more affordable.

Both options are equally regulated by the MHRA and require prescription through licensed UK pharmacies like EverydayMeds. The clinical assessment process ensures suitability regardless of whether you choose branded or generic options.

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.
