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 Branded vs Generic ED Treatments

Active Ingredient: The Foundation of Effectiveness

The most important factor when comparing Viagra and generic sildenafil is that both medications contain exactly the same active ingredient: sildenafil citrate. This PDE5 inhibitor works by increasing blood flow to the penis during sexual arousal, helping men achieve and maintain erections suitable for sexual activity. Whether you choose branded Viagra or generic sildenafil, you receive the same therapeutic effect from the same proven compound that has helped millions of men worldwide.

Regulatory Standards and Quality Assurance

Generic sildenafil available through UK pharmacies must meet identical regulatory standards to branded Viagra. The Medicines and Healthcare products Regulatory Agency (MHRA) ensures that generic medications demonstrate bioequivalence to the original branded version. This means generic sildenafil must be absorbed into the bloodstream at the same rate and to the same extent as Pfizer's Viagra. Manufacturing facilities producing both branded and generic versions undergo regular inspections and must comply with Good Manufacturing Practice guidelines.

Cost Considerations for Long-term Treatment

One of the most significant differences between Viagra and generic sildenafil lies in pricing. Generic alternatives typically cost considerably less than branded Viagra while providing equivalent therapeutic benefits. For men requiring ongoing ED treatment, this cost difference can represent substantial savings over time. At EverydayMeds, we understand that treatment affordability affects accessibility, which is why we offer both options so patients can choose based on their individual circumstances and preferences.

Available Strengths and Dosing Options

Both Viagra and generic sildenafil are available in the same three strengths: 25mg, 50mg, and 100mg tablets. The typical starting dose is 50mg, taken approximately 30-60 minutes before anticipated sexual activity. Depending on individual response and tolerability, the dose may be adjusted to 25mg for those experiencing side effects or increased to 100mg if the initial dose proves insufficient. Regardless of whether you choose branded or generic, the same dosing guidelines apply, with a maximum of one dose per 24-hour period.

Clinical Effectiveness and Patient Outcomes

Multiple studies have demonstrated that generic sildenafil produces equivalent clinical outcomes to branded Viagra. The onset of action typically occurs within 30-60 minutes for both formulations, with effects potentially lasting 4-6 hours. This timeframe represents the period during which the medication can facilitate erections with sexual stimulation, not the duration of any single erection. Patient satisfaction rates and effectiveness measures show no significant differences between branded and generic formulations when used according to clinical guidelines.

Making Your Choice at EverydayMeds

When completing your consultation with EverydayMeds, you will have the opportunity to choose between Viagra and generic sildenafil during the checkout process. Some patients prefer branded Viagra due to familiarity or personal preference, while others opt for generic sildenafil to maximise value without compromising on quality. Our UK-licensed prescribers can provide guidance based on your individual clinical assessment, helping ensure you receive appropriate treatment regardless of which option you select.

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.
