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.

How to Access Viagra Treatment Through EverydayMeds

Start Your Online Consultation Today

Getting Viagra treatment through EverydayMeds is straightforward and discreet. Begin by completing our free online consultation form, which takes just a few minutes. Our UK-licensed prescribers will review your medical history and current medications to determine if Viagra is suitable for you. Once approved, you can choose between Viagra (branded) or Sildenafil (generic) - both containing the same active ingredient, sildenafil citrate.

How Viagra Works in Your Body

Viagra contains sildenafil citrate, which belongs to a group of medicines called PDE5 inhibitors. When you're sexually aroused, your body naturally produces nitric oxide, which increases blood flow to the penis. Viagra works by blocking the PDE5 enzyme that can interfere with this process, helping maintain increased blood flow and supporting your ability to achieve and maintain an erection.

It's important to understand that Viagra doesn't automatically cause an erection - sexual stimulation is still required. The medication typically starts working within 30-60 minutes of taking it, and its effects can last up to 4-6 hours. This doesn't mean your erection will last this long, but rather that you may find it easier to achieve erections during this timeframe when sexually aroused.

Choosing Between Viagra and Sildenafil

At checkout, you can select either Viagra (the branded version) or Sildenafil (the generic alternative). Both contain exactly the same active ingredient and work in the same way. The main difference is cost - Sildenafil is typically more affordable than branded Viagra while providing the same clinical benefits. Many patients choose Sildenafil as a budget-friendly option without compromising on quality or effectiveness.

Dosage and Administration

Viagra is available in 25mg, 50mg, and 100mg strengths. Most men start with 50mg, taken approximately one hour before sexual activity. Your prescriber may adjust this dose based on how well it works for you and any side effects you might experience. Never take more than one dose in 24 hours, and avoid taking Viagra with heavy or fatty meals as this can delay its effectiveness.

Safety Considerations and Medical Review

Our clinical team will carefully review your consultation to ensure Viagra is safe for you. This medication isn't suitable for everyone, particularly men taking nitrate medications for heart conditions, or those with certain cardiovascular conditions. Our prescribers will check for potential drug interactions and assess your overall health before approving treatment.

Discreet Delivery and Ongoing Support

Once your prescription is approved, we'll dispatch your medication in discreet, unmarked packaging. We offer next-day delivery options across the UK, and you can reorder easily when needed. Our customer support team is available if you have any questions about your treatment or need guidance on using Viagra effectively.

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.

How quickly does Viagra work and how long do the effects last?

Both contain the same active ingredient (sildenafil citrate) and work identically. Viagra is the branded version, while Sildenafil is the generic alternative. You can choose either option at checkout, with Sildenafil typically being the more affordable choice.
