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 Viagra: Your First Treatment Journey

What is Viagra and How Does It Work?

Viagra contains the active ingredient sildenafil citrate, which belongs to a class of medications called PDE5 inhibitors. When you become sexually aroused, Viagra works by increasing blood flow to the penis, helping you achieve and maintain an erection. It's important to understand that Viagra doesn't cause automatic erections - sexual stimulation is still necessary for the medication to be effective.

Choosing Between Viagra and Generic Sildenafil

At EverydayMeds, patients can choose between branded Viagra and generic sildenafil during checkout. Both contain the same active ingredient and work identically, with generic sildenafil typically being the more cost-effective option. The choice often comes down to personal preference and budget considerations, as both undergo the same rigorous clinical assessment process.

First-Time Dosage and Timing

Most men start with a 50mg dose, taken approximately 30-60 minutes before planned sexual activity. Your prescriber may recommend starting with 25mg if you have certain health conditions or take specific medications. Never exceed one dose within 24 hours, regardless of the strength prescribed. Food, particularly fatty meals, can delay how quickly Viagra takes effect.

What to Expect During Your First Experience

First-time users often wonder what to expect when taking Viagra. The medication typically begins working within 30-60 minutes, though some men may notice effects sooner or later. You might experience mild side effects such as headache, facial flushing, or slight changes in vision. These are generally temporary and mild. The effects can last up to 4-6 hours, providing a window of opportunity for sexual activity.

Safety Considerations and Contraindications

Before prescribing Viagra, our clinicians will assess your medical history and current medications. Viagra isn't suitable for everyone - particularly men taking nitrate medications for heart conditions, as this combination can cause dangerous drops in blood pressure. Men with severe heart disease, recent heart attacks or strokes, or severe liver problems may also be advised against using Viagra.

Managing Side Effects

Common side effects include headaches, indigestion, facial flushing, and nasal congestion. These typically resolve within a few hours. If you experience persistent or severe side effects, contact your healthcare provider. Rare but serious side effects requiring immediate medical attention include prolonged erections lasting over four hours or sudden vision or hearing loss.

Getting Your Prescription Through EverydayMeds

Our streamlined process begins with a comprehensive online consultation reviewed by UK-licensed prescribers. This clinical assessment evaluates your suitability for treatment, considering your medical history, current medications, and specific needs. Once approved, you can choose between branded Viagra or generic sildenafil, with discreet delivery to your preferred address.

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.
