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 and Your Treatment Options

What Happens When You Take Viagra for the First Time

Viagra contains the active ingredient sildenafil citrate, which belongs to a class of medicines called PDE5 inhibitors. When you take Viagra for the first time, it typically begins working within 30-60 minutes by increasing blood flow to the penis during sexual arousal. It's important to understand that Viagra doesn't automatically cause an erection - sexual stimulation is still necessary for the medication to be effective.

Starting Doses and What to Expect

Most first-time users begin with a 50mg dose of Viagra, taken approximately one hour before sexual activity. Your prescriber may adjust this to 25mg if you experience side effects, or increase to 100mg if the initial dose proves insufficient. The effects of Viagra can last up to 4-6 hours, though this doesn't mean an erection will persist for this duration. Remember that only one dose should be taken within any 24-hour period.

Branded Viagra vs Generic Sildenafil

At EverydayMeds, you can choose between branded Viagra and generic sildenafil at checkout. Both contain the same active ingredient and work identically, but generic sildenafil offers a more cost-effective option. The choice between branded and generic comes down to personal preference and budget, as both undergo rigorous quality controls and provide the same therapeutic benefits.

Preparing for Your First Dose

Before taking Viagra for the first time, avoid consuming large or fatty meals, as these can delay the medication's onset. Alcohol should be limited, as excessive consumption may reduce effectiveness and increase the risk of side effects such as dizziness or low blood pressure. Plan to take your dose when you're relaxed and not feeling anxious, as stress can impact the medication's effectiveness.

Common First-Time Side Effects

Many first-time users experience mild side effects that typically diminish with continued use. These may include headache, facial flushing, indigestion, or nasal congestion. These effects are generally temporary and resolve within a few hours. If you experience any severe side effects or an erection lasting longer than four hours, seek immediate medical attention.

Safety Considerations and Contraindications

Before prescribing Viagra, our clinicians conduct a thorough assessment to ensure it's safe for you. Viagra is contraindicated for men taking nitrate medications for chest pain, those with severe heart conditions, or recent stroke survivors. Always disclose all medications and health conditions during your consultation to ensure safe treatment.

Getting the Most from Your Treatment

Success with Viagra often improves over time as you become more familiar with how your body responds. Some men find the medication works better on their second or third attempt, particularly as anxiety decreases. Maintain realistic expectations and communicate openly with your healthcare provider about your experience to optimise your treatment plan.

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.
