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 Our Online Consultation Process Works

Understanding What Viagra Does Through Professional Online Assessment

Viagra contains sildenafil citrate, a PDE5 inhibitor that increases blood flow to the penis when sexually stimulated. Through EverydayMeds' online consultation, our UK-licensed prescribers evaluate whether Viagra is suitable for your specific situation and explain exactly how it works for your individual needs. The medication blocks the enzyme phosphodiesterase type 5, allowing blood vessels to relax and improve circulation during arousal. This process requires sexual stimulation to be effective - Viagra doesn't cause automatic erections but supports natural response when aroused.

Our online clinical assessment determines the appropriate starting dose, typically 50mg, though this may be adjusted to 25mg or 100mg based on your medical history and requirements. The consultation process ensures you understand that Viagra's effects begin within 30-60 minutes and can last 4-6 hours, though this doesn't mean erections persist throughout this period.

Comprehensive Medical Evaluation Through Digital Consultation

EverydayMeds' online consultation involves completing a detailed medical questionnaire reviewed by GMC-registered prescribers. This assessment evaluates your cardiovascular health, current medications, and medical history to ensure Viagra is safe and appropriate for you. The digital consultation process identifies any contraindications, such as nitrate medications or recent cardiovascular events, which would make Viagra unsuitable.

During the online assessment, prescribers evaluate potential drug interactions and side effects specific to your circumstances. Common side effects like headaches, facial flushing, and indigestion are discussed, along with guidance on managing these effects. The consultation also covers serious but rare side effects requiring immediate medical attention, such as priapism or sudden vision changes.

Choosing Between Branded Viagra and Generic Sildenafil

Our online consultation service offers flexibility at checkout, allowing you to choose between branded Viagra and generic sildenafil. Both contain identical active ingredients and demonstrate the same effectiveness and safety profile. The prescriber explains during consultation that sildenafil is the generic version, offering significant cost savings whilst maintaining the same therapeutic benefits as branded Viagra.

Through the online assessment, you'll learn that both options work identically - increasing blood flow to support erections during sexual arousal. The choice between branded and generic often comes down to personal preference and budget considerations, with many patients opting for the cost-effective generic alternative after understanding the equivalence through consultation.

Dosage Guidance and Usage Instructions

The online consultation determines your optimal starting dose and provides comprehensive usage instructions. Prescribers typically recommend beginning with 50mg taken 30-60 minutes before sexual activity, with the option to adjust to 25mg if side effects occur or increase to 100mg if the initial dose proves insufficient. The consultation emphasises the maximum dose frequency of once per 24-hour period.

During the digital assessment, prescribers explain how food affects Viagra's performance, noting that high-fat meals may delay onset of action. The consultation covers alcohol interaction guidance, explaining that moderate consumption is generally acceptable but excessive drinking may reduce effectiveness and worsen side effects like dizziness.

Safety Monitoring and Ongoing Support

EverydayMeds' online consultation service includes ongoing clinical support and safety monitoring. The digital platform allows you to contact prescribers with questions about how Viagra is working for you or any concerns about side effects. This continued care ensures optimal treatment outcomes and immediate professional guidance when needed.

The consultation process includes clear instructions on when to seek immediate medical attention, such as experiencing chest pain during sexual activity or erections lasting longer than four hours. Prescribers provide comprehensive safety information during the online assessment, ensuring you're fully informed about responsible medication use.

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.
