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 Viagra Side Effects Assessment Works

Understanding Viagra Side Effects Before Treatment

Before prescribing Viagra, EverydayMeds conducts a thorough eligibility check specifically designed to identify potential side effects and contraindications. Our assessment evaluates your cardiovascular health, current medications, and medical history to ensure Viagra is safe for you. Common side effects include headaches, facial flushing, indigestion, and nasal congestion, but our prescribers help determine if you're at higher risk for these reactions.

The eligibility process screens for dangerous drug interactions, particularly with nitrates and blood pressure medications, which can cause serious side effects. Our UK-licensed clinicians review your responses to identify any red flags that might indicate increased side effect risk or contraindications to treatment.

Personalised Side Effect Risk Assessment

During your Viagra eligibility check, we assess individual factors that influence side effect likelihood. Age, underlying health conditions, and concurrent medications all affect how your body processes Viagra. Men with cardiovascular conditions may experience more pronounced blood pressure effects, whilst those taking certain medications face interaction risks.

Our assessment includes screening for conditions that increase serious side effect risk, such as recent heart attack, stroke, or severe liver problems. We also evaluate your suitability for different Viagra dosages - starting with 25mg, 50mg, or 100mg based on your profile to minimise side effects whilst maintaining effectiveness.

Drug Interaction Screening for Safety

A crucial component of our eligibility check involves comprehensive drug interaction screening. Viagra can cause dangerous interactions with nitrates, alpha-blockers, and certain antifungals or antibiotics. Our assessment identifies these risks before prescribing, preventing potentially serious side effects.

We screen for recreational drug use, particularly "poppers" containing nitrates, which can cause life-threatening blood pressure drops when combined with Viagra. The assessment also evaluates alcohol consumption patterns, as excessive drinking can worsen Viagra's side effects and reduce effectiveness.

Managing Side Effects Through Proper Dosing

Following successful eligibility assessment, our prescribers recommend optimal Viagra dosing to minimise side effects. Starting doses are typically 50mg, but may be adjusted to 25mg for those at higher side effect risk, or increased to 100mg if needed. This personalised approach reduces adverse reactions whilst maintaining treatment efficacy.

We provide detailed guidance on timing, food interactions, and lifestyle factors that influence side effects. Taking Viagra on an empty stomach reduces gastrointestinal side effects, whilst avoiding grapefruit juice prevents drug level fluctuations that could increase adverse reactions.

Ongoing Side Effect Monitoring and Support

Our eligibility check establishes baseline health parameters for ongoing side effect monitoring. We provide clear guidance on which side effects are normal and temporary versus those requiring immediate medical attention. Serious side effects like priapism, sudden vision loss, or chest pain during sexual activity require emergency care.

EverydayMeds offers both branded Viagra and generic Sildenafil following your eligibility assessment. Both contain identical active ingredients with the same side effect profiles, allowing you to choose based on preference and budget whilst maintaining the same safety standards and clinical oversight.

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.
