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 Safety for Partners

How Safe Is Viagra When Prescribed Correctly?

Viagra has been prescribed to millions of men worldwide since 1998, with extensive safety data demonstrating it's generally well-tolerated when used as directed. The medication undergoes rigorous clinical assessment before prescription, ensuring it's suitable for each individual's health profile. At EverydayMeds, UK-licensed prescribers evaluate medical history, current medications, and cardiovascular health before approving treatment.

Common Side Effects Partners Should Know

Most Viagra side effects are mild and temporary. Common effects include headaches (affecting around 16% of users), facial flushing, indigestion, and nasal congestion. These typically resolve within a few hours as the medication leaves the system. Visual disturbances, such as slight colour changes or increased light sensitivity, occur in fewer than 3% of users and are generally harmless.

When Viagra May Not Be Safe

Certain health conditions and medications make Viagra unsuitable. Men taking nitrate medications for heart conditions cannot safely use Viagra due to dangerous blood pressure interactions. Those with severe heart disease, recent stroke, or certain eye conditions require careful evaluation. This is why professional medical assessment is essential - our prescribers identify potential risks before prescribing either Viagra or sildenafil.

Cardiovascular Safety Considerations

Research shows that for most men with stable cardiovascular health, Viagra doesn't significantly increase heart attack or stroke risk. However, sexual activity itself can increase cardiovascular demand. Our clinical team assesses whether patients are healthy enough for sexual activity, following established guidelines. Men with controlled blood pressure, stable angina, or mild heart conditions may still be suitable candidates after proper evaluation.

Choosing Between Viagra and Generic Sildenafil

Both branded Viagra and generic sildenafil contain identical active ingredients and have the same safety profile. The choice often comes down to personal preference and cost considerations. Generic sildenafil offers the same effectiveness and safety at a lower price point, while some patients prefer the familiarity of the Viagra brand. EverydayMeds provides both options, allowing patients to choose what works best for their situation during the checkout process.

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.
