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 Sildenafil Side Effects for Safe Treatment

Common Side Effects of Sildenafil

Most men tolerate sildenafil well, but like all medications, it may cause side effects. Common side effects typically affect 1 in 10 men and include headaches, facial flushing, indigestion, nasal congestion, and dizziness. These effects are usually mild and temporary, often lasting only a few hours. Visual disturbances such as colour tinge or increased light sensitivity may also occur but are generally not serious.

Less Common but Important Side Effects

Some men may experience less frequent side effects including back pain, muscle aches, nausea, or skin rash. These typically affect fewer than 1 in 100 men. Prolonged erections lasting more than 4 hours (priapism) are rare but require immediate medical attention. Changes in blood pressure may occur, particularly in men taking other medications that affect cardiovascular function.

When to Seek Medical Advice

Whilst serious side effects are uncommon, certain symptoms require prompt medical attention. Sudden vision or hearing loss, chest pain during sexual activity, or severe allergic reactions warrant immediate consultation with a healthcare professional. Men with heart conditions should be particularly vigilant about any cardiovascular symptoms whilst using sildenafil.

Accessing Treatment Through EverydayMeds

Our streamlined online consultation process allows you to access sildenafil treatment quickly and safely. After completing a comprehensive medical questionnaire, a UK-licensed prescriber reviews your case within hours. You can choose between generic sildenafil for cost-effectiveness or branded Viagra if you prefer the original formulation - both options are available at checkout.

Fast Delivery Options for Your Treatment

Once approved, your treatment ships immediately with various delivery options available. Next-day delivery ensures you receive your medication promptly, whilst our discreet packaging maintains complete privacy. All orders include detailed information about proper usage, potential side effects, and emergency contact information should concerns arise during treatment.

Minimising Side Effects

Taking sildenafil correctly helps reduce the likelihood of side effects. Avoid alcohol excess, heavy meals before taking the medication, and never exceed one tablet within 24 hours. Starting with the lowest effective dose, typically 50mg, allows assessment of individual tolerance. Your prescriber may adjust the dosage based on effectiveness and any side effects experienced during initial treatment.

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.
