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 the Risks: Alcohol and ED Medication

How Alcohol Affects Viagra and Sildenafil

Both Viagra (branded) and sildenafil (generic) work by relaxing blood vessels to increase blood flow. Alcohol also affects blood vessels and can lower blood pressure. When combined, these effects may be amplified, potentially causing unwanted side effects. EverydayMeds offers both Viagra and the more affordable sildenafil option, with the same safety considerations applying to both medications.

Recommended Alcohol Limits

The patient information leaflet advises limiting alcohol consumption when taking sildenafil-based medications. Healthcare professionals generally recommend no more than 1-2 units of alcohol (equivalent to half a pint of beer or a small glass of wine). Excessive drinking may reduce the medication's effectiveness and increase the likelihood of experiencing side effects such as dizziness, flushing, or headaches.

Potential Side Effects of Mixing

Combining alcohol with Viagra or sildenafil may intensify common side effects including headaches, facial flushing, nasal congestion, and dizziness. More concerning is the potential for a significant drop in blood pressure, which could cause fainting or falls. Some men also report reduced sexual performance when alcohol is consumed alongside ED medication, as alcohol itself can impair sexual function.

Timing Considerations

If you choose to have a small amount of alcohol, consider the timing carefully. Alcohol can delay the absorption of sildenafil, potentially making the medication less predictable in its onset. For optimal results, many patients find it best to avoid alcohol entirely when planning to use their ED medication. Whether you choose Viagra or the generic sildenafil option available through EverydayMeds, consistent timing and avoiding excessive alcohol helps ensure the most reliable results.

When to Seek Medical Advice

Contact a healthcare professional immediately if you experience chest pain, severe dizziness, or fainting after combining alcohol with your ED medication. These could be signs of a dangerous drop in blood pressure. Always inform your prescriber about your alcohol consumption habits during consultations, as this helps them provide the most appropriate treatment recommendations for your individual circumstances.

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.
