Alcohol and Erectile Dysfunction: What You Should Know

If you’re experiencing erectile dysfunction (ED), you may be wondering what the causes are and whether changes to your lifestyle, such as cutting back on your alcohol use, can help. Likewise, if you’re considering a treatment for ED or have already started one, you may be curious to learn more about whether or not it’s safe to use it with alcohol.

In this article we’ll take a look at the influence of alcohol on sexual performance, and explore whether there are any potential health risks of mixing it with erectile dysfunction medications.

Article Summary:

• Erectile dysfunction is the inability to achieve or maintain an erection that's firm enough for penetrative sex. It can happen with or without alcohol use.
• Alcohol consumption is one of many factors that can cause you to have weaker erections.
• For best results, it's recommended to limit your alcohol intake if you're using erectile dysfunction treatment. This will help to prevent complications or adverse effects.

What is erectile dysfunction?

Erectile dysfunction is the inability to achieve or maintain an erection that's firm enough for penetrative sex. This can be caused by both physical and emotional factors, or may indicate an underlying health issue. [1]

There are a range of treatments that can help, and which one is right for you may depend on the cause of your erectile dysfunction. These could include lifestyle changes, therapy, or even medical procedures. But there are also medications you can try, often available in a tablet form, to help improve your performance in the bedroom.

How does alcohol consumption affect erections?

You may have heard of the informal term 'whiskey dick’, which refers to the difficulty some men have in achieving or maintaining an erection after drinking alcohol (not just whiskey, as the name suggests).

But there’s truth behind the crude phrase, because drinking alcohol can affect erections in both the short and long term. That's because it has an immediate effect on the body, and can also impact your health over time.

Alcohol is what's known as a central nervous system depressant. This means it slows the brain and spinal signals that help to trigger and maintain an erection. While it can help you feel less inhibited and more relaxed, it can also make your body slower to respond to sexual arousal.

When you're aroused, signals travel from your brain to your penis to tell the penile blood vessels to open. Alcohol slows those signals down, interfering with the nerve communication that's necessary to achieve an erection. Nitric oxide is also an important factor, because it helps to relax the blood vessels so that there’s more blood flow into the erectile tissue. Alcohol has been linked to changes in nitric oxide metabolism and production, which can weaken that response. [2]

Indirectly, alcohol can also impact erection quality by affecting hydration and cardiovascular health, while excess alcohol use has also been shown to contribute to premature ejaculation. [3]

There are psychological factors to consider too. Because it can lower inhibitions, alcohol can give you 'liquid courage' or a misleading sense of confidence, only to then find you can’t maintain an erection. And if it happens more than once, it could undermine sexual confidence and increase anxiety about your performance.

Acute or chronic: Temporary impairment vs. long-term damage

Drinking too much alcohol in one night might cause a temporary reduction in your ability to get and maintain an erection, while it's still in your system. But chronic heavy drinking or alcohol abuse can cause longer-lasting damage to the nerves, blood vessels and hormone systems involved in erections. For example, long-term alcohol use can lower testosterone production, which is vital to support libido and sexual function. [4]

If you’re struggling with drinking too much alcohol, long term alcohol abuse or using recreational drugs, speak to your GP or healthcare to seek support.

What are erectile dysfunction treatments and how do they work?

The good news is, there are a number of medications that are designed to help improve sexual performance. They work by relaxing the blood vessels and improving blood flow in the body. By increasing blood flow to the penis, they make it easier for you to achieve and maintain an erection when you’re aroused. [5]

Some ED medicines are also used for other conditions, including benign prostatic hyperplasia (enlarged prostate) and pulmonary arterial hypertension (high blood pressure in the lungs). [6]

What are the potential risks of mixing ED treatments and alcohol?

As explained above, alcohol can negatively impact your sexual performance, so consuming it may increase your risk of erectile dysfunction. [7] Heavy drinking is always advised against, as excess alcohol can harm your health, but even moderate drinking can be a factor in sexual dysfunction.

One alcoholic beverage is unlikely to impact the results of an erectile dysfunction treatment, but drinking alcohol alongside your medication can lead to adverse effects, such as a drop in blood pressure.

That’s because they both lower blood pressure, so when taken together it can result in a sudden dip. This can lead to symptoms like dizziness, headaches, and nausea. [5]

If you have underlying heart disease, combining ED treatments with alcohol could also increase your risk of serious cardiovascular issues. [8]

Another rare risk of some ED treatments is prolonged erection (priapism), which could become more likely when drinking alcohol. If you experience a painful or prolonged erection (more than 4 hours) when taking it, either with or without alcohol, it’s essential to seek prompt medical attention.

To reduce these risks, stick to alcohol in moderation or avoid drinking altogether when using erectile dysfunction medication.

Lifestyle tips for safe use

For the best results when using ED treatments, remember the following tips:

• Watch your alcohol intake: Limit excessive alcohol consumption to prevent complications, such as a sudden drop in blood pressure or other adverse effects.
• Avoid consuming grapefruit products: Grapefruit juice can alter how your medication is absorbed, changing its effectiveness.
• Stick to a healthy lifestyle: As well as reducing your alcohol use, regular exercise, a balanced diet, and reduced stress could support your sexual performance.
• Be aware of drug interactions: Some ED treatments can interact with other medications, which could lead to adverse effects. Speak with your healthcare provider to discuss these risks, especially if you’re taking blood pressure medication.
• Always speak to a trusted healthcare provider about any medical conditions, medications, or supplements you’re taking.
