Alcohol and High Blood Pressure
While drinking alcohol in moderation is usually fine, consuming too much can make hypertension worse. Moderate drinking usually means one drink a day for women or two drinks a day for men. People who drink alcohol while taking high blood pressure medicine should check with their doctor, since alcohol can have an adverse impact on the medicine's effectiveness.
High Blood Pressure and Alcohol: An Overview
People with high blood pressure (hypertension) often wonder if it is okay to drink alcohol. In many cases, drinking alcohol is fine for someone with high blood pressure -- but in moderation.

What Is Moderate Drinking?
When healthcare providers recommend "moderate" drinking, they mean one drink a day for women; two drinks a day for men. Because the alcohol content in drinks can vary, what counts as one drink also varies. When healthcare providers talk about one drink, they are referring to one of the following examples:
- 12 ounces of beer
- 5 ounces of wine
- 1½ ounces of 80-proof whiskey or 1 ounce of 100-proof spirits.
Effects of Alcohol on High Blood Pressure
If a person is regularly drinking more than a moderate amount of alcohol, reducing consumption will usually lower blood pressure. The amount the blood pressure drops will vary, based on a number of factors, including:
- How much the person drank
- His or her age
- Current blood pressure
- Other medical conditions.
On average, when heavy drinkers reduce their alcohol consumption to a moderate level, systolic blood pressure can drop by 2 to 4 points and diastolic blood pressure by 1 to 2 points.
