What’s the best guidance on safe drinking?

Drink within the limits

Because of the way in which alcohol affects the body there is some general health guidance on weekly limits of alcohol which are considered safe for males and females. This guidance is based on being in general good health, not pregnant and not drinking whilst taking medicines.  

However, if just a quarter of the recommended weekly amount is drunk over a matter of hours, this is more likely to be harmful. Recent guidance encourages taking a break of 48 hours or having 2 days alcohol-free each week.

    3 to 4 units per day. A guide limit of 21 units or less per week

  • Safe limits for women

    2-3 units per day. A guide limit of 14 units or less per week


If you are pregnant or trying to conceive the safest option is to avoid drinking alcohol altogether, especially in the first 3 months. If you choose to drink, don’t drink more than 1-2 units once or twice a week. Binge drinking or getting drunk is especially harmful to the baby.

Know your units

With so many different drinks and glass sizes it's easy to get confused about how many units are in your drink. Try the units calculator to quickly calculate units in your favourite drink and download a drinks diary to track your drinking over a week.

The average adult body can process one unit of alcohol in an hour, leaving, in theory, little or no alcohol in the blood (although this will vary from person to person).

Visit the NHS Health Choices for more information on calculating your units.
