What is it about alcoholic beer that can interact with antidepressants and then does non alcoholic beer carry the same risk?

Increased side effects

The side effects you might experience from antidepressants is magnified if you drink alcohol along with them.

Some of these include

  • headaches.
  • nausea.
  • insomnia.
  • drowsiness.
  • dry mouth.
  • dizziness.
  • loss of appetite.
  • constipation

Not only will the antidepressant side effects increase, so will the side effects of any other medications your are taking such as sleeping or pain medication.

Increased drowsiness

Some of the antidepressants can directly cause drowsiness, as will alcohol. When taken together this can be magnified and become more intense.

Depression risk

You are prescribed antidepressant medication in order to boost your mood and lift depression. Alcohol is a known depressant so will counteract any of the benefits of the medication you are prescribed. 

Blood pressure spike on MAOIs

One of the most dangerous interactions between alcohol and antidepressants is with a particular set of medications called MAOIs (monoamine oxidase inhibitors).

Alcohol can cause a dangerous spike in blood pressure with these medications so it is best avoided.

Decreased alertness or sharpness

Needless to say, alcohol dulls your senses and mental sharpness. This is magnified when taken with antidepressants and you may feel like you are in a fog or can’t concentration or make decisions.

Will alcohol free beer cause the complications alcoholic beer does?

The biggest difference between alcoholic and alcohol free beer is the amount of alcohol in each. As we have seen above, alcohol free beer has about 1% the amount of alcohol or less than alcoholic beers. 

It is therefore a good assumption that would would be able to drink up to x100 as many alcohol free beers as you would alcoholic beers before you get into any interactions or issues with antidepressants.
