Mostly...: ...Because any medicine that has a relaxing or sleepy effect can, in combination with alcohol, cause you to literally forget to breathe.

Very good reasons: In drugs that are central nervous system depressants, alcohol can increase their effects, sometimes dramatically, and result in overdose. With antibiotics, alcohol interferes with the body's ability to fight infection. Alcohol has many drug interactions, where it can increase or decrease the effectiveness of a particular drug, either causing more toxic effects or reducing the benefits.
