Interaction with Food and Other Compounds

Food
Taking quetiapine with food increases both the absorption and the maximum blood concentration of the drug.1 Problems may arise when individuals switch from taking quetiapine with a meal to taking it on an empty stomach and vice versa. Therefore, people should consistently take quetiapine with a meal to enhance drug actions and to avoid potential problems.

Alcohol
Quetiapine aggravates the adverse effect of alcohol on mental and motor skills, which might have serious consequences.2 Therefore, people taking quetiapine should avoid drinking alcohol, especially when they must stay alert.
