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.
