Drug Interactions
Using quetiapine with alcohol can make you feel more drowsy and cause low blood pressure when standing up. Certain medications, like phenytoin and carbamazepine (which boost CYP3A4 activity), can lower the amount of quetiapine in your blood. Others, like ketoconazole and erythromycin (which block CYP3A4), can raise its levels in your blood.
Contraindications
Quetiapine should not be used by people who are allergic to it or any of its ingredients. It is also not safe for anyone with severe central nervous system (CNS) depression, bone marrow suppression, or who is in a coma.
Mode of actions
Quetiapine works by blocking several types of receptors in the brain, including serotonin (5-HT1A and 5-HT2), dopamine (D1 and D2), histamine (H1), and adrenergic (alpha-1 and alpha-2) receptors. It is commonly used to treat conditions like schizophrenia and bipolar disorder.
