Drug interactions
Qusel should be cautiously co-prescribed with other centrally acting drugs. Since quseL (Quetiapine) may cause hypotension, it may potentiate the effects of antihypertensive agents.
Qusel (Quetiapine) may antagonize the effects of levodopa and dopamine agonists. Since co-administration of Quetiapine (qusel) and hepatic enzyme inducer e.g., phenytoni, carbamazepine, barbiturates, rifampin & glucocorticoids, increases the mean oral clearance of QUSEL, higher dose of qusel may be required to be given in such patients to ensure optimum efficacy in schizophrenia.
