Hepatic Enzyme Inducers: Hepatic enzyme inducers such as Carbamazepine, Phenytoin, and Valproate may interact with flunarizine by increasing its metabolism; an increase in dosage of FLUDAN CAPSULES may be required.
CNS Depressants: FLUDAN CAPSULES may enhance the sedative effects of CNS depressants including alcohol, barbiturates, hypnotics, opioid analgesic, anxiolytic sedative and antipsychotics.
Antimuscarinic Drugs: FLUDAN CAPSULES have an additive antimuscarinic action with other antimuscarinic drugs, such as atropine and some antidepressants (both tricyclics and MAOIs).
