Drug Interactions
May lead to additive antipsychotic fraction exposure w/ paliperidone. Higher incidence of mortality w/ thiazide diuretics eg, furosemide. Increased risk of sedation w/ centrally-acting drugs (eg, opiates, antihistamines, benzodiazepine) & alcohol. May enhance effects of drugs w/ BP lowering effects. May antagonize effects of levodopa & dopamine agonists. Increased bioavailability w/ cimetidine & ranitidine. Increased plasma conc w/ fluoxetine & paroxetine; CYP3A4 inhibitor (eg, verapamil); phenothiazines, TCAs & some β-blockers. Decreased plasma conc w/ carbamazepine. Decreased efficacy w/ phenytoin, rifampicin & phenobarb. Decreased clearance w/ clozapine. Modestly reduced bioavailability w/ topiramate. May increase peak plasma conc of valproate.
