divalproex sodium ↔ paliperidone

Applies to:Depakote (divalproex sodium) and Invega Sustenna (paliperidone)

Consumer information for this interaction is not currently available.

MONITOR: Coadministration with valproic acid may increase the plasma concentrations of orally administered paliperidone. The mechanism of interaction has not been established, but may involve increased gastrointestinal absorption of paliperidone. When a single 12 mg oral dose of extended-release (ER) paliperidone was coadministered with divalproex sodium ER at 1000 mg orally once daily, paliperidone peak plasma concentration (Cmax) and systemic exposure (AUC) increased by approximately 50%. No effect on the systemic clearance was observed; therefore, a clinically significant interaction would not be expected when paliperidone is administered by intramuscular injection. Conversely, coadministration of paliperidone ER (12 mg orally once daily for 5 days) with divalproex sodium ER (500 to 2000 mg orally once daily) did not affect the steady-state pharmacokinetics of valproate in 13 patients stabilized on valproate therapy. In a clinical study, subjects on stable doses of valproate had comparable valproate average plasma concentrations when oral paliperidone ER 3 to 15 mg/day was added to their existing valproate treatment.

MONITOR: Concomitant use of paliperidone and valproic acid may increase central nervous system depressant effects such as somnolence and impairment of cognitive and psychomotor skills.

MANAGEMENT: Caution is advised during concomitant use of oral paliperidone and valproate products. Pharmacologic response to paliperidone should be monitored more closely following the initiation or withdrawal of valproate therapy, and the paliperidone dosage adjusted as necessary. No dosage adjustment for paliperidone is required when it is administered by intramuscular injection. Additionally, no dosage adjustment is necessary for valproate when coadministered with paliperidone. Patients should be advised to avoid hazardous activities requiring mental alertness and motor coordination until they know how these agents affect them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities.

Drug Interaction Classification

The classifications below are a guideline only. The relevance of a particular drug interaction to a specific patient is difficult to determine using this tool alone given the large number of variables that may apply.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No information available.
