Drug Interactions between ibuprofen and Invega Sustenna

GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of paliperidone. Use in combination may result in additive central nervous system depression and/or impairment of judgment, thinking, and psychomotor skills.

Administration with food may increase the bioavailability of paliperidone from the extended release tablets. In healthy ambulatory subjects, administration of a 12 mg paliperidone extended release tablet with a standard high-fat/high-caloric meal resulted in 60% and 54% increases, respectively, in the mean peak plasma concentration (Cmax) and area under the concentration-time curve (AUC) of paliperidone compared to administration under fasting conditions. The clinical significance of these changes is unknown.

MANAGEMENT: Patients receiving paliperidone should be advised to avoid the consumption of alcohol. Since clinical trials establishing the safety and efficacy of paliperidone were carried out without regard to the timing of meals, presumably paliperidone may be administered with or without food.

GENERALLY AVOID: The concurrent use of aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs) and ethanol may lead to gastrointestinal (GI) blood loss. The mechanism may be due to a combined local effect as well as inhibition of prostaglandins leading to decreased integrity of the GI lining.

MANAGEMENT: Patients should be counseled on this potential interaction and advised to refrain from alcohol consumption while taking aspirin or NSAIDs.
