Drug Interaction Report

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

MANAGEMENT: Patients receiving CNS-active agents should be warned of this interaction and advised to avoid or limit consumption of alcohol. Ambulatory patients should be counseled to avoid hazardous activities requiring complete 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.

GENERALLY AVOID: Lanthanum carbonate should be administered with food for therapeutic efficacy. However, it is insoluble in water (<0.01 mg/mL at pH 7.5) and therefore cannot be dissolved in liquid for administration through an enteral feeding tube, because it may result in blockage of the tube.

MANAGEMENT: Administration of lanthanum carbonate with enteral feedings is not recommended. Alternative medications such as calcium carbonate suspension should be considered.
