Drug Interaction Report

ADJUST DOSING INTERVAL: Administration of enteric-coated, gastro-resistant formulations of peppermint oil (e.g., delayed or sustained release capsules) with food may cause premature dissolution of the enteric coating and early release of the peppermint oil, which could lead to gastrointestinal irritation and reduced therapeutic effects.

MANAGEMENT: Enteric-coated, gastro-resistant formulations of peppermint oil should not be taken immediately after eating. These products should preferably be taken 30 to 90 minutes before a meal with water. The labeling for the specific product should be consulted for administration recommendations and other guidance.

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.
