Interactions between your drugs

Moderate

loperamide rolapitant

Applies to: Imodium Multi-Symptom Relief (loperamide / simethicone) and rolapitant

GENERALLY AVOID: Coadministration with rolapitant may increase the plasma concentrations of drugs that are substrates of the P-glycoprotein (P-gp) efflux transporter. When a 0.5 mg dose of digoxin, a P-gp probe substrate, was administered with a 180 mg dose of rolapitant, digoxin peak plasma concentration (Cmax) and systemic exposure (AUC) increased by 70% and 30%, respectively.

MANAGEMENT: Concomitant use of rolapitant with drugs that are P-gp substrates should generally be avoided. If concomitant administration is unavoidable, caution is advised, particularly with drugs that have a narrow therapeutic range. Dosage adjustments as well as clinical and laboratory monitoring may be appropriate for some drugs whenever rolapitant is added to or withdrawn from therapy.

Drug and food interactions

Moderate

loperamide food

Applies to: Imodium Multi-Symptom Relief (loperamide / simethicone)

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.

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 interaction information available.
