Drug Interaction Report

GENERALLY AVOID: Coadministration with lasmiditan may increase the plasma concentrations of drugs that are substrates of the P-glycoprotein (P-gp) and/or breast cancer resistance protein (BCRP) transporters. The proposed mechanism, based on in vitro data, involves decreased clearance due to inhibition of P-gp and BCRP by lasmiditan. The clinical relevance is unknown.

MANAGEMENT: Concomitant use of lasmiditan with drugs that are P-gp and/or BCRP substrates should be avoided when possible. If coadministration is required, patients should be carefully monitored for increased adverse reactions of these drugs and dosing adjusted as necessary.

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.
