Interactions between your drugs

Moderate

tasimelteon lasmiditan

Applies to: tasimelteon and lasmiditan

MONITOR: Coadministration with alcohol or other central nervous system (CNS) depressants may enhance the sedative effects of lasmiditan and increase the likelihood and/or severity of cognitive and/or neuropsychiatric adverse reactions. Patients treated with lasmiditan are at risk of CNS depression, including dizziness and sedation, as well as driving impairment. In clinical studies, dizziness and sedation were reported in up to 17% and 7%, respectively, of patients receiving lasmiditan, and dizziness was the most common adverse event resulting in discontinuation (greater than 2%). In a computer-based driving study, a significant, dose-dependent impairment of subjects' ability to drive was observed with single 50, 100, and 200 mg lasmiditan doses at 90 minutes after administration. Concomitant use of lasmiditan and CNS depressants has not been studied clinically.

MANAGEMENT: Caution is advised during coadministration of lasmiditan with alcohol, other CNS depressants, or other agents that cause sedation. Patients should be advised against driving and other activities that require complete mental alertness for at least 8 hours after lasmiditan is administered.

Drug and food interactions

Moderate

tasimelteon food

Applies to: tasimelteon

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

ADJUST DOSING INTERVAL: Food may delay the absorption and onset of action of tasimelteon. According to the product labeling, administration of tasimelteon with a high-fat meal decreased peak plasma concentration (Cmax) by 44% and delayed the median time to reach Cmax by approximately 1.75 hours compared to administration in the fasted state.

MONITOR: Smoking induces CYP450 1A2 and may reduce the plasma concentrations of tasimelteon, which is metabolized by the isoenzyme. According to the product labeling, tasimelteon systemic exposure was approximately 40% lower in smokers than in nonsmokers.

MANAGEMENT: Patients receiving tasimelteon should be advised to avoid or limit consumption of alcohol. Tasimelteon should be taken without food. Patients who smoke may have a reduced therapeutic response to tasimelteon.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
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.
