Edit list (add/remove drugs)

Interactions between your drugs

Moderate

metyroSINE lasmiditan

Applies to: metyrosine 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.

Therapeutic duplication warnings

Therapeutic duplication is the use of more than one medicine from the same drug category or therapeutic class to treat the same condition. This can be intentional in cases where drugs with similar actions are used together for demonstrated therapeutic benefit. It can also be unintentional in cases where a patient has been treated by more than one doctor, or had prescriptions filled at more than one pharmacy, and can have potentially adverse consequences.
