CYP3A4 inducers: Avoid concomitant use with CAPLYTA.
Table 6: Clinically Important Drug Interactions with CAPLYTA CYP3A4 Inducers* Prevention or Management Avoid concomitant use of CAPLYTA with CYP3A4 inducers .
Clinical Impact Concomitant use of CAPLYTA with CYP3A4 inducers decreases the exposure of lumateperone [see Clinical Pharmacology ( 12.3 ) ].
…interactions with adjunctive SSRI/SNRIs in MDD were observed in CAPLYTA clinical trials, CAPLYTA’s moderate serotonin transporter (SERT) activity may increase the risk of SRI-associated adverse reactions (e.g., serotonin syndrome, hyponatremia). * See www.fda.gov/CYPandTransporterInteractingDrugs for examples of CYP3A4 Inducers and Moderate or Strong CYP3A4 Inhibitors
