Monitor for cytopenias; obtain CBCs during therapy; interrupt, reduce dose, or discontinue as warranted. Monitor for cardiac arrhythmias (esp. in those with cardiac risk factors, hypertension, previous arrhythmias); manage appropriately. Second primary malignancies (eg, non-melanoma skin cancer, solid tumors, melanoma, others); advise to use sun protection; monitor.

Following a single radiolabeled dose of pirtobrutinib 200mg to healthy subjects, 37% of the dose was recovered in feces (18% unchanged) and 57% in urine (10% unchanged). The effective half-life of pirtobrutinib is ~19 hours.
Concomitant strong CYP3A inhibitors may increase risk of pirtobrutinib toxicities (eg, itraconazole); avoid use. If concomitant strong CYP3A inhibitors is unavoidable, reduce pirtobrutinib dose (see Adults). Concomitant moderate or strong CYP3A inducers may reduce pirtobrutinib efficacy (eg, efavirenz, bosentan, rifampin); avoid use. If concomitant moderate CYP3A inducers is unavoidable, increase pirtobrutinib dose (see Adults). Concomitant sensitive P-gp, CYP2C8, BCRP, CYP2C19, or CYP3A substrates may increase risk of adverse reactions related to substrates (eg, digoxin, repaglinide, rosuvastatin, omeprazole, midazolam). Caution with antithrombotic agents; monitor for bleeding.
