Concurrent use of PEMAZYRE with strong CYP3A4 inhibitors (eg, itraconazole, ketoconazole, ritonavir) should be avoided. Concomitant use of PEMAZYRE with strong (eg, carbamazepine, phenytoin, phenobarbital, rifampicin) or moderate CYP3A4 inducers is not recommended. Concomitant use of PEMAZYRE with St John’s wort is contraindicated. If needed, other enzyme inducers (eg, efavirenz) should be used under close surveillance. Concomitant use of PEMAZYRE with proton pump inhibitors should be avoided.1

Co-administration of PEMAZYRE with CYP2B6 substrates (eg, cyclophosphamide, ifosfamide, methadone, efavirenz) may decrease their exposure. Close clinical surveillance is recommended when PEMAZYRE is administered with these medicinal products. Co-administration of PEMAZYRE with P-gp substrates (eg, digoxin, dabigatran, colchicine) may increase their exposure and thus their toxicity. PEMAZYRE administration should be separated by at least 6 hours before or after administration of P-gp substrates with a narrow therapeutic index.1

Patients should be advised to avoid eating grapefruit or drinking grapefruit juice while taking PEMAZYRE. In all patients, a low-phosphate diet should be initiated when serum phosphate level is >5.5 mg/dL and adding a phosphate-lowering therapy should be considered when level is >7 mg/dL.1
PEMAZYRE has a moderate influence on the ability to drive and use machines. Adverse reactions such as fatigue and visual disturbances have been associated with PEMAZYRE. Therefore, caution should be recommended when driving or operating machines.1
Fibroblast growth factor receptor 2 (FGFR2) fusion positivity status must be known prior to initiation of PEMAZYRE therapy. Assessment for FGFR2 fusion positivity in tumour specimens should be performed with an appropriate diagnostic test. A pregnancy test should be performed before treatment initiation to exclude pregnancy.1
