bortezomib injection 1 MG and 2.5 MG VIAL Drug Interactions (bortezomib for injection)

7 DRUG INTERACTIONS

7.1 Effects of Other Drugs on Bortezomib

Strong CYP3A4 Inducers

Coadministration with a strong CYP3A4 inducer decreases the exposure of bortezomib [see Clinical Pharmacology (12.3)] which may decrease Bortezomib for Injection efficacy. Avoid coadministration with strong CYP3A4 inducers.

Strong CYP3A4 Inhibitors

Coadministration with a strong CYP3A4 inhibitor increases the exposure of bortezomib [see Clinical Pharmacology (12.3)] which may increase the risk of Bortezomib for Injection toxicities. Monitor patients for signs of bortezomib toxicity and consider a bortezomib dose reduction if bortezomib must be given in combination with strong CYP3A4 inhibitors.

7.2 Drugs Without Clinically Significant Interactions with Bortezomib

No clinically significant drug interactions have been observed when Bortezomib for Injection was coadministered with dexamethasone, omeprazole, or melphalan in combination with prednisone [see Clinical Pharmacology (12.3)].
