Information from PubChem

"Bortezomib mainly causes sensory peripheral neuropathy, but severe motor peripheral neuropathy also has been reported. In the phase III trial, peripheral neuropathy occurred in thirty-six percent (36%) of patients receiving bortezomib and nine percent (9%) of patients receiving dexamethasone. About 8% of patients discontinued bortezomib therapy because of peripheral neuropathy."

"Patients receiving bortezomib should be monitored for manifestations of neuropathy (eg, burning sensation, hyperesthesia, hypoesthesia, paresthesia, discomfort, neuropathic pain). Dose and/or frequency of administration of bortezomib should be adjusted in patients who experience new-onset or exacerbation of peripheral neuropathy."

"Hypoglycemia and hyperglycemia have been reported in patients with diabetes mellitus who received bortezomib concomitantly with oral antidiabetic agents. If bortezomib is used concomitantly with oral antidiabetic agents, blood glucose concentrations should be monitored carefully and dosage of the antidiabetic agent adjusted as necessary."

"Potential interaction (increased risk of hypotension) when bortezomib is used with drugs that can cause hypotension. Dosage adjustment of hypotensive agents may be necessary."
