Fedratinib Disease Interactions

There are 3 disease interactions with fedratinib:


Fedratinib (applies to fedratinib) severe hepatic impairment

Major Potential Hazard, Moderate plausibility. Applicable conditions: Liver Disease

The pharmacokinetics of fedratinib have not been evaluated in patients with severe hepatic impairment (total bilirubin > 3 times ULN and any AST), and its use should be avoided on these patients.


Fedratinib (applies to fedratinib) thiamine deficiency

Major Potential Hazard, Moderate plausibility.

Serious and fatal encephalopathy, including Wernicke's disease, has occurred in patients treated with fedratinib. Wernicke's encephalopathy is a neurologic emergency. Assess thiamine levels in all patients prior to starting treatment, periodically during treatment, and as clinically indicated. Do not start fedratinib in patients with thiamine deficiency; replete thiamine prior to treatment initiation. If encephalopathy is suspected, immediately discontinue fedratinib and initiate parenteral thiamine. Monitor until symptoms resolve or improve and thiamine levels normalize.


Fedratinib (applies to fedratinib) renal impairment

Moderate Potential Hazard, Moderate plausibility. Applicable conditions: Renal Dysfunction

Due to potential increase of exposure, patients with preexisting-existing moderate renal impairment require more intensive safety monitoring, and if necessary, dose modifications based on adverse reactions when treated with fedratinib. Reduce fedratinib dose when administered to patients with severe renal impairment (CrCl 15 mL/min to 29 mL/min by Cockcroft-Gault). No modification of the starting dose is recommended for patients with mild to moderate renal impairment (CrCl 30 mL/min to 89 mL/min by Cockcroft-Gault).

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
