Interaction Coadministration of cabozantinib and drugs that interfere with platelet function or coagulation may potentiate the risk of bleeding complications. Treatment with cabozantinib is associated with severe, sometimes fatal hemorrhage including hemoptysis and gastrointestinal hemorrhage.
Management Concomitant use of other medications that interfere with platelet function or coagulation should be considered cautiously in patients treated with cabozantinib. Close clinical and laboratory observation for bleeding complications is recommended during therapy. The INR should be monitored more frequently during coadministration of warfarin. Patients should be advised to promptly report any signs of bleeding to their physician, including pain, swelling, headache, dizziness, weakness, prolonged bleeding from cuts, increased menstrual flow, vaginal bleeding, nosebleeds, bleeding of gums from brushing, unusual bleeding or bruising, red or brown urine, or red or black stools.

Potential Metabolism Interactions
Substrate-Substrate Interaction：If more than one drug is metabolized by the same CYP, it is possible that its metabolism is inhibited because of the competition between the drugs. That means, it can be useful to lower the dosage of the drugs in the drug-cocktail because they remain longer in the organism than in monotherapy.
Inhibitor-Inhibitor Interaction：Combining two or more inhibitors of one CYP, should be compensated by lowering the dosage of these drugs because the metabolism is reduced and the drugs remain longer in the organism than in monotherapy. Not adapting the dosage bears the risk of even more side effects.
Inhibitor-Substrate Interaction：Combining drugs that have inhibitory effect and are substrates of one particular CYP, should be compensated by lowering the dosage. They rest longer in the organism than in monotherapy. Not adapting the dosage bears the risk of even more side effects.
