Typical dosage for Vitrakvi

Your oncologist will determine your dose based on your body surface area (BSA), which takes your height and weight into account. The dose is the same for the capsules and oral solution.

  • BSA of 1 m2 or higher: The recommended dose is 100 mg by mouth twice a day.
  • BSA less than 1 m2: The dose is calculated from your BSA. The recommended dose is 100 mg/m2 of BSA by mouth twice a day.

Your oncologist might adjust your dose if you take medications that interact with Vitrakvi (larotrectinib). People with liver problems or side effects during treatment might take a lower dose.
