Dasatinib is used for:

Do NOT use dasatinib if:

  • you are allergic to any ingredient in dasatinib
  • you are taking an H2 blocker (eg, famotidine), a proton pump inhibitor (eg, omeprazole), or St. John's wort

Contact your doctor or health care provider right away if any of these apply to you.
