IMPORTANT SAFETY INFORMATION
What is the most important information I should know about TURALIO™ (pexidartinib)?
TURALIO can cause serious side effects, including serious liver problems, which may be severe and can lead to death.
Your healthcare provider will do blood tests to check for liver problems:
- before starting treatment with TURALIO
- every week for the first 8 weeks during treatment
- every 2 weeks for the next month
- then every 3 months after that
If you develop liver problems during treatment with TURALIO, your healthcare provider may do blood tests more often to monitor you. It is important to stay under the care of your healthcare provider during treatment with TURALIO.
Stop taking TURALIO and call your healthcare provider right away if you develop yellowing of your skin and whites of your eyes or dark urine.
Tell your healthcare provider right away if you have any of these symptoms of liver problems while taking TURALIO: lack or loss of appetite, right upper stomach-area (abdomen) pain or tenderness, feeling overly tired, nausea, vomiting, fever, rash, or itching.
TURALIO Risk Evaluation and Mitigation Strategy (REMS): Because of the risk of serious liver problems, TURALIO is available only through a restricted program called the TURALIO REMS Program. Your healthcare provider must be enrolled in the program in order for you to be prescribed TURALIO. There is a registry that collects information about the effects of taking TURALIO over time. You must complete and sign an enrollment form for the TURALIO REMS Program and the registry. Ask your healthcare provider for more information.
