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, including liver failure and a liver injury called vanishing bile duct syndrome (VBDS) that can cause the loss of bile ducts in the liver. Severe or life-threatening liver problems can happen with TURALIO even if your healthcare provider monitors liver blood tests during treatment and stops treatment with TURALIO. 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.
Before you take TURALIO, tell your healthcare provider about all of your medical conditions, including if you have or had liver or kidney problems, are pregnant or plan to become pregnant, or are breastfeeding or plan to breastfeed. TURALIO may harm your baby. Do not breastfeed during treatment with TURALIO and for at least 1 week after your final dose.
Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Certain medicines may affect the way TURALIO works and TURALIO may affect how other medicines work. Taking TURALIO with certain medicines may increase the amount of TURALIO in your blood. This may make it more likely for you to have side effects and may cause more severe side effects. Avoid taking proton pump inhibitor medicines and St. John’s wort because they can affect how TURALIO works. If you take an antacid medicine, take TURALIO either 2 hours before or 2 hours after taking an antacid medicine. If you take an H2 receptor blocker medicine, take TURALIO at least 2 hours before or 10 hours after taking an H2 receptor blocker medicine.
Take TURALIO with a low-fat meal (about 11 to 14 grams of total fat). See “What should I avoid while taking TURALIO?” TURALIO capsules must be swallowed whole. Do not open, break, or chew TURALIO capsules.
