Dose and schedule Taking avapritinib as instructed is important to allow your treatment to be as effective as possible, so here are some key points to remember. Your dose may vary, but the usual dose of avapritinib is 300 milligrams (300 mg) to be taken by mouth at a scheduled time once a day. Avapritinib should be taken on an empty stomach, at least one hour before and two hours after a meal. Avapritinib should be taken whole and not crushed, cut, or dissolved. If you are unable to swallow avapritinib, talk to your care provider or pharmacist for possible options. If you miss a dose of avapritinib, follow these guidelines: Take it as soon as you remember, unless your next scheduled dose is due within eight hours. Take the next dose at your regular time. Do not take two doses at one time. Be sure to write down if you miss a dose, and let your care provider know about any missed doses. Drug and food interactions Avapritinib has many drug interactions. Please inform your care providers of all prescription medications, over the counter medications, vitamins, and herbal products. Avapritinib should not be taken with food. Talk with your care provider or pharmacist before taking new medications or supplements, or receiving any vaccines. Storage and handling Handle avapritinib with care. Just like when chemotherapy is given into the vein, this drug can be toxic, and exposure of the drug to others should be limited. Store avapritinib at room temperature (68°F–77°F) in a dry location away from light. Keep avapritinib out of reach of children and pets. Leave avapritinib in the provided packaging until it is ready to be taken.

If a family member, friend, or caregiver needs to give the avapritinib to you, they also need to follow these steps. 1. Wash hands with soap and water. 2. Put on gloves to avoid touching the medication. (Gloves are not necessary if you give the drug to yourself.) 3. Gently transfer the avapritinib from its package to a small medicine or other disposable cup. 4. Administer the medicine immediately by mouth with water. 5.

When empty, the box or reminder should be washed with soap and water before refilling. Be sure to wash hands with soap and water after the task is complete, whether or not gloves are worn. If you have any unused avapritinib, do not throw it in the trash and do not flush it down the sink or toilet. Talk to your care provider or pharmacist about proper disposal of avapritinib.
