Your dose may vary, but the usual dose of idelalisib is 150 milligrams 150 mg to be taken by mouth at a scheduled time twice a day. Idelalisib can be taken with or without food, but at the same time each day. Idelalisib should be taken whole and not crushed, cut, or dissolved. If you are unable to swallow idelalisib, talk to your care provider or pharmacist for possible options. If you miss a dose of idelalisib, follow these guidelines: Only take the missed dose if it has been less than six hours since you were supposed to take it. Then take the next dose at the regularly scheduled time. Do not take the missed dose if it has been more than six hours since you should have taken it. Simply take the next dose at the regularly scheduled 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. Storage and handling Handle idelalisib 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 idelalisib at room temperature 68°F–77°F in a dry location away from light. Keep idelalisib out of reach of children and pets. Leave idelalisib in the provided packaging until it is ready to be taken. Whenever possible, you should give idelalisib to yourself and follow the steps below. If a family member, friend, or caregiver needs to give the idelalisib 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. IDELALISIB ORAL CHEMOTHERAPY EDUCATION Page 2 3. Gently transfer the idelalisib from its package to a small medicine or other disposable cup. 4. Administer the medicine immediately by mouth with water. 5. Remove gloves and do not use them for anything else. 6. Throw gloves and medicine cup in household trash. 7. Wash hands with soap and water. If a daily pill box or pill reminder is used, a separate one should be used for idelalisib. Do not mix other medications into the box with idelalisib. The person filling the box or reminder should wear gloves. Gloves are not necessary if you are filling the box or reminder. 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 idelalisib, 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 idelalisib. If you are traveling, put your idelalisib in a sealed plastic bag. Ask your pharmacist if any additional travel precautions are needed. Handling body fluids and waste Since idelalisib remains in your body for several days after it is taken, some of the drug may be present in urine, stool, sweat, or vomit. Once you have started to take idelalisib, it is important to know the following instructions every day for as long as your treatment lasts. This is to keep yourself, loved ones, and the environment as safe as possible. Pregnant women should avoid touching anything that may be soiled with body fluids from the patient. Toilet and septic systems You may use the same toilet, septic tank, and/or sewer that you usually use. If you have a low flow toilet, close the lid and flush twice to ensure that all waste has been discarded. If the toilet or toilet seat becomes soiled with urine, stool, or vomit, clean the surfaces before other people use the toilet. Wash hands with soap and water after using the toilet. If you need a bedpan, be sure your caregiver knows to wear gloves to assist with cleanup and to wash the bedpan with soap and water every day. If you do not have good control of bladder or bowels, use a disposable pad with a plastic back, a diaper, or a sheet to absorb body waste. Wash any skin that has been exposed to body waste or idelalisib with soap and water. Linens or clothing that are soiled with body fluids or body waste should be washed separately from other linens and clothing. If you do not have a washer, place the soiled linens in a plastic bag until they can be washed. Wash hands with soap and water after touching linens or clothing that may be soiled with body fluids. Drug and food interactions Idelalisib has many drug interactions. Inform your care providers of all prescription medications, over the counter medications, vitamins, and herbal products. Talk with your care provider or pharmacist before taking new medications or supplements, or receiving any vaccines. Avoid live vaccines during treatment with idelalisib.
