Dronabinol

2 DOSAGE AND ADMINISTRATION Administration ( 2.1 ): Always use the enclosed calibrated oral dosing syringe. The calibrated oral syringe measures a maximum dronabinol oral solution dose of 5 mg. If the prescribed dose is greater than 5 mg, the total dose will need to be divided and drawn up in two or more portions using the oral syringe. Take dronabinol oral solution with a full glass of water (6 to 8 ounces). Dronabinol oral solution can be administered via silicone enteral feeding tubes. Anorexia Associated with Weight Loss in Adult Patients with AIDS ( 2.2 ): The recommended starting dosage is 2.1 mg orally twice daily, one hour before lunch and dinner. See the full prescribing information for dosage titration to manage adverse reactions and to achieve desired therapeutic effect. Nausea and Vomiting Associated with Chemotherapy in Adult Patients Who Failed Conventional Antiemetics ( 2.3 ): The recommended starting dosage is 4.2 mg/m 2 , administered 1 to 3 hours prior to chemotherapy, then every 2 to 4 hours after chemotherapy for a total of 4 to 6 doses per day. Administer the first dose on an empty stomach at least 30 minutes prior to eating; subsequent doses can be taken without regard to meals. See the full prescribing information for dosage titration to manage adverse reactions and to achieve desired therapeutic effect. 2.1 Important Administration Instructions Oral Administration Always use the enclosed calibrated oral dosing syringe when administering dronabinol oral solution to ensure the dose is measured and administered accurately. The calibrated oral syringe measures a maximum dronabinol oral solution dose of 5 mg. If the prescribed dose is greater than 5 mg, the total dose will need to be divided and drawn up in two or more portions using the oral syringe. Take each dose of dronabinol oral solution with a full glass of water (6 to 8 ounces). For information on dosing dronabinol oral solution with regard to meals, see Dosage and Administration 2.2 and 2.3 . Administration via Feeding Tube (silicone only, greater than or equal to 14 French) Dronabinol oral solution can be administered via enteral feeding tubes that are manufactured using silicone, size greater than or equal to 14 French, such as Naso-Gastric (NG), Gastrostomy Tube (G-tube), Percutaneous Endoscopic Gastrostomy tube (PEG-tube) and Gastro-Jejunostomy tube (GJ-tube). Do not use tubes manufactured of polyurethane. Draw up the prescribed dose with the calibrated dosing syringe packaged with dronabinol oral solution. If the prescribed dose is greater than 5 mg, the total dose will need to be divided and drawn up in two or more portions using the oral syringe. Using the calibrated dosing syringe, administer the dose via the feeding tube. Using a catheter-tip syringe, flush the feeding tube with 30 mL of water. 2.2 Anorexia Associated with Weight Loss in Adult Patients with AIDS Starting Dosage The recommended adult starting dosage of dronabinol oral solution is 2.1 mg orally twice daily, one hour before lunch and one hour before dinner. In elderly patients, or patients unable to tolerate 2.1 mg twice daily, consider initiating dronabinol oral solution at 2.1 mg once daily one hour before dinner or at bedtime to reduce the risk of central nervous system (CNS) symptoms [see Use in Specific Populations (8.5) ]. Dosing later in the day may reduce the frequency of Central Nervous System (CNS) adverse reactions. CNS adverse reactions are dose-related [see Warnings and Precautions (5.1) ] ; therefore, monitor patients and reduce the dosage as needed. If CNS adverse reactions of feeling high, dizziness, confusion, and somnolence occur, they usually resolve in 1 to 3 days and usually do not require dosage reduction. If CNS adverse reactions are severe or persistent, reduce the dosage to 2.1 mg once daily one hour before dinner or in the evening at bedtime. Dosage Titration If tolerated and further therapeutic effect is desired, the dosage may be increased gradually to 2.1 mg one hour before lunch and 4.2 mg one hour before dinner. Increase the dose of dronabinol oral solution gradually in order to reduce the frequency of dose-related adverse reactions [see Warnings and Precautions (5.1) ]. Most patients respond to 2.1 mg twice daily, but the dose may be further increased to 4.2 mg one hour before lunch and 4.2 mg one hour before dinner, as tolerated to achieve a therapeutic effect. Maximum Dosage: 8.4 mg twice daily. 2.3 Nausea and Vomiting Associated with Cancer Chemotherapy in Adult Patients Who Failed Conventional Antiemetics Starting Dosage The recommended starting dosage of dronabinol oral solution is 4.2 mg/m 2 orally administered 1 to 3 hours prior to chemotherapy and then every 2 to 4 hours after chemotherapy for a total of 4 to 6 doses per day. Calculate the starting dose by following the steps below: Starting dose (mg) = Patient body surface area (BSA) in m 2 multiplied by 4.2 mg/m 2 Round dose to the nearest 0.1 mg increment Convert from milligrams (mg) to milliliters (mL): Starting dose (mg) rounded to the nearest 0.1 mg increment divided by 5 = Starting dose in milliliters (mL) To correspond with the calibrated oral dosing syringe, the dose may need to be rounded to the nearest 0.1 mL increment. In elderly patients, consider initiating dronabinol oral solution at 2.1 mg/m 2 once daily 1 to 3 hours prior to chemotherapy to reduce the risk of CNS symptoms [see Use in Specific Populations (8.5) ] . Because food delays the absorption of dronabinol oral solution, administer the first dose on an empty stomach at least 30 minutes before eating. Subsequent doses can be taken without regard to meals. Because food can substantially change the systemic exposure to dronabinol and its active metabolite, the timing of dosing in relation to meal times should be kept consistent for each chemotherapy cycle, once the dosage has been determined from the titration process. Dosage Titration The dosage can be titrated to clinical response during a chemotherapy cycle or subsequent cycles, based upon initial effect, as tolerated to achieve a clinical effect, in increments of 2.1 mg/m 2 . Maximum Dosage: 12.6 mg/m 2 per dose for 4 to 6 doses per day. Adverse reactions are dose-related and psychiatric symptoms increase significantly at the maximum dosage [see Warnings and Precautions (5.1) ] . Monitor patients for adverse reactions and consider decreasing the dose to 2.1 mg once daily 1 to 3 hours prior to chemotherapy to reduce the risk of CNS adverse reactions.
