Generic name: DRONABINOL 5mg in 1mL
Dosage form: oral solution
Medically reviewed on September 1, 2017.
Important Administration Instructions
- Always use the enclosed calibrated oral dosing syringe when administering SYNDROS to ensure the dose is measured and administered accurately.
- The calibrated oral syringe measures a maximum SYNDROS 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 SYNDROS with a full glass of water (6 to 8 ounces).
- For information on dosing SYNDROS with regard to meals, see Dosage and Administration 2.2 and 2.3.
Anorexia Associated with Weight Loss in Adult Patients with AIDS
The recommended adult starting dosage of SYNDROS 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 SYNDROS 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.
- 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 SYNDROS 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.
Nausea and Vomiting Associated with Cancer Chemotherapy in Adult Patients Who Failed Conventional Antiemetics
The recommended starting dosage of SYNDROS is 4.2 mg/m2 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 m2 multiplied by 4.2 mg/m2
- Round dose to the nearest 0.1 mg increment
- 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 SYNDROS at 2.1 mg/m2 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 SYNDROS, 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.
- 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/m2.
- Maximum Dosage: 12.6 mg/m2 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.
