Marinol Dosage

Anorexia Associated with Weight Loss in Adult Patients with AIDS

Starting Dosage
The recommended adult starting dosage of MARINOL is 2.5 mg orally twice daily, one hour before lunch and dinner.
In elderly patients or patients unable to tolerate 2.5 mg twice daily, consider initiating MARINOL at 2.5 mg once daily one hour before dinner or at bedtime to reduce the risk of central nervous system (CNS) symptoms.
Dosing later in the day may reduce the frequency of CNS adverse reactions. CNS adverse reactions are dose-related; 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 2.5 mg in the evening or at bedtime.
Dosage Titration
If tolerated and further therapeutic effect is desired, the dosage may be increased gradually to 2.5 mg one hour before lunch and 5 mg one hour before dinner. Increase the dose of MARINOL gradually in order to reduce the frequency of dose-related adverse reactions.
Most patients respond to 2.5 mg twice daily, but the dose may be further increased to 5 mg one hour before lunch and 5 mg one hour before dinner, as tolerated to achieve a therapeutic effect.
Maximum Dosage: 10 mg twice daily.

Nausea and Vomiting Associated with Cancer Chemotherapy in Adult Patients Who Failed Conventional Antiemetics

Starting Dosage

The recommended starting dosage of MARINOL is 5 mg/m2, orally administered 1 to 3 hours prior to the administration of chemotherapy and then every 2 to 4 hours after chemotherapy, for a total of 4 to 6 doses per day.

In elderly patients, consider initiating MARINOL at 2.5 mg/m2 once daily 1 to 3 hours prior to chemotherapy to reduce the risk of CNS symptoms.

Administer the first dose on an empty stomach at least 30 minutes before eating. Subsequent doses can be taken without regard to meals.

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 response, as tolerated to achieve a clinical effect, in increments of 2.5 mg/m2.

The maximum dosage is 15 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. Monitor patients for adverse reactions and consider decreasing the dose to 2.5 mg once daily 1 to 3 hours prior to chemotherapy to reduce the risk of CNS adverse reactions.
