Dosage
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.
Side Effects
6 ADVERSE REACTIONS Most common adverse reactions (≥3%) are: abdominal pain, dizziness, euphoria, nausea, paranoid reaction, somnolence, thinking abnormal, and vomiting. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Wellhouse Pharma, LLC at 1-844-558-8289 or FDA at MedWatch phone number 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The following serious adverse reactions are described below and elsewhere in the labeling.
Interactions
7 DRUG INTERACTIONS Inhibitors and Inducers of CYP2C9 and CYP3A4 : May alter dronabinol systemic exposure; monitor for dronabinol-related adverse reactions or loss of efficacy. ( 7.2 ) Highly Protein-Bound Drugs : Potential for displacement of other drugs from plasma proteins; monitor for adverse reactions to concomitant narrow therapeutic index drugs (e.g., warfarin, cyclosporine, or amphotericin B) when initiating or increasing the dosage of dronabinol oral solution. ( 7.3 ) 7.1 Disulfiram and Metronidazole Dronabinol oral solution contains 50% (w/w) dehydrated alcohol and 5.5% (w/w) propylene glycol, which can produce disulfiram-like reactions when co-administered with disulfiram or other drugs that produce this reaction (e.g., metronidazole).
Warnings
5 WARNINGS AND PRECAUTIONS Neuropsychiatric Adverse Reactions : May cause psychiatric and cognitive effects and impair mental and/or physical abilities. Avoid use in patients with a psychiatric history. Monitor for symptoms and avoid concomitant use of drugs with similar effects. Inform patients not to operate motor vehicles or other dangerous machinery until they are reasonably certain that dronabinol oral solution does not affect them adversely. ( 5.1 ) Hemodynamic Instability : Patients with cardiac disorders may experience hypotension, hypertension, syncope, or tachycardia. Avoid concomitant use of drugs with similar effects and monitor for hemodynamic changes after initiating or increasing the dosage of dronabinol oral solution. 4 CONTRAINDICATIONS Dronabinol oral solution is contraindicated in patients: with a history of a hypersensitivity reaction to dronabinol. Reported hypersensitivity reactions to dronabinol include lip swelling, hives, disseminated rash, oral lesions, skin burning, flushing, throat tightness [see Adverse Reactions ( 6.2 )] . with a history of a hypersensitivity reaction to alcohol.
Pregnancy
8.1 Pregnancy Risk Summary Dronabinol oral solution, a synthetic cannabinoid containing alcohol, may cause fetal harm. Avoid use of dronabinol oral solution in pregnant women. Although there is little published data on the use of synthetic cannabinoids during pregnancy, use of cannabis (e.g., marijuana) and use of alcohol during pregnancy have been associated with adverse fetal/neonatal outcomes (see Clinical Considerations ) . Cannabinoids have been found in the umbilical cord blood from pregnant women who smoke cannabis.
