Why is this medication prescribed?
Nabilone is used to treat nausea and vomiting caused by cancer chemotherapy in people who have already taken other medications to treat this type of nausea and vomiting without good results. Nabilone is in a class of medications called cannabinoids. It works by affecting the area of the brain that controls nausea and vomiting.
How should this medicine be used?
Nabilone comes as a capsule to take by mouth. It is usually taken with or without food two to three times a day during a cycle of chemotherapy. Treatment with nabilone should begin 1 to 3 hours before the first dose of chemotherapy and may be continued for up to 48 hours after the end of the chemotherapy cycle. Take nabilone at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take nabilone exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Your doctor will probably start you on a low dose of nabilone and may gradually increase your dose if needed.
Nabilone helps control nausea and vomiting caused by cancer chemotherapy when taken as directed. Always take nabilone according to the schedule prescribed by your doctor even if you are not experiencing nausea or vomiting.
Nabilone may be habit-forming. Do not take a larger dose, take it more often, or take it for a longer period of time than prescribed by your doctor. Call your doctor if you find that you want to take extra medication.

What should I know about storage and disposal of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).
Store nabilone in a safe place so that no one else can take it accidentally or on purpose. Keep track of how many capsules are left so you will know if any are missing.
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
