Dronabinol is used to treat nausea and vomiting caused by chemotherapy in people who have already taken other medications to treat this type of nausea and vomiting without good results. Dronabinol is also used to treat loss of appetite and weight loss in people who have acquired immunodeficiency syndrome (AIDS). Dronabinol is in a class of medications called cannabinoids. It works by affecting the area of the brain that controls nausea, vomiting, and appetite.
Dronabinol comes as a capsule and as a solution (liquid) to take by mouth. When dronabinol capsules and solution are used to treat nausea and vomiting caused by chemotherapy, it is usually taken 1 to 3 hours before chemotherapy and then every 2 to 4 hours after chemotherapy, for a total of 4 to 6 doses a day. The first dose of the solution is usually taken on an empty stomach at least 30 minutes before eating, but the following doses can be taken with or without food. When dronabinol capsules and solution are used to increase appetite, they are usually taken twice a day, about an hour before lunch and supper Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take dronabinol exactly as directed.
Swallow the capsules whole; do not chew or crush them.
Swallow the dronabinol solution with a full glass of water (6 to 8 ounces).
Always use the oral dosing syringe that comes with dronabinol solution to measure your dose. Talk to your doctor or pharmacist if you have questions about how to measure your dose of dronabinol solution.
Your doctor will probably start you on a low dose of dronabinol and may gradually increase your dose. Your doctor may also decrease your dose if you experience side effects that do not go away after 1 to 3 days. Be sure to tell your doctor how you are feeling during your treatment with dronabinol.
Dronabinol 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.
Dronabinol will control your symptoms only as long as you take the medication. Continue to take dronabinol even if you feel well. Do not stop taking dronabinol without talking to your doctor. If you suddenly stop taking dronabinol, you may experience withdrawal symptoms such as irritability, difficulty falling asleep or staying asleep, restlessness, hot flashes, sweating, runny nose, diarrhea, hiccups, and loss of appetite.
Ask your doctor or pharmacist for a copy of the manufacturer's information for the patient.
Before taking dronabinol,
Talk to your doctor or nutritionist and read the manufacturer's information for the patient to find out about ways to encourage yourself to eat when your appetite is poor and about which types of foods are the best choices for you.
Do not eat grapefruit or drink grapefruit juice while taking dronabinol oral solution.
Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
Dronabinol may cause side effects. Tell your doctor if any of these symptoms are severe or do not go away:
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store capsules in a cool place (between 46-59 °F, 8-15 °C) or in the refrigerator. Do not allow the capsules to freeze. Store the unopened dronabinol solution in the container in the refrigerator. Once opened, the dronabinol solution can be stored at room temperature for up to 28 days. Keep medication away from heat, direct light, and moisture.
Store dronabinol in a safe place so that no one else can take it accidentally or on purpose. Keep track of how many capsules and solution are remaining so you will know if any medication is missing.
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. Web Site
