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 to take by mouth. When dronabinol is 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. When dronabinol is used to increase appetite, it is usually taken 2 times a day, before lunch and supper, or once a day in the evening or at bedtime. 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 split, chew, or crush them.
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.
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.
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.
