What is Marinol?

Marinol (dronabinol) is a man-made form of cannabis (also known as marijuana).

Marinol is used to treat loss of appetite that causes weight loss in people with AIDS. It is also used to treat severe nausea and vomiting caused by cancer chemotherapy. Marinol is for use only when other medications have been unable to control the nausea and vomiting.

Important information

Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.

Marinol may be habit-forming and should be used only by the person it was prescribed for. It should never be given to another person, especially someone who has a history of drug addiction or habitual marijuana use. Keep the medication in a secure place where others cannot get to it.

Avoid using other medicines that affect the central nervous system (such as stimulants, diet pills, cold medicine, pain medication, muscle relaxers, and medicine for seizures, depression, anxiety, mental illness, or Parkinson's disease). These other drugs can add to the effects of Marinol.

Marinol causes effects that will impair your thinking or reactions. Do not drive or do anything that requires you to be awake and alert until the effects wear off.
