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.

What other drugs will affect Marinol

Sometimes it is not safe to use certain medications at the same time. Some drugs can affect your blood levels of other drugs you take, which may increase side effects or make the medications less effective.

Using Marinol with other drugs that make you drowsy can worsen this effect. Ask your doctor before using opioid medication, a sleeping pill, a muscle relaxer, or medicine for anxiety or seizures.

Other drugs may interact with dronabinol, including prescription and over-the-counter medicines, vitamins, and herbal products. Tell your doctor about all your current medicines and any medicine you start or stop using.
