What is SYNDROS?

  • SYNDROS is a prescription medicine used in adults to treat:
    • nausea and vomiting caused by anti-cancer medicine (chemotherapy) in adults whose nausea and vomiting have not improved with usual anti-nausea medicines.
    • loss of appetite (anorexia) in adults with AIDS (Acquired Immune Deficiency Syndrome) who have lost weight.
SYNDROS IS A CONTROLLED SUBSTANCE (CII) BECAUSE IT CONTAINS DRONABINOL WHICH CAN BE A TARGET FOR PEOPLE WHO ABUSE PRESCRIPTION MEDICINES OR STREET DRUGS. KEEP YOUR SYNDROS IN A SAFE PLACE TO PROTECT IT FROM THEFT. NEVER GIVE YOUR SYNDROS TO ANYONE ELSE BECAUSE IT MAY CAUSE DEATH OR HARM THEM. SELLING OR GIVING AWAY THIS MEDICINE IS AGAINST THE LAW.
IT IS NOT KNOWN IF SYNDROS IS SAFE AND EFFECTIVE IN CHILDREN.

Do not take SYNDROS if you:

  • had an allergic reaction to dronabinol. Signs and symptoms of an allergic reaction to dronabinol include: swelling of the lips, hives, a rash over your whole body, mouth sores, skin burning, flushing, and throat tightness.
  • had an allergic reaction to alcohol.
  • are using a medicine that contains disulfiram (Antabuse) or metronidazole (Pylera, Flagyl, Flagyl ER, Nuvessa, Vandazole) or have taken or received a medicine that contains disulfiram or metronidazole in the last 14 days.

Before taking SYNDROS, tell your doctor about all of your medical conditions, including if you:

  • have or had heart problems.
  • have or had problems with drug abuse or dependence.
  • have or had problems with alcohol abuse or dependence.
  • have or had mental health problems including mania, depression or schizophrenia.
  • have had a seizure or have a medical condition that may increase your risk of having a seizure.
  • are pregnant or plan to become pregnant. SYNDROS may harm your unborn baby. Avoid the use of SYNDROS if you are pregnant.
  • are breastfeeding or plan to breastfeed. The Centers for Disease Control and Prevention recommends that mothers with HIV not breastfeed because they can pass the HIV through their breast milk to the baby. It is not known if SYNDROS passes into your breast milk. Talk to your doctor about the best way to feed your baby if you take SYNDROS. Do not breastfeed while taking SYNDROS and for 9 days after your last dose of SYNDROS if you are being treated for nausea and vomiting caused by anti-cancer medicine.
TELL YOUR DOCTOR ABOUT ALL THE MEDICINES YOU TAKE OR HAVE TAKEN IN THE LAST 14 DAYS, INCLUDING PRESCRIPTION AND OVER-THE-COUNTER MEDICINES, VITAMINS, AND HERBAL SUPPLEMENTS. SYNDROS AND CERTAIN OTHER MEDICINES CAN AFFECT EACH OTHER, CAUSING SERIOUS SIDE EFFECTS.
