What is the Most Important Information I Should Know About Duopa

DUOPA can cause serious side effects, including:

  • Stomach and intestine (gastrointestinal) problems and problems from the procedure you will need to have to receive DUOPA (gastrointestinal procedure-related problems).

    Some of these problems may require surgery and may lead to death.

    • a blockage of your stomach or intestines (bezoar)
    • stopping movement through intestines (ileus)
    • drainage, redness, swelling, pain, feeling of warmth around the small hole in your stomach wall (stoma)
    • bleeding from stomach ulcers or your intestines
    • inflammation of your pancreas (pancreatitis)
    • air or gas in your abdominal cavity
    • skin infection around the intestinal tube, infection in your blood or abdominal cavity may occur, after surgery
    • stomach pain, nausea or vomiting
  • Tell your healthcare provider right away if you have any of the following symptoms of stomach and intestine problems and gastrointestinal procedure-related problems:
    • stomach (abdominal) pain
    • constipation that does not go away
    • nausea or vomiting
    • fever
    • blood in your stool or a dark tarry stool (melanotic stool)

You will need to have a procedure to make a small hole (called a “stoma”) in your stomach wall to place a gastro-jejunostomy tube (called a PEG-J tube) in an area of your small intestine called the jejunum. DUOPA is delivered directly to your small intestine through this tube. Your healthcare provider will talk to you about the stoma procedure. Before the stoma procedure, tell your healthcare provider if you have ever had a surgery or problems with your stomach.

Talk to your healthcare provider about what you need to do to care for your stoma. After the procedure, you and your healthcare provider will need to regularly check the stoma for any signs of infection.

If your PEG-J tube becomes kinked, knotted, or blocked this may cause you to have worsening of your Parkinson’s symptoms or recurring movement problems (motor fluctuations). Call your healthcare provider if your Parkinson’s symptoms get worse or you have slow movement while you are treated with DUOPA.

What is Duopa

DUOPA is a prescription medicine used for treatment of advanced Parkinson’s disease. DUOPA contains 2 medicines, carbidopa and levodopa.

DUOPA should not be given to children (younger than 18 years).

Who Should not use Duopa

Do not use DUOPA if you:

  • take a medicine called a nonselective Monoamine Oxidase (MAO) Inhibitor (such as phenelzine or tranylcypromine) or have taken a nonselective MAO Inhibitor within the last 14 days.
    Ask your healthcare provider or pharmacist if you are not sure if you take an MAO Inhibitor.

  • have had problems with fainting (syncope)

How Should I Use Duopa

  • Use DUOPA exactly as your healthcare provider tells you to use it.
  • Your healthcare provider should show you how to use DUOPA before you use it for the first time. Ask your healthcare provider or pharmacist if you have any questions.
  • Your prescribed dose of DUOPA will be programmed into your pump by a healthcare provider and should only be changed by your healthcare provider or while you are with your healthcare provider.
  • Do not stop using DUOPA or change your dose unless you are told to do so by your healthcare provider. Tell your healthcare provider if you develop withdrawal symptoms such as fever, confusion, or severe muscle stiffness.
  • Keep a supply of oral carbidopa-levodopa immediate release (IR) tablets with you in case you are unable to give your DUOPA infusion.
  • DUOPA is given continuously over 16 hours through a tube that is put into your stomach called a PEG-J. A small pump (CADD-Legacy 1400) is used to move DUOPA from the medication cassette through your PEG-J tube.
  • Your DUOPA dose has three parts:
    • a morning dose
    • a continuous dose
    • extra doses
  • DUOPA can also be given for a short time (short-term) through a tube put into your nose called a naso-jejunal (NJ) tube.
  • The CADD-Legacy 1400 portable infusion pump should be used to give DUOPA through your PEG-J tube. See the Instructions for Use that comes with your CADD-Legacy 1400 portable infusion pump for complete instructions on how to use the pump.
  • DUOPA comes in a small plastic container (cassette) that you connect to the pump to get your medicine.
    • Each cassette can only be used 1 time. An opened cassette should not be reused.
    • The cassette should not be used for longer than 16 hours.
    • The cassette should be thrown away at the end of the infusion, even if there is some medicine still in the cassette.
  • Disconnect the pump from your PEG-J tube after the 16 hour dosing time is finished. Use a syringe filled with room temperature water to flush your PEG-J tube. See the “Instructions for Use” for more information about how to flush your PEG-J tube with a syringe.
  • After your daily DUOPA infusion, you should take your usual night-time dose of oral carbidopa-levodopa tablets as prescribed.
  • If you stop your DUOPA infusion for more than 2 hours during your 16 hour dosing time for any reason, call your healthcare provider and take oral carbidopa-levodopa as prescribed until you are able to restart your DUOPA infusion.
  • If you stop your DUOPA infusion for less than 2 hours, you do not need to take oral carbidopa-levodopa, but your healthcare provider may tell you to take an extra dose of DUOPA.

What Should I Avoid While Using Duopa

  • Do not drive, operate machinery, or do other activities until you know how DUOPA affects you. Sleepiness and falling asleep suddenly caused by DUOPA can happen as late as 1 year after you start your treatment.

What are the Possible Side Effects of Duopa

DUOPA may cause serious side effects, including:

  • See “What is the most important information I should know about DUOPA?”

    • You could fall asleep without any warning.
    • Some people using DUOPA have had car accidents because they fell asleep while driving.
      Do not drive or operate machinery until you are sure how DUOPA affects you.
      Tell your healthcare provider if you take other medicines that can make you sleepy such as sleep medicines, antidepressants, or antipsychotics.
  • Low blood pressure when you sit or stand up quickly. After you have been sitting or lying down, stand up slowly until you know how DUOPA affects you. This may help reduce the following symptoms while you are using DUOPA:
    • dizziness
    • nausea
    • sweating
    • fainting
  • Seeing things that are not there, hearing sounds or feeling sensations that are not real (hallucinations). Hallucinations can happen in people who use DUOPA. Tell your healthcare provider if you have hallucinations.

    If you or your family members notice that you are having unusual urges or behaviors, talk to your healthcare provider.
  • Depression and suicide. DUOPA can cause depression or make your depression worse. Pay close attention to sudden changes in your mood, behavior, thoughts, or feelings. Call your healthcare provider right away if you feel depressed or have thoughts of suicide.
  • Uncontrolled sudden movements (dyskinesia). If you have new dyskinesia, or your dyskinesia gets worse, tell your healthcare provider. This may be a sign that your dose of DUOPA or other medicines to control your Parkinson’s disease may need to be adjusted.
  • Progressive weakness or numbness or loss of sensation in the fingers or feet (neuropathy).
  • Heart attack or other heart problems. Tell your healthcare provider if you have experienced increased blood pressure, a fast or irregular heartbeat or chest pain.
  • Skin cancer (melanoma). Parkinson’s disease may be associated with a higher chance of having melanoma than people who do not have Parkinson’s disease. It is not known if the chance of having melanoma is higher because of the medicines used to treat Parkinson’s disease, like DUOPA, or from the Parkinson’s disease. People who use DUOPA should have their skin checked regularly for melanoma by a qualified healthcare professional.
  • Abnormal blood tests. DUOPA may cause changes in certain blood tests, especially certain hormone and kidney function blood tests.
  • Worsening of the increased pressure in your eyes (glaucoma). The pressure in your eyes should be checked after starting DUOPA.

    • swelling of legs and feet
