What should I avoid while taking SYNDROS?

Do not drive, operate machinery, or do other dangerous activities until you know how SYNDROS affects you. SYNDROS taken with medicines that cause dizziness, confusion, and sleepiness may make these symptoms worse.

What are the possible side effects of SYNDROS? SYNDROS may cause serious side effects, including:

  • Seizures. SYNDROS may increase your risk of seizures. Stop taking SYNDROS and call your doctor and get medical care right away if you have a seizure during treatment with SYNDROS.
  • Drug and alcohol abuse. You may have an increased risk of abusing SYNDROS if you have a history of drug or alcohol abuse or dependence, including marijuana. Tell your doctor if you develop abuse behaviors such as increased irritability, nervousness, restlessness or want more or higher doses of SYNDROS during your treatment.
  • Nausea, vomiting, or stomach-area (abdominal) pain. Tell your doctor if you have nausea, vomiting, or abdominal pain or if your nausea, vomiting, or abdominal pain gets worse during treatment with SYNDROS. The most common side effects of SYNDROS include:
    • stomach-area (abdominal) pain

    • feeling extremely happy (euphoria)
    • nausea
    • overly suspicious or feeling people want to harm you (paranoid reaction)
    • sleepiness
    • abnormal thoughts
    • vomiting

These are not all the possible side effects of SYNDROS. Tell your doctor if you have any side effect that bothers you or does not go away. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

What is a Prior Authorization (PA)?

Prior Authorization is a process used by health insurance companies, Managed Care Organizations (MCOs), and third-party payers to determine whether they will cover prescribed medicines and/or procedures. There are a number of different reasons why payers require prior authorization. Some of these include an assessment of medical necessity and resource utilization reviews.

How does the Prior Authorization process work?

  1. A healthcare provider prescribes a medication.
  2. The prescription is presented at the pharmacy.
  3. The pharmacist enters the medication information into the computer system.
  4. The pharmacist may receive notification from an MCO that a Prior Authorization is required (the prescription is denied until a healthcare provider provides a justification as to why the medication is needed).
  5. The pharmacist informs the adult patient and calls the healthcare provider’s office.
  6. The healthcare provider then either allows the pharmacist to switch to a medication currently approved by the MCO, or informs the pharmacist he or she will request approval from the MCO (the Prior Authorization).
  7. The healthcare provider completes the appropriate forms and/or calls the MCO to seek approval.
  8. The MCO either approves or denies the request for medication. If denied, the healthcare provider and the adult patient may appeal the denial.

What does an adult patient have to do to seek Prior Authorization approval for SYNDROS?

Nothing. A healthcare provider or a staff member in their office will work with a Specialty Pharmacy that offers Prior Authorization Assistance.

What if the Prior Authorization is denied?

If a Prior Authorization is denied, a healthcare provider and/or the adult patient can appeal the denial to the MCO by resubmitting the Prior Authorization form and offering additional medical justification. If an adult patient and/or healthcare provider disagrees with the MCO denial, they may request an external review from a state board.
