Frequently asked questions about ZEPOSIA

It’s important to tell your UC healthcare provider about any other medicines or supplements that you’re taking or have recently taken, including:

  • Prescription medicines
  • Over-the-counter medicines
  • Vitamins
  • Herbal supplements

Using ZEPOSIA with other medicines can cause serious side effects.

Especially tell your UC healthcare provider if you take or have taken other medicines, such as:

  • Medicines that affect your immune system, such as alemtuzumab
  • Medicines to control your heart rhythm (also called antiarrhythmics) or heartbeat
  • CYP2C8 inducers such as rifampin
  • CYP2C8 inhibitors, such as gemfibrozil (medicine to treat high fat in your blood)
  • Opioids (pain medicine)
  • Medicines to treat depression
  • Medicines to treat Parkinson's disease
  • Medicines to control your heart rate and blood pressure (beta blocker medicines and calcium channel blocker medicines)
  • Medicines called monoamine oxidase (MAO) inhibitors (such as selegiline, phenelzine, or linezolid)

Before you start taking ZEPOSIA, your doctor will request a few routine tests.

An electrocardiogram (ECG)—a common test that monitors your heart and makes sure it’s working normally before you start treatment

Blood work—including complete blood count and liver function test

Eye and Skin Exam—recommended near the start of treatment to monitor any potential changes while taking ZEPOSIA

Be sure to review your vaccination records to ensure immunizations are up to date with current guidelines, and discuss your list of current or prior medication, vitamins, and herbal supplements with your doctor prior to starting treatment.

How long will the medical tests take?

If you plan to complete all of the tests in one visit at a healthcare provider’s office, it may take as little as 1 hour to complete.

You should not receive live vaccines during treatment with ZEPOSIA, for at least 1 month before taking ZEPOSIA, and for 3 months after you stop taking ZEPOSIA. Vaccines may not work as well when given during treatment with ZEPOSIA.

Talk to your UC healthcare provider before receiving any vaccines while on ZEPOSIA.

See the question below for information about the varicella zoster virus (VZV) vaccine and taking ZEPOSIA.

Your doctor may require you to receive the varicella zoster virus (VZV) vaccine, also known as the chicken pox vaccine, before you take ZEPOSIA. The VZV vaccine includes two doses. If you haven't received the VZV vaccine in the past, you may need to postpone the start of treatment with ZEPOSIA.

If you're unsure of your vaccination status, there is a test that can determine whether or not you've already received the VZV vaccine, have had chickenpox, or have received the vaccine for chickenpox. Your healthcare provider may do a blood test for the chickenpox virus. You may need to get the full course of the vaccine for chickenpox and then wait 1 month before you start taking ZEPOSIA.

You should take ZEPOSIA exactly as prescribed by your UC healthcare provider.

If you miss 1 or more doses during the first 14 days of treatment, contact your UC healthcare provider. You'll need a new 7-day Starter Pack to restart treatment. This will allow you to increase your dosage gradually to help avoid a decrease in heart rate, which is a possible serious side effect of ZEPOSIA.

If you miss a dose after the first 14 days of treatment, take your scheduled dose (1 pill) the next day at your usual time.

A missed dose is when you don’t take ZEPOSIA on the scheduled day your doctor has prescribed.

You and your healthcare professional should work together to make sure ZEPOSIA is right for you before starting treatment. Be sure to let your healthcare professional know if you have any of these conditions or do not know if you have any of these conditions before taking ZEPOSIA:

  • Have had a heart attack, chest pain (also known as unstable angina), a stroke or mini-stroke (also known as transient ischemic attack or TIA), or certain types of heart failure in the last 6 months
  • Have or have had a history of certain types of irregular or abnormal heartbeat (also known as arrhythmia) that is not corrected by a pacemaker
  • Have untreated, severe breathing problems during your sleep (also known as sleep apnea)
  • Take certain medicines called monoamine oxidase (MAO) inhibitors (eg, selegiline, phenelzine, linezolid)

Talk with your healthcare provider if you are pregnant or plan to become pregnant. If you are a female who can become pregnant, you should use effective birth control during your treatment with ZEPOSIA and for 3 months after you stop taking ZEPOSIA.

Tell your healthcare provider right away if you become pregnant while taking ZEPOSIA or if you become pregnant within 3 months after you stop taking ZEPOSIA.

If you are a female who can become pregnant, you should use effective birth control during your treatment with ZEPOSIA and for 3 months after you stop taking ZEPOSIA. Talk with your healthcare provider about what birth control method is right for you during this time.
