This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.

HOW should this medicine be used?

Maralixibat comes as a solution (liquid) to take by mouth. It is usually taken once a day, thirty minutes before the first meal of the day. Take maralixibat at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take maralixibat exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Your doctor may start you on a low dose of maralixibat and increase your dose after one week.

Use an oral syringe (measuring device) to accurately measure and take your dose of maralixibat solution. Ask your pharmacist for an oral syringe if one is not included with your medication. Do not use a household teaspoon to measure the solution. Replace each oral syringe after using it for 30 days or if it becomes damaged or hasn't been cleaned. Follow the manufacturer's instructions about how to clean the oral syringe. Ask your doctor or pharmacist if you if you have any questions.

Follow these steps to measure the dose using the syringe provided:

1. Open the bottle by pushing down on the cap and turning the cap at the same time.
2. Push the plunger of the measuring device completely down to the tip.
3. Insert the tip of the measuring device firmly into the opening on the top of the bottle.
4. Turn the bottle (with the measuring device attached) upside down.
5. Pull back on the plunger slowly until the amount of liquid prescribed by your doctor fills the measuring device to the appropriate marking. If you are not sure how to correctly measure the dose your doctor has prescribed, ask your doctor or pharmacist.
6. Turn the bottle (with the measuring device attached) right-side up and slowly remove the measuring device.
7. Take maralixibat directly into your mouth from the measuring device; you should do this while sitting or standing.
8. Replace the cap on the bottle and close tightly.
9. Follow the manufacturer's instructions about how to clean the oral syringe.
10. Call your doctor or pharmacist to find out how you should measure a dose of maralixibat solution if you do not have the measuring device that came with this medication.

Maralixibat controls itching caused by Alagille syndrome but does not cure it. Continue to take maralixibat even if you feel well. Do not stop taking maralixibat without talking to your doctor.

Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.

What should I know about STORAGE and DISPOSAL of this medication?

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).

Keep this medication closed tightly and dispose of any unused medication 45 days after first opening the container.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community.
