Why is this medication prescribed?
Avatrombopag is prescribed to people with chronic (ongoing) liver disease who are scheduled to undergo a medical or dental procedure in order to treat thrombocytopenia (a low number of platelets [type of blood cell needed for blood clotting]). This is done in order to help prevent complications related to bleeding. Additionally, it is used to treat thrombocytopenia in patients with persistent immune thrombocytopenia (ITP; a disorder that may result in unusual bleeding or bruising due to an unusually low amount of platelets in the blood) who did not respond to another form of treatment. Thrombopoietin (TPO) receptor agonists are a group of drugs that includes avatrombopag. It functions by increasing the body’s platelet production.
How should this medicine be used?
A tablet to be swallowed with food contains avatrombopag. It is typically taken once day with food for five days, beginning 10 to 13 days before the surgery, for the treatment of thrombocytopenia in persons with chronic liver disease who are scheduled to undergo a procedure. It is typically given once day with food for the duration of the prescribed period to treat thrombocytopenia in ITP patients. Avatrombopag should be taken every day at roughly the same time. Ask your doctor or pharmacist to explain any instructions on your prescription label that you are unsure about following. Avatrombopag should be taken as prescribed. Never take it in larger or less amounts or more frequently than directed by your doctor.
Your doctor will likely start you on a modest dose of avatrombopag for the treatment of thrombocytopenia in persons with ITP and may change your dose based on how you respond to the drug.

What should I know about storage and disposal of this medication?
Keep this medication out of the reach of children and properly closed in its original container. Store it at room temperature, away from extreme heat and moisture (not in the bathroom).
As many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and are simple for young children to open, it is crucial to keep all medications out of sight and out of reach of children. Always lock safety caps and promptly stash medication up and away from young children where it is out of their sight and reach to prevent poisoning. http://www.upandaway.org
Unused prescriptions must be disposed of carefully to prevent pets, kids, and other people from ingesting them. You should not, however, dispose of this medication in the toilet. Instead, utilising a medicine take-back programme is the easiest approach to get rid of your medication. To find out about take-back programmes in your area, speak with your pharmacist or the garbage/recycling department in your city. If you do not have access to a take-back programme, see the FDA’s Safe Disposal of Medicines website at http://goo.gl/c4Rm4p for additional information.

What other information should I know?
