Doptelet is used to treat thrombocytopenia (a lack of platelets in the blood) in adults with chronic liver disease who are scheduled to undergo a medical procedure.

A low platelet count increases the risk of excessive bleeding during certain medical procedures. Avatrombopag increases the production of platelets by your body to help prevent too much bleeding.

Doptelet is also used to treat low blood platelet counts in adults with chronic immune thrombocytopenia (ITP) when other treatments have not worked well enough.

Doptelet is also used to treat chronic immune thrombocytopenia when other treatments have failed.

Doptelet is not a cure for thrombocytopenia and it will not make your platelet counts normal in adults with chronic liver disease or chronic immune thrombocytopenia.

Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.

Take Doptelet exactly as it was prescribed. Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Use the medicine exactly as directed.

Doptelet is usually taken once daily to treat chronic immune thrombocytopenia.

When given before a medical procedure in people with chronic liver disease: Doptelet is usually taken once daily for 5 days, beginning 10 to 13 days before your procedure. Carefully follow your doctor's dosing instructions about the timing of this medicine and the procedure.
