Doptelet is an oral tablet used to treat low platelet count, which may cause excessive bleeding. The generic name of Doptelet is avatrombopag. In this article, we will discuss its uses, mechanism of action, side effects, cost, and more.

Doptelet Quick Facts:

• Doptelet is part of the medication class called thrombopoietin (TPO) receptor agonists.
• This medication is only available by prescription from a healthcare provider.

What Is Doptelet?

Doptelet is a brand-name prescription medication. The active ingredient in this product is avatrombopag, which belongs to the medication class called thrombopoietin (TPO) receptor agonists. 

It works just like a natural protein in the liver called thrombopoietin, which causes the body to make more platelets. Platelets, or thrombocytes, are blood cells that help blood clot to stop bleeding. 

What Is Doptelet Used For?

The FDA approved this medication to raise platelet count in adults with:

• Chronic (long-term) liver disease who are scheduled to undergo a surgical (including dental) or other procedures (e.g., endoscopy). 
• Chronic 면역 혈소판 감소증 (or ITP) unresponsive to other treatments. 

Doptelet is used to raise your platelet count to a level of about 50,000 platelets per microliter, which is the acceptable level that keeps your risk of serious bleeding low. However, it’s not used to restore your platelet counts to normal levels. 

The safety and efficacy of this medication in children have yet to be determined. 

Off-Label Use

“Off-label use” is when a healthcare provider prescribes a medication for non-FDA-approved uses. 

This medication may be used “off-label” for individuals with aplastic anemia and chemotherapy-induced thrombocytopenia [1, 2].

Note that this is an early finding, and more research is needed to establish safety and efficacy. 

How To Use Doptelet Properly

This medication is available as an oral tablet that’s taken by mouth. Each tablet contains 20 milligrams (mg) of the active drug. 

Take the dosage exactly as prescribed and at the same time each day. Don’t take less, more, or take the medication for longer than prescribed. 

Never stop taking this medication without talking to your healthcare provider first. Doing so can raise your risk of serious bleeding if you become injured.

Follow the instructions on the prescription label. If you’re not sure how to take the medication, ask your prescriber or pharmacist for help.

Swallow the tablet whole with about 8 ounces of water. Also, take this medication with food.

Inform your healthcare provider if you:

• Are allergic to avatrombopag or any product component
