What Is Doptelet? Uses, Dosage, and What You Need to Know in 2026

Doptelet (avatrombopag) is an FDA-approved oral medication used to treat low platelet counts in specific patient populations. If your doctor has prescribed Doptelet or you've been diagnosed with a condition that might require it, here is a complete overview of what Doptelet is, what it treats, and what you need to know before you start.

What Is Doptelet?

Doptelet is the brand name for avatrombopag, a thrombopoietin receptor agonist (TPO-RA). It stimulates the body's bone marrow to produce more platelets — the blood cells responsible for clotting and preventing bleeding. Doptelet comes as a 20 mg oral tablet and as Doptelet Sprinkle (oral granules for young children). It was first approved by the FDA on May 21, 2018.

Doptelet is a second-generation TPO-RA, meaning it was developed to improve on earlier medications in its class. One key advantage is that Doptelet does not chelate (bind to) polyvalent cations like iron, calcium, or magnesium — which means unlike Promacta (eltrombopag), it can be taken with food. This makes dosing more flexible and convenient for patients.

What Conditions Does Doptelet Treat?

As of 2026, Doptelet is FDA-approved to treat:

Thrombocytopenia in adults with chronic liver disease (CLD) who are scheduled to undergo a medical or dental procedure. Chronic liver disease (cirrhosis) can cause low platelet counts. Doptelet is given as a 5-day course before the procedure to raise platelets to a safer level.

Chronic immune thrombocytopenia (ITP) in adults when other treatments haven't worked well enough. ITP is an autoimmune disorder where the immune system destroys platelets. Doptelet is taken as an ongoing daily therapy with dose adjustments based on platelet counts.

Persistent or chronic ITP in pediatric patients 1 year and older who have had an insufficient response to prior therapy. This indication was approved in July 2025.

Doptelet Dosage: How Much Do You Take?

Doptelet dosing depends on why you are taking it:

CLD with platelet count below 40,000/µL: 60 mg (three 20 mg tablets) once daily for 5 consecutive days. This is the 60 mg daily dose carton — a 15-tablet blister pack.

CLD with platelet count 40,000–49,999/µL: 40 mg (two 20 mg tablets) once daily for 5 consecutive days.

ITP in adults: Start at 20 mg once daily. Dose adjustments are made based on platelet count response. Target platelet count is ≥50×10⁹/L.

ITP in pediatric patients (ages 6 and older): Weight-based dosing per prescribing information; starting at 20 mg once daily.

ITP in young children (ages 1 to <6, Doptelet Sprinkle): Doptelet Sprinkle oral granules at 10 mg per day for children in this age group; dose may be adjusted.

How to Take Doptelet

Follow these key instructions when taking Doptelet:

Take WITH food: Doptelet should be taken with a meal. Taking it with food reduces variability in how much of the drug your body absorbs, and may also reduce nausea.

Take at the same time every day: For ITP maintenance therapy, consistent daily timing helps maintain steady drug levels. Set an alarm as a reminder.

Don't skip doses for CLD: Completing all 5 doses of the CLD course is essential. A missed dose might mean your platelet count won't reach the target level in time for your procedure, requiring you to restart the course.

Keep tablets in original blister pack: Store at room temperature (68–77°F). Keep each tablet in its foil pack until you're ready to take it.

What Is the Doptelet 60 mg Daily Dose Carton?

You may have heard about a '60 mg daily dose carton' for Doptelet. This refers to the 15-tablet blister pack that contains exactly enough Doptelet for the 60 mg/day, 5-day treatment course for CLD patients with very low platelet counts (below 40,000/µL). Each dose consists of three 20 mg tablets taken together once daily. The 15-tablet carton ensures patients get exactly the right amount for this specific treatment course.

Is Doptelet Available as a Generic?

No. As of 2026, Doptelet (avatrombopag) is available only as a brand-name medication. There is no FDA-approved generic equivalent. This contributes to its high wholesale cost of approximately $12,657 for 30 tablets. However, manufacturer savings programs through Doptelet Connect are available to help commercially insured and financially eligible patients manage costs.

How Does Platelet Monitoring Work While on Doptelet?

Your doctor will check your platelet count regularly while you're taking Doptelet. For CLD: platelet counts are checked the day before and the day of your procedure. For ITP: platelet counts are checked weekly until you reach your target level, then monthly after that. Dose adjustments for ITP are based on your platelet count — if your platelets rise too high, your dose will be reduced to lower the risk of blood clots.
