1. What is Doptelet and what is it used for
Doptelet contains the active substance avatrombopag. It belongs to a group of medicines known as thrombopoietin receptor agonists.
Doptelet is used in adults with chronic liver disease to treat low platelet counts (thrombocytopenia) before undergoing a medical procedure where there is a risk of bleeding.
Doptelet is used to treat adults with low platelet counts due to primary chronic immune thrombocytopenia (ITP) when previous treatment for ITP (such as corticosteroids or immunoglobulins) has not worked well enough.
Doptelet helps increase the platelet count in the blood. Platelets are blood cells that help the blood to clot to reduce or prevent bleeding.
2. What you need to know before you take Doptelet
Do not take Doptelet:
- if you are allergic to avatrombopag or any of the other ingredients of this medicine (listed in section 6). If you are not sure, talk to your doctor or pharmacist before taking Doptelet.
Warnings and precautions
Talk to your doctor or pharmacist before starting Doptelet if:
- you are at risk of blood clots in the veins or arteries, or your family members have had blood clots.
- you have another blood disorder known as myelodysplastic syndrome (MDS); taking Doptelet may worsen MDS.
It is possible that the risk of blood clots may increaseas you get older if:
- you have been bedridden for a long time.
- you have cancer.
- you are taking birth control pills or hormone replacement therapy.
- you have recently undergone surgery or had an injury.
- you are overweight.

- you have advanced chronic liver disease.
If any of the above applies to you (or you are not sure), talk to your doctor or pharmacist before taking Doptelet.
Blood tests for platelet count
If you stop taking Doptelet, your platelet count is likely to decrease to the level before treatment or even below that, with a risk of bleeding. This can happen within days. Your platelet count will be monitored and your doctor will discuss the appropriate precautions with you.
Tests to check the bone marrow
In people with bone marrow problems, medicines like Doptelet may worsen these problems. Signs of changes in the bone marrow may appear as abnormal blood test results. Your doctor may also perform tests to directly examine the bone marrow during treatment with Doptelet.
