Vesanoid is primarily intended to treat acute promyelocytic leukemia (APL), a type of cancer. In this condition, an abnormal number of white blood cells proliferate in the bone marrow. This drug is a retinoid derived from vitamin A and belongs to the retinoids class.

It is usually prescribed to adult patients with APL, an aggressive form of rare leukemia. Vesanoid is not recommended for children or individuals with other types of leukemia.

The drug promotes the differentiation of immature white blood cells into more mature and functional ones in the bone marrow. APL causes severe health complications due to abnormal white blood cells that cannot function correctly.

Acute Promyelocytic Leukemia (APL)

APL is a type of acute myeloid leukemia (AML) that primarily affects the promyelocytes, a type of white blood cell. These cells are essential for our immune system and play a crucial role in fighting infections. However, when they become cancerous, they can multiply uncontrollably, crowding out healthy blood cells.

Early detection of APL is paramount to successful treatment. Common symptoms include easy bruising, bleeding, fatigue, and an increased risk of infections. If you or someone you know experiences these symptoms, it is essential to seek medical attention promptly.

The good news is that APL is one of the most curable forms of leukemia. Treatment often involves a combination of chemotherapy and targeted therapy. All-trans retinoic acid (ATRA) is a medication commonly used to target the specific genetic mutations associated with APL.

In the realm of pharmaceuticals, precision and accuracy in medication dosing are paramount to ensure the best possible outcomes for patients. When it comes to Vesanoid, a medication widely used in the treatment of acute promyelocytic leukemia (APL), adhering to proper dosing guidelines is of utmost importance.

Initial Dosing

When embarking on a Vesanoid treatment plan, the initial dosing phase plays a pivotal role in laying the foundation for success. The recommended starting dose for adult patients with APL is typically 45 mg/m² per day, divided into two equal doses. This dosage should be administered orally.

For pediatric patients, the initial dose may vary depending on factors such as age, weight, and overall health. It’s crucial to consult with a healthcare professional who can determine the most appropriate initial dosage for young patients.

Maintenance Dosing

After the initial phase, the patient will transition into the maintenance dosing stage. This step is crucial for preventing the recurrence of APL and ensuring the disease remains in remission.

Maintenance dosing for Vesanoid typically consists of the same daily dosage as the initial phase, which is 45 mg/m², administered in two divided doses. The duration of the maintenance phase is determined by the treating physician and is based on the individual patient’s response to the medication.

Missed Doses

In any medical regimen, adherence to the prescribed dosage schedule is essential. If a dose of Vesanoid is missed, it’s vital to take action promptly. However, it’s equally important not to double the next dose to make up for the missed one.

If a patient realizes they’ve missed a dose, they should take it as soon as they remember, unless it’s close to the time for the next scheduled dose. In that case, they should skip the missed dose and continue with their regular dosing schedule. Patients should not attempt to “catch up” by taking extra medication.


While strict adherence to dosing guidelines is crucial, it’s equally important to avoid any possibility of an overdose. An overdose of Vesanoid can have severe consequences and may require immediate medical attention.

Symptoms of an overdose may include nausea, vomiting, headache, confusion, and an increased risk of bleeding.
