Question 1

What is Xromi?

Accepted Answer

Xromi is a formulation of hydroxyurea, a type of medicine known as an antimetabolite. It functions by interfering with the growth and division of cells or by altering the characteristics of certain blood components to help control the progression of various medical conditions.

Question 2

What is Xromi used for?

Accepted Answer

Xromi is used to treat chronic myeloid leukemia .

Question 3

How does Xromi work?

Accepted Answer

Mechanism of Action

Xromi contains hydroxyurea, a medication that helps manage sickle cell anemia by changing the composition of red blood cells. In people with this condition, red blood cells can become hard, sticky, and shaped like a sickle or crescent moon. These abnormal cells often get stuck in small blood vessels, blocking blood flow and causing intense pain or organ damage.

The primary way Xromi works is by:

Increasing fetal hemoglobin: It encourages the body to produce more fetal hemoglobin (HbF). This type of hemoglobin is usually present in high amounts at birth but decreases as a person grows.

Preventing sickling: Higher levels of fetal hemoglobin help prevent red blood cells from deforming into a sickle shape. This keeps the cells rounder and more flexible.

Improving blood flow: Because the cells stay flexible, they can move more easily through the blood vessels, which reduces the frequency of painful episodes and the need for blood transfusions.

While the exact biological process of how hydroxyurea increases fetal hemoglobin is not fully understood, it is also known to interfere with DNA synthesis by inhibiting an enzyme called ribonucleotide reductase. This action may also contribute to how the medication affects the production and behavior of blood cells.

Question 4

Accepted Answer

Common side effects of Xromi may include:

diarrhea

vomiting

nausea

Always consult with a healthcare professional about potential side effects.

Question 6

What drug class is Xromi?

Accepted Answer

Xromi belongs to the HMG-CoA reductase inhibitor drug class.

Question 7

What is the dosage of Xromi and how do I take it?

Accepted Answer

How to Take Xromi

Xromi is typically taken by mouth once a day at the same time each day. It can be taken with or without food. Because this medication is a liquid, it must be measured accurately using the oral dosing syringe provided by a pharmacist. Do not use a household spoon to measure the dose.

Handling Precautions

This medication is a cytotoxic drug, meaning it can be harmful if it comes into contact with your skin or if it is inhaled. Caregivers should follow these safety steps:

Wear disposable gloves when handling the bottle or the dosing syringe.

Wash your hands thoroughly before and after administering the medication.

If the solution spills, wipe it up immediately with a damp paper towel and dispose of it in a sealed plastic bag.

Avoid getting the liquid on your skin or in your eyes. If contact occurs, wash the area immediately with soap and water or flush eyes with water.

Missed Dose

If a dose is missed, it should be taken as soon as it is remembered. However, if it is almost time for the next scheduled dose, skip the missed dose and continue with the regular dosing schedule. Do not take two doses at the same time to make up for a missed one.

Question 8

Is Xromi safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

Xromi can cause fetal harm if taken during pregnancy. It is important to discuss pregnancy status and family planning with a healthcare provider before starting this medication. If pregnancy occurs during treatment, a clinician should be notified immediately.

Effective contraception is recommended for patients of reproductive potential:

Females: Use effective birth control during treatment and for at least 6 months after the final dose.

Males: Use effective birth control during treatment and for at least 1 year after the final dose. This medication may also impact male fertility.

Breastfeeding

Hydroxyurea is known to pass into breast milk. Due to the potential for serious adverse reactions in a nursing infant, breastfeeding is not recommended while taking Xromi. Patients should consult their healthcare provider to discuss the risks and determine the best feeding plan for their infant.

Question 9

What forms and strengths does Xromi come in?

Accepted Answer

Xromi is available in the following form:

Oral Solution: A liquid medication that is swallowed.

This medication is a liquid version of hydroxyurea. It is designed to be measured and taken by mouth using an oral dosing syringe.

Question 10

What is the FDA approval status of Xromi?

Accepted Answer

FDA Approval Status

Xromi (hydroxyurea) received FDA approval on September 27, 2021. It is approved for use in pediatric patients aged 2 years and older who have sickle cell anemia with recurrent moderate to severe painful crises. The primary goal of treatment is to reduce the frequency of these crises and the necessity for blood transfusions.

Boxed Warning

The FDA-approved labeling for Xromi includes a boxed warning regarding serious safety risks:

Severe Myelosuppression: Treatment with hydroxyurea can lead to dangerously low levels of white blood cells, red blood cells, and platelets. Healthcare providers must monitor blood counts weekly during the initial phase of treatment and periodically thereafter. Dosage adjustments or temporary discontinuation may be necessary if blood counts fall below specific levels.

Malignancies: Hydroxyurea is a known human carcinogen. Long-term use has been associated with the development of secondary cancers, including leukemia and skin cancer. Patients are encouraged to use sun protection and undergo regular skin examinations.

Usage and Monitoring

Because of the risks associated with this medication, it is typically prescribed by specialists experienced in managing sickle cell disease. Regular laboratory monitoring is a standard regulatory requirement for patients taking this drug to ensure safety and to adjust the dose based on the patient's weight and blood response.

Question 11

What should I know about Xromi and withdrawal?

Accepted Answer

Stopping Xromi

There is currently no evidence to suggest that Xromi causes physical dependence or a specific withdrawal syndrome when the medication is discontinued. Unlike certain other medications, such as opioids or sedatives, hydroxyurea does not typically require a tapering schedule to prevent physical illness upon stopping.

Risks of Discontinuation

While withdrawal symptoms are not expected, stopping Xromi can have significant effects on the condition being treated. You should not stop taking this medication without consulting your healthcare provider. Potential risks of stopping treatment include:

Recurrence of Symptoms: For patients with sickle cell anemia, stopping the medication may lead to an increase in the frequency and severity of painful crises.

Increased Transfusions: Discontinuing treatment may result in a higher need for blood transfusions.

Blood Count Changes: Xromi works by affecting the production of blood cells. When the drug is stopped, blood cell counts will eventually return to their baseline levels, which may affect the management of the underlying disease.

Your doctor will likely monitor your blood counts and overall health if you need to stop treatment to ensure your condition remains stable.
