Omacetaxine (Subcutaneous route)
Uses of This Medicine:
Omacetaxine injection is used to treat chronic or accelerated phase chronic myeloid leukemia (CML). It is used in patients who have already received medicines for CML that did not work well. Leukemia is a type of cancer where the body makes abnormal white blood cells.
Omacetaxine is an antineoplastic (cancer) medicine. It interferes with the growth of cancer cells, which are eventually destroyed by the body. Since the growth of normal cells may also be affected by omacetaxine, other side effects can occur. Before you begin treatment, talk to your doctor about the benefits of this medicine as well as the possible risks of using it.
This medicine is to be given only by or under the direct supervision of a doctor.

Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals.

Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.
