Iclusig (Ponatinib Hydrochloride)
Complete patient guide for uses, dosage, side effects, and safety information
Quick Facts
What Is Iclusig Used For?
Iclusig is a targeted cancer medication that treats specific types of blood cancers called leukemia. It works by blocking signals that tell your body to produce abnormal white blood cells.
Primary Uses
Iclusig treats adults with chronic myeloid leukemia (CML) and Philadelphia-chromosome positive acute lymphoblastic leukemia (Ph+ ALL) who are no longer benefiting from other treatments. Both conditions involve too many abnormal white blood cells in the blood and bone marrow.
How It Works
In patients with these leukemias, changes in DNA trigger signals that tell the body to produce abnormal white blood cells. Iclusig blocks these signals, stopping the production of these abnormal cells. It targets an abnormal chromosome called the Philadelphia chromosome that’s present in both conditions.
Specialist Care Required: This medicine is only prescribed by doctors experienced in leukemia treatment and requires regular monitoring.

How to Take Iclusig
Take Iclusig exactly as prescribed by your doctor. The dose may be adjusted based on how you respond to treatment and any side effects you experience.
Dosage Instructions
The recommended starting dose is one 45 mg tablet once daily. Take it at about the same time each day, with or without food. Swallow tablets whole with water – do not crush or dissolve them. Your doctor may reduce your dose or temporarily stop treatment if you develop certain side effects or blood count changes.
What If You Miss a Dose?
If you miss a dose, take it as soon as you remember and then return to your normal schedule. If it’s less than 12 hours before your next dose, skip the missed dose and take your next dose at the regular time. Never take a double dose to make up for a missed one.
Important: Never double dose if you miss a dose – this may increase the chance of serious side effects.
