It is not known if REZLIDHIA is safe and effective in children.


REZLIDHIA can cause serious side effects including:

  • Differentiation Syndrome. Differentiation syndrome is a condition that affects your blood cells and may be life-threatening or lead to death.

If you develop signs and symptoms of differentiation syndrome, your healthcare provider may treat you with a corticosteroid medicine or a medicine called hydroxyurea and may monitor you in the hospital.

  • Liver problems. Changes in liver function tests are common during treatment with REZLIDHIA and can be serious. Your healthcare provider will do blood tests to check your liver function before and during treatment with REZLIDHIA.

    • yellowing of your skin or the white part of your eyes (jaundice)
    • dark “tea-colored” urine
