What is JAKAFI?
Ruxolitinib phosphate is a kinase inhibitor with the chemical name ()-3-(4-(7-pyrrolo[2,3-]pyrimidin-4-yl)-1-pyrazol-1-yl)-3-cyclopentylpropanenitrile phosphate and a molecular weight of 404.36. Ruxolitinib phosphate has the following structural formula:
Ruxolitinib phosphate is a white to off-white to light pink powder and is soluble in aqueous buffers across a pH range of 1 to 8.
Jakafi (ruxolitinib) Tablets are for oral administration. Each tablet contains ruxolitinib phosphate equivalent to 5 mg, 10 mg, 15 mg, 20 mg and 25 mg of ruxolitinib free base together with microcrystalline cellulose, lactose monohydrate, magnesium stearate, colloidal silicon dioxide, sodium starch glycolate, povidone and hydroxypropyl cellulose.
What does JAKAFI look like?
What are the available doses of JAKAFI?
Tablets: 5 mg, 10 mg, 15 mg, 20 mg and 25 mg. ()
What should I talk to my health care provider before I take JAKAFI?
How should I use JAKAFI?
Jakafi is indicated for treatment of patients with intermediate or high-risk myelofibrosis (MF), including primary MF, post-polycythemia vera MF and post-essential thrombocythemia MF.
The recommended starting dose of Jakafi is based on platelet count (Table 1). A complete blood count (CBC) and platelet count must be performed before initiating therapy, every 2 to 4 weeks until doses are stabilized, and then as clinically indicated . Doses may be titrated based on safety and efficacy.

What should I look out for while using JAKAFI?
What might happen if I take too much JAKAFI?
There is no known antidote for overdoses with Jakafi. Single doses up to 200 mg have been given with acceptable acute tolerability. Higher than recommended repeat doses are associated with increased myelosuppression including leukopenia, anemia and thrombocytopenia. Appropriate supportive treatment should be given.
Hemodialysis is not expected to enhance the elimination of Jakafi.
How should I store and handle JAKAFI?
Jakafi (ruxolitinib) Tablets are available as follows:
Chemical StructureNo Image found
Ruxolitinib, a kinase inhibitor, inhibits Janus Associated Kinases (JAKs) JAK1 and JAK2 which mediate the signaling of a number of cytokines and growth factors that are important for hematopoiesis and immune function. JAK signaling involves recruitment of STATs (signal transducers and activators of transcription) to cytokine receptors, activation and subsequent localization of STATs to the nucleus leading to modulation of gene expression.
MF and PV are myeloproliferative neoplasms (MPN) known to be associated with dysregulated JAK1 and JAK2 signaling. In a mouse model of JAK2V617F-positive MPN, oral administration of ruxolitinib prevented splenomegaly, preferentially decreased JAK2V617F mutant cells in the spleen and decreased circulating inflammatory cytokines (e.g., TNF-α, IL-6).
A crossover study1 designed to assess the potential of a drug interaction between Dapsone, 100 mg/day and trimethoprim, 200 mg every 12 hours, in eight asymptomatic HIV positive volunteers (average CD4 count 524 cells/mm3) demonstrated that there was not a significant drug intreraction between Dapsone and trimethoprim. However, an earlier report2 also by Lee et al, in 78 HIV infected patients with acute pneumonia, receiving Dapsone, 100 mg/day and higher trimethoprim dose, 20 mg/kg/day, demonstrated that the serum levels of Dapsone were increased by 40% and trimethoprim levels were increased by 48% when the drugs were administered concurrently.
Treatment with Jakafi can cause thrombocytopenia, anemia and neutropenia .
Manage thrombocytopenia by reducing the dose or temporarily interrupting Jakafi. Platelet transfusions may be necessary .
Patients developing anemia may require blood transfusions and/or dose modifications of Jakafi.
Severe neutropenia (ANC less than 0.5 X 10/L) was generally reversible by withholding Jakafi until recovery .
Perform a pre-treatment complete blood count (CBC) and monitor CBCs every 2 to 4 weeks until doses are stabilized, and then as clinically indicated .
