Before treatment initiation, and during maintenance with JAKAVI, it is important to:5

  • Perform a complete blood count, including white blood cell count differential, followed by monitoring every 2–4 weeks until doses are stabilised and then as clinically indicated
  • Titrate the dose based on safety and efficacy according to the SmPC, discontinuing treatment for platelet counts <50,000/mm3 or absolute neutrophil counts <500/mm3
  • Test patients for tuberculosis and hepatitis B virus, and resolve any pre-existing active serious infections prior to treatment initiation
  • Perform periodic skin examinations for patients with an increased risk of skin cancer
  • Monitor lipid levels and treat according to guideline recommendations
  • Consult the SmPC for JAKAVI contraindications and possible drug–drug interactions
