I am 79 and was also diagnosed with ET JAK2 in June 2022. I was already on a blood thinner for AFib. My platelets had been slowly rising.

At my first visit to hematologist my platelets had jumped to 735. I was put immediately on 500 mg Hydroxyurea daily. I experienced lightheaded feeling and a first ever vertigo attack. I saw an ENT and had several negative tests.

Right now I am taking 500 mg 4 days a week. My hematologist keeps saying she wants to get my platelets below 400 range. Last lab was 564. I have no lightheaded feelings now.

Best wishes, Eileen
