Long term medication Hydroxyurea

Hello
I was recently diagnosed with the JAK 2 mutation. My hematologist prescribed 500 mg of Hydroxyurea 2 times a day.
I just started taking it 6 days ago. So far I haven’t had any side effects, maybe stomach upset but I also have diverticulitis so it’s hard to tell.
I’m really grateful for this support group. So many of my questions have been answered by reading through the posts.
Most of all it’s nice to find others who know what’s going on, none of my family & friends understand this.
Thank you
