I was diagnosed with polycythemia Vera in February 2026. Currently on 1000mg of hydroxyurea and 81 mg aspirin daily.
I also have hypothyroidism - 20 plus years - and on 100 mcg levothyroxine daily. My TSH levels have been stable for years. Last result in September was 3.76. In prep for my annual physical I had the usual lab tests ordered last week. My TSH levels jumped to 6.86, out of normal range.
Reading up on drug interactions with HU, there doesn’t appear to be any issues with levothyroxine. I take the levothyroxine in the morning and the HU at night.
Has anyone with PV experienced problems with their thyroid?
