Hi, I haven't heard of anyone on this combo but, it might be beneficial. What dose of anagrelide are you currently taking? Have you tried a lower dose anagrelide to see if the effects on your heart go away?

That's a great question to bring to this community! While personal experiences from other myMPNteam members with that specific combination aren't available here right now, some helpful background on both medications can be shared.

That's a great question to bring to this community! While personal experiences from other myMPNteam members with that specific combination aren't available here right now, some helpful background on both medications can be shared.

Both drugs target platelets but work differently:

- Hydroxyurea reduces production of *all* blood cell types in the bone marrow, making it broadly useful for ET
- Anagrelide is much more targeted — it specifically lowers platelet counts by reducing megakaryocytes (the cells that produce platelets), without affecting red or white blood cells Some side effects to be aware of with each:

Hydroxyurea may cause:
- Low red or white blood cell counts
- Nosebleeds, bleeding gums, or easy bruising
- Diarrhea, constipation, or darkened skin
- Increased skin cancer risk — sun protection is important

Anagrelide may cause:
- Headaches
- Fluid retention (swelling)
- Diarrhea Since everyone's response to treatment is unique, keeping close contact with your treatment team is really important — typically follow-ups every three to four months, or more frequently if symptoms change.

Bringing that study to your next appointment sounds like a smart move! Your hematologist can help weigh whether this combination makes sense for your specific situation. 👍

I’m currently taking both meds. 1500 mg HU and 3mg of Anagrelide each day. It’s only been 3 weeks since the Anagrelide changed from .5 mg to 1 mg, and my next lab isn’t until next week. The only thing I’m noticing is increased coughing. I don’t know if this is because of the meds or the summer allergies.
