Good morning, Jacklyn. I think the medication you’re referring to is Azacitidine (Vidaza). There are two forms of the drug so I don’t know if you’ll be on the oral pill or an injection.
Azacitidine oral is used to treat acute myeloid leukemia in people who are in remission but cannot finish other treatments for this condition and Azacitidine injection is used to treat certain types of bone marrow cancers and blood cell disorders.
Vidaza is often combined with venetoclax…that may be the pill you’re referring and taken along with Vidaza injections. Either way it is a combination with a proven track record to help treat AML, MDS, CMML Certain forms of MDS and CMML can progress to AML so the meds used for AML can be used to treat the latter two conditions.

There are several discussions in the forum with other members who have been on this combination of meds so I’ve posted a couple links to get you started:

I hope other members such as @beewoman70 @cblowers1 and @joesim might be able to share their experiences with you about having CMML and possible treatments.

This is so much change happening for you at one time and I know it’s unsettling. Believe me, I’ve been there. But I’ve also found that it’s important to not focus on statistics or time frames…thoughts like that waste precious time and only serve to stress us out. So my best advice is to find new meaning in every day and enjoy life to the fullest. 😉
When does your new treatment plan go into effect? Will you be able to stop the Hydroxy?
