Hello @michellem55,
Thanks for posting.
It’s understandable that you’re concerned about the possible effects of mirtazapine on your white blood cell count as you are already taking ribociclib.
A reduction in the white cell count is not a common side effect of mirtazapine. There is some evidence that bone marrow suppression may occur when taking mirtazapine and this could cause a reduction in the white cell count. However, this is not a common side effect and there is not enough data available to say how often this might happen. As your blood counts will be being monitored during your treatment with ribociclib any change should be picked up quickly by your treatment team.
In some people ribociclib may cause an increase in the blood levels of mirtazapine leading to a possibility of increased side effects. Before starting any new medication or supplement it’s important for you to discuss it with your treatment team.
You’ve said that you have an appointment with your oncologist but, in the meantime, you may wish to discuss this with your hospital oncology pharmacist (by going through the hospital switchboard) who will be able to give more information. You could also contact your breast care nurse for advice. You do not have to wait until your oncology appointment.
