Hi JennyRN70,
I have taken lamictal for quite some years and it has helped me a great deal. I have never taken abilify.
My kidney function is now 30% because of lithium and diabetes. Of course I have been on lithium for around 30 years. They are weening me off of it slowly -started 30 years ago on 1500 mg. and now down to 300mg. The thinking now is that you don't need such a high dosage of lithium to make it effective thus less of an effect on the kidneys. (lithium does not effect everyone's kidneys). So far I am doing fine with my moods since going lower in dosage. The pdoc believes that the lamictal is enough to allow this reduction in lithium and I believe him. When I started lithium lamictal was not around. I am not a doctor. What I have written may not work for you.
(am on a cocktail of drugs for my bi-polar II mental illness & been stable for quite a few years) I hope I haven't been too wordy.
