Thank you Miyuru, I am worried pricnipally about toxicity in kidneys and if it is an absolutely contraindication.

It depends on the clerance I think. If it was a kidney faillure after a high dose but clerence ok now  I think you can go back to lithium with few wories.

Thank you Aida, the clearance is not the better but we are going to go back to lithium slowly and being aware

In my Hospital we suggest to do a kydney MRI to search for microkyst which risk to counter-indicate lithium if ckd-epi is < 60.
