trikeAccordingly asks:
What can a patient do to prevent K-bladder?
Answer from Dr. Ben Yudkoff, Co-Founder and Chief Medical Officer of Lumin Health:
K-bladder, or ulcerative cystitis, is a condition that occurs when ketamine and its breakdown products – norketamine/hydroxynorketamine – irritate the lining of the bladder. There are \*very few\* examples of this happening when people are taking the medication in a medical protocol. There is one article published a couple of years back as a case report…. The incidence of ulcerative cystitis is very low when the exposure to ketamine/esketamine occurs in the context of a treatment protocol. That said, for people who are worried, I recommend hydrating after treatment – good for the body, in general, and also to help flush the bladder – and watching for symptoms.
