I'm on clozapine and also have urinary incontinence although for me it is only at night. I will say that it has improved somewhat over time although I would never sleep without an incontinence pad. I think more than it improved I've learned to stumble to the bathroom while mostly asleep and instead of a flood it's just some in my pad before I reach the bathroom.

It's a hard thing because clozapine does work so well and yet the side effects can be pretty frustrating. For me the incontince is at least partially because as soon as I take it I start getting really thirsty and drink water and then that makes me need to pee. I wake through the night to drink and pee and if I could just not do that it would be better. But it is what it is.

I wish I had some kind of advice but I don't. Just my experiences.
