Concerns about Seroquel and Ditropan Interaction

Is anyone taking both seroquel and ditropan? I decided to try stopping medication in January this year and ended up going down bad with depression and anxiety about a month and a half later, with new symptom of feeling like I need to pee constantly when awake. I've spoken to a urologist who recommended Ditropan if after 8 or so weeks back on medication it didn't settle. I decided to try ditropan as fed up with feeling restricted to home even more so than having anxiety anyway. I noticed tonight that seroquel (quetiapine) is listed as one not to mix with ditropan and got a bit worried...
