5 mg bystolic, (nebivolol) 7.5 mg hydrocodone x 2/day, uta capsule x 3/day. are these considered high doses that could cause cns depression?

Minimal: Not sure what you are referring to as uta. Bystolic (nebivolol) is a BP medication. Hydrocodone does have some CNS depression. That is not that high of a dose, but is not a medication you should be taking on a regular basis long term.

All opioids can : Cause respiratory depression. I don't know what bystolis is and I am assuming uta is ultram? If so these aren't particularly high doses, but each patient is different and can have variable responses to medications and their side effects.
