Hi Missy,

From what I'm seeing online, there are moderate drug interactions listed between Morphine and Xanax; with the potential of it causing an increased risk for impaired thinking/judgement, dizziness, drowsiness, and an overall inability to concentrate. So if this is a concern to you I would probably wait at least double that amount of time in between doses, just to be on the safe side.

For the record, nhtsa.gov states that Morphine has a relatively short half-life of anywhere between 1 1/2 to 7 hours.

This means that if you took 15mg's, then an estimated 5 hours later (1 1/2 to 7hrs) you'd still have half of that dose (7.5mg) left working in your body. Waiting an additional 5 hours though, you'd have roughly 3.75mg left working in your body. And at this point I doubt the Morphine would be having a strong effect on you enough to cause such interactions with Xanax to begin with.

Anyone else have thoughts to share on this?
