Mixing Medications For Emergency Treatments

I've been working in psych for almost 2 years. I've been putting haldol, benadryl and ativan in the same syringe for the entire time I've been working this specialty. I remember asking about this when I first started and told you can. I've never seen it precipitate so I've never thought twice about it.

Tonight, a coworker - with whom I've been working the entire time - gave benadryl separate and said she read something back in the mid '90s about not mixing these two drugs. (First, I'm kinda annoyed that I've been working with her over a year, she's seen me mix them and never said anything, but that's besides the point).

Does anyone else mix these in the same syringe and had precipitate or negative outcomes?

I agree with the above post. I always have mixed the haldol w/the ativan, and given the benadryl by itself. When I'm not sure about mixing something I always call the pharmacy.

I know this is an old blog, but we call that a B52, and we mix it all! :)

At my facility, we do combine Haldol and Ativan together and give Benadryl by itself.
