Meds for radicular symptoms

Hi! I work in an orthopedic urgent care. My supervising physician has decided that he wants the APPs (who work independently in the urgent care) to use a specific treatment plan for radiculopathy consisting of celebrex, Medrol, gabapentin/pregabalin, and duloxetine.

When I started this job (less than a year ago), I had heard some of the APPs treat persistent/chronic radicular symptoms this way. Now we are being told to treat all patients “the way he would” which includes the above medications for 4-6 weeks.

I’ll also add when I started that some of the PAs that have been there years (like 5-8 years) did not know that some of these meds should be titrated up and weaned off…

My main concerns are that this feels out of scope (my SP does not specialize in spine or pain management) and we’re an urgent care, lack of follow-up for medication management, delay in pertinent imaging and/or referral for long term management/definitive treatment, and potential inappropriate use of medications (in this setting).

Has anyone else encountered this situation where your SP wants you to treat a patient a way you don’t agree with, and if so, how did you handle it?

Secondly, does anyone have experience with prescribing this combination of medications for acute radicular symptoms? And if you do, what setting are you in and how do you manage these medications?
