I have back pain all over my back and shoulders is it ok to take flexeral i am currently taking many meds zoloft (sertraline) 200 mg klonopin .25mg and trazadone?

Over sedation: Flexeril (cyclobenzaprine hcl) works as a muscle relaxer mainly by sedation, when other sedating medications are taken as well there can be unpredictable results. More sedation but no more muscle relief. So generally we avoid those combos.

Caution.: Yes, but do take it when you're at home because it causes drowsiness and the three medications you are on are also sedating especially trazodone and klonopin (clonazepam). I caution you especially about driving or operating heavy machineries.
