I Had Gastric Bypass On July 29th Still Taking Prilosec

I had gastric bypass on July 29th still taking Prilosec 40 mg a day, Calcium chew, Multivitamin, B12, and as needed Zofran 4mg for some residual nausea; and I am a chronic pain sufferer with DJD, osteoarthritis, and Fibromyalgia.
I was just prescribed Voltaren XR 75mg and Tizanidine 2mg both to be taken twice a day by primary care for severe inflammation pain. Can't speak with anyone today are these drugs okay to start?
I see my Bariatric for 2 Mos. F/
U on 9/28/16 with fasting blood work.
