I have been on Celebrex for over 2 yrs. it does a wonderful job, but is is quite expensive ($121 for a 90 day supply). I have an appt with my family MD for refil of prescriptions. I m considering asking if I can try generic Mobic. I understand it is an NSAID with an increase risk of GI problems. I also take Lisinopril, HCTZ, ASA 81mg every day, and Ditropan 1mg qod. I ve never had GI problems until I started taking Ditropan. With my doctors approval, I changed my dose to of Ditropan from qd to qod which has greatly reduced the indigestion the qd dose caused. Your opinion re trying Mobic rather than Celebrex?
