Hi Doctor, My mother has been diagonised with arthritis and she has been give the following tablets by different doctors- Zerodol, Fenpar, Cartil-Forte, Zedcal, Fexet, Cetefact, Freeflex Forte, Ferizest, Lozart-H, Recartix-Forte, Caltas-5, Pirixicam over the last 1 year. More than 5 times she has had her face/mouth/tongue swollen. Could this be due to the side effects of this drugs? and if so what is best suitable for her as she has high blood pressure and is aged 70?
