Hi i undergo pcnl last saturday, i was discharged last tuesday. My doctor prescribed me with ciprofloxacin since there is still stent on my left kidney (pcnl due to multiple staghorn calculi and will undergo shockwave after i recover from the recent operation). Now, my problem is, i have been suffering from too much rashes, somehow it has blisters.. I consult a derma yesterday and she gave me prenisone twice a day and aerius, her initial findings is that my body react to arcoxia 120 mg, the medicine they gave in the hospital after operation and which i took it 3 times once a day for 3 days.. Can i take prednisone twice aday, aerius once a day, ciprofloxacin twice a day and iterax once a day without allergic reaction? Thanks
