Hye doctor whenever I take paracetamol and diclofenac and an antibiotic ciprofloxacin 250 I got red spot in my full body and reaction on my face it swells nd after getting cetirizine it got normal but I feel extremely weak unable to get up from bed. My doctor said there is no solution of this but I really want to get some permanent solution bcz in future there will b many situations when I have to take medicine so he said I have to change my blood thus is impossible nd risky too please provide me solution.
