Crippling side effects of medication

i viewed a documentary on the crippling side effects of the antibiotic Cipro .A woman with UTI was prescribed and after 3 tablets,she was left crippled as the side effect.A medical intern also suffered the same condition and had to be a wheelchair user but his medical background led him to seek stem cell therapy which helped him recover his mobility. There is so much hype on evidence based medicine but as the opoid crisis in the US shows when painkillers become addictive to the drugs user,what is the effect but increasing dependence on drugs to live a pain free life. thats the dilemma of modern medicine,there is no perfect solution.
