There were rashes on my wife's body so doctor removed ETB and PZA For 15 days  which means for 15 days my wife was on only ATK2 i.e Rcinex 300/600 After 15 days doctor introduced LEVOFLOXACIN and Linezolid So from 10 th Feb she is on below 4 medicines 1. Ricnex 300/600 ( from last 5 months) 2. LEVOFLOXACIN ( from last 1 month 10 days) 3.
