Diagnosed with lymphadenitis tuberculosis (armpit ) on 2nd march 2017 , my weight is 61kg ..I was having rcinex 450, pyrazinamide 1500, ethambutol 800 for 2months 10 days ..now i was told by other physician that i was underdose as per my weight  and I should switch to Rcinex 600 and ethambutol 1200mg .. my lump has reduced from 3.7×3.5×1.2 to 2.7×1.5×0.9 cm .. so now i am switching to new potency of Rcinex ..so technically i was underdose for 2 months will that create  resistance to drugs ???
