HI Thank for choosing HCM for help. Your queries and concern will be given importance, if this is the pulmonary Tuberculosis then you will have to complete the course of it. As long as the allergies are concern it may not be the sensitivity of drug and it is important to rule this out, of course the anti tb drugs may have some side effects but sensitivity is very less likely, if this is the sensitivity of the AKT then better to discuss this with doctor for another drug but to find out the causative drug is more important, you must be having allergic condition but it may not be due to AKT. It is okay if you change the timing of drugs and for that you can talk to doctor. e given information will be helpful take care.
