I am undergoing mdrtb treatment for last 19 months. I have been taking 11 pills daily . For almost 1 year in past I have been experiencing memory problems , anxiety ,fatigue , headaches , confusion etc . Last year the drug named cycloserine was stopped due to psychiatric side effects and another drug called PAS was started. Inspite of that I am experiencing the above symptoms. Can other drugs also cause such side effects .if yes will these symptoms go away after completion of treatment?
