TB drugs for the elderly are usually taken for six months to two years, but the time of stopping the drugs is not fixed, depending on the severity of the patient’s condition and the type of tuberculosis. If the elderly tuberculosis is the early stage of the disease, then the symptoms may be mild, so the treatment is shorter, may take about six months to stop as prescribed by the doctor. If the disease is more serious, or if it is recurrent TB, then the elderly TB drug may need to be taken for about 1-1.5 years before it can be stopped. In drug-resistant TB, the drug may need to be used for about 2 years before it can be stopped, so the timing of stopping the drug depends on the specific situation. When using a combination of drugs in older adults, regular checkups are usually needed to help observe the control of the disease, the patient’s physical recovery, and the side effects of the drugs, which, combined with the results of the checkups, may lead to adjustments in the duration of the drug. During the period of combined drug treatment of tuberculosis in the elderly, it is recommended to follow the doctor’s instructions for regular checkups, but also to do a good job in life care.
