After two months of intensive treatment for tuberculosis, it is still necessary to continue to complete the consolidation period of treatment, otherwise there will be a possibility of recurrence of tuberculosis. In addition, whether the intensive period of tuberculosis treatment is only two months or needs to be extended depends on whether the sputum smear is negative or not at the end of two months, and the medication should not be stopped blindly during the treatment period. The usual treatment regimen for TB is a two-month intensive period with isoniazid, rifampicin, pyrazinamide and ethambutol, and a consolidation period of at least four months with isoniazid and rifampicin. Generally, after two months of treatment in the intensive phase, a sputum smear is required, and if the sputum smear is negative, the treatment can be entered into the consolidation phase; if the sputum smear is positive, the treatment in the intensive phase needs to be extended. If the sputum smear is negative after one month of extension of the intensive phase of treatment, the patient can enter the consolidation phase of treatment. After entering the consolidation phase, you still need to take the medication regularly, otherwise there may be a recurrence of TB. If you are diagnosed with tuberculosis, please follow the doctor’s instructions and do not stop taking the medicine.
