If the symptoms of tuberculosis have not disappeared after two months of taking medication, you should go to the hospital for regular checkups and continue to take the medication regularly after evaluating the effect.

If the results show that the therapeutic effect is poor, or even have a tendency to aggravate, the feasibility of drug sensitivity test examination, to determine whether there is drug resistance, a clear diagnosis based on the results of drug sensitivity and clinical diagnosis and treatment norms, if necessary, to adjust the drug regimen.
