First-line drugs are generally preferred for the treatment of TB, but other drugs may be used if there are certain reasons, such as intolerance or allergy to the drug. The treatment of TB emphasizes early, regular, complete, moderate, and scientific chemotherapy and management strategies using a combination of drugs. The first-line drugs for TB include isoniazid, rifampicin, pyrazinamide and ethambutol. However, some patients are unable to receive first-line drugs for specific reasons. For example, patients with gout are unable to use pyrazinamide, which causes an increase in blood uric acid levels, at which point they need to be switched to another drug. Certain patients are allergic to isoniazid, rifampicin, etc., or have severe liver impairment, and need to be switched to other drugs. Patients with tuberculosis should follow the doctor’s instructions and use drugs in a rational and standardized way, and the prognosis is usually good and most of them can be cured. Usually the symptoms begin to subside after 2 to 3 cycles of regular drug use. If not treated scientifically, TB can spread from the lungs to other parts of the body, and even cause serious complications such as encephalitis and meningitis, which can be life-threatening. Once diagnosed with tuberculosis, it is recommended to consult a doctor as soon as possible, complete the examination, cooperate with the doctor to start scientific treatment, and follow the doctor’s instructions on the use of the above medication, do not use the medication on your own, or change or stop the medication at will.
