The therapeutic measures that need to be taken when black phlegm is present depend largely on its cause. More commonly, it is due to inhalation of large quantities of dust due to varying degrees of pollution of the air in the surrounding living environment, so it is important to stay away from these possible sources of pollution. As much as possible, stay in a well-ventilated environment with relatively fresh air, few people and no pollution. It is also seen in some cases of inflammation of the respiratory system, due to viral, bacterial or Mycobacterium tuberculosis infections, where there are old bleeding lesions. At this time, anti-inflammatory treatment, such as for bacteria can choose antibiotics, such as penicillin, amoxicillin, clindamycin and so on. For Mycobacterium tuberculosis, you can choose a combination of anti-tuberculosis drugs, such as isoniazid, rifampicin, ethambutol, pyrazinamide, streptomycin and so on. Follow up at any time to adjust the treatment program.
