Anti-tuberculosis drugs currently generally require 4 drugs for 1 month, isoniazid, rifapentine, pyrazinamide, ethambutol. 1 month’s dose includes 1 bottle of isoniazid, 4-5 boxes of rifapentine, 2 bottles of pyrazinamide, 1 bottle of ethambutol, the total cost of 4 drugs is generally about 300 yuan, and the total course of treatment is at least half a year, so the total cost of a half-year course of anti-tuberculosis drugs is about 2,000 yuan, and halfway through the course of treatment, you also need to The total cost of a six-month course of anti-tuberculosis drugs is therefore about 2,000 yuan, with liver-protective drugs required halfway through. If drug-related liver damage occurs, hospitalization is required to provide intensive liver-protective treatment, and anti-tuberculosis drugs can be given only after liver function is normalized. Therefore, the cost of a relatively smooth anti-tuberculosis program is about 2,000 yuan for a six-month course of treatment. If liver damage and other complications such as skin and kidney function do not occur, the cost is manageable, and if it is infectious TB, the state will give free anti-TB drug treatment.
