The main anti-tuberculosis drugs include isoniazid, rifampin, ethambutol, and pyrazinamide. Isoniazid is an effective bactericidal agent with better efficacy and less toxicity, and is the drug of choice for tuberculosis treatment, with peripheral neuritis as a common adverse effect. Rifampin is a broad-spectrum bactericidal agent, and the most common adverse effects are gastrointestinal irritation as well as hepatic impairment. Ethambutol has fewer side effects. The most common adverse effect is damage to the optic nerve, but this is also one of the most serious adverse effects. Visual fatigue and loss of vision may occur during the course of the drug, so vision needs to be monitored during administration. Pyrazinamide is also an important drug for anti-tuberculosis treatment, and its side effects include increased uric acid and joint pain. If there is an increase in uric acid, you need to drink more water, review regularly, and eat less soy products, animal offal, seafood, and beer.
