The treatment period for tuberculous pleurisy is usually 6-8 months, and in some patients with more severe disease, the treatment period may be extended to more than 1 year. In the early stages of tuberculous pleurisy, usually with pleural effusion as the first symptom, patients need to undergo thoracentesis and aspiration or closed drainage of the chest cavity to drain the fluid from the chest cavity to the outside of the chest. Postoperatively, isoniazid and rifampin are applied as infusion therapy, while pyrazinamide and ethambutol are taken orally, and patients can usually be discharged from the hospital after 1 month. Patients continue oral treatment with the above drugs for 6-8 months after discharge. If the patient’s condition is more severe, his or her treatment time will be extended accordingly. During the treatment of tuberculous pleurisy, patients should not increase or decrease the dosage of drugs or stop taking them without permission, and review liver function regularly to avoid damage to liver function from anti-tuberculosis drugs.
