tuberculosis
A doctor examining chest X-rays of patients infected with tuberculosis, which remains one of the world's deadliest diseases.
During the initial two-month phase of treatment for tuberculosis, patients undergo a combination therapy consisting of four specific drugs: isoniazid, rifampicin (rifampin), ethambutol, and pyrazinamide.1
This multi-drug approach is essential to prevent the development of drug-resistant bacilli. While this initial phase typically renders the patient noninfectious relatively quickly, it must be followed by a continuous treatment period of four to nine months to ensure a complete cure.1
