The good news is that tuberculosis is both curable and preventable! The treatment for TB involves the combination of at least three TB medications, as any fewer can result in drug-resistant TB. Patients are typically required to continue taking TB medications for at least six months. The medications that have the greatest activity and effectiveness against TB bacteria, known as the “First Line” drugs, are as follows: • Ethambutol • Isoniazid • Pyrazinamide • Rifampicin With that being said, there are more than twenty available drugs for tuberculosis treatment. As such, the types of TB medications used in treatment vary according to the patient’s circumstances.
