How is it treated?
Doctors generally use a combination of four antibiotics to treat active TB, whether it occurs in the lungs or elsewhere. Medications for active TB must be taken for at least 6 months. Almost all people who take their medications as directed are cured. If tests continue to show an active TB infection, treatment is extended for 8 to 9 months.
One antibiotic taken for 9 months is the usual treatment for latent TB. This prevents the infection from becoming active and reduces the risk of complications.
If you miss doses of medication or you stop treatment too soon, your treatment may go on longer or you may have to start over. This can also cause the infection to get worse or lead to antibiotic-resistant infections that are much harder to treat.
A health professional may have to watch you take your medications. This may mean daily visits to a doctor's office or public health facility. Or the health professional may come to your home or workplace. A cure for TB requires you to take all doses of the antibiotics. Direct observational treatment ensures that people follow medication instructions, which is helpful because of the long treatment course for TB. Cure rates for TB have greatly improved because of this treatment practice.
If active TB is not treated, it can damage the lungs or other organs and can possibly cause death.
