Why is treatment for TB 6 months?
After taking antibiotics for 2 weeks, most people are no longer infectious and feel better. However, it’s important to continue taking your medicine exactly as prescribed and to complete the whole course of antibiotics. Taking medication for 6 months is the best way to ensure the TB bacteria are killed.
Is 6 months TB treatment enough?
Few or no deaths were reported in the individual trials, and in no case did enough deaths occur for a comparison of short vs. long regimens. Reviewer’s conclusions: Longer periods of treatment (at least up to 6 months) result in higher success rates in patients with active TB, but the differences are small.
What antibiotic is TB treated with for 6 months?
Regimen Effectiveness The 4-month rifapentine-moxifloxacin TB treatment regimen is as effective as (noninferior to) the standard daily 6-month regimen in curing drug-susceptible TB disease. Must be administered completely within 70 days from treatment initiation.
How many months TB treatment should take?

How many stages of TB treatment are there?
The standard six month course of treatment consists of two phases. The first phase lasts two months and is called the intensive phase. The second phase lasts four months and is called the continuous phase.
Can tuberculosis come back after treatment?
A recurrence of TB can be due to relapse or re-infection [1]. To prevent relapse, TB treatment guidelines in the United States (U.S.) recommend extended treatment for TB cases with cavities on chest radiograph and delayed bacterial clearance from sputum [2]. Re-infection is prevented when TB transmission is averted.
What happens if you take TB medication without TB?
You have only dormant (sleeping) TB germs in your body, so they are not making you sick. You cannot pass these TB germs to others. Yet—if you don’t take medicine to kill the TB germs now, you can get sick with TB disease in the future.
Why TB treatment is so long?
A fundamental problem in the treatment of tuberculosis (TB) is the long duration of therapy required for cure. The recalcitrance of Mycobacterium tuberculosis (MTB) to eradication is thought to result from its achieving a nonreplicating (dormant) state in the host.
What is TB treatment success rate?
The WHO recommends that a good performing tuberculosis program should achieve at least 90% treatment success rate and 85% cure rate [2].
Why is TB treatment so long?
A long treatment is required because antibiotics work only when the bacteria are actively dividing, and the bacteria that cause TB can rest without growing for long periods. This treatment is necessary to keep the latent TB infection from developing into active disease.
What happens after tuberculosis treatment?
Once your course of treatment is finished, you may have tests to make sure you are clear of TB. You might need more treatment if tests show there is still TB bacteria in your body, but most people will get the all-clear. Your treatment will not be stopped until you are cured.
Which type of tuberculosis is infectious?
TB that affects the lungs (pulmonary TB) is the most contagious type, but it usually only spreads after prolonged exposure to someone with the illness. In most healthy people, the body’s natural defence against infection and illness (the immune system) kills the bacteria and there are no symptoms.
Can the TB be completely cured?
With treatment, TB can almost always be cured. A course of antibiotics will usually need to be taken for 6 months. Several different antibiotics are used because some forms of TB are resistant to certain antibiotics.
What happens after TB is cured?
At two years after treatment completion, 3.3% of patients had died and another 3.6% had to start another round of TB treatment. This is quite a high rate of fatality and could indicate that even after being microbiologically cured of TB, patients are still pretty sick.

We found no evidence to suggest that six-month treatment regimens are inadequate for treating people that have intestinal and peritoneal TB, but numbers are small.
How long should we treat abdominal tuberculosis?
Six-month therapy for people with abdominal tuberculosis. Most current guidelines recommend treating people that have abdominal TB with antituberculous treatment (ATT) for six months, but some clinicians treat for longer periods due to concerns that six months is not adequate to achieve cure and prevent relapse of the disease after the end…
What drugs are used to treat tuberculosis (TB)?
There are 10 drugs currently approved by the U.S. Food and Drug Administration (FDA) for treating TB.

Why is it important to finish treatment for tuberculosis (TB)?
It is very important that people who have TB disease are treated, finish the medicine, and take the drugs exactly as prescribed. If they stop taking the drugs too soon, they can become sick again; if they do not take the drugs correctly, the TB bacteria that are still alive may become resistant to those drugs.
