The most important way to stop spreading TB is to take all your medicines correctly. You need to do a sputum test at various time points of your treatment. This test will show whether the treatment is effective.
You can further lessen the risk of spreading the infection by:

• covering your mouth when you cough. Use of a simple mask by the patient can reduce transmission of the germs.
• staying in a room with good ventilation. TB spreads in closed spaces where air doesn’t move.

Remember, TB is spread through the air. People cannot get infected with TB bacteria through handshakes, sitting on toilet seats, or sharing plates and utensils with someone who has TB.

TB bacteria die very slowly. It takes at least six months to kill all the TB bacteria. People start feeling well after only a few weeks of treatment. But TB bacteria are still alive in the body. You must continue to take your medicine until all the TB bacteria are dead, even though you may feel better and have no more symptoms of TB disease.

If you do not continue taking your medicine after you feel better or are not regular, TB bacteria will grow again and you will become sick again because the bacteria may become resistant to the drugs you are taking. When this happens you may need different drugs to kill the TB bacteria if the old drugs no longer work. These new drugs must be taken for a longer time and usually have more serious side-effects.
If you become infectious again, you could spread TB bacteria to your family, friends, or anyone else who spends time with you. It is very important to take your medicine the way your doctor or nurse tells you.

Very few people develop side-effects to TB drugs. Minor side-effects include vomiting, nausea, loss of appetite, joint pain, orange/red urine, or skin rash, which can be managed using simple medicines or adjusting the dosages of the drugs.
Major side-effects include deafness and dizziness (streptomycin); jaundice, vomiting (mainly rifampicin and isoniazid); visual impairment (ethambutol), shock, purpura, or acute renal failure (rifampicin).

These side-effects need to be managed by a trained physician and may require hospitalization.

Treatment completion is determined by the number of doses ingested over a given period of time. Although basic TB regimens are broadly applicable, there are modifications that should be made under special circumstances (such as people with HIV infection, drug resistance, pregnancy, or treatment of children).

The first-line anti-TB agents that form the core of treatment regimens include:

• isoniazid (INH)
• rifampin (RIF)
• ethambutol (EMB)
• pyrazinamide (PZA)

Regimens for treating TB disease have an initial phase of 2 months, followed by a choice of several options for the continuation phase of either 4 or 7 months (total of 6 to 9 months for treatment).
It is very important that people who have TB disease finish the medicine, taking 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. TB that is resistant to drugs is harder and more expensive to treat.

The only way to cure active TB is take all of your medicine for at least six months. TB germs take a long time to die. Even if you feel better after a few weeks, continue taking your medicine. If you do not, you will stop feeling better.

Usually, after a week or more of taking effective medication, most patients with active TB disease will stop spreading germs. A doctor will test the patient and then decide when the patient is no longer contagious. Most TB patients live at home and can continue their normal activities as long as they are taking the TB medicine.

Yes. Active TB disease can be cured with medicine. If you have active TB, you must take your medicine for at least 6 months.

best for you. Treatment for LTBI generally lasts for 9 months. It is important that you finish the treatment.
The most common drug used for the treatment of LTBI is a medicine called isoniazid, or INH. Most people can take INH without problems. Make sure that you tell your health care worker about any health problems that you have or any medicines that you are taking. Children and adults who can’t swallow pills can get INH in liquid form.

Yes. If you have latent TB, you cannot spread TB to other people. You can work and go to school and do your normal routine. You cannot spread TB to others.
