Discharge Instructions for Tuberculosis (TB)

You have been diagnosed with tuberculosis (TB), a serious disease caused by a type of bacteria. It is spread from person to person through the air, mainly from people who have the infection in their lungs or throat. TB may cause disease in any part of the body. But it is most common in the lungs, lymph glands, spine, kidneys, or brain.

Not everyone with TB gets sick. There are 2 types of TB:

  • TB disease (infectious TB). People with TB disease often feel sick and are infectious. This means they can spread TB bacteria to others, depending on where in the body the TB bacteria is.

  • Latent TB infection. People with this TB have no symptoms, don't feel sick, and can't spread TB bacteria to others. Some people with latent TB, especially those with a weak immune system, can develop TB disease. But many people with latent TB never develop TB disease. However, without treatment, latent TB can progress to TB disease.

Here’s what you can do to take care of yourself and to prevent the spread of TB.

Prevent the spread of TB

If you have TB disease, TB bacteria are multiplying in your body. Your immune system can't stop the bacteria from growing. You can spread TB bacteria to others when you have TB disease in the lungs or throat. TB in other parts of the body, such as the kidneys or spine, often can't be spread. If your healthcare provider tells you that you have TB that can be spread (TB disease) or you have latent TB and are at risk for TB disease, you will be prescribed 1 or more medicines. You will need to take medicine for a few months. Your provider will tell you when you can stop taking the medicine.

If you have TB disease (infectious TB), follow these tips to prevent the spread of TB bacteria to others:

  • Stay home. Don't go to work or to school until your healthcare provider says you can go back. Don't have close contact with anyone until your healthcare provider says it's OK.

  • Make sure that your family, friends, and coworkers or classmates are tested.

  • Keep your hands clean. Wash them if you use them to cover your mouth when you cough.

  • When you cough or sneeze, take steps to prevent the spread of TB:

    • Cover your mouth and nose with a tissue.

    • Put your used tissue in a closed bag and throw it away.

    • If you don't have a tissue, cough or sneeze into your upper sleeve or elbow, not your hands.

    • Wash your hands often with soap and clean, warm or cold water for at least 20 seconds. If soap and water are not available, use an alcohol-based hand gel.

Important care advice

  • Take your medicine exactly as directed. Keep taking it even if you start to feel better. You will take medicine for several months and maybe longer. This will depend on your type of TB. Not taking your medicine for the full course may lead you to get sick again. It also increases the chance of drug-resistant TB. Drug-resistant TB means that 1 or more of the typical medicines for TB don’t work.

  • Follow your healthcare provider's direction about when it's OK to be in close contact with others.

  • If you are taking birth control pills, ask your healthcare provider if there are interactions with the TB medicine that could make the birth control less effective. Ask if you should use an additional backup method of birth control.

  • Check with your healthcare provider before taking any over-the-counter medicines.

  • Limit your activity so you don't get too tired. Plan frequent rest periods.

  • Keep your healthcare appointments. You will need to be checked regularly for several months to a year. This is to make sure you are not having side effects from the medicines. And to be sure your TB is responding to treatment. If you miss an appointment, reschedule as soon as possible.

  • You may be asked or required to have a healthcare worker watch you taking the TB medicines. This is called directly observed therapy (DOT). This may happen anywhere from 1 time per week to up to 3 to 6 times per week. If you are receiving DOT, go to every session.
