Talk to your doctor

Having NTM lung disease for a long period of time can cause damage to the lungs that can worsen over time. This is why, once you are diagnosed, it’s important to talk to your doctor about your plan for getting rid of the infection. This type of infection does not go away on its own and, if left untreated, can have a serious, long-term impact on your health.

There are treatment options available for NTM lung disease. You and your doctor should work together to determine if you need treatment. You may be prescribed a treatment regimen or you may be referred to a specialist who has more experience treating people with NTM lung disease.

It’s important to educate yourself and ask your doctor questions about what to expect after diagnosis.

NTM lung disease causes damage to your lungs that will only get worse with time.

The NTM Treatment Guidelines* were created by leading scientific communities to provide doctors with recommendations for the treatment of NTM lung disease. These guidelines are the globally recognized standard for the management of NTM lung disease.

Review the guidelines and speak to your doctor to find out if these guidelines could impact your treatment plan.

MAC lung disease is diagnosed

Begin treatment after NTM diagnosis

Guidelines recommend a multidrug regimen of at least 3 antibiotics

Guidelines suggest starting treatment rather than waiting for certain diagnosed patients, especially those who have:

  • a more severe infection
  • a compromised immune system
  • symptoms such as severe fatigue or other signs of decreased quality of life
  • cavitary disease

Months 1 to 5 after starting treatment

Regular sputum testing is recommended

Get sputum tested every 1 to 2 months while on treatment

Guidelines recommend regular doctor visits and monthly sputum cultures in order to assess whether or not a patient is responding to therapy.

6 months after starting treatment

Assess treatment success at 6 months

Have you tested negative for MAC bacteria?

Guidelines recommend that doctors evaluate if the multidrug regimen is working after 6 months of treatment.

Additional guidelines recommendation

The guidelines recommend staying on treatment for a minimum of 12 months after testing negative for MAC. This is to make sure the MAC bacteria are cleared from your lungs.

Lifestyle Changes

When you’re living with a lung condition, it’s especially important to maintain a healthy lifestyle and limit your exposure to NTM bacteria. That’s because exercise and diet can affect how your body works. Remember, you can always talk to your doctor if you have any questions about your lung health.

Reducing exposure

While NTM is in the environment, you and your loved ones can follow these steps to reduce exposure to NTM bacteria:

  • Raise hot water heater temperatures to at least 130°F
  • Use well water, rather than piped-utility supply, if possible
  • Avoid long exposure to shower aerosols (shorter showers)
  • Disinfect showerhead by submerging in household bleach or vinegar for 30 minutes
  • Use showerhead with large holes to reduce mist formation
  • Drain hot water heater frequently to remove sediment
  • If you have a water filter, follow manufacturers’ instructions for changing it
  • Avoid continual use of humidifiers without cleaning them
  • Have good bathroom exhaust
  • For drinking and cooking, boiling (ie, 212°F) for 10 minutes kills NTM
  • Wear a mask, when appropriate, to avoid dust inhalation
  • Moisten garden and potting soils

Keep up your appetite

  • Eat 5 to 6 small meals a day and snack whenever you are hungry
  • When you’re hungry, have a high-protein snack like nuts
  • Calorie-boost a meal with sauces, cheese, or butter
  • Eat heartier foods first at mealtimes to avoid filling up on lower-calorie foods
  • Don’t fill up on fluids
  • Want a drink? Try milkshakes and protein drinks
  • Make it spicy if your sense of taste has faded
  • Take a walk. A 20-minute walk an hour before eating helps keep up your hunger
  • Keep a food journal. Knowing what you’re eating is key
