Should MAC antibiotics continue after recovery?

Question

Hello doctor,

I hope this message finds you well.

I am 36 and have been treated for MAC lung disease for almost a year with three oral antibiotics. My latest scans and sputum tests are clear, which is good news. However, my pulmonologist wants me to continue the medication for another 12 months after these results.

The medications have caused fatigue, nausea, and stomach discomfort. I want to understand why the treatment must last so long.

Is it common to keep taking antibiotics after scans and sputum tests improve?
What are the chances the disease could return if I stop treatment earlier than advised?
I am also worried about possible long-term side effects from taking antibiotics for so long, especially hearing loss and liver problems. Could this treatment cause any lasting damage?

Please help.

Hi,

Welcome to icliniq.com

I read your query and understand your concern.

Thank you for sharing your concerns. With Mycobacterium avium complex lung disease, it is common for treatment to continue even after scans and sputum tests start to look better. This is mainly because MAC infections can come back if treatment stops too soon, especially for people with existing lung problems.

Usually, doctors recommend continuing treatment for about 12 months after sputum cultures stay negative. Although this can feel long and tiring, it helps lower the chance of the infection coming back. If treatment stops too early, the infection can return, and treating it again may be harder than the first time.

Nausea, stomach discomfort, and fatigue are common side effects of these medicines. Sometimes, changing when you take your doses or taking some medicines with food, as advised by your doctor, can help you feel better. If the side effects are hard to handle, your doctor might adjust your treatment plan.

In regards to your concerns regarding long-term issues, these medications may have an impact on the liver. That is why it is advised to conduct routine liver examinations during treatment. The likelihood of permanent liver injury is low when any issues are identified early and monitored closely. Medicines such as Amikacin are more likely to cause hearing problems than standard oral antibiotics to do so. An additional hearing evaluation may be recommended by your physician if you have received amikacin via injection or inhalation.

It is great to see your scans and sputum results improving. One of the hardest parts of MAC (Mycobacterium avium complex) treatment is not just getting better at first, but also making sure you stay healthy and avoid the infection coming back after treatment ends.

I hope this addresses your concerns.

Please feel free to follow up if you need any additional clarification.

Wishing you the very best in your recovery.

Thank you.
