Bronchiectasis and azithromycin 3 times a week.

Posted by rma1949 @rma1949, Dec 31, 2025

Is anyone trying azithromycin 3 times a week to try to stop recurring exacerbations of bronchiectasis from happening as often? My pulmonary doctor has suggested this. I’m a little leery because I don’t want to develop bacterial resistance from overuse. I currently use 14 days of amoxicillin when I have a bronchiectasis exacerbation.

Interested in more discussions like this? Go to the MAC & Bronchiectasis Support Group.

Just wondering if you have tried the new drug Brinsupri that is supposed to reduce Bronchiectasis flares ? I would be interested to know what your NJH doc thinks about the lower dose Azithromycin and resistance.

I started Brinsupri on 9/21 and will be stopping. It has not helped me. Neither has Ohtuvavre or Dupixent.

@tomdeleo The literature says full benefit sometimes not achieved until 6 months.

@cwal Unfortunately, I have a Medicare advantage health plan and it does not cover Brinsupri. I was misled by my insurance broker and now it's too later to change to the original Medicare plus a gap-at least according to my new health insurance broker. I also cannot get Nuzyra (can't afford the $30,000/month), despite the fact that it shows to be highly effective on MABC.

I will post it when I learn more. I did recently read that Erythromycin is the recommended macrolide for BE inflammation, and it does not cause resistance to MAC, not sure about MABC.

I also have a Medicare Advantage plan and between the insurance and The Assistance Fund I pay nothing -so far. Who knows what will happen in the future due to the craziness going on with health care plans. Have you heard about The Assistance Fund? Many have been able to get the medication this way.

I was diagnosed with bronchiectasis in 2023 and was on antibiotic IV and pills,it seems, every other month. This past October 2025, I was placed on 500mg daily azithromycin to fight off pseudomonas and have not had any flare-ups since then. I started brinsupri 2 weeks ago; Have not felt any differently with brinsupri since being on azithromycin. Now My mucus buildup is minimal; even after lung clearing 2x daily with 7% saline whereas prior to AZ daily, I was spitting up mucus throughout the day. I will also ask my MD about resistance, Only drawback with AZ daily, unfortunately for me, I seem to be the 1-10% with the side effect of joint and muscle pain.

@cwal Yes, I have heard of it, but I don't know much about it. Where did you apply? I may not qualify as I heard the income requirements are very low. That said, I certainly don't have anywhere nears the income to ever pay for these drugs.

@rma1949 I've cut and paste from the article "Bronchiectasis — A Clinical Review" from 2022 (from the ABCs of bronchiectasis thread) which describes the use of azithromycin. It can be quite beneficial in those with frequent exacerbations. When I was on it for bronchiectasis I noticed auditory side effects but it's difficult to pin this on that experience as I have been on my share of z-paks in my life. So might have been a cumulative effect.

"For patients with substantial daily symptoms and frequent exacerbations (three or more per year), additional therapies may be required to improve quality of life and prevent further lung damage. In a meta-analysis of three randomized trials, investigators found that the use of macrolide antibiotics reduced the frequency of exacerbations and increased the time until the next exacerbation. Improvements in quality of life were also documented in those trials. The mechanism of action is unclear, although macrolides may inhibit quorum sensing by P. aeruginosa. The usual dosing regimen is azithromycin at a dose of 500 mg three times per week or 250 mg daily. Although the studies were conducted for only 1 year, it seems that macrolides are generally safe and have an acceptable side-effect profile over longer durations. However, caution must be observed when prescribing macrolides, given the risk of resistance and gastrointestinal, cardiac, and auditory side effects. Macrolide monotherapy should not be used when nontuberculous mycobacterial infection is present or has not yet been ruled out."

@scoop Thanks, Scoop, for this. That last sentence seems key and explains the use of ethambutol and rifampin along with the azithromycin. Have a happy and healthy New Year!
