Took NAC today

Posted by maliko @maliko, Dec 1, 2024

I bought a bottle of Jarrow's sustain 600mg NAC (N-Acetyl Cysteine) supplement. I took one tablet this morning and within 15 minutes, I started feeling really flushed and got extremely sleepy, tired, and dizzy. It lasted about 3 hours and slowly subsided. I did not notice any improvement in my cough or throat clearing. Has anyone experienced this when they took NAC for the first time? Will my body adjust to it? Thank you

I was on it for 14 months and it did the trick along with Azith and ethambutol. Over several months I got a nice tan. Thats it. I think a lit depends on your natural skin tone. I have very light skin with freckles. Everybody is different and reacts different. I was extremely stressed about it prior to starting clofazimine and it turned out I didnt need to be.

Thank you so much. I hope it works for me. I am doing amikaycin infusion along with that one and two others

Exercise caution when considering this supplement. I took 600 mg daily for four days, and on the fourth day, I ended up in the emergency room, fearing I was having a heart attack. I experienced excruciating chest and arm pain, dangerously low blood pressure (74/46), cold sweats, and nausea. I called 911 and was rushed to the ER, where all tests ultimately came back negative for a heart attack. After conducting some thorough research, I identified the cause as a severe reaction to NAC. Investigate the symptoms I encountered, and you'll understand the potential dangers associated with this supplement.

@sixtz4me Wow - that's scary. Your experience just reinforces the importance of realizing SUPPLEMENTS ARE MEDICATION and carry risks as well as potential benefits. The big down-side is that they are not strictly regulated, so one must not only consider side effects and interactions, but whether the supplement contains what the label says, in the correct quantity, and nothing not on the label.
