A word of caution. After reading these responses I started NAC 600 mg one tablet in the am. After taking it the next morning I developed the worse headache I have ever had. Ended up in the ER and 7 days later still have a frontal pressure headache. To have an MRI of my brain tomorrow. Would encourage others to check with their providers first before taking any supplements. They are not regulated and studies show some have had dangerous chemicals in them.

Hi @mecfs, I’m so sorry to hear about your reaction to NAC! It’s frightening to have that experience after only one dose. I hope the side effect is only temporary. It’s possible that your reaction was coincidental to the taking of the NAC and not caused by it drug, but either way, I really hope you get to the bottom of this headache and pressure!

Thank you for sharing this cautionary advice with the forum. It’s important to note that supplements aren’t regulated by the FDA and can pose health risks…and to always check with health providers before taking them!

Wishing you a clean MRI tomorrow. 🙃 Keep us posted, ok?

I want to thank you for that PSA that you sent it's a great word of wisdom I myself over the course of just the past 6 weeks have had them write prescriptions and rewrite prescriptions because they will prescribe something and I will do my research when I get home and if it's something that gives me concern I'm not going to take it and I would not be taking something that someone else had told me to use if the doctors don't feel safe. So nice of you I really am praying for you for your test tomorrow may God heal you quickly

Hi. I just came across your post today. I haven't been seeing all posts in the thread for some reason. I just wanted you to know I wasn't ignoring your post. I hope you get well soon.

Thank you for sharing this caution. I too have learned that supplements can have dangerous side effects.
