It's been so long since I've posted but I always direct other CF friends to read the information on here.

I just turned 40 years old- yay!

My question: do glutathione levels definitely get depleted with strong antibiotic use?

My FEV1 recently dropped by 10% (while on IVs). I haven't seen this number (84%) since I enjoyed the 13% boost GSH gave me when I was 27 years old. I have been on IVs for 8 weeks due to MRSA found in my sinus culture. I believe that is all cleaned out (I had sinus surgery too), but was shocked at my FEV1.

I am planning on starting the dosage I took years ago once again, but was wondering of this experience has happened to anyone else. I've been able to maintain in the 90's for years with a low dose (at best) of oral and inhaled GSH.

I hope everyone is well!
