I am struggling with Methane SIBO and Gastroparesis for a couple years now. I was on Xifaxin last year and it worked quite well and had to take it again and the results didn't last as long and the symptoms returned. I had to transfer my care locally as it's costly for me to travel to Mayo. I was then prescribed by my local GI doctor, the Antibiotic Neomycin in combination with Flagyl. I was on a daily dose of 6000mg Neomycin and 1500mg Flagyl. It didn't help and was wondering if anyone has been prescribed Neomycin and at what dose? I ask because I suffered hearing loss and nerve damage from being on a high dose for over 10 days. I also developed an insanely loud noise in my ears called Tinnitus. I was told I have Neurotoxicity. No one can help that from what I've been told. I was in the ER 2x from complications and have seen maybe 6 specialists. Has anyone ever tried Neomycin or anyone have knowledge on dosage? I called my Mayo Doctor and he said they don't even use Neomycin. The other doctors I saw were shocked by the dosage and everyone referred me to Mayo for help but Mayo has told me they can't help further and I have to "live" with it. I'm desperate for anyone who can help! Thank you.
