My brother started taking linezolid originally after a kidney surgery in which three m ass' or masses were removed and had a pocket of abscess with a lesion .He was then given linezolid through IV for an entire week in the hospital then sent home with 60, 600 mg tablets he began having hallucinations, Delirious thinking ,no appetite, vomiting ,diarrhea ,shortness of breath, heaviness in the chest and chest pains. We have continued to tell the doctors that he had'nt any of these effects until taking the medicine. hHe stopped taking the medicine 2 days ago and was being treated for fluid around his lungs can someone please give me some advice he is now in ICU and his future is uncertain.
