My pulmonologist prescribed dexpak 13 day. The reviews are scaring me. I took 3 1.5 before breakfast today. I have pulmonary fibrosis caused by pnumonia in 2010. 25%of lungs damaged. Have done very well. Rarely needed oxygen until lately. Short of breath. Any help or advice about this drug? Thank you. I am 62, female with history of depression, anxiety, problems sleeping
