Pseduo doesn't go away. I'm not sure why docs put people on antibiotics (more so on older patients), when they are not symptomatic. Pseudo will not go away. Cipro is usually done at the beginning of treatment. 2 weeks of Cipro while doing either 2weeks of 1 month of Tobra, and then 2 weeks or 1 month off of Tobra. If docs prescribed meds for PSeudo even if you were symptomatic, then you would be on meds 24/7 and eventually begin to build a resistance to antibiotics. Thats why I don't take a lot of meds - resistance. What will you do 10 years from now, when you're resistant to Cipro and Tobra?
