The subject of this topic does not surprise me. I support what Sarajerome states, listen to your body and recognise the signs of an exacerbation that may only need an increased course of oral A/Bs, not IV drugs.
For many years I have started a combo/course of oral A/Bs that I know have the ability to 'save' a trip to hospital, where I am at real risk of picking up other 'nasties'. Within a few days if there are signs of more productive, virulent sputum, then hosp. is often necessary. I also increase my H/S and nasal rinse treatments when I feel there is a threat on the horizon.
While I feel I can make my own judgement call, [I'm 60], younger patients and children may not be able to.
Cheers
Eileen.
