Hi<br>We're fairly new to nebulised antibios, our daughter having done only one 6 month session with Gentamiacin. We read somewhere that nebulisers should be replaced from time to time - we even read somewhere that the whole machine should be replaced after each course (ie. in this case, 6 months). I know many of you have lots more experience than we do here - can you possibly advise??<br>Thanks!<br>
