I take generic Mucinex everyday and do Pulmozyme. Pulmozyme SHOULD be enough to thin mucus, but as we all know, it doesn't always work as it SHOULD. The way I see it, every little bit helps. Even if Mucinex isn't available in Canada, they may have a generic. The active ingredient is guaifenesin, check around for that. My dr told me, if I'm going to take guaifenesin, make sure I don't get the one that has a cough suppresant in it also, just the expectorant. The suppresant keeps you from coughing and getting anything out.
