I've recently been given mucodyne by my consultant approx 3 weeks ago. Since then my cough seems to have got worse to the point where I'm now coughing so much I'm hanging over the sink retching. I've noticed that the mucus I bring up is lighter in colour than it was but to get it up I seem to have to cough really hard and sometimes feel like I seriously can't breathe. Anyone else on mucodyne had these problems? I expected to find it easier to get the mucus up not harder! Wondering whether to stop taking them?
