Expectamed NAC-Q 600 Effervescent 10 Tab

Expectamed NAC-Q is N-acetylcysteine 600mg in an effervescent tablet, the mucolytic that chemically snips the disulphide bonds holding mucus together, turning thick, stuck chest phlegm thin enough to cough up. NAC is a registered medicine across Europe for exactly this, with trial evidence in chronic bronchitis and COPD of fewer flare-ups and easier clearance, and the same molecule is medicine's standard antidote in paracetamol overdose, a marker of how well its chemistry is understood. The fizzy format doubles as the fluid intake that every mucolytic needs to work.

When chest mucus is too thick to shift, no amount of coughing helps; changing the mucus itself does. This is the strongest over-the-counter mucus-thinning chemistry available.
