About 1 hour after taking Ambroxol, the sputum will become diluted and easy to pass out, and generally, sputum can be passed out after 1 day; however, Ambroxol is metabolized more slowly in some patients, so they may need to wait for 2~3 days before they start to pass out the sputum.
It should be noted that Ambroxol may cause side effects such as vomiting and diarrhea, and is contraindicated in patients with hepatic or renal insufficiency, and is contraindicated in pregnant women less than three months of gestation.
