Ambroxol tablets are sputum thinners used in bronchitis, pneumonia, bronchiectasis, including also bronchial asthma, where sputum is not easily coughed up because it is thicker. Generally, the dose for adults is 1-2 tablets 3 times a day, taken orally after meals. For children, the dosage should be reduced according to the child’s condition and their own weight and surface area, while pregnant and lactating women should use with caution. This drug should be used in combination with certain antibiotics, such as amoxicillin, cefuroxime, erythromycin and doxycycline. The simultaneous administration of these antibiotics may increase the concentration of these antibiotics in the lung tissue, which may aggravate the side effects of the drug, so the combination can be avoided. If you have no choice but to combine them, reduce the dose of the drugs as appropriate.
