So, how long is the shelf life of ambroxol oral liquid? How many days can I eat in Kaifeng? Ambroxol oral liquid is a compound preparation, and each milliliter contains ambroxol hydrochloride 1.5 mg and clenbuterol hydrochloride 1 microgram. It can be used for treating cough, sticky phlegm, difficulty in expectoration and wheezing caused by acute and chronic respiratory diseases (such as acute and chronic bronchitis, bronchial asthma and emphysema). Ambroxol oral liquid should be taken in accordance with the usage and dosage specified in the instructions. Long-term excessive use can cause arrhythmia or cardiac paralysis, which requires special attention. The symptoms of long-term overdose generally disappear after stopping the drug. The antidote for overdose is cardiac selective beta blockers, but patients with bronchospasm should use it with caution. The shelf life of ambroxol oral liquid is 2 years. During the retention period, Beijing Hanmei Pharmaceutical Co., Ltd., the manufacturer of ambroxol oral liquid, will be responsible for its quality, and patients and friends can rest assured to take it. However, the opened ambroxol oral liquid is easy to deteriorate due to the influence of the environment, so it is not suitable for long-term storage after opening, and there is no relevant information about the specific number of days after opening. If you need to buy ambroxol oral liquid, you can buy it at Kang 'aiduo drugstore. Recommended reading: Is Ambroxol Oral Liquid the same as Ambroxol Hydrochloride Oral Liquid?
