Asmec and cephalexin can be taken together. Asmec is a cough suppressant and wheezing medicine, which is suitable for the treatment of wheezing bronchitis and bronchial asthma, and is also effective for cough and wheezing caused by other respiratory diseases, such as acute bronchitis and pneumonia. The main ingredients of Asmec are methoxynamine hydrochloride, aminophylline, chlorpheniramine maleate and noscapine, so Asmec cannot be used in combination with other cough suppressants, anti-cold medicines and antihistamines. Cephalosporin is an antibacterial agent and can be used in combination with Asmec. Cephalosporin is a broad-spectrum antibiotic that mainly targets most cocci and some bacilli. If you take cephalosporin, you must clarify whether it is a bacterial infection, because if it is a mycoplasma infection or a viral infection, taking cephalosporin has no effect.
