Is the cough medicine Gancao tablet dependent?

Compound licorice tablets and compound licorice buccal tablets are also commonly used drugs for relieving cough and resolving phlegm. Compound licorice medicine and Jilin Ganhe tea, the source of Chinese patent medicine, contain caffeine and theophylline, both of which are excitatory drugs. Excessive use is very addictive.

Proper use of caffeine can eliminate fatigue and excite nerves, and it is mainly used to treat neurasthenia and coma resuscitation in clinic. However, large doses or long-term use will cause harm to human body. "Because it is addictive, once it is stopped, there will be various withdrawal symptoms such as mental exhaustion, fatigue and weakness."

Although the addiction of caffeine is weak and the withdrawal symptoms are not very serious, the tolerance caused by long-term use of this kind of drugs will lead to the continuous increase of dosage. After reaching a certain amount, caffeine will not only act on the cerebral cortex, but also directly excite the medulla oblongata, causing paroxysmal convulsions and skeletal tremor, damaging important internal organs such as liver, stomach and kidney, inducing respiratory tract inflammation, breast adenoma and other diseases, and even leading to mental retardation and limb deformity of the next generation of users. It is reported that drugs containing caffeine have been included in the scope of psychotropic drugs controlled by the state.
