At present, it is allowed to put bagged desiccant in bottled drugs, as long as the produced desiccant meets the national standard of "Medicinal Bagged Desiccant".

At present, the desiccant used in medicine is silica gel desiccant, and its main component is silicon dioxide (consistent with the composition of glass and sand). Stable chemical properties, no chemical reaction, non-toxic and harmless. Even if eaten by mistake, it will not be absorbed by the human body, will not cause harm to the body, and can be naturally excreted with feces.

Moreover, the production of medicinal desiccant must be carried out in a "million-level" aseptic workshop, so even if the desiccant is damaged in the medicine, there will be no problem, as long as the user detects it.

Of course, desiccant does not belong to medicine or health care products after all, so it is best to avoid eating by mistake. So now the packaging technology of desiccant has changed, and a desiccant placed in the bottle cap has appeared, which is safer.
