In adults with diarrhea, the fastest way is to take oral laxatives, loperamide hydrochloride capsules plus montelukast. This medication facilitates the improvement of the number of diarrhea, while montelukast has the effect of an astringent, which is very helpful in improving the gastrointestinal dynamics and at the same time in reducing the number of diarrhea. However, it cannot be generalized, because some patients may have viral or bacterial infections. If repeated inflammatory infections are accompanied by nausea, vomiting and fever, they need to be treated actively with anti-inflammatory drugs as well as pain relief, body temperature reduction, and water-electrolyte replenishment. At the same time, it is necessary to pay more attention to rest, pay attention to local hot compresses, and give appropriate symptomatic treatment such as patchouli oral liquid. If the symptoms are not relieved repeatedly, it is necessary to improve the blood routine and ion analysis to clarify whether there are electrolyte disorders to assist in the diagnosis and treatment.
