Montelukast granules have certain antidiarrheal effect and fewer side effects, which can be chosen appropriately. 2. Bifidobacterium capsule: After the gallbladder is removed to cause diarrhea, considering that there may be intestinal flora disorders, this time you can also choose bifidobacterium capsule under the guidance of the doctor to carry out the treatment, to achieve the purpose of stopping diarrhea.
