In general, pregnant women can use Montmorillonite Powder cautiously under the guidance of a physician.

Montmorillonite, the main component of Montmorillonite Powder, is a natural mineral particle. After entering the body, it forms a protective layer within the intestines, covering the intestinal mucosal surface, where it binds to and inhibits viruses, bacteria, and their toxins in the gastrointestinal tract. Additionally, it helps repair and enhance the intestinal mucosal barrier's defense against harmful agents, thereby exerting an antidiarrheal effect.

As Montmorillonite Powder does not enter the circulatory system and is hardly absorbed into the bloodstream, it has no significant toxic effects or adverse impacts on pregnant women or the fetus. Therefore, it is often considered a relatively safe option for treating diarrhea during pregnancy. However, pregnant women should not self-medicate; the drug must be taken strictly according to medical advice, following the prescribed dosage and duration. Overuse may cause constipation. If diarrhea persists or is accompanied by symptoms such as fever or abdominal pain, prompt medical attention is necessary to identify other potential causes and avoid delays in treatment.

Additionally, pregnant women are advised to maintain good dietary habits and a healthy lifestyle to help prevent gastrointestinal diseases such as diarrhea.
