The antidiarrheal effect of Semicarb is relatively mild. For the elderly, infants, children and pregnant women, it can be considered to give Simethicone, also known as montelukast, orally. This drug has no side effects because it acts as an astringent and is mostly not absorbed by the intestine, so it is suitable for the treatment of special people, but it is relatively mild in action. It is recommended to take one packet once, three times a day. If the antidiarrheal effect is not good, it can be added to two to three packets three times a day. So for this drug, only for mild diarrhea, stools two to three or three to five times a day, can play a role in improving. For strong or acute diarrhea, additional related drugs such as loperamide hydrochloride capsules need to be given to treat the symptoms.
