Constipation is an oral medication used to treat constipation. After taking the medication, it will stimulate the small intestine and large intestine to promote intestinal peristalsis, thus producing defecation. As for how long it takes to produce bowel movement after taking the medication, it depends on the degree of constipation and the individual’s physical condition and absorption. Usually, it will take 6-8 hours after taking the medicine to produce the effect of bowel movement and thus defecation. When taking oral poo-poo treatment to relieve constipation, it is important to note that milk should not be drunk within 2 hours before and after taking the medication. Drinking milk will lead to poor absorption of the medicine and affect its effectiveness. At the same time, you should swallow the whole tablet, not put it in water or drink and then take it, and you should not chew it. Patients with constipation need to pay attention to adjusting their dietary habits and eat more coarse foods, such as grains and cereals, fresh fruits and vegetables on a daily basis.
