Table of contents:

Dulcolax (Bisacodyl) is a medication used to treat constipation (difficulty pooing), which can be prescribed by a doctor or purchased over the counter without a prescription. It is an effective and well-tolerated treatment option for people suffering from constipation.

Bisacodyl is known as a stimulant laxative. It works by increasing the movement of the intestines, helping the stool to come out. It works by stimulating the muscles of the large intestine, which helps to move stools along more quickly. It also increases fluid in the intestines, which helps soften stools and make them easier to pass.

Bisacodyl is a non-prescription drug used to treat constipation, discomfort in the digestive tract, and other issues related to bowel movements. It may also be used to clean out the intestines before a bowel examination/surgery.

Uses and Dosage

Bisacodyl medication is taken whole and not crushed, chewed, or broken. Taking it within one hour of antacids, milk, or milk products can disrupt the coating on the tablet, potentially leading to an increased risk of abdominal discomfort and nausea. Therefore, it is imperative to adhere to the instructions of your physician or pharmacist when taking this medication.

The dosage of Bisacodyl should not be increased or taken more frequently than instructed. It is possible that the effects of Bisacodyl may take 6 to 12 hours to manifest. Furthermore, this medication should not be taken for more than 7 days unless otherwise recommended by a healthcare professional.

It should be tailored to the individual, considering age, medical condition, and treatment response.
