What is Dulcolax?

Dulcolax is an effective laxative that helps regulate bowel movements. Dulcolax can be used for treating constipation or to cleanse the bowels prior to surgical procedures, such as colonoscopy, scans, or other medical procedures. Dulcolax tablets typically cause the bowel to move in between 6 and 12 hours. Dulcolax supplements usually cause stool movements within 15 minutes to an hour.


Follow the directions on your prescription label and on the label of your package. Inform your health care providers about your medical issues, allergies, and any other medications you take.

How to take Dulcolax?

Take Dulcolax as directed on the label or as directed by your physician. Avoid using it in larger than smaller quantities or for longer periods than the recommended duration. Laxatives that are used too often can cause your bowels to work incorrectly or could cause dependence on the use of laxatives. In some instances, Dulcolax is taken by mouth. The suppository can be used within the rectum. Do not chew, crush, or break the Dulcolax tablet. Suck the tablet completely into an entire cup of filtered water. Dulcolax taken in the mouth will result in a bowel movement in 6–12 hours. Dulcolax employed in the rectum may produce quicker results. The bowel should begin to move in 15 to 60 minutes following the use of a suppository for rectal. Do not consume a rectal suppository by mouth. It is only for use within your rectum. It is recommended that you empty your bladder before taking Dulcolax inside the rectum. Cleanse your hands prior to and after using rectal Dulcolax.

To make use of the rectal suppository:

  • Take off the wrapper from the suppository. Do not handle the suppository excessively, or it may melt in your hands. If the suppository feels soft, you can place it in cool water or freeze it for a couple of minutes.
  • Lying on your back with your right knee pointing up towards your chest Place the suppository gently into your rectum for approximately 1 inch. Point at the tip first.
  • Relax for a couple of minutes. The suppository will begin to melt, so you will feel very little or no pain while you are holding it within.
  • Don't use more than one suppository for rectal use each day.

Contact your physician if you are not experiencing regular bowel movements after taking this medication or if you experience constipation for more than seven days. If you're taking Dulcolax in preparation for an upcoming medical exam, be sure to follow the instructions of your doctor on when you should use the drug. Keep Dulcolax or rectal medication at room temperature away from heat and moisture.
