Dulcolax Tablet: Uses, Dosage, Side Effects, Precautions and Alternates
| Generic name | Bisacodyl |
|---|---|
| Drug class | Laxatives |
| Forms | Tablet, Suppository, Rectal liquid |
Quick overview
Dulcolax Tablet (bisacodyl) is a laxative used to treat constipation and to help empty the bowels before surgery, colonoscopy, x-rays, or other intestinal medical procedures. It works by stimulating the lining of the lower bowel and helping water build up to soften stools. It is generally meant for short-term use, with common doses ranging from 5 mg to 10 mg once daily depending on age.
What is Dulcolax Tablet
Dulcolax is a laxative that stimulates bowel movements. It is used to treat constipation or to empty the bowels before surgery, colonoscopy, x-rays, or other intestinal medical procedures.
Dulcolax Tablet uses
- Constipation
- Bowel preparation before surgery, colonoscopy, x-rays, or other intestinal medical procedures
- Evacuation of the bowel before a radiological examination or as an enema alternative (under medical supervision)
Benefits of Dulcolax Tablet
- Produces a bowel movement within 6 to 12 hours when taken by mouth
- Helps relieve short-term constipation
How Dulcolax Tablet works
Dulcolax works by acting on the lining of the lower bowel to stimulate movement and helps water build up in the bowel to produce soft, formed stools.
Dulcolax Tablet dosage
Swallow the tablet whole with a full glass of water; do not crush, chew, or break it. Take the tablet by mouth; the suppository form is for use in the rectum only, and should never be taken by mouth. Avoid taking other medicines within 2 hours before or after using Dulcolax. Avoid drinking milk or taking an antacid within 1 hour before taking Dulcolax by mouth, as they may affect how well it works. Do not take Dulcolax tablets together with medicines that lower stomach acidity, such as antacids or proton pump inhibitors. Tablets generally produce a bowel movement within 6 to 12 hours.
Do not give to a child younger than 2 years old without a doctor's advice; children under 6 years should not use it, and children 6 to 10 years should only take it as directed for short-term use. Older adults should not use the rectal form without a doctor's advice. Drink plenty of water and consider adding more fibre to your diet while taking this medicine. Avoid straining while passing a bowel motion after taking Dulcolax, as dizziness and fainting have been reported. Use only as needed and not for longer than recommended, since overuse can affect normal bowel function or cause dependence on laxatives.
