If you've been taking laxatives for a long time and can't have a bowel movement without taking a laxative, talk with your doctor about how you can slowly stop using them. If you stop taking laxatives, over time, your colon should start moving stool normally. Your doctor may suggest using a laxative for a short time.

What happens if laxatives don't work for constipation?

Stay in touch with your doctor while following your constipation treatment. You may need to switch treatments if one isn't working. It's possible to become dependent on laxatives and need them to have a bowel movement. In that case, your doctor may have to wean you off laxatives to get your system back to normal.

How long can constipation last after taking laxatives?

They promote the absorption of water into your bowels. This makes stools larger and softer which in turn makes them easier to pass. They take 12 to 24 hours for some effect and 48 to 72 hours for their full effect.
