  • How long does it take for dulcolax to work

    It may take 6 to 12 hours before this medication causes a bowel movement.

  • How does dulcolax work

    Dulcolax works by stimulating the nerve endings in the walls of the large bowel and rectum. This makes the muscles in the bowel wall contract more often and with increased force, which moves the stools through the colon to the rectum so that the bowel can be emptied.

    For constipation, the usual dose for adults and children over 12 years of age is 1 to 2 pills (5 to 10 mg) taken by mouth, or 1 adult suppository (10 mg) inserted rectally. For children 6 to 12 years of age, the usual dose is 1 pill (5 mg) taken by mouth or 1 pediatric suppository (5 mg) inserted rectally.

Dulcolax is the best thing for me. It works few hours after taking the pill. I did not experience any of the side effects. It is a great way for someone who is really constipated to get relief fast.

I take 2-3 dulcolax every night just before bedtime and have had NO problems. I'm up at 7 and on the throne within 10-15 minutes.


I hate Dulcolax. These pills did get me the worst cramps in my entire life. I just have to smell them and I instantly have to throw up.


I have degenerative disc disease and this medication helps. It does not make me drowsy like some other muscle relaxers. It isn't quite as dramatic in it's effect but the alternative is worse; like taking Flexeril and having to sleep! Skelaxin works about the same if not a little better but is really expensive so I am glad this much less expensive alternate works for me. This medication allows me to function and receive some moderate relief.

Prescribed Cyclobenzaprine 10mg for a short trial period to assist with relaxing undetermined back muscular pain. I would take it in the evening, and Cyclobenzaprine did help me relax, but did little for the pain. Weird though... every single instance, I would get a good night of sleep, but just be bitchy/moody/on edge the entire next day.


I've had Flexeril prescribed for back pain for many years now. It really work for me. The main side effect is drowsiness. Makes me really sleepy. For that reason, I take it before bedtime.
