Dulcolax is a medical product which has a laxative action. It contains an ingredient Bisacodyl. This ingredient causes an irritation of the bowel leading to the production of mucus in the large intestine. Due to the increased secretion of mucus, the intestinal motility is improved, and a normal process of defecation.


A pharmacological action develops slowly. A laxative action occurs within 6-8 hours during the peroral use of Dulcolax. If the medicine is used at bedtime, desires for stool will start in about 10 hours – in 30 minutes after awakening.


A slow onset of the effect is compensated by a good tolerance of Dulcolax. This medicine seldom causes side effects and has a high level of the pharmacological safety.


Dulcolax is used during:

In what dose is Dulcolax used?

Side effects

The use of Dulcolax may cause spastic pain in stomach, diarrhea, muscle weakness, or muscle spasms. A cause of the muscle spasms is probably a disorder of the water-electrolytic balance, and therefore it is necessary to consume more water during the appearance of these symptoms. Take at least 2-2,5 liters of water per day during the treatment.


An intestinal atoney may happen during a long-term application of the suppositories. The side effects are usually light and do not need a cessation of Dulcolax.
