Dulcolax vs. Miralax

Dulcolax and Miralax are both types of drugs and they fall in the class of laxatives. These drugs are used in the treatment of constipation and bowel preparation, however, there are a few disparities hence advice from a physician is recommended. In this context, I will elaborate the differences between these two drugs.

What is Dulcolax?


Dulcolax is available in the form of tablets that are ingested through the mouth. It is used in the short-term relief of constipation and also aids in emptying the bowel prior to medical procedures such as surgery. This medicine should not be taken for long periods of time or used in excess as it may lower the potassium levels in the blood. Dulcolax may not be suitable for everyone hence, one should be keen to check the leaflet before taking it. If symptoms persist after 5 days of treatment, a doctor’s consultation is advised.

What is Miralax?


Miralax is also available in the form of tablets and besides treating constipation and bowel preparation, Miralax is also used in the treatment of constipation acute. Is currently FDA-approved for adults for seven days but it’s not approved for children. Despite its wide use, there is a little data on its efficacy and its tolerability.
