Specific Precautions and Warnings With MiraLAXSome warnings and precautions to be aware of prior to using this laxative include the following:
- People with a blockage in the intestines (called a bowel obstruction) should not use this medicine.

Symptoms may include:
- Nausea and vomiting
- Abdominal (stomach) distention or swelling

- Although MiraLAX is not addictive, long-term use or overuse could result in dependence on laxatives to produce a bowel movement or an imbalance of body salts (electrolyte imbalance). Do not take this medication for longer than seven days without first talking to your healthcare provider.
- People with certain medical problems, such as kidney disease or IBS, should only take MiraLAX under the direction of a healthcare provider. Therefore, talk to your healthcare provider about using this laxative if you have one of these conditions.
- Rare cases of an allergic reaction have been reported in some people using MiraLAX. If you develop hives or a skin rash while using this laxative, stop using it and talk to a healthcare provider.
- It may take up to four days for MiraLAX to produce a bowel movement. Do not increase your dose if you do not have a bowel movement right away. Also, contact your healthcare provider if you do not have a bowel movement within four days.
- Certain lifestyle changes, such as adequate fiber and fluid intake and regular exercise, can help produce more regular bowel movements. Talk to your healthcare provider about other possible ways to avoid constipation.
- MiraLAX is unlikely to react with other medications (see MiraLAX Drug Interactions).
- MiraLAX is considered a pregnancy Category C medication. This means that it may not be safe for use during pregnancy, although the full risks are currently unknown. Talk to your healthcare provider about the risks and benefits of using this product when pregnant (see MiraLAX and Pregnancy).
