From the Guidelines
Daily use of Miralax (polyethylene glycol 3350) is not recommended for long-term management of chronic constipation without medical supervision, as it may lead to electrolyte imbalances, dependency, and mask underlying digestive conditions 1. When considering the management of chronic idiopathic constipation, it's essential to weigh the potential benefits and risks of daily Miralax use. According to the American Gastroenterological Association-American College of Gastroenterology clinical practice guideline, polyethylene glycol (PEG) 3350 has been shown to be efficacious in increasing complete spontaneous bowel movements (CSBMs) and spontaneous bowel movements (SBMs) in individuals with chronic idiopathic constipation (CIC) for up to 6 months 1. However, the guideline also notes that PEG is approved by the FDA for the treatment of occasional constipation, not CIC, and its long-term use may be associated with side effects such as bloating, flatulence, and diarrhea 1.
Some key points to consider when evaluating the use of Miralax for daily management of constipation include:
- Electrolyte imbalances: Long-term use of Miralax may lead to electrolyte imbalances, particularly affecting potassium, sodium, and magnesium levels in the body 1.
- Dependency: Chronic use of Miralax may cause the bowels to become less responsive to natural stimuli, making it difficult to have bowel movements without the medication.
- Masking underlying conditions: Daily use of Miralax may mask underlying digestive conditions that require different treatment approaches.
- Alternative approaches: Dietary changes, regular physical activity, and establishing consistent bathroom routines may be more effective and sustainable for long-term management of chronic constipation.
It is crucial to consult with a healthcare provider to evaluate the underlying cause of constipation and develop a personalized treatment plan that may include alternative laxative options or other management strategies 1.

From the Research
Daily Use of Miralax Problems
- The daily use of Miralax, also known as polyethylene glycol (PEG), has been studied in various contexts, including its effectiveness and safety in treating constipation in both children and adults 2, 3, 4.
- Research has shown that PEG is an effective and safe therapy for both long and short term treatment of pediatric functional constipation 2.
- In adults, there is good evidence to support the use of PEG as a laxative therapy for chronic constipation, with studies demonstrating its efficacy and safety 3, 4.
- However, the long-term use of Miralax has not been extensively studied, and its potential effects on the gut microbiome and bowel function are not fully understood.
- Some studies have raised concerns about the potential for Miralax to cause dependence and decrease the natural motility of the bowel over time, although more research is needed to confirm these findings.
Potential Risks and Side Effects
- Common side effects of Miralax include diarrhea, nausea, bloating, and abdominal pain 4.
- Long-term use of Miralax may also lead to electrolyte imbalances and other nutritional deficiencies if not properly monitored.
- It is essential to follow the recommended dosage and usage guidelines for Miralax to minimize the risk of adverse effects.
Alternative Therapies
- Other laxative therapies, such as senna and psyllium, have also been shown to be effective in treating constipation, although their safety and efficacy profiles may differ from those of Miralax 3, 5, 4.
- A healthcare professional should be consulted to determine the best course of treatment for individual cases of constipation, taking into account the underlying cause and any potential interactions with other medications.
