Can I Give My Baby Miralax?

Can I give my baby Miralax?A constipated baby can be a cranky baby which may lead you to consider giving them Miralax.

When our child is constipated, they are often in pain—bloating, stomach upset, maybe even gassy. But unless your child is a toddler, your baby cannot tell you what is bothering him or her, which makes assessing their constipation even more difficult. But deciding whether or not your child is constipated can be tricky.

Most people believe that constipation refers to the frequency of bowel movements, but this is incorrect. While some people have a bowel movement at least once per day (or sometimes more), others may only have one every couple of days. This does not mean that they are constipated. The same goes for your child. If your baby is only having a bowel movement every couple of days, it does not mean they are constipated.

Being constipated depends on the consistency of your bowel movements. Soft bowel movements, whether every day or every few days, are considered healthy. If your baby’s bowel movement are hard nuggets or small, hard pebbles, this is constipation.

There are many treatments available to help cure constipation in children. Most doctors would first recommend using a natural laxative, such as prune or apple juice, to help alleviate any constipation. Having a diet that is rich in fiber will also help ensure your child has soft bowel movements.

Can I Give My Baby Miralax? Answer: As Directed by the Doctor

If natural laxatives do not work, your doctor may tell you to add “medicine” to their diet, such as Miralax. Miralax is a powder that is added to foods or drinks to help alleviate constipation. It does not have a taste, and your child should not even notice it is in their food or drink.

Consult with the Physician
When it comes to giving your child Miralax, though, you need to make sure you are giving him or her the correct dosage. Giving your child too little will not help them with their constipation, but giving them too much can also have adverse side effects. Finding out the correct dosage for your child usually depends on their age and weight. Most dosage recommendations can be found on the label of the medicine, but to be safe, you must always consult with your child’s physician before giving him or her any medication.

As for the frequency, this will usually be found on the medication’s label as well. Typically, Miralax is taken once per day for ten days, but always be sure to check with your child’s doctor.

Keeping the Dosage Accurate
Keep in mind that as a baby and toddler, your child is growing at a rapid pace. It is important to re-check the Miralax label for dosage instructions every time your child is suffering from constipation. If he or she has gained a pound or two since the last time they took Miralax, they may have moved into a different dosage bracket, requiring more medication in order to cure their constipation. If you do not pay attention to this, you could be undermedicating your child, which will not help them feel any better.

Along with Miralax and natural laxatives, there are other ways to treat constipation. Some people will use suppositories to help their child. Again, when your child is constipated, you should always consult with his or her doctor to see which remedies your doctor prefer you try. You should never give your child medication without your doctor’s consent.

Notes on Constipation
Remember, constipation refers to the consistency of the bowel movement, not the frequency. As long as your child is having soft bowel movements, it does not matter how often they occur. If your child’s bowel movements are hard or pebble-like, you should consult your child’s doctor for a constipation remedy. They may tell you to use juice, medication or suppositories. If your doctor decides that a treatment of Miralax is the solution, be sure to always give your child the correct dosage. Under- and over-medicating your child is not healthy.

As always, if you have any questions about the use of Miralax, the use of other constipation remedies, the consistency or frequency of your child’s bowel movements, or even constipation in general, it is always best to consult with your child’s doctor. He or she will be able to answer your questions and discuss your concerns in more thorough detail.

Hi Naeem,
Thanks for your comment. I would check with your doctor about the Miralax and talk to your pharmacist. It’s so hard when they are constipated, especially when it goes on for such a long time. Maybe your chemist has something they could recommend that you can get over the counter. I really couldn’t say anythig about giving medicines to your child, I am a mom, not a doctor. I hope it all works out for her and for you. When my little one is constipated I try them with a little pear juice in their water.
Best regard, Amber

September 2014 – Due to serious safety concerns raised in an FDA Citizen Petition filed by consumer group, Empire State Consumer Project (ESCP), the US Food and Drug Administration (FDA) agreed to study the effects of polyethylene glycol 3350 (PEG 3350) laxative use in children and issued a grant to the Children’s Hospital of Philadelphia to conduct the study. The group submitted the petition in 2012 on behalf of parents who say their children have been harmed by polyethylene glycol 3350 drug products. There is special concern about the safety of PEG 3350 laxatives like Miralax, which are not approved for use in children, and are not approved for more than seven days use. Many children are prescribed multiple daily adult doses by doctors off-label, often for months or years at a time. The ESCP petition calls for an investigation into the effects of PEG 3350 on children and a boxed warning on PEG 3350 products. The boxed warning was not granted, but the FDA has decided to update the labeling of prescription PEG 3350 bowel preparations with more stringent warnings and precautions for patients with certain health conditions.

The safety concerns reported in the FDA Citizen Petition are symptoms similar to those of ethylene glycol toxicity. The petition grant includes an agreement by FDA to study the potential for PEG 3350 to degrade into ethylene glycol (EG) and diethylene glycol (DEG), and to study the long term effects of PEG 3350 products on pediatric patients. Ethylene glycol and diethylene glycol are chemicals used to make antifreeze. Both are toxic to the central nervous system, liver, and kidneys when ingested. In recent history, DEG contaminated cough and acetaminophen syrups killed hundreds of adults and children. In 2007, the FDA issued a warning for consumers not to buy toothpaste from China, as some brands were made with DEG.

The FDA Adverse Event Reporting System (FAERS) shows over 7,000 adult and child adverse event reports that include at least one PEG 3350 product, including a number of deaths. The number of reports rose from 2,257 in 2012, when the FDA Citizen petition was filed. In 2009, the FDA Drug Safety Oversight Board acknowledged neuropsychiatric, metabolic, gastrointestinal, and kidney events in children who took PEG 3350 laxatives, but felt that “no action was required” at that time:

“The Drug Safety Oversight Board discussed reports of metabolic acidosis, metabolic acidosis with increased anion gap, and neuropsychiatric adverse events in children using polyethylene glycol (PEG) products. Metabolic acidosis is a disturbance in the body’s acid-base balance and causes too much acid in the blood. In some situations, metabolic acidosis can be a mild, chronic condition; however, it may lead to shock or death in severe cases. Neuropsychiatric adverse events may include seizures, tremors, tics, headache, anxiety, lethargy, sedation, aggression, rages, obsessive-compulsive behaviors including repetitive chewing and sucking, paranoia and mood swings.” “It is unknown if prolonged duration in solution would change the chemical properties of PEG-3350, and what the actual content of ethylene glycol or diethylene glycol or other low molecular weight PEG would be under such conditions.”

In addition to the ethylene glycol and diethylene glycol children may be exposed to through the degradation of PEG 3350, the FDA has tested 8 lots of polyethylene glycol 3350 and found ethylene glycol and diethylene glycol contaminants in the product itself:

“To better understand the level of polyethylene glycol impurities in PEG, the FDA Chemistry and Manufacturing group evaluated PEG 3350. This analysis of eight lots of PEG 3350 confirmed the presence of small amounts of ethylene glycol and diethylene glycol in all lots tested. Based upon the recommended daily adult dose of 17 mg daily dose PEG 3350, the maximum daily exposure of ethylene glycol would be 0.005 mg/kg/day for a 60 kg patient, or 0.015 mg/kg/day for a 20 kg pediatric patient (approx 5 years of age). Other low molecular weight PEGs were not included in this analysis. However, it is not known if any of these LMW species are absorbed and if so to what extent. Understanding the human absorption profile of LMW species is the first step needed in trying to understand the possible contribution of PEG 3350 use to the development of adverse events in children using this product chronically.”

Empire State Consumer Project has since petitioned the FDA to issue a Drug Safety Communication regarding the finding of ethylene glycol and diethylene glycol in all lots of PEG 3350 it tested, so that parents of study participants and all parents can be made aware of the potential for PEG 3350 to contain ethylene glycol and diethylene glycol. This petition for a Drug Safety Communication was denied. The EPA recommends that children not be exposed to more than 20 mg/L or 20 parts per million (ppm) of ethylene glycol in drinking water per one day or 6 mg/L or 6 ppm per day over 10 days. The adult doses of PEG 3350 tested were found to contain 0.3 mg of ethylene glycol of daily exposure for a 44 lb. child. This exposure is in addition to any EG and DEG exposure that may be found to occur from PEG 3350 degradation of the laxative products. The health effects of long term exposure of children to PEG 3350 are not known, although risks from short term exposure to EG and DEG are well documented in humans.

Empire State Consumer Project is a 501c3 registered Not-for-Profit Organization dedicated to reducing the use of chemicals toxic to human and environmental health. We accomplish this by educating consumers and industry, conducting product testing and reporting, and by advocating for regulation where needed to protect the public interest.
