Hi my daughter is 3 months old and weights about 13 pounds. She's keeps getting constipated and the doctor suggested miralax. What dosage do I give?

Constipation : Is your little one drinking formula or breast milk? Infants fed breast milk sometimes go many days without a bowel movement. If stools are not firm and there is no significant straining, it is usually safe to watch & wait up to one week. I am not aware of recommended dosage guidelines for Miralax in a young infant. Other options: prune or pear juice, mineral oil or glycerin suppositories. ...Read more

Can I up my dosage of miralax?

Can I up my dosage of miralax?

Is dose-dependent...: The more MiraLAX you take the faster it works. As a once over-the-counter dosed laxative you may not see results for 3-4 days, but as a multi-dosed colonoscopy preparation (when used under doctor's advice) expect laxation within hours. As with any laxative however understand its mechanism of action, its risks, & treatment goals & make sure you are not missing obstruction, dysmotility, inflammation ...Read more

Constipation: If your daughter is breastfed she can have a stool with each feeding, go once a day or go aslong as a week without having one. All this is normal and not considered constipation and as such MiraLAX is not needed. ...Read more

I really want to take my miralax dose down just by a little bit. Would that be safe?

I really want to take my miralax dose down just by a little bit. Would that be safe?

Usa as needed: Miralax is primarily a wetting agent, that has a variable dose that depends more on your diet and bowel habits. Most can vary the dose up or down to reach a personal best dose. A full suggested dose may work for many, but double or half will work best for others. Getting into a habit of scheduled emptying 1-2x daily can often let you wean off the material altogether, but i would do so gradually. ...Read more

No change expected: You take MiraLAX and ate after taking it. No change is expected in your bowels by eating after the miralax. Miralax works by holding onto water in your colon. This prevents the stool from becoming hard. If you eat it should not change the way MiraLAX works and you should have the regular bowel movent. See your doctor if you need MiraLAX all the time. ...Read more

Taking my nightly MiraLax dose and it didn't mix properly in the water. I swallowed clumps of powder. Is this okay??

Taking my nightly MiraLax dose and it didn't mix properly in the water. I swallowed clumps of powder. Is this okay??

Clumpy Miralax: It doesn't matter if you got some clumps. It will all get thoroughly mixed up in your stomach. Why do you need daily miralax at age 20? How about trying more natural ways to make bowel movements regular, like getting more fruits/veggies in your diet (apples, pears, prunes, broccoli, cauliflower, cabbage)? Consider eliminating cheese for a few weeks to see if that helps. Avoid fast/processed foods. ...Read more

What the right dose of miralax for a 4 month old baby?

What the right dose of miralax
 for a 4 month old baby?

I recommend 2.5-5 ml: but this depends a little on the size of your baby. Preschool children easily tolerate 1 cap full, which is 17 grams (about a tablespoon or 15ml). If dose is not effective in 8-12 hours, a repeat dose may be given until stool is soft. Too large a dose will cause diarrhea and can potentially cause dehydration, so be sure to offer fluids. ...Read more
