Laxatives

Miralax

Miralax is a product that that softens the stool and increases the frequency of bowel movements by retaining the water in the stool. It is a white powder that should be dissolved in a clear liquid such as juice or water.

The dose will depend on the age of the child and the degree of constipation. The bottle top is a measuring cap marked to 17 grams (one heaping tablespoon). The dose will range between 1/2 capful to one full capful 1 to 2 times a day. Miralax can be taken at any time. It is suggested that you take it in the morning. It can be taken on a full or empty stomach.

A successful treatment program requires time and effort. Miralax can usually be expected to work in 2 to 4 days. The length of time you will need to use Miralax will be determined by your doctor.

Side effects may include cramping or diarrhea. It may be necessary to cut the dose in half or take it every other day. You may call the pediatric surgery nurse to discuss an alternative-dosing plan.

Mineral Oil

Mineral oil is a type of laxative that coats the bowels and stool with a waterproof film. It keeps the stools moist and soft, but does not the effective of stronger laxatives. The bowels become "slippery" inside and the stools slide out easily. The dose of mineral oil may need to be adjusted to meet your child's needs. If the stools are too loose or if there is oil leaking into their underpants, the dosage may need to be decreased.

Mineral oil is tasteless and odorless. It may be taken plain or mixed with juice. Sometimes it is helpful to mix it with chocolate milk since the consistency is a little thicker.

Senekot

Senekot is a natural fiber that is used to treat functional constipation. It is a combination of a stool softener and a stimulant. Senekot will generally produce a bowel movement in 6-12 hours after taking it. You may plan your child's dose based on what would work best for their schedule. Senekot syrup is chocolate flavored and may be taken alone or added to milk. It is also available as granules or tablets.

Examples: Noon dose for evening bowel movement, Bedtime for a morning bowel movement

Try to give the dose at the same time each day to help establish a regular bowel pattern.
