CeraLyte FAQ Part IV

by Mike Nelson September 20, 2016


How much per day should be given to an adult? What is the normal length of use?


The goal is to replace the amount of fluid lost (if you lose a cup drink a cup). An average person 10 years of age or older with diarrhea should slowly drink the contents of one ready to drink package (11 ounces) or the contents of one 10-gram packet dissolved in about 7 ounces of water after every loose stool. Greater amounts may be needed if large amounts of fluid are lost with the diarrhea or if vomiting is involved. A general rule is to continue taking CeraLyte until the urine is a pale yellow with good flow every two to four hours. An initial starting dose of approximately one liter over one to two hours is often an adequate starting point.

Oral fluids should not be withheld from anyone who is thirsty (unless medically necessary) since this is a typical sign that the patient is not adequately hydrated. Patients who are severely dehydrated may have difficulty drinking. The duration of CeraLyte use depends upon the type of illness. Some patients (including pediatric patients) suffering from chronic ailments, and under the supervision of their physician, will rely on CeraLyte throughout their lives.


What should be done if diarrhea continues?


If the patient’s diarrhea continues for more than one or two days or gets worse they should seek medical attention. Medical treatment should be sought right away if any of the following warning signs are present:

  • Severe diarrhea, possibly including vomiting
  • Dehydration symptoms, including
  • Sunken eyes or, for infants, sunken fontanel ("soft spot" at the top of the head)
  • Loss of skin turgor, rapid pulse with low blood pressure, cold clammy extremities
  • Excessive thirst or dry mouth
  • Decreased urine or no urine or dark urine (it should be pale in color)
  • Very ill appearance, listless or fainting
  • High temperature (over 103°F)
  • Blood in the stool; severe abdominal cramps

Can CeraLyte be administered through an NG tube?


CeraLyte can be given via an NG tube or gastrostomy ("G" tube) but should be done so only under close medical supervision. The amount to be given should match the amount lost by diarrhea. The best way to judge adequate dose is good urine flow (50-100 ml/hour) with pale colored urine. Initially, in moderate dehydration, the dosage should be 20 ml/kg/hour for 2 - 3 hours to match losses. Check for residual fluid in the stomach if patient becomes distended or vomits. Slow the rate of infusion if residuals are more than 50 ml until the residuals diminish.
