Low potassium levels, also called hypokalemia, can affect people of all ages. Sometimes the condition is the result of a temporary condition--for example, if you perspire a lot during sports or intense exercise and you don't replace the water you've lost.
Diarrhea in infants. Children who have diarrhea may have less energy, dry eyes, or a dry, sticky mouth. They may also not wet their diaper as often as usual. Give your child fluids for the first 4 to 6 hours. At first, try 1 ounce (2 tablespoons) of fluid every 30 to 60 minutes. If you are nursing, keep breastfeeding your infant. If you are using formula, use it at half strength for 2 to 3 feedings after the diarrhea starts. Then begin regular formula feedings again.
Imodium is generally seen as a safe, effective remedy for the treatment of diarrhea in children over the age of 6. However, it is always a good idea to check with your child's doctor before giving them any medication, even if it is available over the counter.
