Diarrhea: Antibiotic-Associated

What is antibiotic-associated diarrhea?

Many antibiotics cause diarrhea. This is not an allergic reaction. Antibiotics can upset the natural balance of bacteria in the digestive tract. Too many of the wrong kind of bacteria in the digestive system can cause diarrhea.

The diarrhea is usually mild and will not cause a child to become dehydrated or lose weight. The stools return to normal 1 or 2 days after the child finishes the antibiotic treatment.

How can I take care of my child?

Your child does not need to stop taking the antibiotic. Anti-diarrheal medicines are not necessary. Follow a regular diet with a few simple changes:

• Eat more foods containing starch. Starchy foods are easily digested during diarrhea. Examples are cereal, breads, crackers, rice, mashed potatoes, and noodles.
• Drink more water. Avoid all fruit juices and carbonated drinks.
• Milk and milk products are fine.
• Avoid beans or any other foods that cause loose bowel movements.

If stools are frequent, increase breast-feeding, or give more formula or water. Yogurt restores healthy bacteria to the digestive tract. If your child is over 12 months old, give him 2 to 6 ounces of yogurt (active culture) twice a day.

Sometimes the diarrhea causes a diaper rash. Wash the irritated area with water and then protect the skin with a thick layer of petroleum jelly or other ointment.

When should I call my child's healthcare provider?

Call IMMEDIATELY if:

• Blood appears in the diarrhea.
• Your child shows any signs of dehydration.

Call during office hours if:

• You want to stop the antibiotic.
• You have other concerns or questions.
