From the Guidelines

Tylenol (acetaminophen) is not recommended for treating constipation in an 8-month-old infant. Acetaminophen is a pain reliever and fever reducer, but it does not have any effect on bowel movements or constipation. For infant constipation, more appropriate remedies include:

  • Ensuring adequate fluid intake, particularly water if the baby is eating solid foods
  • Offering high-fiber foods if solids have been introduced (such as pureed prunes, pears, or peaches)
  • Gentle belly massage or bicycle leg exercises
  • Small amounts of diluted fruit juice like apple or pear juice (1-2 ounces) can also help, as suggested by the North American Society of Pediatric Gastroenterology, Hepatology, and Nutrition constipation guideline 1 If constipation persists, consult your pediatrician who might recommend an infant-specific osmotic laxative or glycerin suppository. Constipation in infants is typically caused by dietary factors, dehydration, or the transition to solid foods, and requires treatments that specifically address bowel function rather than pain management medications like Tylenol. It's essential to note that the study on fruit juice in infants, children, and adolescents 1 provides guidance on the appropriate use of fruit juice for constipation, but it does not support the use of Tylenol for this purpose.

From the Research

Treatment of Constipation in Infants

  • The provided studies do not specifically address the use of Tylenol (acetaminophen) for treating constipation in infants 2, 3, 4, 5, 6.
  • For an 8-month-old infant with constipation, treatment options may include hyperosmotic laxatives such as lactulose or polyethylene glycol, depending on the infant's age and weight 2, 3.
  • It is essential to consult a pediatrician before administering any medication to an infant, as they can provide guidance on the appropriate treatment and dosage.

Constipation Treatment Options

  • Polyethylene glycol is effective and well-tolerated for treating constipation in infants over 6 months old 2, 3.
  • Lactulose/lactitol-based medications are authorized and effective for infants under 6 months old 2.
  • Mineral oil is less commonly prescribed due to potential side effects 2, 3.
  • Abdominal massage may be a non-invasive and inexpensive treatment option for constipation, although more research is needed to confirm its effectiveness 4.

Important Considerations

  • Before treating constipation, it is crucial to rule out any underlying medical conditions that may be causing the constipation 3, 5, 6.
  • A pediatrician should be consulted to determine the best course of treatment for an 8-month-old infant with constipation, as they can assess the infant's overall health and provide personalized guidance.
