Here is a comprehensive overview of the treatment of infantile colic, based on authoritative clinical sources.
Infantile Colic — Treatment
Background
Infantile colic affects 20–30% of infants and accounts for ~95% of office visits for crying in children under 3 months. It is defined by Wessel's "rule of 3s": crying ≥3 hours/day, ≥3 days/week, for ≥3 weeks. It peaks at 6 weeks, diminishes by 9–12 weeks, and resolves by 4–5 months. The pathophysiology is unknown — no single cause has been proven.
1. Parental Reassurance (First-Line)
The cornerstone of management is reassurance and support:
- Establish that crying does not indicate serious illness or poor parenting
- Schedule frequent follow-up visits (every 1–2 weeks) to provide ongoing support and confirm normal growth/development
- Screen mothers for perinatal anxiety and depression, which increase risk of adverse infant outcomes
- Warn about and watch for signs of child abuse ("shaken baby syndrome") — parents under extreme stress may need respite care; hospitalization of parent and child may be considered in severe cases
2. Feeding Modifications
- Breastfed infants: Trial of a low-allergen maternal diet, particularly eliminating cow's milk protein (also nuts, eggs, wheat if needed)
- Bottle-fed infants: Switch to a protein-hydrolysate formula (or whey hydrolysate); soy formula is an occasional option
- Important: Colic is NOT linked to GERD — proton pump inhibitors are not indicated
3. Soothing/Behavioral Strategies
These provide temporary relief and give parents something active to do:
- Rhythmic rocking or patting
- Use of a pacifier
- Warm baths
- Car rides
- Swaddling
Note: These help during application but are generally ineffective once stopped. Their value is largely in reassuring caregivers and giving them agency.
4. Probiotics
- Lactobacillus reuteri DSM 17938 has shown reduction in crying time vs. placebo in some trials
- Can be recommended for breastfed infants only at this time
- Results have not been consistently replicated in larger trials
A 2024 systematic review (PMID 38720550) evaluated lactase supplementation for colic — evidence remains limited.
5. Pharmacologic Options (Limited Role)
| Drug | Status |
|---|---|
| Dicyclomine (Bentyl) | More effective than placebo, but contraindicated <6 months (risk of apnea, drowsiness, constipation) |
| Simethicone | No evidence of benefit |
| Herbal teas (chamomile, fennel, licorice, vervain) | Sometimes used; may reduce formula intake → risk of malnutrition; use with caution |
| Antihistamines (e.g., diphenhydramine) | Not proven effective |
| Proton pump inhibitors | Not indicated |
6. Treatments Lacking Evidence
The following have no proven benefit:
- Chiropractic or osteopathic manipulation
- Infant massage
- Acupuncture
- Simethicone
- Swaddling (as a treatment, not soothing measure)
Red Flags Requiring Workup
Colic is a diagnosis of exclusion. Investigate if:
- Fever → rule out infection (UTI, meningitis, bacteremia, etc.)
- Abdominal distension → rule out pyloric stenosis, Hirschsprung disease, volvulus, NEC, incarcerated hernia
- Lethargy → rule out hydrocephalus, meningitis, subdural hematoma, sepsis
Organic causes account for <5% of inconsolable crying.
Key Takeaways
- There is no cure — management is primarily supportive
- Most medications are ineffective or unsafe in this age group
- Reassurance, frequent visits, and caregiver support are the most evidence-based interventions
- Colic has no proven long-term effects on cognition, behavior, sleep, or family functioning
