What medications can relieve symptoms of gastric pain in a child?

Medications for Relieving Gastric Pain in Children

For children with gastric pain, antispasmodic medications are the first-line pharmacological treatment, with H2 receptor antagonists or proton pump inhibitors recommended for suspected acid-related conditions. 1

First-Line Medications Based on Symptom Pattern

For Abdominal Pain/Spasms:

• Antispasmodic (anticholinergic) medications are recommended as first-line therapy when pain is the predominant symptom, particularly when exacerbated by meals 1
  • These medications help reduce intestinal muscle contractions and relieve pain
  • Should be used only after adequate hydration is ensured 1
  • Caution: Antimotility drugs like loperamide should NOT be given to children under 18 years with acute diarrhea 1

For Acid-Related Pain:

• H2 receptor antagonists:

  • Ranitidine: FDA-indicated for infants as young as 1 month 2
  • Famotidine: Available as a cherry-banana-mint flavored suspension (for children 1-16 years) 2
  • Important limitation: Can cause tachyphylaxis within 6 weeks, limiting long-term effectiveness 1, 2

• Proton pump inhibitors (for moderate to severe symptoms):

  • Omeprazole: FDA-approved for children 2-16 years for GERD treatment 3
  • Dosing: Based on weight and age, administered 30 minutes before meals 3
  • Caution: Long-term use associated with potential risks including bone density issues, kidney problems, and increased infection risk 3

Second-Line Medications for Persistent Symptoms

For Persistent Pain:

• Tricyclic antidepressants (for moderate to severe pain):
  • Low-dose amitriptyline or imipramine may be beneficial, particularly for diabetic gastroparesis 1
  • Note: Nortriptyline was not found effective for idiopathic gastroparesis 1
  • Start with low doses and monitor for side effects (sedation more common with tertiary amines) 1

For Nausea and Vomiting:

• Antiemetics (for children >4 years with significant vomiting):
  • Ondansetron can facilitate oral rehydration and reduce hospitalization needs 1
  • Caution: May increase stool volume as a side effect 1

Age-Specific Considerations

Infants and Young Children:

• Try non-pharmacological approaches first:
  • For breastfed infants: Consider maternal diet modification (2-4 week trial excluding milk and egg) 1
  • For formula-fed infants: Consider hydrolyzed protein or amino acid-based formula 1
  • Positioning changes: Upright or supervised prone position when awake 1

School-Age Children:

• For abdominal pain without clear organic cause, pharmacological interventions should be used cautiously 4
• The evidence for drug effectiveness in recurrent abdominal pain is of low quality 4
• Consider the biopsychosocial approach alongside medication 5

Important Precautions

1. Avoid antimotility drugs (e.g., loperamide) in children under 18 years with acute diarrhea 1

2. Monitor for side effects of acid suppressants:

   • H2 blockers: Risk of community-acquired pneumonia, gastroenteritis, and candidemia 2
   • PPIs: Risk of C. difficile infection, bone fractures with long-term use, and kidney problems 3

3. Use appropriate dosing from pediatric medication tables (see guideline dosing tables for specific medications) 1

4. Limit duration of acid-suppressive therapy to the shortest time needed 3

Remember that gastric pain in children often requires a comprehensive approach, and medication should be selected based on the suspected underlying cause, symptom pattern, and age of the child.
