What are the management options for hiccups?

Management of Hiccups

For hiccups, first try physical maneuvers, then chlorpromazine 25-50 mg three times daily for persistent cases, with baclofen or gabapentin as alternatives if chlorpromazine is ineffective or contraindicated. 1

Classification of Hiccups

• Acute hiccups: less than 48 hours
• Persistent hiccups: more than 48 hours but less than 2 months
• Intractable hiccups: more than 2 months 1

First-Line Management: Physical Maneuvers

For brief episodes of hiccups, try these physical techniques to disrupt the hiccup reflex arc:

• Breath holding
• Drinking water rapidly
• Swallowing granulated sugar
• Pulling on the tongue
• Stimulating the uvula/pharynx
• Larson's maneuver (suprasternal pressure) 1, 2

Pharmacological Management

For Persistent Hiccups (>48 hours)

1. Chlorpromazine (First-line):

   • Initial dose: 25 mg three times daily
   • Can increase to 50 mg three times daily if ineffective after 2-3 days
   • FDA-approved specifically for intractable hiccups 1, 3
   • Monitor for side effects: hypotension, sedation, extrapyramidal symptoms
   • Use lower doses in elderly, debilitated, or emaciated patients 3

2. Alternative Medications (if chlorpromazine is ineffective or contraindicated):

   • Baclofen: Particularly for central causes of hiccups
   • Gabapentin: Especially for neuropathic-related hiccups
   • Metoclopramide: For peripheral causes, especially GI-related hiccups 1, 4

For Intractable Hiccups (>2 months)

• IV chlorpromazine under careful monitoring
• Dosage: 25 to 50 mg in 500 to 1000 mL of saline as slow IV infusion
• Patient should be lying flat in bed with close blood pressure monitoring 5

Treatment Based on Underlying Cause

Always evaluate for and treat underlying causes:

• For GI-related causes (most common): metoclopramide, proton pump inhibitors
• For central nervous system causes: baclofen
• For neuropathic causes: gabapentin
• For medication-induced hiccups: adjust or discontinue offending medication 1, 2

Common Underlying Causes to Investigate

• Gastroesophageal reflux disease, gastritis, gastric distention
• Myocardial infarction
• Brain tumors or stroke
• Renal failure
• Medication side effects (steroids, anti-Parkinson drugs, anesthetics)
• Alcohol intake
• Post-surgical (especially abdominal surgery) 1, 4

Advanced Interventions for Refractory Cases

For hiccups that don't respond to medication:

• Nerve blockade (phrenic or vagal)
• Acupuncture
• Nerve stimulation techniques 1, 2

Special Populations

• Elderly patients: Use lower doses of medications; start with 10-25 mg of chlorpromazine 3
• Debilitated patients: Use more gradual dose increases and lower maintenance doses 3, 5

Common Pitfalls to Avoid

• Failing to identify and treat underlying causes
• Using high doses of chlorpromazine in elderly or debilitated patients
• Continuing ineffective treatments without trying alternatives
• Overlooking medication side effects as potential causes of hiccups 1, 6

Remember that while most hiccup episodes are self-limited, persistent or intractable hiccups can significantly impact quality of life and may indicate serious underlying pathology that requires thorough evaluation and targeted treatment.
