Treatment Options for Hiccups
For hiccups, start with physical maneuvers for acute cases, and use chlorpromazine (25-50 mg three times daily) as the first-line medication for persistent cases. 1
Classification of Hiccups
- Acute: Less than 48 hours
- Persistent: More than 48 hours but less than 2 months
- Intractable: More than 2 months 1
First-Line Treatment: Physical Maneuvers
For acute hiccups (<48 hours), try these techniques first:
- Breath-holding
- Rapid water drinking
- Swallowing granulated sugar
- Pulling on the tongue
- Stimulating the uvula/pharynx
- Larson maneuver (suprasternal pressure) 1
These physical interventions can effectively disrupt the hiccup reflex arc and are recommended by multiple medical organizations including the American Academy of Family Physicians.
Pharmacological Treatment Algorithm
For Persistent Hiccups (>48 hours)
First-line medication: Chlorpromazine
Alternative medications (if chlorpromazine is contraindicated or ineffective):
- Baclofen: Preferred for central causes of hiccups
- Gabapentin: Preferred for neuropathic-related hiccups
- Metoclopramide: Preferred for peripheral causes, especially GI-related hiccups 1
For Intractable Hiccups (>2 months)
- Consider IV chlorpromazine under careful monitoring 1
- Consider referral for advanced interventions:
- Nerve blocks
- Nerve stimulation
- Acupuncture 1
Special Considerations
Dosage Adjustments
- Elderly patients: Use lower doses and increase more gradually
- Debilitated or emaciated patients: Use lower doses and monitor closely 1, 2, 3
Monitoring and Precautions
- Monitor for hypotension, sedation, and extrapyramidal symptoms with chlorpromazine
- Be aware of QT prolongation risk, especially when combining with other medications that affect QT interval
- For IV administration of chlorpromazine, keep patient lying down for at least 30 minutes after injection 1, 3
Common Pitfalls to Avoid
Failing to identify underlying causes: Always investigate for conditions like gastroesophageal reflux disease, myocardial ischemia, or central nervous system disorders 1
Overlooking drug interactions: Particularly with QT-prolonging medications that can increase cardiac complications 1
Improper administration of chlorpromazine: For IM injection, administer slowly, deep into upper outer quadrant of buttock. For IV use (only for severe hiccups, surgery, and tetanus), always dilute to at least 1 mg/mL and administer at a rate of 1 mg per minute 3
Continuing ineffective treatments: If no improvement is seen after 2-3 days of oral therapy for intractable hiccups, switch to parenteral administration 3
The stepped approach to hiccup management allows for appropriate escalation of treatment based on duration and severity, prioritizing simpler interventions before moving to pharmacological options with potential side effects.
