Intractable Hiccups
Intractable hiccups are repetitive involuntary diaphragm spasms lasting more than a month, often disrupting sleep, eating and recovery from illness.
Key takeaways
- Hiccups lasting beyond 48 hours warrant assessment; prolonged episodes are a symptom rather than a standalone diagnosis.
- Reflux, central nervous system disease, chest or abdominal irritation, metabolic disturbance and medicines are possible causes.
- Baclofen, gabapentin, metoclopramide and chlorpromazine have selected roles but different neurological and interaction risks.
The listings below do not identify why hiccups persist; treatment should follow examination and cause review.
Looking for the cause
History covers onset, surgery, reflux, swallowing, neurological symptoms and new medicines. Examination and tests are guided toward electrolytes, kidney or liver function, chest disease and brain or abdominal pathology. Treating reflux or stopping a culprit medicine may resolve symptoms.
Symptom treatment
Simple breath-holding or cold-water manoeuvres are reasonable for brief episodes but unreliable for intractable hiccups. Prescription options affect dopamine, GABA or other pathways and require caution with sedation, kidney function, movement effects and falls. Nutrition and sleep support may be necessary.
When to seek urgent care
Seek urgent care for hiccups with new weakness, speech difficulty, severe headache, chest pain, breathing difficulty, repeated vomiting, inability to eat or drink, confusion or marked dehydration.
