Hiccups Treatment and Management

Understanding Hiccups and Their Causes

Brain tumors can cause hiccups, as stated by the American Academy of Pediatrics 1
Traumatic brain injury is a central nervous system cause of hiccups, according to the American Academy of Pediatrics 1

Chlorpromazine can cause hypotension, sedation, extrapyramidal symptoms, and QT interval prolongation, as reported by the American Academy of Pediatrics 1
Untreated persistent hiccups can lead to weight loss, as noted by the American Academy of Pediatrics 1
Untreated persistent hiccups can lead to depression, according to the American Academy of Pediatrics 1

The American Society of Clinical Oncology recommends metoclopramide as a second-line agent for the treatment of hiccups, as studied in randomized controlled trials 2

The National Comprehensive Cancer Network suggests considering metoclopramide as an alternative treatment for hiccups, based on available data 2

The American Thoracic Society recommends initiating high-dose proton pump inhibitor (PPI) therapy for patients with gastroesophageal reflux disease (GERD) as the suspected cause of persistent hiccups, with response time variable from 2 weeks to several months, and consideration of adding prokinetic therapy if partial or no improvement occurs 3
For patients with persistent hiccups due to GERD, the American Gastroenterological Association supports the use of PPI therapy, with the option to add prokinetic therapy, such as metoclopramide, if symptoms persist, and consideration of 24-hour esophageal pH monitoring if empiric therapy is unsuccessful 3

The American Gastroenterological Association recommends implementing antireflux diet and lifestyle modifications concurrently for patients with persistent hiccups 4

The American Society of Clinical Oncology is not mentioned in the context of the provided citation, however, antireflux diet and lifestyle modifications are recommended concurrently 4

Local compression symptoms such as hiccups suggest pericardial effusion compressing the phrenic nerve, as noted in the European Heart Journal guidelines 5
Imaging, including chest X-ray and echocardiography, is recommended if pericardial or thoracic pathology is suspected, according to the European Heart Journal 5

The European Society of Cardiology implies that pericardial effusion compressing the phrenic nerve can cause hiccups, and recommends imaging studies such as chest X-ray and echocardiography for diagnosis 5

The National Comprehensive Cancer Network recommends metoclopramide as a second-line agent for intractable hiccups when chlorpromazine fails or is contraindicated, with a dosing of 10-20 mg orally or IV every 4-6 hours 6, 7
The National Comprehensive Cancer Network suggests an alternative dosing for gastroparesis-related hiccups with metoclopramide, 5-10 mg orally four times daily, 30 minutes before meals and at bedtime 6
Haloperidol may be used as a breakthrough option for intractable hiccups, with a dosing of 0.5-2 mg orally or IV every 4-6 hours 7
Olanzapine may be used as a breakthrough option for intractable hiccups, with a dosing of 5-10 mg orally daily, and has Category 1 evidence for breakthrough symptoms 7
Corticosteroids, such as dexamethasone 4-8 mg BID-TID, may be considered for central nervous system involvement in intractable hiccups 6
