I have solid textbook and web information. Here's a practical answer.

Remedy for Hiccups (Singultus)

Hiccups happen when the diaphragm and intercostal muscles spasm involuntarily, followed by sudden closure of the vocal cords ("hic" sound). Most cases are benign and self-limited (under 48 hours), so simple physical maneuvers work for the vast majority.

First-line home remedies (stimulate the vagus nerve or raise CO2)

Swallow a teaspoon of dry granulated sugar - as effective as most other maneuvers and easiest to do - Tintinalli's Emergency Medicine, p. 470
Sip or gargle ice-cold water, or drink water quickly from the far side of a glass
Hold your breath for 10-15 seconds, or breathe slowly into a paper bag (raises blood CO2, which suppresses the reflex)
Pull on your tongue, press on your eyes gently, or stimulate the back of the throat/gag reflex
Bite into a lemon or take a small amount of vinegar
Have someone startle/frighten you (interrupts the respiratory cycle)

None of these maneuvers has been shown to be reliably more effective than another - they all work by interrupting the reflex arc (phrenic nerve, vagus nerve, and thoracic sympathetic chain) via pharyngeal or vagal stimulation - Tintinalli's Emergency Medicine, p. 470.

If hiccups persist beyond 48 hours (persistent) or a month (intractable)

Persistent hiccups can signal an underlying problem (gastric distention, GERD, a foreign body/hair touching the eardrum stimulating the vagus nerve, CNS lesions, uremia, or drugs like dexamethasone/chemotherapy), so it's worth a medical evaluation rather than continuing home remedies alone - Sleisenger and Fordtran's Gastrointestinal and Liver Disease, p. 337; Tintinalli's Emergency Medicine, p. 470.

Medical treatment options a doctor may use, from most to least established:

Chlorpromazine - the only FDA-approved drug for intractable hiccups (25-50 mg IV, then 25-50 mg orally 3-4x/day)
Metoclopramide - 10-20 mg orally 3x/day
Baclofen - 10 mg orally 3x/day, titrated up
Gabapentin - 100 mg orally 3x/day, titrated up
Haloperidol or nifedipine - alternative options (Doses per Tintinalli's Emergency Medicine, p. 471)

For hiccups in the setting of serious illness (e.g. palliative/cancer care), oral baclofen, chlorpromazine, metoclopramide, or haloperidol are commonly used - Textbook of Family Medicine, p. 96.

A quick check for recent evidence on non-drug approaches:

Searching PubMed

hiccups treatment

Note on recent evidence: A 2025 systematic review/network meta-analysis (PMID: 41346981) found acupuncture may help with intractable hiccups, and another 2025 review (PMID: 40055925) discusses IV lidocaine and other approaches for perioperative hiccups. These are more relevant to persistent/refractory cases in clinical settings than to ordinary everyday hiccups, and evidence quality for acupuncture remains limited/mixed - so they supplement rather than override the standard first-line advice above.

Bottom line: For an ordinary bout of hiccups, try swallowing a spoonful of sugar, sipping ice water, holding your breath, or breathing into a paper bag - one of these usually resolves it within minutes. See a doctor if hiccups last more than 48 hours, disrupt eating/sleeping, or are accompanied by other symptoms (weight loss, pain, vomiting), as this can indicate an underlying cause needing evaluation.
