Can dexamethasone (corticosteroid) cause hiccups?

Yes, Dexamethasone Can Cause Hiccups

Dexamethasone definitively causes hiccups as a recognized adverse effect, occurring in approximately 11% of patients, and this is formally listed in the FDA drug label. 1

Evidence from FDA Drug Label

The FDA label for dexamethasone explicitly lists hiccups as an adverse reaction under the "Other" category of adverse effects 1. This represents the highest level of regulatory acknowledgment that hiccups are a known side effect of dexamethasone therapy.

Clinical Incidence and Characteristics

A large 2024 telephone-based study of 2,000 patients found that 11% (95% CI 9-13%) of dexamethasone-treated patients developed hiccups 2. This represents the most robust epidemiological data available on this adverse effect.

Key Clinical Features:

• Male predominance: Dexamethasone-induced hiccups appear to be a male-predominant phenomenon 3
• Timing: Hiccups typically begin within 3 days after dexamethasone administration 3
• Duration: Can persist for 18+ hours to several days, with some cases lasting up to 72 hours after drug termination 4, 5
• Severity: Can be severely uncomfortable, causing:
  • Inability to eat or drink
  • Sleep disruption
  • Severe abdominal pain
  • Significantly diminished quality of life 4, 5

Route of Administration

Hiccups have been documented with all routes of dexamethasone administration:

• Oral 2
• Intravenous 2, 5
• Epidural 2, 4

Management Strategy

The most effective intervention is rotating from dexamethasone to methylprednisolone, which maintains therapeutic efficacy while eliminating hiccups 3.

A 2017 randomized, single-blind, crossover phase III trial demonstrated:

• Hiccup frequency: 84.8% with dexamethasone vs. 62.5% with methylprednisolone (p=0.04)
• Mean hiccup intensity (NRS): 3.5 with dexamethasone vs. 1.4 with methylprednisolone (p<0.001)
• When rotated from dexamethasone to methylprednisolone, hiccup intensity decreased from 3.5 to 0.9 (p<0.001)
• No difference in antiemetic efficacy between the two corticosteroids 3

Clinical Algorithm:

1. If hiccups develop on dexamethasone: Switch to methylprednisolone at equivalent anti-inflammatory doses
2. If dexamethasone must be continued: Discontinuation leads to gradual resolution, typically within 72 hours 5
3. For prevention in high-risk patients (males, history of dexamethasone-induced hiccups): Consider using methylprednisolone initially 3

Important Caveats

• While hiccups are not life-threatening, they should not be dismissed as trivial—43% of affected patients desired educational materials about this side effect 2
• Patients often report that healthcare providers minimize or ignore this complaint 2
• The mechanism appears specific to dexamethasone rather than a class effect of all corticosteroids, as methylprednisolone does not produce the same incidence 3
