From the Guidelines

Thalidomide is not recommended for treating hiccups due to its severe side effects and the availability of safer alternatives. The provided evidence does not support the use of thalidomide for hiccups, and its potential benefits are outweighed by the risks of severe birth defects, peripheral neuropathy, blood clots, and other significant side effects 1.

Alternatives for Hiccup Treatment

For hiccups, physicians typically recommend safer first-line treatments such as:

  • Breathing techniques
  • Sips of cold water
  • Medications like baclofen, chlorpromazine, or metoclopramide

These alternatives are preferred due to their more favorable safety profiles and established efficacy in treating hiccups.

Thalidomide's Risk Profile

Thalidomide is a highly regulated medication available only through special restricted distribution programs due to its teratogenic effects. Its side effect profile is a significant concern, with common side effects including constipation, dizziness, and malaise 1.

Conclusion on Thalidomide for Hiccups

Given the availability of safer alternatives and the serious risk profile of thalidomide, it should not be used for hiccup management. The potential mechanism for thalidomide in hiccups may relate to its anti-inflammatory and immunomodulatory effects, but this remains speculative and unproven. Therefore, thalidomide is not a recommended treatment option for hiccups, and other interventions should be tried before considering experimental treatments like thalidomide 1.

From the Research

Thalidomide for Hiccups

  • There is no direct evidence to suggest that thalidomide can be used for hiccups 2, 3, 4, 5.
  • The studies reviewed focus on the treatment of hiccups using various pharmacological agents, including baclofen, metoclopramide, gabapentin, and chlorpromazine 2, 3, 4, 5.
  • Thalidomide is mentioned in one study as a drug with various clinical applications, including the treatment of inflammatory disorders and cancers, but its use for hiccups is not discussed 6.
  • The available evidence suggests that the treatment of hiccups should be directed at the underlying condition, and if the cause is unknown or not treatable, a range of pharmacological agents may provide benefit 2, 3, 4, 5.
