From the Guidelines

Sublingual administration of oxazepam does not increase its onset of action. The evidence suggests that alternative routes of administration, such as sublingual, do not offer a clinical advantage over conventional routes 1.

  • Conventional oral administration is the recommended route for oxazepam, with an onset of action of approximately 30 minutes to 1 hour [no direct evidence provided, but based on general medicine knowledge].
  • Sublingual administration is not a recommended or approved route for oxazepam, and it may not necessarily accelerate its effect 1.
  • Potential risks associated with sublingual administration of oxazepam, such as impaired respiratory function or other severe health complications, should be considered, and therefore, it is not advised to administer oxazepam sublingually [based on general medicine knowledge, no direct evidence provided].
  • If you have questions about the use of oxazepam, it is essential to consult with a doctor [based on general medicine knowledge, no direct evidence provided].

From the Research

  • There are no research papers provided that directly investigate the effect of sublingual administration of oxazepam on its onset of action.
  • The provided studies focus on various topics, including the safety of acetaminophen in older adults 2, the use of glucosamine in osteoarthritis management 3, drug-induced sialorrhea 4, the safety of astaxanthin supplements 5, and the oral delivery of nanoparticles 6.
  • None of these studies mention oxazepam or its sublingual administration, and therefore, do not provide evidence to answer the question.
