Vertigo after a C2 nerve block is a possible side effect that typically resolves within hours to days, and the most effective treatment is rest and avoidance of sudden head movements, with ondansetron being a viable option for managing nausea and vomiting associated with vertigo, as shown in a study published in the American journal of otolaryngology 1. When experiencing vertigo following this procedure, it is essential to rest in a comfortable position and avoid sudden head movements. Over-the-counter medications like meclizine or dimenhydrinate can help manage symptoms, but their use should be approached with caution, especially in older adults, due to the potential risk of falls, as highlighted in a study published in the Journal of the American Geriatrics Society 2. Some key points to consider when managing vertigo after a C2 nerve block include:
- Resting in a comfortable position and avoiding sudden head movements
- Staying hydrated and considering having someone assist with daily activities until symptoms improve
- Avoiding the use of vestibular suppressants, such as meclizine and benzodiazepines, in older adults due to the potential risk of falls
- Considering the use of ondansetron for managing nausea and vomiting associated with vertigo, as it has been shown to be effective in reducing these symptoms 1
- Monitoring for persistent or worsening vertigo, severe headache, hearing changes, or neurological symptoms, and seeking medical attention immediately if these occur. It is also important to note that the C2 nerve is close to structures involved in balance and proprioception, and the anesthetic can temporarily affect these systems, leading to vertigo, as discussed in a study published in Seminars in neurology 3.
