From the Guidelines
Meclizine is not recommended as the first-line treatment for vertigo due to its potential to interfere with central compensation in peripheral vestibular conditions, and instead, ondansetron, a serotonin-5-hydroxytryptamine-3 antagonist, may be considered for treating vertigo-related nausea and vomiting. When considering the treatment of vertigo, it's essential to prioritize medications that do not hinder the body's natural compensatory mechanisms. According to the most recent guideline evidence 1, clinicians should not routinely treat BPPV with vestibular suppressant medications such as antihistamines and/or benzodiazepines, as this can interfere with the body's ability to compensate for the vestibular disorder.
Some key points to consider when treating vertigo include:
- The use of vestibular suppressant medications, including antihistamines like meclizine, is not recommended for routine treatment of BPPV 1.
- Ondansetron, a serotonin-5-hydroxytryptamine-3 antagonist, may be effective in treating nausea and vomiting associated with vertigo, as it works on the central emetic center without interfering with vestibular compensation 1.
- It's crucial to differentiate between the treatment of vertigo itself and the treatment of accompanying symptoms like nausea and vomiting, as the approach to each may vary.
- For patients experiencing severe or persistent vertigo, a thorough medical evaluation is necessary to rule out underlying conditions that may require different treatment approaches.
In terms of specific treatment options, ondansetron may be considered for the treatment of vertigo-related nausea and vomiting, given its mechanism of action and the potential benefits in reducing symptoms without interfering with vestibular compensation. However, the decision to use any medication should be made on a case-by-case basis, considering the individual patient's condition, the underlying cause of vertigo, and potential side effects.
From the FDA Drug Label
Meclizine hydrochloride tablets are indicated for the treatment of vertigo associated with diseases affecting the vestibular system in adults. The best antiemetic for treating vertigo is meclizine.

From the Research
Antiemetic Options for Vertigo
- The best antiemetic for treating vertigo can depend on the specific cause of the vertigo, with different medications being more effective for different types of vertigo 3.
- For acute peripheral vertigo, a study compared the effectiveness of ondansetron and promethazine, finding that promethazine was more effective at reducing vertigo, while ondansetron was more effective at reducing nausea and vomiting 4.
- Other medications that may be used to treat vertigo include antihistamines, calcium channel blockers, and benzodiazepines, which can help reduce vertigo symptoms or prevent them from occurring in the first place 5.
- However, for certain types of vertigo, such as benign paroxysmal positional vertigo (BPPV), vestibular suppressants may not be effective and may even be counterproductive, with canalith repositioning maneuvers (CRMs) being a more effective treatment option 6.
Comparison of Antiemetics
- A review of comparative trials found that ondansetron and granisetron had equal antiemetic efficacy in reducing chemotherapy-induced nausea and vomiting, although this may not be directly applicable to vertigo treatment 7.
- The choice of antiemetic for vertigo may depend on the specific symptoms being experienced, as well as the potential side effects of the medication, with some medications being more effective for nausea and vomiting, while others may be more effective for reducing vertigo symptoms 4.
