From the Guidelines
Valium (diazepam) is not generally recommended as a first-line treatment for nausea. While it may occasionally help with nausea associated with anxiety or vestibular disorders, there are much more effective and appropriate anti-nausea medications available. For nausea, doctors typically prescribe medications like ondansetron (Zofran), promethazine (Phenergan), metoclopramide (Reglan), or dimenhydrinate (Dramamine), depending on the cause of the nausea. Valium is primarily a benzodiazepine that works by enhancing the effect of the neurotransmitter GABA in the brain, producing sedative, anxiety-reducing, and muscle relaxant effects. It doesn't directly target the neurological pathways involved in nausea and vomiting like true antiemetics do. Additionally, Valium carries risks of dependence, sedation, and other side effects that make it unsuitable as a nausea treatment.
According to the most recent and highest quality study, the use of valium for nausea is not supported 1. Instead, other agents such as phenothiazines, dopamine receptor antagonists, serotonin receptor antagonists, and corticosteroids are recommended for the management of nausea. In some cases, olanzapine, scopolamine, dronabinol, or nabilone may be considered for the treatment of nausea, especially when other treatments have failed 1.
Some key points to consider when treating nausea include:
- Identifying and addressing the underlying cause of nausea
- Using prophylactic treatment with antiemetic agents when necessary
- Considering alternative therapies such as cannabinoids or olanzapine when standard treatments fail
- Being aware of the potential risks and side effects of different medications, including valium.
It's essential to consult with a healthcare provider to determine the best course of treatment for nausea, as they can recommend an appropriate medication based on the underlying cause of the symptoms.

From the Research
Effectiveness of Valium for Nausea
- There is no direct evidence in the provided studies that Valium (diazepam) is effective for treating nausea 2, 3, 4, 5, 6.
- The studies primarily focus on the use of other medications such as ondansetron, metoclopramide, and dexamethasone for nausea and vomiting 3, 4, 6.
- Valium is mentioned in the context of its effects on human psychomotor and cognitive functions, but not specifically for its antiemetic properties 5.
- The most effective medications for preventing nausea and vomiting are identified as aprepitant, ramosetron, granisetron, dexamethasone, and ondansetron, with Valium not being mentioned as an option 6.
Valium's Primary Use
- Valium is primarily used for its anxiolytic, anticonvulsant, hypnotic-sedative, and muscle-relaxant properties 2, 5.
- It is not commonly associated with the treatment of nausea and vomiting, which are typically managed with other classes of medications 3, 4, 6.
Limitations of Current Evidence
- The provided studies do not offer conclusive evidence on the effectiveness of Valium for nausea, highlighting a gap in research on this specific topic 2, 3, 4, 5, 6.
- Further studies would be necessary to determine if Valium has any benefits in treating nausea and vomiting, although current evidence suggests other medications are more effective for this purpose 6.
