What is Veozah and how it works for hot flashes
Veozah (fezolinetant) is a prescription medication used to treat moderate to severe hot flashes due to menopause. It is a neurokinin-3 (NK3) receptor antagonist, which means it blocks specific signals in the brain involved in flushing and temperature dysregulation that drive hot flashes. Approved by the U.S. Food and Drug Administration (FDA) in 2023, it offers an option for people who have not used or cannot tolerate hormonal therapies. This overview explains how it works, how to take it, what side effects and safety points to consider, and how it compares with other treatments.
What are hot flashes
Hot flashes are sudden feelings of heat, often in the upper body, that can cause skin reddening, sweating, and chills. They are common during menopause and perimenopause due to changing hormone levels affecting the body’s temperature control. The frequency and severity vary widely, and they can disrupt sleep, mood, and daily activities. Because hot flashes have multiple drivers in the brain and nervous system, treatments target different pathways to reduce their occurrence and intensity.
How Veozah treats hot flashes
Veozah reduces hot flashes by antagonizing neurokinin 3 (NK3) receptors in the brain. By blocking these receptors, it modulates signaling pathways that influence thermoregulation and vasomotor function. This mechanism can decrease the frequency and severity of hot flashes without relying on systemic estrogen. Clinical trials showed significant reductions in hot flash activity compared to placebo, with benefits consistent over time in many people. This makes it a useful option for people who need a non-hormonal alternative.
Clinical evidence and label details
Data from pivotal trials support the effectiveness and safety of fezolinetant for vasomotor symptoms. The FDA approval was based on study results showing meaningful improvements with consistent dosing. As with any long-term therapy, it is important to discuss benefits and risks with a healthcare professional and to follow the recommended monitoring plan.

How to take Veozah safely
Veozah is usually taken as one 100 mg tablet by mouth twice a day, with or without food. It is important to take it at regular intervals to maintain steady levels. Do not stop or change doses without medical advice. Your clinician may check liver function before and during treatment, especially if you have risk factors for liver disease. Do not use Veozah if you are pregnant or planning pregnancy due to potential risks to the developing fetus.
Side effects and what to watch for
Common side effects may include abdominal pain, diarrhea, nausea, insomnia, back pain, and hot flash symptoms themselves. Serious warnings include potential liver injury and fetal harm, so clinicians often monitor liver tests and advise effective contraception. If you notice symptoms such as persistent abdominal pain, dark urine, unusual tiredness, or yellowing of skin or eyes, contact your clinician promptly. Reporting side effects to your healthcare team helps ensure safe use and supports ongoing safety monitoring.
Who may or may not be suitable
Veozah may be suitable for people with moderate to severe hot flashes who cannot or prefer not to use hormonal therapy. It is generally not recommended during pregnancy. Caution is advised for people with liver disease or those taking medications that may interact with NK3 receptors. A thorough review of current medications, medical history, and pregnancy status helps determine suitability and dosing.
Comparing non-hormonal options
Several non-hormonal options exist for managing hot flashes. Some antidepressants, seizure medications, and certain blood pressure drugs can reduce hot flash frequency for some people. Lifestyle measures like dressing in layers, avoiding triggers, and practicing paced breathing may help as well. Below is a brief comparison highlighting differences between approaches:
- Veozah (fezolinetant) — NK3 receptor antagonist; specifically approved for vasomotor symptoms; non-hormonal; prescription required
- Certain antidepressants — may reduce hot flashes for some people; sometimes used off-label; may affect mood or sleep
- Gabapentin and similar agents — may help with hot flashes and night sweats; can cause drowsiness or dizziness
- Lifestyle strategies — low risk; may provide partial relief; useful alongside or instead of medication
When to talk with your clinician
Consider discussing Veozah if you have moderate to severe hot flashes that affect daily life and you are looking for a non-hormonal option. Also talk with your clinician if you have liver disease, take other prescription medicines, are pregnant or planning pregnancy, or have concerns about side effects. They can review your medical history, current drugs, and preferences to decide if Veozah is a good fit and how to use it safely over time.
