Perimenopause care
Perimenopause Hot Flashes
A hot flash is a sudden wave of heat, often across the face, neck, and chest. It may bring sweating, flushing, a faster heartbeat, or chills afterward. Episodes can begin while you still have periods, and treatment is available when they interrupt sleep or daily activities.

A typical episode rises quickly and then passes
Hot flashes commonly last one to five minutes. Some feel like brief warmth with little sweating. Others are intense enough that you need to stop what you are doing, remove a layer, or cool down. You may feel chilled or shiver afterward.
A faster heartbeat or a feeling of anxiety can accompany the heat. At night, the same type of episode is called a night sweat. Repeated episodes can disrupt sleep, concentration, and comfort at work or in social situations.
Hormonal changes affect the brain's temperature regulation during the menopause transition. Hot flashes can occur before the final period and continue for years afterward. The Menopause Society reports an average duration of seven to ten years for vasomotor symptoms, although an individual's course varies considerably.
A changing cycle alongside new heat episodes helps a clinician assess perimenopause. If symptoms begin before age 45, arrange an assessment because testing and treatment decisions may differ at younger ages.
Record frequency and impact before choosing treatment
For several ordinary days, note roughly how many episodes occur and which interrupt an activity. Include nighttime waking and whether you need to change clothes or bedding. A description of disruption helps guide treatment even if you cannot count every episode.
- Approximate number of daytime episodes and nighttime awakenings.
- Whether heat brings sweating, palpitations, chills, or anxiety.
- Activities interrupted, including work, exercise, or sleep.
- Menstrual changes and any new medicine or supplement.
Also note situations that seem to bring on an episode, such as a warm room, alcohol, hot drinks, or spicy food. Responses vary. A brief record can help you decide whether adjusting a particular habit makes you more comfortable.
Make episodes easier to manage during the day and night
Wear layers you can remove, keep a fan available, and choose bedding that is easy to adjust. A cooler room and a nearby change of nightwear can reduce the effort involved in a nighttime episode. At work, access to water and a cooler space may help you recover more comfortably.
These measures are reasonable ways to manage heat as it happens. Research on many lifestyle measures as treatments for the frequency of hot flashes is limited or inconsistent. If episodes remain disruptive, discuss options with stronger treatment evidence.
Regular activity and a nutritious eating pattern remain useful for general health. Menopause-specific CBT and clinical hypnosis have evidence for managing vasomotor symptoms or their impact. Ask whether a trained professional or suitable program is available.
Prescription treatment options
| Treatment | Benefits and practical considerations |
|---|---|
| Systemic hormone therapy | The most effective treatment for hot flashes. The choice of estrogen, route, and uterine protection depends on your history. |
| Certain antidepressants | Can reduce hot flashes. Low-dose paroxetine is approved for this use; other choices may be off-label and need an interaction review. |
| Gabapentin or oxybutynin | Used off-label for selected patients. Side effects and other conditions affect suitability. |
| Fezolinetant | A nonhormonal prescription with required liver monitoring and a serious liver injury warning. |
| Elinzanetant | A nonhormonal prescription requiring liver tests and review of pregnancy, daytime impairment, and seizure precautions. |
How hormone therapy is prescribed
Systemic estrogen may be given as a patch, tablet, gel, or spray. If you have a uterus, progesterone or another progestogen is generally needed to protect the lining. A clinician reviews abnormal bleeding and histories such as breast cancer, blood clots, stroke, heart attack, or liver disease before prescribing.
Your current cycle and pregnancy prevention needs matter too. For some eligible women, combined hormonal contraception can help manage symptoms and bleeding while providing contraception. Menopause hormone therapy itself does not prevent pregnancy.
Newer nonhormonal medicines have specific monitoring requirements
Fezolinetant is sold as Veozah. Liver blood tests are required before starting, monthly during the first three months, and at months six and nine. The FDA warns about rare but serious liver injury. Yellow skin or eyes, dark urine, unusual itching, pale stools, or abdominal pain require stopping the medicine and contacting the prescriber immediately.
Elinzanetant is sold as Lynkuet. Its label requires liver tests before treatment and at three months. It can cause sleepiness, dizziness, or other effects that impair daytime activities. If those effects occur, avoid driving or hazardous tasks until they resolve and contact the prescriber.
Lynkuet is contraindicated in pregnancy and requires pregnancy testing before use in people who could become pregnant. Effective contraception is required during treatment and for two weeks afterward. The label also includes seizure precautions. Review the current prescribing information and all other medicines before starting either product.
When heat or sweating needs further assessment
Sweating with a persistently fast heartbeat, shaking, or unexplained weight loss can occur with an overactive thyroid. Sudden fear with a racing heart and breathlessness can also occur during panic attacks. A clinician uses the full pattern to decide whether examination or tests are needed.
Discuss frequent or new symptoms even if perimenopause seems likely. A review is especially useful when treatment has not helped, symptoms change substantially, or you have side effects. NICE recommends reviewing menopause treatment at about three months after starting and annually thereafter, sooner when needed.
