How do I manage my menopause-related insomnia at 45?

Question

Hi doctor,

I am a 45-year-old female and have been struggling with sleep for the past year. I fall asleep easily but wake up at 2 to 3 a.m., drenched in sweat, and cannot get back to sleep. My periods are irregular, follicle-stimulating hormone is 34 mIU/mL, and I am more anxious than usual. Is this insomnia related to perimenopause? Should I try hormone replacement therapy or melatonin first? I just want restful sleep again.

Please guide.

Hi,

I am glad you chose icliniq.com for your medical-related queries.

I understand your concern.

So what you are describing is very consistent with perimenopausal insomnia, and the combination of early morning awakenings, night sweats, irregular periods, and elevated follicle-stimulating hormone (34 mIU/mL or milli-international units per milliliter) strongly suggests you are in the menopausal transition.

During this time, fluctuating and declining estrogen and progesterone levels can disrupt your body’s temperature regulation, stress response, and sleep-wake cycle. This kind of sleep disruption, especially waking between 2 and 4 a.m. with sweats and anxiety, is very common in perimenopause.

I suggest the following treatments to help you:

Hormone replacement therapy (HRT): This is the most effective option when symptoms like night sweats and sleep disruption are clearly tied to hormonal shifts. Estrogen (sometimes combined with progesterone) can significantly reduce vasomotor symptoms and improve sleep quality.
Melatonin: It sometimes helps with sleep onset and mild circadian rhythm issues, but it is unlikely to resolve hormonally driven awakenings or night sweats. If you are not ready for hormone replacement therapy, a low dose (0.3 to 1 milligram) of melatonin may be worth trying initially. However, if you begin hormone replacement therapy, you usually do not need sleep medication because your sleep will be regulated.
Non-hormonal alternatives: Selective serotonin reuptake inhibitors and serotonin-norepinephrine reuptake inhibitors (such as Venlafaxine or Escitalopram) can reduce hot flashes and improve sleep for some women.

Given your age and symptoms, I suggest starting hormone replacement therapy, especially if you are otherwise healthy and within ten years of your final menstrual period. Hormone replacement therapy not only improves sleep but also supports mood, bone health, and overall quality of life during this transition.

I hope this has helped you. Please feel free to reach me again in case of further queries.

Thank you.
