A few weeks ago, I bought something I never imagined I’d own at 48 years old: a wedge pillow.
When my middle son saw it sitting on my bed, he couldn’t resist:
“Mom… aren’t those for old people?”
Apparently, I’ve reached the stage of life where sleeping slightly propped up sometimes feels pretty wonderful.
Like many women in perimenopause, I’ve noticed symptoms that aren’t necessarily dramatic enough to feel like a medical crisis, but are noticeable enough to affect how I feel. One of mine has been what I can only describe as a “sour stomach” that seems to show up more often during the luteal phase of my cycle. Sometimes it feels like reflux; sometimes it’s simply discomfort when I lie flat.
The wedge pillow has helped.
Around the same time, I started hearing conversations about women using Pepcid (famotidine) and Zyrtec (cetirizine) during perimenopause for symptoms ranging from reflux and poor sleep to hot flashes and brain fog.
As a registered dietitian who works with women through perimenopause and menopause, I wanted to know: What does the evidence actually say?
Why Can Perimenopause Affect Digestion?
One of the biggest surprises for many women is realizing that perimenopause isn’t just about periods, hot flashes or night sweats.
Estrogen receptors are found throughout the body, including the brain, bones, bladder, skin and digestive tract. As estrogen and progesterone begin fluctuating, some women notice changes that extend well beyond their reproductive system.
That can include digestive symptoms during perimenopause, such as:
- Bloating
- Constipation or diarrhea
- Nausea
- Heartburn or reflux
- Changes in food tolerance
There may be several reasons for these changes, including effects on gastrointestinal motility, sensitivity within the digestive tract and the function of the lower esophageal sphincter—the muscle that helps keep stomach contents from moving back into the esophagus.
Hormones may also interact with histamine, which brings us to the Pepcid and Zyrtec conversation.
What Does Histamine Have to Do With Perimenopause?
Most of us associate histamine with allergies, but histamine has several jobs in the body. It helps regulate stomach acid production, plays a role in wakefulness and interacts with estrogen.
Pepcid and Zyrtec work on two different histamine receptors:
- Zyrtec blocks H1 receptors, which are involved primarily in allergic responses.
- Pepcid blocks H2 receptors and reduces stomach acid production.
We also know that estrogen can influence mast cells, the immune cells that release histamine. That has led to interest in whether changing hormone levels during perimenopause could influence histamine-related symptoms such as flushing, headaches, sleep disruption or digestive symptoms.
It’s an interesting biological hypothesis.
But an interesting hypothesis isn’t the same thing as an effective treatment.
Do Pepcid and Zyrtec Help Perimenopause Symptoms?
Right now, we don’t have good clinical evidence showing that taking Pepcid and Zyrtec together improves hot flashes, brain fog, poor sleep or other common symptoms of perimenopause.
That doesn’t necessarily mean the combination doesn’t help some women. It means we don’t yet know.
This is an important distinction in women’s health, where emerging treatments and wellness trends often travel faster than the research.
There is a difference between:
“This makes biological sense.”
and
“This has been shown to work.”
If you’re considering either medication specifically for perimenopause symptoms, it’s worth discussing the potential benefits and risks with your healthcare provider rather than assuming that a popular combination is appropriate for everyone.
What Can Help With Reflux During Perimenopause?
If reflux or nighttime stomach discomfort has become part of your perimenopause experience, start with the basics.
Strategies that may help include:
- Elevating your upper body while sleeping
- Avoiding large meals close to bedtime
- Spending some time upright after dinner before lying down
- Noticing whether alcohol worsens symptoms
- Identifying individual foods that consistently trigger reflux
For occasional symptoms, medications such as calcium carbonate (Tums) or an H2 blocker such as famotidine (Pepcid) may also be useful when appropriate.
Persistent reflux, however, deserves a conversation with your healthcare provider, especially if you’re having symptoms more than twice a week, difficulty swallowing, unexplained weight loss, black stools, vomiting blood, chest pain or symptoms that regularly wake you at night.
Nutrition During Perimenopause Is About More Than Weight
One reason I think conversations like this matter is that women are often told to expect a long list of symptoms during perimenopause without being given much help navigating them.
And nutrition during perimenopause shouldn’t simply become another conversation about eating less or trying harder to lose weight.
This stage of life is an opportunity to look at the bigger picture: digestive health, muscle and bone health, cardiovascular health, sleep, energy, body composition, fueling and your overall relationship with food.
Sometimes the answer is surprisingly simple like my wedge pillow.
Sometimes it’s adjusting meal timing or identifying foods that aren’t sitting as well as they used to.
Sometimes it’s talking with your physician about medication or menopause hormone therapy.
And sometimes it’s taking a closer look at your nutrition to make sure the way you’re eating still supports what your body needs now.
At McDaniel Nutrition Therapy, our registered dietitians work with women navigating perimenopause, menopause and midlife health. We can help you sort through the nutrition noise, understand what may be contributing to your symptoms, and develop an individualized nutrition plan that supports your health and quality of life.
Because feeling different during perimenopause doesn’t mean you simply have to put up with feeling lousy.
And yes, sometimes a wedge pillow really does earn its place on the bed.
