Histamine-Driven DIY Allergy Cocktail Gains Traction for Perimenopause
Some women are using a DIY mix of Allegra (an antihistamine) and Pepcid AC (famotidine) to ease perimenopause symptoms like hot flashes and mood swings, based on a biological link between estrogen and histamine. While there is some biology to support the approach, there’s a lack of robust clinical data and long‑term safety information, and experts caution the combination could mask underlying conditions such as endometriosis or thyroid disorders, underscoring the need for proper medical evaluation and patient advocacy.
