Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist with Duavee, which pairs conjugated estrogens with bazedoxifene to ease hot flashes and protect your bones after menopause. The concern on file is mostly a theoretical one: in large, concentrated supplement doses, pleurisy root might bump up against your hormone therapy and could, in theory, blunt how well it works. That might look like hot flashes creeping back or less benefit for your bones over time.

I want to be honest, though. This is based on how the plant might behave, not on real-world studies, so the actual risk is low. The bigger issue is that pleurisy root contains naturally heart-active (cardiac glycoside) compounds and can be toxic, so I'd steer clear of it regardless. Please run it by your pharmacist or doctor before trying any.

About Pleurisy Root

What is Pleurisy Root?

  • Respiratory congestion
  • Pleurisy and chest discomfort
  • Coughs and bronchitis
  • Promoting sweating during fevers
  • Loosening mucus

Pleurisy root is the dried root of Asclepias tuberosa (butterfly weed), a plant used in traditional North American and herbal medicine mainly for respiratory complaints. There is very little modern scientific evidence that it works for any condition, and it contains compounds that can be toxic, so caution is strongly advised. Pregnant and breastfeeding people should avoid it, and anyone considering it should check with a pharmacist or doctor first.

About Estrogen and Bazedoxifene

What Is Estrogen and Bazedoxifene Used For?

Brand name: Duavee

  • Estrogen and bazedoxifene tablets are used to treat hot flashes (sudden feelings of warmth, especially in the face, neck, and chest) in women who are experiencing menopause (stage of life when menstrual periods become less frequent and stop and women may experience other symptoms and body changes). Estrogen and bazedoxifene tablets are also used to prevent osteoporosis (condition in which the bones become thin and weak and break easily) in women who have undergone menopause. Estrogen is in a class of medications called hormones and bazedoxifene is in a class of medications called estrogen agonist–antagonists. Estrogen works by replacing estrogen that is normally produced by the body. Bazedoxifene is used to block the action of estrogen on the lining of the uterus, decreasing the risk of overgrowth that may lead to cancer.
