Quillaia and Beclomethasone

Here is the interaction we found between these two, with the evidence behind it.

Moderate

IMMUNOSUPPRESSANTS

Why this applies to Beclomethasone

Beclomethasone falls under IMMUNOSUPPRESSANTS — the group Quillaia interacts with.

Theoretically, concomitant use of quillaia with immunosuppressant drugs might decrease the effectiveness of these drugs.
In vitro research shows that some quillaia constituents have immunostimulant effects.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the idea behind this pairing. Lab studies suggest some of the saponins in quillaia may gently stimulate the immune system. Since beclomethasone is an inhaled steroid that works by calming immune-driven swelling and irritation in your airways, there's a theoretical worry that quillaia could nudge in the opposite direction and slightly blunt how well your inhaler controls your asthma. If that happened, you might notice more wheezing, coughing, or chest tightness.

I want to be honest though: this is theoretical only, based on test-tube research, not on real people taking these together. The tiny amounts of quillaia used to make foods and drinks foam are very unlikely to matter. Concentrated herbal doses are the bigger question mark. If you rely on beclomethasone daily, just check with your pharmacist or doctor before adding a quillaia supplement.

From our pharmacist’s overview on the Beclomethasone page

“Most people on beclomethasone (Beclovent, Vanceril) use it daily to keep asthma or nasal allergies quiet, and plenty also take herbal products, which is where this list earns real caution. Of the 202 ingredients on this page, four rate major, and those deserve your attention ahead of everything else.”

About Quillaia

What is Quillaia?

  • Cough and chest congestion
  • Foaming agent in beverages
  • Vaccine adjuvant (in pharmaceutical manufacturing)
  • Washing and cleansing (traditional soap)
  • Skin conditions

Quillaia (soap bark tree) is a plant whose bark contains foaming compounds called saponins, and it is widely used as an emulsifier in foods and drinks. As a supplement or herbal remedy its benefits are not well proven, and large amounts can be irritating or toxic, so it should be used cautiously and only as directed.

About Beclomethasone Oral Inhalation

What Is Beclomethasone Oral Inhalation Used For?

Brand names: Beclovent, Vanceril

Beclomethasone dipropionate HFA inhalation aerosol (brand: Qvar Redihaler) is used for the ongoing, daily management of asthma in adults and children 5 years of age and older. It is a preventive (maintenance) therapy — not a rescue inhaler — meaning it helps control asthma over time rather than treating sudden symptoms.

Important: Qvar Redihaler is not for the relief of sudden asthma attacks or acute bronchospasm. Always keep a separate fast-acting (rescue) inhaler on hand for those moments.
