Coleus and Beclomethasone

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Beclomethasone

Beclomethasone falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Coleus interacts with.

Theoretically, taking coleus might decrease serum levels of drugs metabolized by CYP3A4.
In vitro research shows that coleus can activate the nuclear receptor, pregnane X receptor (PXR), which results in increased expression of CYP3A4. Although the clinical significance of this is not known, use caution when considering concomitant use of coleus and other drugs affected by these enzymes.
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. Your inhaler, beclomethasone, is partly broken down by a liver enzyme called CYP3A4. Lab studies suggest Coleus (forskolin) can nudge the body into making more of that enzyme, which in theory could clear the steroid a little faster and make it slightly less effective at calming the swelling in your airways. If that happened, you might notice your asthma is less controlled, with more wheezing, coughing, or chest tightness.

I want to keep this in perspective. This is based only on test-tube research, not on real people, so it may not matter much in everyday life, especially since beclomethasone acts mostly right in the lungs. Still, asthma control is nothing to gamble with, so check with your pharmacist or doctor before adding Coleus, and never stop your inhaler on your own.

What These Ratings Mean

Every interaction above is graded three ways — here’s the key to each label.

Severity how clinically significant the interaction is
Major

Clinically significant. Avoid the combination, or use only under close professional supervision.

Moderate

Usually worth avoiding or managing — may need monitoring, a dose change, or timing apart.

Minor

Generally not serious. Be aware of it and mention it to your pharmacist.

Likelihood how strong the evidence is that the interaction actually happens in people
  • LikelyWell-controlled human studies have demonstrated the likely existence of this interaction.
  • ProbableInteraction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • PossibleInteraction 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.
  • UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Evidence the quality of the studies behind the rating (graded A–D)
  • AHigh-quality meta-analysis (quantitative systematic review).
  • BCase-control study.
  • CConsensus.
  • DAnecdotal evidence.

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 Coleus

What is Coleus?

Coleus
  • Weight management
  • Asthma and breathing
  • High blood pressure
  • Heart conditions
  • Glaucoma (eye pressure)
  • Exercise and body composition

Coleus is a plant from the mint family whose root contains a compound called forskolin, often marketed for weight loss, asthma, and heart health. While early lab and small human studies are interesting, solid proof that Coleus supplements help any of these conditions is limited. Talk to your pharmacist or doctor before using it, especially if you have heart problems or low blood pressure.

About Beclomethasone Oral Inhalation

What Is Beclomethasone Oral Inhalation Used For?

Brand names: Beclovent, Vanceril

Beclomethasone dipropionate HFA inhalation aerosol (the oral inhaler, sold as Qvar Redihaler) is used for the long-term, preventive treatment of asthma in people 5 years of age and older.

It is not a rescue inhaler. It does not relieve sudden asthma symptoms such as shortness of breath. The nasal spray form, Qnasl, appears in the supplied label text in studies of allergic rhinitis (nasal allergy symptoms), but no approved uses for it are listed there.
