Fermented Milk and Ciclesonide

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

Moderate

IMMUNOSUPPRESSANTS

Why this applies to Ciclesonide

Ciclesonide falls under IMMUNOSUPPRESSANTS — the group Fermented Milk interacts with.

Theoretically, fermented milk might decrease the effects of immunosuppressants.
Clinical research suggests that fermented milk has 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 one: fermented milk contains live cultures that may gently nudge the immune system to be a little more active. Ciclesonide, on the other hand, is an inhaled steroid that works by calming inflammation in your airways. So in theory, something that revs the immune response could work against what ciclesonide is trying to do.

In real life, I wouldn't lose sleep over this. This warning is purely theoretical, based on how things might behave rather than actual cases. Ciclesonide also works mostly right in your lungs with very little reaching the rest of your body, so a glass of kefir or a cup of yogurt is very unlikely to weaken your asthma control. If you notice more wheezing or chest tightness, mention it to your pharmacist or doctor.

From our pharmacist’s overview on the Ciclesonide page

“Ciclesonide (Alvesco, Omnaris, Zetonna) is a corticosteroid for asthma and nasal allergies, and even though it is inhaled rather than swallowed, its supplement list warrants genuine care. The body clears it through the CYP3A4 enzyme, and 121 of the 166 ingredients on file nudge that pathway one way or the other.”
