Probiotics and Sulconazole

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

Minor

ANTIFUNGALS

Why this applies to Sulconazole

Sulconazole falls under ANTIFUNGALS — the group Probiotics interacts with.

Theoretically, taking antifungals with certain probiotics might decrease the effectiveness of probiotics.
Some probiotics such as Saccharomyces boulardii are fungi. Therefore, simultaneously taking antifungals might kill a significant number of these organisms.
Severity Minor 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 good news: this is a very mild, mostly theoretical concern, and it goes the opposite direction of what most people worry about. Sulconazole won't change because of your probiotic. Instead, the probiotic could lose a little punch. Sulconazole (Exelderm) is an antifungal cream you rub on the skin for things like athlete's foot, jock itch, and ringworm, so very little of it gets into your body.

The only real wrinkle is if your probiotic contains a yeast, like Saccharomyces boulardii. Since antifungals fight fungi, an antifungal could in theory knock out some of those friendly yeast cells. With a skin cream that stays on the skin, this overlap is minimal. If you take a yeast-based probiotic by mouth, just ask your pharmacist about spacing them out.

From our pharmacist’s overview on the Sulconazole page

“Sulconazole (Exelderm) is a topical antifungal cream for skin infections like ringworm and jock itch, yet its interaction list warrants real care, not a quick skim. The single major-rated entry, activated charcoal, can pull medications out of the body and lower their levels regardless of how the drug was given, and it is the one to und…”

About Probiotics

What is Probiotics?

  • Digestive health and regularity

Probiotics are live 'friendly' microbes that may help certain digestive conditions, such as antibiotic-associated diarrhea and some cases of IBS, though benefits depend heavily on the specific strain and dose. They are generally well tolerated for healthy people but should be used with caution by those with serious illness or weakened immune systems.
