That's a really valid concern, and you're not alone in noticing this. Being on Bimzelx (bimekizumab) — which works by blocking IL-17A and IL-17F to reduce HS inflammation — can lower your body's ability to fight off fungi that naturally live on the skin. This makes fungal infections a known potential side effect of this type of treatment.
Other myHSteam members have shared similar experiences, including one who noted: "I have contracted a fungal infection from some of my medication. It's very sore and just as weepy and stinky as HS." While fungal infections are more commonly discussed in areas like the feet, they can show up in other places too — including skin folds and areas prone to moisture, like the collarbone and upper back.
Here are some important steps to consider:
- Talk to your dermatologist or doctor about the fungal symptoms you're experiencing, especially since you're on a biologic
- Mention the location (collarbone and upper back) specifically, as your doctor may want to examine or swab the area
- Ask about treatment options, which can include topical antifungal creams or other medications
- Don't adjust or stop Bimzelx on your own — your doctor may consider tweaking your treatment plan if fungal infections become frequent
It's really important to get a proper diagnosis so the right treatment can be prescribed. Fungal infections are manageable, but they do need attention — especially when you're on a medication that affects your immune response.
