This month we covered a practical look at using povidone-iodine as a local antiseptic for hidradenitis suppurativa (HS). The post explains how the solution can help control bacterial load, reduce drainage and odor, and support healing of small lesions. If you’re dealing with HS and want a straightforward, at-home approach to wound care, these notes are a good starting point — but they don’t replace medical advice.
Povidone-iodine is a broad-spectrum antiseptic that kills bacteria, some viruses, and fungi on contact. For HS, the idea is simple: by lowering the number of microbes in and around a nodule or tunnel, you can reduce secondary infection and inflammation that make symptoms worse. Some small case reports and clinicians’ notes show local improvement when povidone-iodine is used as part of regular wound care, but it’s not a cure for the underlying disease.
Start by washing your hands and gently cleaning the affected area with mild soap and water. Pat the skin dry. Use a cotton swab or sterile gauze to apply a small amount of povidone-iodine to the lesion — you don’t need to soak the whole area. Many people apply it once or twice a day, depending on drainage and comfort. If the area is actively draining, cover with a breathable dressing after application to protect clothing.
Keep a few safety points in mind. Povidone-iodine can stain skin and fabric. Test a tiny patch first if you’ve never used it, and stop if you see a rash or swelling. Don’t use it if you know you’re allergic to iodine. If you have thyroid disease, are pregnant, or are breastfeeding, check with a clinician before regular use. Avoid packing deep sinus tracts or using it as a substitute for surgical drainage when an abscess needs to be opened by a doctor.
Also remember that povidone-iodine can be irritating with long-term daily use on large open wounds; some clinicians prefer alternating antiseptics or using it for short periods. If lesions get worse, become more painful, show spreading redness, or you develop fever, see a healthcare provider promptly — those signs can mean a deeper infection that needs antibiotics or procedure-based care.
The November post shares user experiences, step-by-step tips, and a balanced view of when antiseptic care helps and when you need specialist treatment. If you’re experimenting with at-home measures, keep notes on what helps, stay consistent for a few weeks, and loop in your dermatologist or primary care doctor to make sure your approach fits your overall HS plan.
