If you're dealing with a red, itchy rash under your stoma wafer seal and tape, you're not alone. Many people experience this and are looking for ways to relieve the discomfort while ensuring their appliance stays in place. Here are some helpful tips and remedies that might work for you:

1. **Consult a Professional**: Before trying any treatment, it's a good idea to see a stoma nurse, general practitioner, dermatologist, or allergist. They can help determine if your rash is due to irritation or a fungal infection like thrush or candida.

2. **Calamine Lotion**: This is a popular choice for quick itch relief. Apply it to clean, dry skin around your stoma and let it dry completely before putting on your wafer.

3. **Antifungal Options**:
- You can use over-the-counter antifungal powders like Zeasorb-AF or any athlete’s-foot powder in a yellow bottle. Lightly dust it on the rash, blow off any excess to avoid caking, and then apply your wafer.
- If your rash is diagnosed as candida, standard topical antifungal creams can be used, but be aware that they might affect how well your wafer sticks.

4. **Karaya Powder**: This is a soothing, absorbent barrier powder that can be applied to moist, irritated skin before you put on your pouching system.

5. **Aloe Vera**: If you have a fresh aloe vera plant, you can slice open a leaf and apply the inner gel directly to the rash. Let it air-dry completely and don't rinse it off before resealing your appliance. Many people find it helps with healing and doesn't interfere with adhesion.

6. **Application Technique**: After using any powder, lightly pat or dab the area with a skin-prep or adhesive-prep wipe to set the powder. Blow dry the area, then attach your one- or two-piece system. This can help maintain wear time and reduce itching.
