This topic is about managing an adhesive allergy when using the Hollister 2-piece colostomy system. The person found a secure appliance but developed a skin allergy to the adhesive on the wafer. Their stoma nurse suggested cutting away all the adhesive, but this made the pouch unstable. They are looking for practical ways to keep the system secure without triggering the allergy.

Here are some helpful suggestions:

1. Create a barrier between the skin and the wafer:
- Use Nexcare Tegaderm or Sure Seals over the skin around the stoma before applying the appliance.
- Be cautious with off-brand Tegaderm as it might cause rashes for some.
- Consider using Brava full-size protective sheets or Brava barrier cream under the flange.

2. Remove the Hollister tape border and secure with hypoallergenic tapes:
- Trim off the Hollister tape border and use 3M Micropore paper tape to secure the wafer.
- Medipore tape or HyMax waterproof tape can be alternatives, but avoid Medipore’s woven version if it causes irritation.

3. Switch to different adhesive formulas or non-adhesive systems:
- Try Hollister wafers with no tape border, such as all CeraPlus or all Flextend.
- ConvaTec SureFit Moldable wafers might help reduce reactions and leaks.
- Nu-Hope Labs offers non-adhesive pouching systems that use belts instead of sticky flanges.
- If irritation occurs, consider rotating to another brand like Coloplast or ConvaTec until the skin calms down.

4. Control rashes, fungal issues, and itching:
- Apply Nystatin powder to irritated skin, seal with an adhesive spray, and then apply the wafer.
- For severe irritation, use prescription-strength steroid or antifungal creams briefly, then wash off before pouching.
- Cavilon no-sting barrier film wipes can provide an extra seal over powder.
- Diluted tea-tree-oil wipes, calamine lotion, gel ice packs, Benadryl, or Flonase sprays can help soothe inflammation or itching.

5. General skin-care and wear-time tips:
- Change appliances every 2–3 days and keep the area dry to reduce reactions.
- Allow an hour of "air time" between changes when possible.
- Trial and error may be necessary; consulting a dermatologist for patch testing and prescription options can be beneficial.
