Topic Explanation
The discussion centers around an urgent issue with a colostomy barrier. The original poster experienced severe itching and discovered a rash under the barrier, which caused burning and adhesion problems. They are seeking immediate solutions available at a local drugstore to manage the rash and ensure the barrier adheres properly, as they have an appointment to attend.

Advice and Insights
1. Barrier Adhesion Solutions:
- Use medical tape around the edges of the wafer to keep it sealed.
- Consider using transparent adhesive rolls like Hypafix around the stoma before applying the wafer.

2. Skin Treatment Suggestions:
- Domeboro soak (aluminum acetate) can help dry and heal the skin. Soak a paper towel in the solution and apply it to the affected area.
- Fungal infections might be the cause; applying a fungal cream and letting it sit before cleaning and applying the barrier can help.
- Original non-fragrance Head and Shoulders shampoo can be used to clean the area.
- Boudreaux's Butt Paste diaper rash cream can be applied after cleaning with Head and Shoulders shampoo, followed by Hollister Karaya 5 powder to help the bag stick.

3. Barrier Film and Wipes:
- Use a barrier film that dries quickly to protect the skin before applying the ring.
- Cavilon swabs and spray are recommended for crusting; apply stoma powder and repeat the process a few times.
- Barrier wipes that dry and act as a protective layer can be beneficial for long-term management.

4. Additional Products and Techniques:
- Hydrocolloid Gel adhesive pads can be used for wound care and to seal out water, though caution is advised to avoid damaging the skin when removing the appliance.
- Consider using barrier strips around the new barrier for additional support.

5. Medical Consultation:
- If the rash persists, consult a doctor or ostomy nurse for a prescription, such as Nyacin powder for fungal infections or Clotrimazole cream for bacterial infections.

6. Personal Experiences and Observations:
- Over-sanitizing with hand sanitizer or soap can break down the barrier ring, leading to leaks and skin irritation.
- Identifying the root cause of the rash, whether fungal or bacterial, is crucial for effective treatment.
