This topic is about a possible issue with a batch of Hollister Moderma Flex convex pouches, which are causing unexpected leaks and severe skin irritation for some users. Here are some helpful insights and advice shared by others who have experienced similar issues:

1. If you suspect a bad batch, report it directly to Hollister. They often replace faulty products, send emergency supplies, and may ask for the defective items back for testing.

2. Some users have experienced problems with Hollister products, such as flanges not sticking, leaking filters, and weak Velcro closures on drainable pouches.

3. If you have persistent adhesion problems, consider checking for health issues like low potassium or kidney problems, as these can affect how well the adhesive works.

4. To protect your skin when dealing with leaks, clean the area with mild soap, dry it thoroughly, dust lightly with stoma powder, and apply a single layer of skin prep before attaching the appliance. Once your skin heals, you might skip the skin prep, as it can reduce wear time.

5. For barrier rings like Adapt or Eakin seals, warm the ring with a hairdryer for about 20 seconds, mold it to fit snugly against the stoma, and ensure no skin is exposed. You can apply the ring directly to the skin or the flange, but avoid using skin prep under the ring to prevent erosion.

6. Some members have found that using these techniques can extend the wear time of Hollister products to 5–7 days, changing only the pouch every 2–3 days.

7. Additional adhesion aids include flange extensions, medical tape, and support belts like Nu Hope or Stealth.

8. For very liquid output, such as from a high-fluid ileostomy, adding gelling sachets inside the pouch can help thicken the contents and reduce leaks, especially at night.

9. If you're considering trying other systems, some users have had positive experiences with Convatec moldable Durahesive wafers, Coloplast Sensura, Dansac, and Coloplast two-piece systems with mechanical snap-locks.

10. Keep your product boxes separate and note the lot numbers to quickly identify any defective batches.
