Managing odor from colostomy gas and stool can be a concern for many people. If you're looking for ways to reduce or eliminate these odors, here are some suggestions and insights shared by others:

1. Hollister Products:
- M9 Deodorizer Drops, also known as M9 Lubricating Deodorizer, and Adapt Lubricant/Deodorant are popular choices. Users recommend adding several drops inside the pouch after each emptying. These products are available from Hollister, Amazon, and most ostomy-supply distributors.

2. Devrom (bismuth subgallate) Chewable Tablets:
- Many users find these tablets effective for controlling internal odors. However, there is no information provided about the dosage or whether they require a prescription.

3. Coloplast Lubricant and Deodorant:
- Similar to Hollister products, users suggest applying drops inside the pouch after every emptying to help keep odors down.

4. Breath-Mint Work-Arounds:
- Some people use peppermint Altoids, peppermint Life Savers, or Tic Tacs in the pouch. While some find these mints partially effective, others notice little effect.

These tips might help you manage odors more effectively and make your experience more comfortable.
