My biggest ostomy complaint has been smell. Yes, I know. Gross. But poop stinks. And, having to empty in public all the time, I got really frustrated. So, I did some research. There's an over-the-counter pill called Devrom you can buy. It's an internal deodorant. Here's what the description says:
DEVROM® effectively treats embarrassing malodor from flatulence (gas) and stool. FDA approved and available without a prescription. A trusted product for over 40 years. Devrom is an internal deodorant that safely and effectively deodorizes embarrassing flatulence and stool odor. For oral use. Chewable tablets. Bismuth subgallate formula provides immediate odor control from ostomies and fecal incontinence.
I buy it on Amazon. Best $20 I've ever spent. They taste like banana runts. I take 1-2 a day, depending on what I'm eating. For example, if I eat fish or lots of veggies, I take 2. If it's a normal, carb-loading day full of potato skins and Eggo waffles, I only take 1.
I kid you not, these are a total life changer.
Of course, consult with your doctor before adding something to your medicine cabinet.
