Parthenon Devrom Internal Deodorant Capsules — Bismuth Subgallate 200mg, FDA-Approved, Ostomy & GI Odor Control, 100 per Bottle

Works from the inside out. Eliminates odor before it leaves the body. Devrom® Internal Deodorant Capsules are an FDA-approved, over-the-counter oral medication containing 200mg bismuth subgallate — the only clinically proven internal deodorant for neutralizing odor from flatulence and stool at the source, inside the digestive tract. Unlike external sprays and pouch deodorants that manage odor after it has already formed, Devrom works systemically — bismuth subgallate binds with sulfur-containing gases in the intestinal tract during digestion, neutralizing the odor before it is passed. No perfume. No masking. The odor is chemically neutralized before it exits. Fast-acting — works almost immediately. Trusted by ostomy patients, people with fecal incontinence, bariatric surgery patients, and anyone managing chronic digestive odor. Lactose-free. Available without a prescription. Recommended by doctors, nurses, and WOCNs for over 50 years. SKU 50016. 100 capsules per bottle. Also available as chewable tablets (banana flavor).

Available SKUs

Capsules vs. Tablets: Both contain identical 200mg bismuth subgallate doses and deliver the same odor-control result. Some users report the chewable tablets act slightly faster due to earlier dissolution in the digestive tract. The capsules are preferred by patients who dislike the chewable format or the banana flavor. Both formats are lactose-free.

Product Details

Features & Benefits

• Works From the Inside — Neutralizes Odor Before It Exits — External ostomy deodorants, pouch sprays, and drops address odor after it has already formed inside the pouch. Devrom addresses the problem upstream — taken orally, the bismuth subgallate travels through the digestive tract and binds chemically with the sulfur compounds that cause the characteristic foul odor of intestinal gas and stool. The odor is neutralized within the gut before it is expelled. The result is that the output arriving in the pouch — or passed via flatulence — has significantly reduced or eliminated odor to begin with. No spray or drops can replicate this mechanism because they act on output that already contains the odor compounds. Devrom eliminates the compounds before they reach the pouch.
• FDA-Approved — Clinically Proven for Over 50 Years — Devrom is the only FDA-approved internal deodorant for malodorous flatulence. It has been used clinically and recommended by ostomy nurses, colorectal surgeons, and gastroenterologists for over 50 years. The active ingredient bismuth subgallate is a well-established pharmaceutical compound with a long safety record in clinical use. This is not a supplement or an untested remedy — it is a regulated, approved OTC drug with a documented mechanism of action.
• Recommended by WOCNs — Standard of Care for Ostomy Odor — Wound, Ostomy, and Continence Nurses (WOCNs) routinely recommend Devrom as part of ostomy odor management for patients with colostomies and ileostomies. Ileostomy output in particular contains highly active digestive enzymes and odor compounds — Devrom's internal action is especially effective for ileostomy patients whose output is most odorific. For colostomy patients, Devrom reduces stool odor that would otherwise be concentrated in the pouch between emptying intervals.
• Broad Use — Not Just for Ostomy — Devrom is appropriate for anyone managing digestive odor regardless of ostomy status. Bariatric surgery patients — particularly those who have undergone gastric bypass, duodenal switch, or biliopancreatic diversion — frequently experience malodorous flatulence as a result of altered digestion. Devrom is commonly used in this population. It is equally appropriate for patients with fecal incontinence, IBS-associated odor, or anyone for whom embarrassing digestive odor affects quality of life and confidence.
• No Prescription — Available Over the Counter — Devrom is an OTC drug. No prescription, no doctor's visit, no prior authorization required. This makes it immediately accessible for patients who need relief — and easily added to an existing supply order without clinical coordination. It can be purchased with FSA or HSA funds.
• Lactose-Free —100 Capsules per Bottle — The capsule formula is completely lactose-free — appropriate for patients with lactose intolerance or dairy sensitivity. Each bottle contains 100 capsules — at the typical starting dosage of 3 capsules per day, one bottle provides approximately a 33-day supply. Adjust dosage based on response, up to the maximum of 8 capsules per day.

Devrom Capsules vs. Devrom Chewable Tablets

Bottom line: Choose whichever format is easier to take consistently. Both deliver the same bismuth subgallate dose and the same odor-neutralizing result. Consistent daily use produces the best outcome — the format that is easiest to take is the right one.

Dosage & Usage Instructions

Recommended Dosage: Take 1–2 capsules up to four times daily. Do not exceed 8 capsules in 24 hours. Take with or without food.

Starting Recommendation: Begin with one capsule around breakfast, one around lunch, and one around dinner. Adjust upward to 2 capsules per dose if needed based on your response. Most patients find an effective dose within the first 1–3 days of use.

Important Notes:

• Bismuth subgallate may temporarily darken stool or tongue — this is normal and not harmful.
• If you take other medications, consult your doctor or pharmacist before use — bismuth compounds can interact with certain antibiotics and medications.
• Not effective against bad breath (halitosis) — Devrom acts specifically on intestinal odor, not upper GI or oral sources.
• Do not use if you have a known sensitivity to bismuth compounds.
• Consult your physician if you have kidney disease before using bismuth-containing products.
