HelloPharmacist Editorial Team Bottom Line
Bismuth subsalicylate is a well-known OTC option for short-term relief of diarrhea, traveler's diarrhea, and upset stomach. It should not be used in children or teens with chicken pox or flu-like illness due to the risk of Reye's syndrome, and people with salicylate allergies or ulcers should avoid it. Don't use it for more than 2 days — if symptoms persist, check in with your doctor.

📖 Bismuth Subsalicylate: Patient Information Guide

A plain-language walkthrough of Bismuth Subsalicylate — what it treats, how it works, how it’s taken, side effects, warnings and interactions. Tap any section to expand it.

🎯What it's used for▾

Bismuth subsalicylate is an over-the-counter medicine that treats a range of common digestive problems. It is available under many brand names and in several forms.

  • Diarrhea
  • Traveler's diarrhea
  • Upset stomach due to overindulgence in food and drink
  • Heartburn
  • Indigestion
  • Nausea
  • Gas
  • Belching
  • Fullness
💊How it's taken▾

Bismuth subsalicylate comes in several oral forms: chewable tablets, capsules (including softgels), liquid solutions, and oral suspensions. It is taken by mouth every 30 minutes to 1 hour as needed, depending on the symptom and the specific product.

  • Chewable tablets (such as Pepto Bismol and Kroger Stomach Relief): chew completely or dissolve in the mouth before swallowing — do not swallow whole
  • Liquid and suspension products (such as Soothe and Stomach): always shake well before use and measure with the dosing cup that comes with the product — do not use any other measuring device
  • Do not exceed 8 doses in any 24-hour period, and do not use for more than 2 days for diarrhea
  • Drink plenty of clear fluids while using this medicine to prevent dehydration

Always follow the directions on your specific product label and check with your pharmacist if you are unsure.

🤒Side effects — in detail▾

Bismuth subsalicylate has a well-known and harmless side effect that surprises many people:

  • Darkening of the stool — your stool may turn black or very dark; this is temporary and harmless
  • Darkening of the tongue — a temporary dark discoloration that goes away on its own

Stop use and contact a doctor right away if you develop ringing in the ears or loss of hearing, or if your symptoms get worse or do not improve within 2 days.

⚠️Warnings & precautions▾

Reye's syndrome: This is the most critical warning. Children and teenagers who have or are recovering from chicken pox or flu-like illness must NOT use this product. Bismuth subsalicylate contains a salicylate, and salicylates have been linked to Reye's syndrome — a rare but life-threatening illness affecting the brain and liver. Watch for behavior changes combined with nausea and vomiting, and call a doctor immediately if these occur.

  • Do not use if you are allergic to salicylates or aspirin
  • Do not use if you have an ulcer, a bleeding problem, or bloody or black stools (unrelated to the medicine)
  • Ask a doctor before use if you have fever or mucus in the stool
  • Stop use and call a doctor if symptoms worsen, diarrhea lasts more than 2 days, or ringing in the ears occurs
  • Ask a health professional before use if you are pregnant or breastfeeding
🔀What it interacts with▾

Because bismuth subsalicylate contains a salicylate (similar to aspirin), it can interact with several types of medication. Check with your doctor or pharmacist before taking it if you use any of the following:

  • Blood thinners (anticoagulants) — salicylates can increase bleeding risk when combined with these drugs
  • Diabetes medications — salicylates may affect blood sugar control
  • Gout medications — salicylates can interfere with how these drugs work
  • Arthritis medications — some arthritis drugs are also salicylates; combining them raises the risk of side effects
  • Other salicylate products, including aspirin — do not use together; doubling up on salicylates increases the risk of side effects

This is not a complete list of interactions. Always talk with your doctor or pharmacist before starting, stopping, or changing any medication.

📋Before taking it▾
  • Salicylate or aspirin allergy: Do not use this product if you are allergic to aspirin or any other salicylate
  • Ulcer or bleeding problem: Do not use if you have an active ulcer, a bleeding disorder, or stools that are already bloody or black
  • Children and teenagers with viral illness: Do not give to children or teens recovering from chicken pox or flu-like symptoms — risk of Reye's syndrome
  • Children under 12: Ask a doctor before use
  • Fever or mucus in stool: Ask a doctor before use — these symptoms may point to a more serious infection
  • Pregnancy and breastfeeding: Ask a health professional before use
  • Medications for blood thinning, diabetes, gout, or arthritis: Ask a doctor or pharmacist before combining with bismuth subsalicylate
🚑If you take too much▾

If you think someone has taken too much bismuth subsalicylate, get medical help or contact Poison Control immediately at 1-800-222-1222. Act quickly — do not wait for symptoms to appear.

📦How to store it▾

🩺 Pharmacist Counseling Corner

Quick, plain-English answers to the questions patients ask most about Bismuth Subsalicylate — the kind of thing our pharmacy team would talk through with you at the counter.

What is bismuth subsalicylate actually used for? ▾
It's used to calm a range of stomach and digestive problems — things like diarrhea, traveler's diarrhea, heartburn, indigestion, nausea, gas, belching, and that uncomfortable over-full feeling after eating or drinking too much. It's the active ingredient in well-known brands like Pepto Bismol and Kaopectate.
Why did my stool turn black after taking this? Should I be worried? ▾
Don't panic — that's actually a very common and completely harmless side effect of bismuth subsalicylate. The medicine can temporarily turn your stool and even your tongue a dark or grayish-black color. It goes away on its own once you stop taking the medicine. That said, if your stool was already black or bloody before you started taking it, that's a different story — don't use this product and see a doctor.
Can I give this to my child who has the flu? ▾
No — this is a really important one. Children and teenagers who have or are recovering from the flu, chicken pox, or any flu-like illness should not take bismuth subsalicylate. It contains a salicylate, which has been linked to a rare but serious condition called Reye's syndrome that affects the brain and liver. For kids under 12 in general, always check with a doctor before giving this medicine.
How long can I take this before I should see a doctor? ▾
For diarrhea, use it only until the diarrhea stops — and no longer than 2 days. If your diarrhea lasts more than 2 days, or if your symptoms get worse, it's time to call your doctor. Same goes if you notice ringing in your ears or any hearing changes — stop the medicine and check in with a healthcare provider.
I take aspirin and a blood thinner. Is this safe for me? ▾
You'll want to check with your doctor or pharmacist before taking bismuth subsalicylate if you're on a blood thinner or already taking aspirin. This medicine contains a salicylate — similar to aspirin — so combining it with other salicylates or blood-thinning drugs can raise your bleeding risk. It can also interact with medications for diabetes, gout, and arthritis, so mention those too.
Can I take this if I'm pregnant or breastfeeding? ▾
The label says to ask a health professional before using bismuth subsalicylate if you are pregnant or breastfeeding. Don't skip that step — it's worth a quick call to your OB or midwife to make sure it's appropriate for your situation.
Is Bismuth Subsalicylate available over the counter? ▾
Yes — Bismuth Subsalicylate is available over the counter (without a prescription) in at least some forms, according to its FDA labeling. Follow the package directions and ask your pharmacist if you're unsure which product is right for you.
When was Bismuth Subsalicylate first available? ▾
Bismuth Subsalicylate has been available in the United States since at least 1986, based on FDA approval history (Drugs@FDA) and product marketing records.
Who makes Bismuth Subsalicylate? ▾
Bismuth Subsalicylate is supplied by 156 manufacturers listed in the FDA NDC Directory, including The Procter & Gamble Manufacturing Company, Rite Aid Corporation, Strategic Sourcing Services LLC.

📈 How widely Bismuth Subsalicylate is used

A general measure of how commonly Bismuth Subsalicylate is prescribed, based on Medicaid — one of the largest public drug programs. The figure below is prescriptions filled in Q1–Q4 2025, summed across every form and brand of the drug.

Think of this as a proxy for how widely Bismuth Subsalicylate is used, drawn from freely available public data. Medicaid is just one program — these numbers don’t include Medicare, other government coverage, or commercial and cash-pay prescriptions, so real-world use is higher than what’s shown here.

Shares are of the Medicaid prescriptions shown here. Product grouping follows RxNorm (the National Library of Medicine’s drug terminology), so “one product” means one strength & dosage form regardless of manufacturer. Dollar figures are gross Medicaid reimbursement before mandatory rebates — rebates (often large, especially for brand-name drugs) are confidential, so actual net cost to Medicaid is lower than shown.

A general popularity signal; it excludes Medicare, commercial insurance and cash prescriptions, so it is not total U.S. use.

How we combine label and product data

HelloPharmacist combines public FDA and NLM records; we don’t author the underlying clinical facts. We identified 276 FDA-filed SPL label sets within the page’s selected clinical scope after exact ingredient or ingredient-combination matching and applicable route/form matching. The representative label is the starting point for the displayed reference monograph; the 12 largest stored in-scope SPL records, which may include that representative, are compared section by section, and the longest available version of each section is retained. Forms, routes, brands, labelers, product-listed strengths, and product-record counts are aggregated separately from ingredient-matched FDA NDC Directory records; package records listed above are associated with the linked SPL; and the normalized concept hierarchy comes from NLM RxNorm.

For canonical ingredient pages, bounded product-attributed indication and administration excerpts may be added to the AI evidence, and the generator is instructed to preserve available product, brand, route, and form qualifiers instead of treating one label as universal. Where a section is identified as AI-written, its plain-language text is generated from bounded label evidence. New draft drug pages remain in the admin review queue before first publication. Kroger Company is the representative DailyMed label linked for verification and dates; it is not the sole source used for the page.

This is general education, not medical advice — always consult your doctor or pharmacist about your medications and any medical condition. For the exact wording of the linked representative label, view that label on DailyMed; some displayed composite sections may come from other in-scope SPL labels.
