HelloPharmacist Scorecard of Pepto Herbal Blends Peppermint & Caraway by Pepto Bismol
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
This product contains 2 active herbal ingredients: peppermint aerial oil and caraway seed oil, both concentrated botanical extracts meant to settle the stomach. The capsule also holds several inactive ingredients — sunflower oil, gelatin, glycerin, and other binders and thickeners — that help deliver the oils.
Does it work?
Strong evidence
Peppermint is likely effective for irritable bowel syndrome (IBS) and possibly effective for indigestion, nausea from chemotherapy, colon spasms before medical imaging, and side effects from endoscopy. Caraway is possibly effective for indigestion but has insufficient evidence for amenorrhea, asthma, constipation, or gas.
The product pairs them for digestive comfort, though the combined effect isn't separately rated in the data we hold.
How safe is it?
Well-documented data
Orally, peppermint oil is generally well tolerated, though side effects in trial participants included belly pain, anal burning, belching, diarrhea, dry mouth, heartburn, nausea, and vomiting. Rare allergic reactions — including anaphylaxis with throat swelling and breathing trouble — have been reported, and there's one documented case of an allergic reaction when peppermint and caraway were used together in someone with asthma.
For caraway combined with peppermint, substernal burning, belching, nausea, and vomiting have been noted, though it's unclear which ingredient caused them. Peppermint is rated likely safe in pregnancy.
Caraway is rated possibly unsafe in pregnancy, and safety data during breastfeeding for both ingredients are limited. If you're pregnant or nursing, talk to your doctor or pharmacist before taking this product.
Meds to double-check
Moderate interaction found
Before taking this product, check your medications if you take blood pressure drugs or other medicines metabolized by CYP3A4, CYP2C9, or CYP2C19 (peppermint); diabetes medications, sleeping pills or tranquilizers, water pills, or lithium (caraway); or tuberculosis drugs like isoniazid or rifampin (caraway). If you're unsure whether your drug falls into these categories, use the checker on this page.
The bottom line
Scorecard at a glanceFully disclosed formula with clinical evidence supporting its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Pepto Herbal Blends Peppermint & Caraway by Pepto Bismol Drug Interactions
HelloPharmacist Interaction Report
Pepto Bismol Herbal Blends Peppermint & Caraway contains two herbal oils that interact with medications.
The most serious concerns come from peppermint, which theoretically may raise the levels of drugs your liver breaks down — specifically those metabolized by three major enzyme systems (CYP3A4, CYP2C9, and CYP2C19). In one clinical study, peppermint oil slowed the breakdown of felodipine, a blood pressure medication.
The same enzyme inhibition could affect immunosuppressants like cyclosporine. All of these peppermint interactions are rated Moderate.
Read the full breakdown — every affected drug type, severity by severity
Caraway seed oil brings its own risks. It may lower blood sugar (hypoglycemia) when combined with diabetes medications, make CNS depressants like sleeping pills or sedatives stronger, interact with diuretics (water pills) and increase potassium loss, and theoretically affect lithium levels by reducing how your kidneys clear it — all Moderate severity.
Additionally, caraway may increase blood levels of tuberculosis drugs (isoniazid, rifampin, pyrazinamide), though these are Minor interactions not yet reported in humans.
Neither interaction has been well tested in real people, but the theoretical risks are real enough to warrant checking. Altogether, these interactions span 1,051 individual medications.

For each ingredient in Pepto Herbal Blends Peppermint & Caraway with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
Peppermint Aerial Oil
Cyclosporine (Neoral, Sandimmune)
Theoretically, peppermint oil might increase the levels and adverse effects of cyclosporine.
In animal research, peppermint oil inhibits cyclosporine metabolism and increases cyclosporine levels. Inhibition of cytochrome P450 3A4 (CYP3A4) may be partially responsible for this interaction. An interaction between peppermint oil and cyclosporine has not been reported in humans.
Cytochrome P450 2C19 (Cyp2C19) Substrates
Theoretically, peppermint might increase the levels of CYP2C19 substrates.
In vitro research shows that peppermint oil inhibits CYP2C19. So far, this interaction has not been reported in humans.
Cytochrome P450 2C9 (Cyp2C9) Substrates
Theoretically, peppermint might increase the levels of CYP2C9 substrates.
In vitro research shows that peppermint oil inhibits CYP2C9. So far, this interaction has not been reported in humans.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, peppermint might increase the levels of CYP3A4 substrates.
Clinical research in healthy volunteers shows that a single dose of peppermint oil 600 mg inhibits CYP3A4 enzymes and increases the AUC of felodipine, a CYP3A4 substrate. However, in vitro research suggests that peppermint oil only inhibits CYP3A4 at very high concentrations.
Cytochrome P450 1A2 (Cyp1A2) Substrates
Theoretically, peppermint might increase the levels of CYP1A2 substrates.
In vitro and animal research shows that peppermint oil and peppermint leaf inhibit CYP1A2. However, in clinical research, peppermint tea did not significantly affect the metabolism of caffeine, a CYP1A2 substrate. It is possible that the 6-day duration of treatment may have been too short to identify a difference.
Caraway Seed Oil
Antidiabetes Drugs
Theoretically, caraway might increase the risk of hypoglycemia when used with antidiabetes drugs.
Animal research suggests that caraway can reduce blood glucose levels. Monitor blood glucose levels closely. Medication dose adjustments may be necessary.
Cns Depressants
Theoretically, caraway might increase the effects and adverse effects of CNS depressants.
Animal research suggests that (S)-(+)-carvone, a major constituent of caraway seed extract, has sedative effects.
Diuretic Drugs
Theoretically, caraway might increase the risk of hypokalemia when used with diuretics that deplete potassium.
Animal research suggests that a single dose of caraway fruit extract can promote diuresis and increase the urinary excretion of sodium and potassium. However, sub-chronic use of caraway fruit extract does not seem to significantly increase potassium excretion, although urine output continues to be increased for up to 6 days.
Lithium
Theoretically, caraway might reduce excretion and increase levels of lithium due to diuretic effects.
Animal research suggests that caraway fruit extract has diuretic properties.
Isoniazid
Theoretically, caraway might increase the effects and adverse effects of isoniazid.
Animal research suggests that a specific fraction of caraway seed extract (CC-1a) can increase plasma levels of isoniazid when administered concomitantly. This interaction has not been reported in humans.
Pyrazinamide
Theoretically, caraway might increase the effects and adverse effects of pyrazinamide.
Animal research suggests that a specific fraction of caraway seed extract (CC-1a) can increase plasma levels of pyrazinamide when administered concomitantly. This interaction has not been reported in humans.
Rifampin (Rifadin)
Theoretically, caraway might increase the effects and adverse effects of rifampin.
Animal research suggests that a specific fraction of caraway seed extract (CC-1a) can increase plasma levels of rifampin when administered concomitantly. This interaction has not been reported in humans.
