HelloPharmacist Scorecard of Pepogest by Nature's Way
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
Pepogest contains one active ingredient: peppermint aerial parts oil. It also includes inactive ingredients — gelatin capsule, soybean oil, glycerin, ethylcellulose, sodium alginate, medium chain triglyceride, oleic acid, and stearic acid — which serve as fillers and binders to make the softgel.
Does it work?
Strong evidence
Peppermint oil is likely effective for irritable bowel syndrome (IBS). For indigestion (dyspepsia), nausea from chemotherapy, spasms during barium enemas, and side effects from endoscopy, the evidence rates it as possibly effective.
The research suggests it helps with certain digestive and procedure-related concerns, though the strength of evidence varies by use.
How safe is it?
Well-documented data
Peppermint oil taken by mouth is generally well tolerated. The most common side effects are abdominal pain, anal burning, belching, diarrhea, dry mouth, heartburn, nausea, and vomiting — usually mild.
Rare cases of allergic reactions, including anaphylaxis (sudden swelling of lips and throat), have been reported. Very high doses may cause chemical burns in the mouth and throat; undiluted oil should never be swallowed.
Peppermint is rated likely safe in pregnancy and lactation. That said, concentrated supplements should be used only if your provider approves, especially during pregnancy — culinary amounts in food and tea are a different story than supplement doses.
Meds to double-check
Moderate interaction found
Before taking Pepogest, check with your pharmacist if you take cyclosporine (an immunosuppressant) — peppermint oil may increase its levels and side effects. Also verify any medications metabolized by CYP3A4, CYP2C9, or CYP2C19 enzymes; peppermint oil may raise their blood levels.
Use the medication search tool on this page to check your prescriptions.
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.
Pepogest may help with IBS and indigestion. If you take cyclosporine or any drug that your liver processes, check with your pharmacist before starting it — peppermint oil can raise drug levels.
It's generally well tolerated, but very high doses or undiluted oil can irritate your mouth and throat.

Pepogest by Nature's Way Drug Interactions
HelloPharmacist Interaction Report
Pepogest by Nature's Way contains peppermint oil, which interacts with a significant number of medications through your liver's drug-processing system.
The most serious documented interaction is with cyclosporine (Neoral, Sandimmune), an immunosuppressant: peppermint oil may raise cyclosporine levels and increase side effects. Animal research shows peppermint inhibits how your body breaks down this drug.
Read the full breakdown — every affected drug type, severity by severity
Peppermint oil also affects three major enzyme systems your liver uses to clear medications. It may increase levels of CYP3A4 substrates (like felodipine and many others), CYP2C9 substrates, and CYP2C19 substrates — all rated Moderate severity.
Clinical research confirms the CYP3A4 effect: a single 600 mg dose of peppermint oil raised blood levels of felodipine in healthy volunteers. For CYP2C9 and CYP2C19, the evidence comes from lab studies so far, not yet reported in humans.
It also theoretically affects CYP1A2 substrates (Minor severity), though peppermint tea did not noticeably change caffeine metabolism in a clinical trial. Altogether, these interactions span 786 individual medications.

For each ingredient in Pepogest with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
Peppermint Aerial Parts 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.
