Interactions with Drugs
Peppermint oil by mouth may increase blood levels of the drugs felodipine (Plendil®) and simvastatin (Zocor®). Peppermint oil increases levels of cyclosporine in the blood. Peppermint oil used on the skin with 5-fluorouracil (5-FU) may increase the rate of absorption of 5-FU.
Peppermint oil may interfere with the way the body processes certain drugs using the liver's "cytochrome P450" enzyme system. As a result, the levels of these drugs may be increased in the blood and may cause increased effects or potentially serious adverse reactions. Patients using these medications should check the package insert and speak with a qualified healthcare provider including a pharmacist about possible interactions.
Peppermint may also interact with antacids, other calcium channel blockers, or drugs that lower high blood pressure. Caution is advised.
Interactions with Herbs and Supplements
Peppermint oil may interfere with the way the body processes certain herbs or supplements using the liver's "cytochrome P450" enzyme system. As a result, the levels of other herbs or supplements may be too high in the blood. It may also alter the effects that other herbs or supplements possibly have on the P450 system. Patients using these medications should check the package insert and speak with a qualified healthcare provider including a pharmacist about possible interactions.
Peppermint may also interact with herbs and supplements that raise or lower blood pressure or have antacid properties. Caution is advised.
