Interactions with Drugs
Animal studies suggest that lavender used as aromatherapy or by mouth may increase the amount of drowsiness caused by some drugs. Examples include benzodiazepines such as lorazepam (Ativan®) or diazepam (Valium®), barbiturates such as phenobarbital, narcotics such as codeine, some antidepressants, and alcohol. Drowsiness caused by some seizure medicines may also be increased. Caution is advised while driving or operating machinery.
In theory, lavender may add to the effects of cholesterol-lowering drugs.
Lavender may have additive effects when used with prescription antidepressant medications, such as the tricyclic antidepressant imipramine.
Lavender may increase the risk of bleeding when taken with drugs that increase the risk of bleeding. Some examples include aspirin, anticoagulants ("blood thinners") such as warfarin (Coumadin®) or heparin, anti-platelet drugs such as clopidogrel (Plavix®), and non-steroidal anti-inflammatory drugs such as ibuprofen (Motrin®, Advil®) or naproxen (Naprosyn®, Aleve®).
Interactions with Herbs and Dietary Supplements
Lavender used as aromatherapy or by mouth may increase the amount of drowsiness caused by some herbs or supplements, such as valerian. Caution is advised while driving or operating machinery.
Lavender may interact with herbs and supplements taken for depression; use cautiously.
Lavender may increase the risk of bleeding when taken with herbs and supplements that are believed to increase the risk of bleeding. Multiple cases of bleeding have been reported with the use of Ginkgo biloba, and fewer cases with garlic and saw palmetto. Numerous other agents may theoretically increase the risk of bleeding, although this has not been proven in most cases.
