What medications can interact with tarragon?

Following are some interactions that can occur when tarragon is taken with certain medications:

• Tarragon 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, antiplatelet drugs such as clopidogrel (Plavix®), and nonsteroidal anti-inflammatory drugs such as ibuprofen (Motrin®, Advil®) or naproxen (Naprosyn®, Aleve®).

• Tarragon may lower blood sugar levels. Caution is advised when using medications that may also lower blood sugar. Patients taking insulin or drugs for diabetes by mouth should be monitored closely by a qualified healthcare professional, including a pharmacist. Medication adjustments may be necessary.

• Tarragon 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. Caution is advised while driving or operating machinery.

• Tarragon 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 change in the blood and may cause increased or decreased effects or potentially serious adverse reactions. Patients taking any medications should check the package insert and speak with a qualified healthcare professional, including a pharmacist, about possible interactions.

• Tarragon may also interact with antiallergy agents, antibiotics, anticancer agents, antifungal agents, anti-inflammatory agents, antiseizure agents, drugs that may affect the immune system, drugs that may affect the nervous system, drugs that may damage the liver, and drugs that prevent nausea and vomiting.
