Interaction Details

Pharmacist Analysis
While there is no known interaction between valerian and the drug in question here, it does have potential interactions with other drugs that are important to be aware of.
For example, valerian may enhance the effects of central nervous system depressants, such as alcohol, benzodiazepines, and barbiturates. This means that combining valerian with these drugs can lead to excessive sedation and other side effects, such as dizziness and impaired coordination.
Similarly, if you take a drug that causes you to feel tired (e.g., Benadryl), valerian may enhance that effect.
Valerian may also interact with certain medications metabolized by the liver, such as statins and some antidepressants, as it can affect the liver enzymes that break down these drugs. For example, valerian may affect drugs metabolized via the CYP3A4 enzyme.
This can result in increased levels of these medications in the bloodstream, leading to potential side effects and toxicity.
We have hundreds of interactions listed for valerian that you can find in this interaction tool, but as always, if you are taking any prescription medications, it is important to talk to your healthcare provider before using valerian or any other supplements to ensure they are safe and appropriate for you.
- Dr. Brian Staiger, PharmDValerian Overview
Valerian (Valeriana officinalis) is a perennial herb native to Europe and Asia. The plant is known for its strong, distinctive odor and its purported medicinal effects.
Valerian contains a number of active compounds, including valerenic acid and valepotriates, which are believed to have a sedative effect on the body and are may to be helpful in the treatment of insomnia and anxiety. Valerian is also believed to have mild tranquilizing and muscle-relaxing properties and may be helpful in the treatment of muscle spasms and other muscle disorders.
The root of the valerian plant is most commonly utilized in dietary supplements and is often standardized for valerenic acid content.
Eltrombopag Overview
-
Eltrombopag is used to increase the number of platelets (cells that help the blood clot) to decrease the risk of bleeding in adults and children 1 year of age and older who have chronic immune thrombocytopenia (ITP; an ongoing condition that may cause unusual bruising or bleeding due to an abnormally low number of platelets in the blood) and who have not been helped or cannot be treated with other treatments, including medications or surgery to remove the spleen. Eltrombopag is also used to increase the number of platelets in people who have hepatitis C (a viral infection that may damage the liver) so that they can begin and continue treatment with interferon (Peginterferon, Pegintron, others) and ribavirin (Rebetol). Eltrombopag is also used in combination with other medications to treat aplastic anemia (condition in which the body does not make enough new blood cells) in adults and children 2 years of age and older. It is also used to treat aplastic anemia in adults who have not been helped with other medications. Eltrombopag is used to increase the number of platelets enough to decrease the risk of bleeding in people with ITP or aplastic anemia, or to allow treatment with interferon and ribavirin in people with hepatitis C. However it is not used to increase the number of platelets to a normal level. Eltrombopag should not be used to treat people who have low numbers of platelets due to conditions other than ITP, hepatitis C, or aplastic anemia. Eltrombopag is in a class of medications called thrombopoietin receptor agonists. It works by causing the cells in the bone marrow to produce more platelets.
