Interaction Details
There were no interactions found between Hydroxychloroquine and Valerian. This does not mean the potential for an interaction does not exist, however. There is often a lack of studies and data surrounding traditional medicine, especially concerning drug interactions, so it is important to always consult your provider before making any changes to your medication regimen.
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.

Hydroxychloroquine Overview
-
Hydroxychloroquine is used to prevent and treat acute attacks of malaria in adults and children weighing more than 31 kg (68 lbs). It is also used to treat discoid lupus erythematosus (DLE; a chronic inflammatory condition of the skin) or systemic lupus erythematosus (SLE or lupus; an autoimmune disease in which the immune system attacks healthy parts of the body such as joints, skin, blood vessels, and organs) and rheumatoid arthritis. Hydroxychloroquine is in a class of drugs called antimalarials and is also an antirheumatic drug. It works by killing the organisms that cause malaria. Hydroxychloroquine may work to treat rheumatoid arthritis and systemic lupus erythematosus by decreasing the activity of the immune system.
