Is Eleuthero Safe With Psychiatric Medications?
In our latest question and answer, the pharmacist discusses the potential interaction between eleuthero and psychiatric drugs.
Do you know if Eleuthero root is compatible with basic psychiatric medicines and other antidepressants since you're an online pharmacist who discusses the benefits of herbs?
Jul 20, 2023- Eleuthero may theoretically increase blood levels of some psychiatric medications by affecting how your liver breaks them down, based mainly on lab and animal studies rather than proven human effects. Most research suggests that even if eleuthero does affect these liver enzymes, the change is unlikely to be clinically significant in most people. Always talk to your doctor or pharmacist about your specific psychiatric medications before taking eleuthero to get personalized guidance about your individual situation.
Quick Answer
Hello and thanks for reaching out to us!
This is a very broad question as a lot of medications would fit into the classification of 'psychiatric drugs,' but yes, it is important to consider potential interactions with Eleuthero (also known as Siberian ginseng).
Theoretical evidence suggests that Eleuthero may increase the levels of drugs metabolized by certain liver enzymes, specifically CYP1A2, CYP2C9, CYP2D6, and CYP3A4. This covers a lot of different drugs.
However, it is important to note that most studies that report potential interactions are lab or animal studies. Generally, the effects seen in these studies have not been reported in humans.
As always, it is important to consult with your doctor to evaluate specific medications and their potential interactions with eleuthero. Additionally, you want to be sure you're appropriately monitored if you start taking anything new.
Detailed Answer
As mentioned in the section above, if you are considering taking eleuthero, you have to consider potential drug interactions.
Eleuthero root may affect certain enzymes in the liver, known as cytochrome P450 enzymes, which play a crucial role in the metabolism of various medications.
Lab studies have reported that Eleuthero may inhibit the following enzymes (in brackets I have given some examples of psychiatric drugs that are metabolized by that enzyme):
- Cytochrome P450 1A2 (CYP1A2): [clozapine, fluvoxamine, olanzapine, risperidone, and theophylline]
- Cytochrome P450 2C9 (CYP2C9): [amitriptyline, diazepam, fluoxetine, sertraline, and warfarin]
- Cytochrome P450 2D6 (CYP2D6): [aripiprazole, haloperidol, paroxetine, venlafaxine, and codeine]
- Cytochrome P450 3A4 (CYP3A4): [alprazolam, clonazepam, quetiapine, valproate, and midazolam]
When Eleuthero root inhibits these cytochrome P450 enzymes, the metabolism of certain medications can be impaired.
This impairment can lead to a decreased clearance of the drugs, resulting in higher levels of the medications circulating in the body. Elevated drug levels can potentially increase the risk of side effects or toxicity associated with these medications.
For example, if Eleuthero inhibits CYP1A2, which is responsible for metabolizing medications such as clozapine, fluvoxamine, olanzapine, risperidone, and theophylline, it can lead to an increase in the blood levels of these drugs. An elevated concentration of any of these medications potentially causes an increase in the risk and severity of their side effects.
Additional Thoughts
I want to emphasize that the interactions between eleuthero and the psychiatric medications I mentioned in this answer are based on theoretical evidence derived from laboratory and animal studies. They have not been extensively tested in humans.
While there is a potential for Eleuthero to inhibit certain enzymes involved in drug metabolism, actual clinical evidence of these interactions is limited. Therefore, it is essential to consider this information as a "good to know" cautionary guideline rather than absolute certainty. I do not mean to imply that these interactions will certainly occur in every individual.
In fact, most studies on the matter report that even if there is some indication that eleuthero may alter CYP enzyme activity, it generally wouldn't be to a clinically significant degree.
Always consult with a healthcare professional or pharmacist to evaluate your specific medications, and health conditions so you can get some personalized guidance.
