HelloPharmacist Scorecard of Valerian by BIOVEA
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
This product contains one active ingredient: Valerian, a dried plant extract. Valerian root has been used for centuries as a calming herb.
The liquid form also contains grain alcohol and water as inactive ingredients to preserve and deliver the valerian.
Does it work?
Moderate evidence
Valerian is possibly effective for insomnia — some evidence supports its use for sleep troubles, though the research isn't conclusive. For restless legs syndrome, pre-procedural anxiety, stress, and dysmenorrhea (menstrual cramps), the evidence isn't established enough in our data for us to rate it either way.
How safe is it?
Well-documented data
Valerian is generally well tolerated in the short term, but long-term safety hasn't been well studied. The most common side effects are dizziness, drowsiness, mental slowness, headache, stomach upset, and vivid dreams.
Some people report restlessness or excitability instead. If you take valerian regularly and then stop abruptly, you may experience withdrawal symptoms like faster heart rate, anxiety, irritability, or trouble sleeping — taper your dose slowly after extended use.
Valerian is not recommended during pregnancy, as safety hasn't been established. It should also be avoided while breastfeeding.
There have been rare case reports of liver problems linked to multi-ingredient products containing valerian; single-ingredient valerian products have less evidence of this risk, but it's worth knowing.
Meds to double-check
Moderate interaction found
Before taking Valerian, double-check with your pharmacist if you take any central nervous system depressants like sedatives, sleep aids, or antidepressants (Moderate interaction). Also check if you're on medications that the liver breaks down via glucuronidation, or if you use alprazolam or drink alcohol regularly (Moderate).
Drugs processed by CYP2D6 or CYP3A4 enzymes show only Minor interactions, but mention them too.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
Valerian may help with insomnia, especially if you're looking for a plant-based option. But if you take any sedating medications, anti-anxiety drugs like alprazolam, or drink alcohol regularly, talk with your pharmacist first.
It's not for use in pregnancy or while nursing. Any medication questions should be checked against the tool on this page before you start.

Valerian by BIOVEA Drug Interactions
HelloPharmacist Interaction Report
Valerian from BIOVEA is a single-ingredient liquid supplement that does interact with several categories of medications.
The most serious interactions are Moderate in severity and involve central nervous system (CNS) depressants — drugs that slow brain activity, like sedatives and sleep aids. Valerian can add to their sedative effects, deepening drowsiness and mental slowness.
Read the full breakdown — every affected drug type, severity by severity
Valerian also has Moderate interactions with glucuronidated drugs (medications your body breaks down through a specific liver pathway). In lab studies, valerian can weakly block this pathway and raise drug levels, though we can't yet say how much this matters in real patients.
Alprazolam (Xanax), a common anti-anxiety medication, falls into this group; valerian may boost both its sedative effect and its blood levels. Alcohol also pairs with valerian in a Moderate interaction — the two together can produce excessive drowsiness.
Valerian shows only Minor interactions with drugs broken down by two other liver enzymes (CYP2D6 and CYP3A4 substrates); clinical studies suggest these are unlikely to be clinically significant. Altogether, these interactions span 891 individual medications.

For each ingredient in Valerian with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
Valerian, Fresh, Dry
Alcohol (Ethanol)
Valerian can have additive sedative effects when used concomitantly with alcohol.
Valerian has sedative effects. Theoretically, valerian might have an additive sedative effect when combined with alcohol. Excessive sedation has been reported in an alcohol-abusing individual who took valerian and Gingko biloba. However, the potential interaction between valerian and alcohol has been disputed in other research. Limited evidence suggests that a combination of valerian 160 mg and lemon balm 80 mg (Euvegal) does not cause further deterioration in reaction ability and reaction rate when taken with alcohol as compared to the effects of alcohol alone.
Alprazolam (Xanax)
Valerian can have additive sedative effects when used with alprazolam. Also, valerian in high doses might modestly increase alprazolam levels, though this is not likely to be clinically significant.
Valerian has sedative effects. Theoretically, valerian might cause additive sedation when combined with alprazolam. Also, a small pharmacokinetic study shows that taking valerian extract 1000 mg daily (providing 11 mg valerenic acid) might increase alprazolam levels by about 19%. This might be due to valerian's mild inhibition of cytochrome P450 3A4 (CYP3A4). Despite being statistically significant, this increase is not likely to be clinically significant.
Cns Depressants
Valerian can have additive sedative effects when used concomitantly with CNS depressant drugs.
Theoretically, concomitant use of valerian and drugs with sedative and anesthetic properties may cause additive therapeutic and adverse effects.
Glucuronidated Drugs
Valerian might weakly inhibit glucuronidation and increase concentrations of drugs metabolized by UGT1A1 and UGT2B7.
In vitro research shows that methanolic valerian extract and valerenic acid might competitively inhibit UDP-glucuronosyltransferase (UGT) 1A1 (UGT1A1) and UGT2B7.
Cytochrome P450 2D6 (Cyp2D6) Substrates
Valerian does not seem to have a clinically relevant effect on levels of drugs metabolized by CYP2D6.
Although some in vitro evidence suggests that valerian affects CYP2D6, clinical pharmacokinetic (PK) studies show that valerian is unlikely to affect the CYP2D6 enzyme. In one PK study, taking valerian 1000 mg (providing about 11 mg valerenic acid) nightly for 14 days did not affect the metabolism of dextromethorphan, a CYP2D6 substrate. In another PK study, taking valerian 125 mg three times daily for 28 days did not affect metabolism of debrisoquine, an accepted CYP2D6 probe-substrate.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Valerian does not seem to have a clinically relevant effect on levels of drugs metabolized by CYP3A4.
Although some in vitro evidence suggests that valerian extract might inhibit or induce CYP3A4, clinical pharmacokinetic (PK) studies show that valerian does not have a clinically significant effect on the CYP3A4 enzyme. In one PK study, taking valerian 125 mg three times daily for 28 days did not affect metabolism of midazolam, an accepted CYP3A4 probe-substrate. In another PK study, taking valerian 1000 mg (providing about 11 mg valerenic acid) nightly for 14 days modestly increases levels of alprazolam, a CYP3A4 substrate, suggesting mild inhibition of CYP3A4. However, this mild inhibition is unlikely to be clinically relevant.
