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: organic fresh and dry valerian root. Valerian is a plant extract traditionally used to support sleep and relaxation.
The liquid also contains two inactive ingredients — vegetable glycerin and deionized water — which serve as the base for the extract.
Does it work?
Moderate evidence
Valerian is possibly effective for insomnia, meaning some evidence supports its use to help with sleep, though the research isn't conclusive. For restless legs syndrome, pre-procedural anxiety, stress, and period pain (dysmenorrhea), the evidence we hold is insufficient to say whether it works.
If you're considering it for sleep, it's worth a try, but talk with your pharmacist about realistic expectations and whether it's a good fit for your situation.
How safe is it?
Well-documented data
Valerian is generally well tolerated short-term, though long-term safety hasn't been studied carefully. Common side effects include dizziness, drowsiness, mental slowness, headache, upset stomach, and vivid dreams.
Some people report restlessness or excitability instead. If you take valerian regularly and then stop abruptly, you may experience withdrawal symptoms — anxiety, irritability, insomnia, fast heartbeat, or even agitation and hallucinations — so taper your dose slowly after extended use.
Valerian is best avoided during pregnancy; safety hasn't been established. It's also not recommended while breastfeeding due to insufficient safety data.
A few rare case reports have linked multi-ingredient products containing valerian to liver damage, though it's hard to pin that on valerian alone. If you have liver concerns, check with your pharmacist or doctor first.
Meds to double-check
Moderate interaction found
Before you take BIOVEA Valerian, double-check any CNS depressants — sedatives, sleep aids, anxiety medications, pain relievers, or anesthetics — plus alcohol. Also flag drugs broken down by glucuronidation (ask your pharmacist if you're unsure), and if you take alprazolam (Xanax), mention this supplement.
Run your exact medications through the tool on this page.
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 sleep if you're looking for a plant-based option, but it's a sedative — so don't combine it with other sedating drugs or alcohol without talking to your pharmacist first. Pregnant or breastfeeding?
Skip it. If you take any prescription medication, check it against our interaction tool before starting.

Valerian by BIOVEA Drug Interactions
HelloPharmacist Interaction Report
BIOVEA Valerian is a single-ingredient liquid supplement that does interact with medications — the main concern is additive sedation.
Valerian can amplify the drowsy, sleep-inducing effects of CNS depressants (sedatives, sleep aids, anesthetics) and alcohol, which carries Moderate severity. This means combining it with those drugs or alcohol can cause deeper drowsiness, mental slowness, and impaired coordination than either substance alone.
Read the full breakdown — every affected drug type, severity by severity
Valerian may also weakly interfere with how your body breaks down drugs metabolized by glucuronidation — an enzyme pathway — potentially raising levels of those medications. That's also Moderate severity.
Additionally, alprazolam (Xanax) is flagged separately: valerian can add to its sedative effect, and in high doses might slightly increase alprazolam levels, though the amount is unlikely to matter clinically.
Valerian shows only Minor interactions with drugs metabolized by two major liver enzymes (CYP2D6 and CYP3A4); clinical studies suggest it won't meaningfully affect them.
AltogetherI these interactions span 891 individual medications. Before you start this product, run your exact prescriptions through the medication checker below.

organic fresh and dry Valerian
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.
