HelloPharmacist Scorecard of Valerian 1,000 mg by Nature's Answer
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 root and rhizome extract at 1,000 mg per serving. Valerian is a plant extract traditionally used to support sleep and calm.
The liquid form also includes purified water, vegetable glycerin, and 12–15% certified organic alcohol as inactive ingredients that make up the base.
Does it work?
Moderate evidence
Valerian is rated possibly effective for insomnia in the data we hold—meaning some evidence supports its use, though it's not definitive. For restless legs syndrome, pre-procedural anxiety, stress, and painful periods (dysmenorrhea), the evidence isn't reliable enough for us to rate it either way.
If you're considering valerian for any of those other uses, talk with your doctor or pharmacist about what the research shows and whether it's a fit for your situation.
How safe is it?
Well-documented data
Valerian is generally well tolerated in short-term use, but long-term safety isn't 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. When you stop taking valerian after extended use, withdrawal-like symptoms—such as racing heart, anxiety, irritability, and insomnia—can occur; taper your dose slowly rather than stopping all at once.
Rare but serious reports of liver injury have been linked to multi-ingredient products containing valerian; single-ingredient products like this carry less risk, but it's worth knowing. Valerian is not recommended during pregnancy—safety data advises against it.
While breastfeeding, there isn't enough safety information, so it's best to avoid it. If you're pregnant, planning pregnancy, or nursing, talk with your doctor or pharmacist before taking this product.
Meds to double-check
Moderate interaction found
Before taking this product, check with your doctor or pharmacist if you're on CNS depressants (sleep aids, anti-anxiety drugs, sedating pain relievers, antihistamines), alprazolam (Xanax), glucuronidated drugs (ask your pharmacist which category your medications fall into), or if you drink alcohol regularly. Valerian can add to sedation and may raise levels of certain drugs, so your provider may need to adjust doses or monitor you more closely.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.
Valerian may help if you're dealing with occasional sleep trouble, but it's not your move if you're on sedating medications, alprazolam, or drinking alcohol—the combined drowsiness and mental slowness can be significant. If you take any prescription medication, especially anything that makes you sleepy, check it against the interactions below or ask your pharmacist before you start.
And if you're pregnant or breastfeeding, skip it until you've talked with your doctor.

Valerian 1,000 mg by Nature's Answer Drug Interactions
HelloPharmacist Interaction Report
Nature's Answer Valerian 1,000 mg does interact with several medication types.
Through its valerian root extract, this product has Moderate interactions with CNS depressants (sedatives, sleeping pills, anesthetics), glucuronidated drugs (certain pain relievers and other medications your liver breaks down one specific way), alprazolam (Xanax), and alcohol—all capable of adding to sedation or changing drug levels. Minor interactions are documented with drugs metabolized by CYP2D6 and CYP3A4 enzymes; clinical evidence suggests valerian is unlikely to meaningfully affect these.
Read the full breakdown — every affected drug type, severity by severity
The most serious concern is additive sleepiness and mental slowness when combined with CNS depressants. If you take any sedating medication—prescription sleep aids, anti-anxiety drugs, certain pain relievers, or antihistamines—valerian can intensify drowsiness, dizziness, and impaired thinking.
Mixing it with alcohol carries the same risk. Alprazolam (Xanax) deserves particular attention: you get additive sedation, and high-dose valerian might modestly raise alprazolam levels.
For glucuronidated drugs, valerian may slightly slow how your body clears them, raising their concentration. This category includes some pain relievers and other medications, but clinical impact is often minor.
Check your exact medications with the search tool on this page before starting, and talk with your doctor or pharmacist about any you're on—especially sedating drugs or alprazolam.

For each ingredient in Valerian 1,000 mg 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 (Valeriana officinalis) root/rhizome extract
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.
