HelloPharmacist Scorecard of Valerian by Hawaii Pharm
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: certified organic valerian extract. Valerian is an herbal supplement derived from the root of the valerian plant, traditionally used to support sleep and relaxation.
The liquid form also includes vegetable palm glycerin and pharmaceutical-grade alcohol as inactive ingredients.
Does it work?
Moderate evidence
The evidence for valerian's effectiveness is mixed. It is rated possibly effective for insomnia, meaning some research supports its use for sleep, though the evidence is not conclusive.
For restless legs syndrome, pre-procedural anxiety, stress, and dysmenorrhea (period pain), the evidence we hold is insufficient to rate its effectiveness.
How safe is it?
Well-documented data
Valerian is generally well tolerated in the short term, but long-term safety hasn't been thoroughly studied. The most common side effects are dizziness, drowsiness, and mental slowness; headache, stomach upset, excitability, and vivid dreams have also been reported.
If you use valerian for an extended period and then stop suddenly, you may experience withdrawal symptoms like increased heart rate, anxiety, irritability, and insomnia—the safety data advises tapering your dose slowly rather than stopping abruptly. The safety data advises against valerian during pregnancy and breastfeeding because there isn't enough information to know it's safe in those situations.
Rare cases of liver injury have been reported, though most involved multi-ingredient products; talk with your doctor or pharmacist if you have liver disease or concerns.
Meds to double-check
Moderate interaction found
Before taking Hawaii Pharm Valerian, check with your doctor or pharmacist if you take central nervous system depressants (sedatives, sleep aids, anesthetics, or opioids), alprazolam or other benzodiazepines, drugs metabolized by glucuronidation in the liver, or drink alcohol regularly. Moderate interactions are documented with all of these.
Also check if you take medications broken down by the liver enzymes CYP2D6 or CYP3A4, though valerian's effect on these enzymes is minor in practice.
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 with sleep if you have insomnia, though the evidence is not definitive. If you take any sedating medications, anti-anxiety drugs, or substances metabolized by your liver, or if you drink alcohol regularly, check your exact medications with your doctor or pharmacist before starting.
Avoid it during pregnancy and breastfeeding, and don't stop suddenly after long-term use—taper gradually to prevent withdrawal symptoms.

Valerian by Hawaii Pharm Drug Interactions
HelloPharmacist Interaction Report
Hawaii Pharm Valerian is a single-ingredient liquid extract that interacts with several medication types.
The most serious interactions are Moderate in severity and involve central nervous system depressants (CNS depressants)—medications that slow brain activity, like sedatives, sleep aids, and anesthetics. Valerian can add to their sedative effects, potentially causing excessive drowsiness or impaired thinking.
Read the full breakdown — every affected drug type, severity by severity
Valerian also has Moderate interactions with glucuronidated drugs (medications your liver processes through a specific pathway) and with alprazolam (Xanax, an anti-anxiety medication). It may modestly increase levels of alprazolam in your body, though this is unlikely to be clinically significant on its own.
Alcohol is another Moderate concern—combining it with valerian can deepen sedation. Additionally, Minor interactions are documented with drugs metabolized by the liver enzymes CYP2D6 and CYP3A4, though valerian's effect on these enzymes appears limited in real-world use.
Altogether, these interactions span 903 individual medications. Use the medication checker below to look up your exact prescriptions before starting this product.

certified organic Valerian 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.
