HelloPharmacist Scorecard of Relax And Sleep by Spring Valley
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 two active ingredients: organic passion flower extract and organic valerian powder. Passion flower is used traditionally for sleep and anxiety, while valerian powder has been used for insomnia and restlessness.
The product also contains inactive ingredients—hypromellose and organic rice hull concentrate—which are binders and capsule materials that help hold the supplement together.
Does it work?
Moderate evidence
Passion flower is rated Possibly Effective for insomnia and for calming anxiety before medical procedures. Valerian is also rated Possibly Effective for insomnia.
For other uses listed on the label—ADHD, benzodiazepine withdrawal, restless legs, general stress, and menstrual cramps—the evidence we hold isn't strong enough to establish whether either ingredient works. Talk with your doctor if you're considering this product for a specific condition.
How safe is it?
Well-documented data
Both ingredients are generally well tolerated in the short term, though drowsiness is common—which is expected when you're trying to sleep, but be cautious if you drive or operate machinery. The most common side effects from passion flower are confusion, dizziness, and sedation.
Valerian can cause dizziness, drowsiness, mental slowness, headache, and vivid dreams; if you stop valerian suddenly after long-term use, withdrawal symptoms like anxiety, irritability, and trouble sleeping can happen, so taper slowly. Passion flower is rated Possibly Unsafe in pregnancy due to lack of safety data and possible effects on the uterus, and there isn't enough information to use it while breastfeeding.
Valerian's safety hasn't been established in pregnancy or lactation either. If you're pregnant, nursing, or planning to become pregnant, talk with your doctor or pharmacist before taking this product.
Meds to double-check
Moderate interaction found
Before taking this product, double-check any sedative or sleep medications you're on, including benzodiazepines, prescription sleep aids, and over-the-counter sleep products—both ingredients can add to their drowsy effects (Moderate severity). Also flag any alcohol use (Moderate).
If you take alprazolam (Xanax) in particular, talk with your pharmacist. Additionally, check whether any of your medications are metabolized through glucuronidation or the CYP3A4 enzyme; the search tool on this page can help you confirm.
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.
This product may help with insomnia and pre-procedure anxiety if you're looking for a herbal option. However, it interacts with sedative medications and alcohol, so it's not right for everyone.
If you take any prescription or over-the-counter drugs—especially sedatives, sleep aids, or anti-anxiety medications—check with your pharmacist or doctor before you start. The same goes if you're pregnant, breastfeeding, or planning to be.

Relax And Sleep by Spring Valley Drug Interactions
HelloPharmacist Interaction Report
Spring Valley's Relax and Sleep contains passion flower and valerian, both of which interact with medications.
The most serious concern is with sedative drugs (CNS depressants): both ingredients can add to their effects, causing extra drowsiness and side effects. This is a Moderate-severity interaction.
Read the full breakdown — every affected drug type, severity by severity
Valerian also interacts with alcohol (Moderate severity) — combining them can cause excessive sedation. It may also affect drugs metabolized through glucuronidation (Moderate), a liver process that clears certain medications from your body.
Alprazolam (Xanax) deserves special mention: valerian's sedative effects can compound with it, and high-dose valerian might slightly raise alprazolam levels.
Both ingredients have Minor interactions with drugs broken down by a liver enzyme called CYP3A4. Passion flower also has a Minor interaction with OATP transporters, which move certain drugs into cells.
Altogether, these interactions span 932 individual medications.
Before you start this product, check your exact medications with the search tool on this page — especially if you take sedatives, sleep aids, anti-anxiety drugs, or anything metabolized by your liver.

organic Valerian powder
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.
organic Passion Flower extract
Cns Depressants
Concomitant use of passion flower with sedative drugs might cause additive effects and side effects.
Research in animals and humans shows that passion flower has sedative effects which can be additive when used with sedative medications like lorazepam.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, passion flower might decrease the effects of CYP3A4 substrates.
In vitro research suggests that passion flower can induce CYP3A4 enzymes, albeit to a much lower degree than rifampin, a known CYP3A4 inducer.
Organic Anion-Transporting Polypeptide Substrates (Oatp)
Theoretically, passion flower might reduce the bioavailability of OATP2B1 and OATP1A2 substrates.
In vitro research shows that the passion flower constituents apigenin and vitexin inhibit OATP2B1 and OATP1A2. This inhibition may be dose-dependent. One specific high-flavonoid passion flower extract (Valverde) seems to inhibit OATP2B1 and OATP1A2, while another extract with a lower flavonoid concentration (Arkocaps) shows less potent inhibition. OATPs are responsible for the uptake of drugs and other compounds into the body; however, the specific activities of OATP2B1 and OATP1A2 are not well characterized.
