HelloPharmacist Scorecard of Hops Alcohol Free 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: hops flower extract in a dried form. Hops is a plant traditionally used for brewing beer and has been studied for a range of purposes including sleep, anxiety, and digestive comfort.
The liquid also contains glycerin and water as inactive ingredients to preserve and deliver the extract.
Does it work?
Not established
The evidence isn't established in our data for any of hops' common uses — age-related cognitive decline, sexual dysfunction, anxiety, ADHD, indigestion (dyspepsia), and insomnia all carry a rating of insufficient reliable evidence. That means there isn't enough high-quality research to say whether hops actually works for these purposes.
If you're considering it for a specific reason, talk that through with your doctor or pharmacist.
How safe is it?
Well-documented data
Hops is generally well tolerated over the short term but may make you drowsy — don't drive or operate machinery until you know how it affects you. Long-term safety hasn't been well studied, so we don't have a clear picture of what happens with extended use.
The safety data advises against use during pregnancy. There isn't enough information to know whether it's safe while breastfeeding — talk with your doctor or pharmacist for personalized advice.
In rare cases, hops supplements combined with soy have been linked to postmenopausal bleeding, though it's unclear whether hops alone is responsible.
Meds to double-check
Moderate interaction found
Check with your doctor or pharmacist before taking this product if you're on sedative or anti-anxiety drugs, hormone replacement therapy, birth control pills containing estrogen, or any heart, immune-system, or cancer medications that are metabolized by the liver. The sedative interaction is the most serious documented concern.
The bottom line
Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.
Hops Alcohol Free might appeal to someone interested in traditional herbal support, but the evidence for what it actually does isn't well established. The bigger concern is that it can add to the effects of sedatives and may interfere with hormone medications and certain other drugs.
Before you take it, check your exact medications with your doctor or pharmacist — especially if you're on sleep aids, anxiety medications, or hormone therapy.

Hops Alcohol Free by Hawaii Pharm Drug Interactions
HelloPharmacist Interaction Report
Hops Alcohol Free from Hawaii Pharm contains hops flower extract, which has documented interactions with sedative drugs, estrogen-containing medications, and certain other drug types.
The most serious concern is with CNS depressants (sedatives, sleeping pills, anti-anxiety medications) — hops may add to their sedating effects, potentially increasing drowsiness and impairment.
Read the full breakdown — every affected drug type, severity by severity
Hops may also interfere with estrogen-based medications, including hormone replacement therapy and birth control pills. The concern is theoretical — based on how hops compounds bind to estrogen receptors — but most hops extracts contain only small amounts of these active constituents.
Additionally, hops interacts with a large number of medications that are broken down by liver enzymes called CYP3A4 and CYP1A2 (including some heart drugs, immunosuppressants, and cancer medications), though the actual clinical impact appears to be minor or possibly none at typical doses.
Altogether, these interactions span 864 individual medications. Before you start hops, run your exact medications through the search tool on this page — especially if you take sedatives, hormone replacements, or any heart, immune, or cancer drugs.

For each ingredient in Hops Alcohol Free 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.
Hops Flower Extract, Dry
Cns Depressants
Theoretically, concomitant use of hops with sedative drugs might cause additive sedation.
Some animal research shows that hops has sedative effects.
Estrogens
Theoretically, concomitant use of large amounts of hops might interfere with hormone replacement therapy due to competition for estrogen receptors.
In vitro research suggests that certain hops constituents can competitively bind to estrogen receptors. However, most hops extracts contain very small amounts of these constituents.
Cytochrome P450 1A2 (Cyp1A2) Substrates
Hops extract does not seem to affect the metabolism of CYP1A2 substrates.
In vitro research suggests that flavonoid constituents of hops inhibit CYP1A2 enzyme activity. However, a pharmacokinetic study in healthy postmenopausal patients shows that taking a standardized extract of spent hops containing prenylated phenols, as 59.5 mg twice daily for 2 weeks, does not affect levels of caffeine, a CYP1A2 probe substrate.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, hops extract might alter metabolism of CYP3A4 substrates; however, this effect may not be clinically significant.
Animal research suggests that specific constituents of hops, called lupulones, can induce hepatic CYP3A4 enzyme activity. However, a pharmacokinetic study in healthy postmenopausal patients with normal metabolism shows that taking a standardized extract of spent hops containing prenylated phenols, as 59.5 mg twice daily for 2 weeks, decreases the concentration of alprazolam, a CYP3A4 probe substrate, by 7.6%. This reduction is unlikely to be clinically relevant.
