HelloPharmacist Scorecard of Papaya 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
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: papaya leaf extract in dry form. It's mixed with alcohol, water, and glycerin as inactive ingredients to create the liquid preparation.

Does it work?

Couldn't assess
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

This is a single-ingredient Papaya product and its label doesn't state a use — see Papaya's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence for papaya isn't well established in the data we hold. We have ratings of insufficient reliable evidence for its use in aging skin, hair loss (androgenic alopecia), colorectal cancer, and diabetes.

That means studies so far haven't been strong enough to say whether it works for these purposes.

The evidence, ingredient by ingredient Papaya

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Ripe papaya fruit eaten as food is generally well tolerated. Papaya leaf extract seems well tolerated overall, though nausea and vomiting have been reported in clinical research.

Rare serious allergic reactions are possible. The safety facts note caution: concentrated supplements and unripe papaya are less well studied than the ripe fruit you'd eat.

Unripe papaya, papaya latex, and seeds should be avoided entirely. Because little reliable safety data exists for supplement amounts, eating moderate ripe fruit is likely fine, but supplements are best avoided unless you talk it over with your doctor or pharmacist.

Side effects, ingredient by ingredient Papaya

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Papaya.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 92 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Check this product against blood thinners like warfarin, diabetes medications, amiodarone (a heart rhythm drug), and levothyroxine (thyroid medication) before you start — all are rated Moderate for interaction risk with papaya.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

If you take diabetes medication, blood thinners, heart rhythm drugs, or thyroid medication, you'll want to check this product against your exact drugs before starting — the interactions are documented and rated Moderate. Even if you don't take those medications, the safety data on concentrated papaya supplements is limited compared to eating ripe fruit.

It's a conversation worth having with your doctor or pharmacist before you add it.

Each ingredient & the kinds of drugs it affects

For each ingredient in Papaya 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.

Papaya Leaf Extract, Dry4 drug types · 92 drugs

Amiodarone (Cordarone)

Theoretically, papaya extract may increase the levels and clinical effects of amiodarone.
Animal research in rats shows that a single oral dose of papaya extract, as well as multiple doses of papaya extract daily over 14 days, prior to a single dose of amiodarone delays the time to maximum amiodarone concentration. However, only the 14-day papaya extract regimen increases systemic amiodarone exposure by 60% to 70%. This interaction has not been reported in humans.

Likelihood Probable Evidence D
Antidiabetes Drugs

Concomitant use of antidiabetic drugs with fermented papaya can produce additive effects. It is unclear if other forms of papaya have the same effect.
A small low-quality clinical study in patients with type 2 diabetes who are taking glibenclamide shows that taking a fermented papaya preparation 3 grams daily for 2 months decreases fasting and postprandial blood glucose levels when compared to baseline. Additionally, of the 25 patients in the study, 9 required a reduction in glibenclamide dose.

Likelihood Probable Evidence B
Levothyroxine (Synthroid, Others)

Theoretically, consuming large quantities of papaya fruit can reduce the clinical effects of levothyroxine.
In one case-report, a 37-year-old male with a history of thyroidectomy who was stabilized on levothyroxine for 5 years presented with hypothyroidism after consuming 5-6 papaya fruits daily for 14 days during vacation. In a controlled re-challenge test involving 5-6 papayas daily, the patient remained euthyroid for 7 days, but developed mild hypothyroidism after 14 days. Both times, thyroid levels normalized 40-45 days after discontinuing papaya.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, concomitant use of warfarin with papain-containing papaya extract might increase the effects and side effects of warfarin.
In one case report, a patient previously stable on warfarin was found to have an international normalization ratio (INR) of 7.4, which was attributed to ingestion of a supplement containing papain from papaya extract.

Papaya by Hawaii Pharm: Common Questions

Does Papaya by Hawaii Pharm interact with any medications?
Yes. Based on its ingredients, Papaya has a known interaction with 92 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Papaya contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Can I take papaya if I'm on warfarin or other blood thinners?
Not without checking first with your doctor or pharmacist. A case report shows a patient's blood-thinning effect increased dangerously after taking a papain-containing papaya supplement. Your healthcare provider can assess your individual situation and monitor you if needed.
Is this safe during pregnancy?
The data we hold shows pregnancy ratings of both Likely Safe and Possibly Unsafe for papaya — which means the evidence is mixed. You'd need to talk with your doctor about whether this product is right for you during pregnancy, rather than relying on this data alone.
What are the most common side effects?
Nausea and vomiting have been reported with papaya leaf extract in clinical research. The product is generally well tolerated, though rare severe allergic reactions are possible.
Does papaya actually work for diabetes?
We have insufficient reliable evidence to say. One small study suggested fermented papaya might add to diabetes medication effects, but the evidence isn't strong enough yet to rate it as effective.
Is the liquid form safer than other forms?
The safety data we hold doesn't compare this liquid extract to other forms. What we do know is that concentrated supplements are less well studied than eating ripe papaya as food, and unripe papaya should be avoided entirely.
Should I avoid this if I'm on levothyroxine for thyroid?
Yes, check with your doctor or pharmacist first. A case report linked consuming large amounts of papaya fruit to reduced levothyroxine effectiveness, and the interaction is rated Moderate. Your provider can advise whether this product is safe for you.
