HelloPharmacist Scorecard of Prune Fig Tab by Douglas Laboratories

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 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains 2 active ingredients: prune concentrate and black fig concentrate. Prune concentrate is used for its possible effectiveness with constipation; the other claimed uses (bone health, cholesterol, and liver support) don't yet have reliable evidence behind them in the data we hold.

Black fig concentrate has insufficient evidence for any of the conditions listed—constipation, eczema, diabetes, melasma, and vitiligo—so we can't say whether it works for those purposes. The tablet also contains inactive ingredients (calcium, cellulose, vegetable stearate, and silica) that act as binders and fillers.

Does it work?

Moderate evidence
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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: constipation and digestive health support.
  • We looked for evidence on: Constipation, Postoperative ileus, Bowel regularity, Digestive comfort.
  • The strongest evidence on file: Plum is rated "Possibly Effective" for Constipation (Natural Medicines).
  • Also on file: Fig is rated "Insufficient Reliable Evidence To Rate" for Constipation.
  • Also on file: Plum is rated "Insufficient Reliable Evidence To Rate" for Postoperative ileus.

Prune concentrate is possibly effective for constipation based on available evidence. For osteopenia (low bone density), dyslipidemia (cholesterol issues), and hepatitis, the evidence isn't established—we don't have reliable data to say whether prune helps.

Black fig concentrate has insufficient evidence for any of its listed uses: constipation, eczema, diabetes, melasma, and vitiligo. If you're taking this product for any of those conditions, talk with your pharmacist about whether the evidence supports its use for your specific situation.

The evidence, ingredient by ingredient Plum Fig

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Prunes and prune concentrate are generally well tolerated when taken by mouth. The most common side effects are gastrointestinal—gas and diarrhea.

Serious adverse effects are rare but include allergic reactions; dried plums can occasionally cause bowel obstruction or perforation if not chewed properly. Black fig fruit is also well tolerated as food, though concentrated leaf products are less studied.

Orally, fig fruit can rarely cause allergic reactions or anaphylaxis. When fig leaf is applied to skin or the skin is exposed to the plant, it may cause photodermatitis (sun-triggered burns), and you should avoid excessive sunlight while using products with fig leaf.

Concentrated fig supplements lack solid safety data in pregnancy and lactation, whereas fig fruit as a food is considered likely safe during those times. Prune supplement safety in pregnancy and lactation hasn't been thoroughly studied.

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?
  • 2 of the 2 matched ingredients can interact with medications — Fig, Plum.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 509 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 with your pharmacist if you take blood sugar medications or insulin (antidiabetes drugs)—fig concentrate may boost their effects and lower your blood sugar more than intended. If you're on blood thinners or antiplatelet drugs (like warfarin or aspirin), prune concentrate may increase bleeding risk.

If you take photosensitizing drugs like amitriptyline or antibiotics such as ciprofloxacin or tetracyclines, fig concentrate could raise your risk of sun-triggered skin burns.

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 constipation, though evidence for other uses is thin or absent. If you take blood thinners, blood sugar medications, or drugs that increase sun sensitivity, check with your pharmacist first—the interactions are documented and potentially serious.

Prune Fig Tab by Douglas Laboratories: Common Questions

Does Prune Fig Tab by Douglas Laboratories interact with any medications?
Yes. Based on its ingredients, Prune Fig Tab has a known interaction with 509 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Prune Fig Tab contains 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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.
Will this help my constipation?
Prune concentrate is possibly effective for constipation based on available evidence. Black fig concentrate doesn't have reliable evidence behind it for constipation. Your pharmacist can tell you whether either ingredient is a good fit for your situation.
Can I take this if I'm pregnant or breastfeeding?
Black fig fruit is considered likely safe during pregnancy and lactation. However, concentrated fig leaf products haven't been well studied in pregnancy, and we don't have enough safety data on prune supplements either. Talk with your pharmacist or doctor about what's right for you during pregnancy or while nursing.
What are the most common side effects?
The main side effects are gastrointestinal—gas and diarrhea. Both ingredients are generally well tolerated when taken by mouth in normal amounts. Serious side effects are rare.
Why can't I take this with the sun if I'm on certain antibiotics?
Fig leaf contains compounds called psoralens that can cause photodermatitis—a painful, sun-triggered skin reaction—especially when combined with photosensitizing drugs like some antibiotics and other medications. Multiple cases have been reported, and a few were serious enough to need hospitalization. Avoid excessive sunlight while taking products with fig leaf if you're on those drugs.
Is this safe if I take insulin for diabetes?
No—the black fig concentrate in this product may enhance how well insulin lowers your blood sugar, which could cause your blood sugar to drop too low. Talk with your pharmacist or doctor before taking this if you're on insulin or other diabetes medications.
Does this product have any fillers?
Yes. Beyond the two active ingredients, the tablet contains calcium, cellulose, vegetable stearate, and silica as inactive ingredients that help hold the tablet together.
