HelloPharmacist Scorecard of Berberine by Integrative Therapeutics
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: berberine hydrochloride, a plant-derived alkaloid. The capsule also holds inactive ingredients — hypromellose, cellulose, calcium laurate, and silica — that serve as binders and fillers.
Does it work?
Moderate evidence
Research suggests berberine may help with several conditions. It's rated possibly effective for high cholesterol (hyperlipidemia), high blood pressure (hypertension), type 2 diabetes, polycystic ovary syndrome (PCOS), and H. pylori infection.
That said, 'possibly effective' means the evidence is promising but not yet definitive — more research would strengthen our confidence in these uses.
How safe is it?
Well-documented data
Berberine is generally well tolerated over the short term, but digestive side effects are common: abdominal pain, bloating, constipation, diarrhea, gas, nausea, and vomiting. Some people also report dizziness, drowsiness, fatigue, or headache.
The safety data advises against berberine during pregnancy and breastfeeding — it can cross the placenta and enter breast milk, and has been associated with harm in newborns.
Meds to double-check
Major interaction found
Before you start berberine, check your exact medications against this list: cyclosporine (Major severity); blood pressure medications, diabetes drugs, blood thinners, sedating medications, and any drug metabolized by the liver enzymes CYP3A4, CYP2D6, or CYP2C9 (all Moderate severity). Use the medication checker on this page with your prescription names and dosages.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Major medication interactions have been identified, and safety information is well characterized.
Berberine may be worth considering if you're interested in supporting cholesterol, blood sugar, or blood pressure naturally — but only after checking it against your full medication list. If you take cyclosporine, blood thinners, blood pressure drugs, diabetes medications, or sedatives, talk with your pharmacist or doctor first.
Pregnancy and breastfeeding are off-limits.

Berberine by Integrative Therapeutics Drug Interactions
HelloPharmacist Interaction Report
Berberine by Integrative Therapeutics interacts with a significant number of medications, and the most serious concern is cyclosporine (an immunosuppressant).
Berberine can inhibit the enzyme that breaks down cyclosporine, raising its blood levels and increasing the risk of toxicity — this is a Major interaction and a reason to pause before starting this product if you take it.
Read the full breakdown — every affected drug type, severity by severity
The remaining interactions are Moderate in severity. Berberine may add to the effects of blood pressure medications and can theoretically lower your blood sugar further if you're already on diabetes drugs — both carry a real risk of dropping your pressure or glucose too far.
It can also slow the metabolism of several other drug classes: blood thinners (anticoagulants and antiplatelet drugs), sedating medications (CNS depressants), and drugs metabolized by three key liver enzymes (CYP3A4, CYP2D6, and CYP2C9 substrates), raising their levels in your bloodstream.
Although berberine is the only active ingredient here, it touches a wide range of medications. Altogether, these interactions span 1,148 individual medications.

For each ingredient in Berberine 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.
Berberine Hydrochloride
Cyclosporine (Neoral, Sandimmune)
Berberine can increase serum levels of cyclosporine.
Berberine can reduce metabolism and increase serum levels of cyclosporine. Berberine might inhibit cytochrome P450 3A4 (CYP3A4), which metabolizes cyclosporine.
Anticoagulant/Antiplatelet Drugs
Theoretically, berberine might increase the risk of bleeding when used with anticoagulant or antiplatelet drugs.
In vitro and in vivo research suggest that berberine can inhibit platelet aggregation. Theoretically, berberine might have additive effects when used with anticoagulant and antiplatelet drugs and increase the risk of bleeding.
Antidiabetes Drugs
Theoretically, berberine may increase the risk of hypoglycemia when taken with antidiabetes drugs.
Clinical research shows that berberine may lower blood glucose levels. Theoretically, berberine might have additive effects with antidiabetes drugs and increase the risk of hypoglycemia.
Antihypertensive Drugs
Theoretically, berberine might have additive effects with antihypertensive drugs.
Animal research suggests that berberine can have hypotensive effects. Also, a clinical study suggests that taking berberine in combination with amlodipine can lower systolic and diastolic blood pressure when compared with amlodipine alone.
Cns Depressants
Theoretically, berberine might increase the sedative effects of CNS depressants.
Animal research suggests that berberine may have sedative effects. Theoretically, use of berberine along with CNS depressants might produce additive therapeutic and adverse effects.
Cytochrome P450 2C9 (Cyp2C9) Substrates
Theoretically, berberine might increase serum levels of drugs metabolized by CYP2C9.
Preliminary clinical research shows that berberine can inhibit CYP2C9. Theoretically, taking berberine with drugs metabolized by CYP2C9 might increase drug levels and increase the risk of adverse effects.
Cytochrome P450 2D6 (Cyp2D6) Substrates
Theoretically, berberine might increase serum levels of drugs metabolized by CYP2D6.
In vitro research and preliminary clinical evidence show that berberine can inhibit CYP2D6. Theoretically, use of berberine with drugs metabolized by CYP2D6 might increase drug levels and increase the risk of adverse effects.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, berberine might increase serum levels of drugs metabolized by CYP3A4.
In vitro research and preliminary clinical research show that berberine moderately inhibits CYP3A4. Theoretically, use of berberine with drugs metabolized by CYP3A4 might increase drug levels and increase the risk of adverse effects.
Dextromethorphan (Robitussin Dm, Others)
Theoretically, berberine may increase serum levels of dextromethorphan.
Preliminary clinical research shows that berberine can inhibit cytochrome P450 2D6 (CYP2D6) activity and reduce the metabolism of dextromethorphan. This may increase the effects and side effects of dextromethorphan.
Losartan (Cozaar)
Berberine might reduce the therapeutic effects of losartan by decreasing its conversion to its active form.
Preliminary clinical research suggests that berberine can inhibit cytochrome P450 2C9 (CYP2C9) activity and reduce metabolism of losartan.
Metformin (Glucophage)
Theoretically, berberine might increase the therapeutic and adverse effects of metformin.
In vitro and animal studies show that berberine can increase the systemic exposure and half-life of metformin, potentially increasing metformin's effects and side effects. This interaction seems to be most apparent when berberine is administered 2 hours prior to metformin. Taking berberine and metformin at the same time does not appear to increase systemic exposure to metformin.
Midazolam (Versed)
Berberine can reduce metabolism of midazolam, which might increase the risk of severe adverse effects.
Preliminary clinical research shows that berberine can inhibit cytochrome P450 3A4 (CYP3A4) activity and reduce metabolism of midazolam.
Pentobarbital (Nembutal)
Berberine might increase the sedative effect of pentobarbital.
Evidence from animal research shows that berberine can prolong pentobarbital-induced sleeping time. Theoretically, combining berberine and pentobarbital might increase the sedative effects of pentobarbital.
Tacrolimus (Prograf)
Berberine has been associated with increased blood levels of tacrolimus.
In a 16-year-old patient with idiopathic nephrotic syndrome who was being treated with tacrolimus 6.5 mg twice daily, intake of berberine 200 mg three times daily increased the blood concentration of tacrolimus from 8 to 22 ng/mL. Following a reduction of the tacrolimus dose to 3 mg daily, blood levels of tacrolimus decreased to 12 ng/mL.
Acetazolamide
Laboratory studies and initial clinical findings suggest that berberine has the potential to increase acetazolamide concentrations in the body. More research is needed to confirm this interaction.
