HelloPharmacist Scorecard of Berberine by Solaray
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 supplement contains two active ingredients: berberine hydrochloride (a plant alkaloid) and Oregon grape (a botanical source of berberine). Berberine is the primary active compound and the main driver of this product's effects.
The supplement also contains cellulose as an inactive ingredient.
Does it work?
Moderate evidence
Berberine has been rated possibly effective for high cholesterol (hyperlipidemia), polycystic ovary syndrome (PCOS), high blood pressure (hypertension), and type 2 diabetes based on clinical evidence. It is also possibly effective against Helicobacter pylori infection.
Oregon grape is rated possibly effective for psoriasis but has insufficient evidence to rate its use for eczema, acid reflux (GERD), or peptic ulcers.
How safe is it?
Well-documented data
Taken by mouth, berberine is generally well tolerated short-term but commonly causes digestive upset—abdominal pain, bloating, constipation, diarrhea, gas, nausea, and vomiting. It may also cause dizziness, drowsiness, fatigue, and headache.
The safety data advises against berberine during pregnancy because it may cross the placenta and has been linked to harm in newborns. Do not use while breastfeeding because berberine passes into breast milk.
Topically, Oregon grape may cause itching, burning, and skin irritation in some people.
Meds to double-check
Major interaction found
Before taking this product, have your pharmacist check cyclosporine (highest concern), blood thinners and antiplatelet drugs, blood pressure medications, diabetes drugs, sedating medications, and any drug metabolized by the liver enzymes CYP2D6, CYP2C9, or CYP3A4. Berberine can raise levels of many medications in these categories.
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 is worth considering if you're managing high cholesterol, PCOS, high blood pressure, or diabetes—and your pharmacist or doctor has cleared it with your medication list. Because this supplement affects how your liver breaks down many drugs, check every prescription and over-the-counter medication you take before starting.
If you're pregnant, planning pregnancy, or breastfeeding, talk with your pharmacist or doctor first.

Berberine by Solaray Drug Interactions
HelloPharmacist Interaction Report
Solaray Berberine is a two-ingredient supplement that carries significant interaction potential with a number of medications.
The most serious concern is cyclosporine (Neoral, Sandimmune)—a Major severity interaction. Berberine can slow how your body breaks down cyclosporine, raising its blood levels and risk of side effects.
This happens because berberine inhibits an enzyme (CYP3A4) that cyclosporine depends on for metabolism.
Read the full breakdown — every affected drug type, severity by severity
Berberine and Oregon grape also interact with several other drug types at Moderate severity. These include blood thinners and antiplatelet drugs (which increase bleeding risk), blood pressure medications (which may lower your pressure further), diabetes drugs (which may raise the risk of low blood sugar), and sedating medications (which may make you drowsier).
Additionally, both ingredients can slow the breakdown of drugs metabolized by three major liver enzymes—CYP2D6, CYP2C9, and CYP3A4—potentially raising their blood levels.
Additionally, Oregon grape also has a separate Moderate interaction with cyclosporine. Altogether, these interactions span 1,204 individual medications.
Because the enzyme-inhibition effects are broad, check your exact medications with the search tool on this page before starting.

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.
