| Drug | Severity | Description |
|---|---|---|
| Losartan | Moderate | Berberine may increase losartan levels and its active metabolite, potentially enhancing blood pressure effects. |
| Cyclosporine | Severe | Berberine significantly increases cyclosporine blood levels (by nearly 100% in one study), increasing risk of toxicity. |
| Dextromethorphan | Moderate | Berberine may increase dextromethorphan blood levels by inhibiting its metabolism. |
| Metformin | Moderate | Berberine has similar blood sugar-lowering mechanisms to metformin. Combining them may cause excessive blood sugar reduction (hypoglycemia). |
