| Substance | Interaction | What happens |
|---|---|---|
| Grapefruit Juice | Contraindicated | Grapefruit juice inhibits intestinal CYP3A4 and can substantially increase lovastatin exposure, raising myopathy and rhabdomyolysis risk. details → |
| St. John's Wort | Conflict | St. John's Wort can induce CYP3A4 and P-glycoprotein, which may lower exposure to CYP3A4-metabolized statins. Human data show a major reduction in... details → |
| Berberine | Caution | Lovastatin is highly dependent on CYP3A4 metabolism, and berberine has human evidence of inhibiting CYP3A4 after repeated dosing. This creates a... |
| Vitamin B3 | Caution | High-dose Vitamin B3 as niacin can add muscle, liver, and glucose-related adverse effects to statin therapy. Large statin-era niacin trials found no... details → |
| Coenzyme Q10 | Synergy | Lovastatin can lower CoQ10 production by blocking the mevalonate pathway. CoQ10 depletion is a plausible contributor to statin-associated myalgia,... details → |
| Coenzyme Q10 Ubiquinol | Synergy | Lovastatin can reduce endogenous CoQ10 synthesis, and ubiquinol is the reduced form of CoQ10 used in many supplements. Restoring CoQ10 status may... details → |
What lovastatin can deplete.
Nutrients this medication is associated with lowering over time, with the mechanism, a suggested replacement where one applies, and the biomarker to monitor. Discuss any replacement with your prescriber first.
| Nutrient | Severity | How it happens | Replace with | Monitor |
