| Substance | Interaction | What happens |

| St. John's Wort | Conflict | St. John's Wort products high in hyperforin induce CYP3A, and methylprednisolone is a CYP3A-sensitive steroid. This may lower methylprednisolone... details → |
| Schisandra | Caution | Schisandra extract has human evidence of inhibiting CYP3A activity, and methylprednisolone exposure is highly sensitive to CYP3A inhibition.... details → |
| Strontium | Caution | Methylprednisolone can cause bone loss when used repeatedly or chronically. Strontium supplements can raise apparent DXA bone density independent of... |
| Calcium | Synergy | Like all glucocorticoids, methylprednisolone reduces calcium absorption and increases bone loss. Calcium supplementation is recommended for patients... details → |
| Potassium | Synergy | High-dose or pulse methylprednisolone can disturb potassium handling and has been associated with clinically relevant rhythm concerns in vulnerable... details → |
| Vitamin D2 | Synergy | Chronic methylprednisolone exposure can reduce bone density and raise fracture risk. Vitamin D2 can help maintain vitamin D status and calcium... details → |
| Vitamin D3 | Synergy | Methylprednisolone accelerates vitamin D catabolism. Vitamin D supplementation is standard care for glucocorticoid-induced osteoporosis prevention. |
What methylprednisolone 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 |
|---|---|---|---|---|
| Calcium | Significant | Glucocorticoids reduce intestinal calcium absorption, increase urinary calcium loss, and accelerate bone resorption. | Calcium | Serum calcium or bone density trend |
| Vitamin D | Moderate | Glucocorticoids impair activation and signaling of vitamin D, reducing calcium absorption and bone support. | Vitamin D3 | 25-OH vitamin D |
| Potassium | Moderate | Systemic corticosteroids can promote potassium loss or shifts in susceptible patients, especially at higher doses or with other hypokalemia risks;... | Clinician-guided potassium repletion if serum potassium is low | Serum potassium + kidney function |
| Magnesium | Moderate | Chronic corticosteroid use can increase urinary magnesium losses and worsen low magnesium status. | Magnesium Glycinate | Serum magnesium or RBC magnesium |

What interacts with Methylprednisolone?
In the NutriStack database, Methylprednisolone has 7 documented interactions. The most notable include St. John's Wort, Schisandra, Strontium, Calcium, and Potassium. Check any specific combination before taking it and confirm with your prescriber.
Which substances should I avoid with Methylprednisolone?
Methylprednisolone is flagged against 1 substance in the database, including St. John's Wort. These pairings carry a higher risk and should be reviewed with a clinician before combining.
Does Methylprednisolone deplete any nutrients?
Methylprednisolone is associated with lowering Calcium, Vitamin D, Potassium, and Magnesium with prolonged use. Useful biomarkers to monitor include Serum calcium or bone density trend, 25-OH vitamin D, and Serum potassium + kidney function. Ask your prescriber before adding any replacement supplement.
Is it safe to take St. John's Wort with Methylprednisolone?
NutriStack classifies the St. John's Wort and Methylprednisolone pairing as conflict: St. John's Wort products high in hyperforin induce CYP3A, and methylprednisolone is a CYP3A-sensitive steroid. This may lower methylprednisolone exposure and reduce... Avoid starting St. John's Wort during methylprednisolone therapy unless your prescriber approves. If you already take it, do not stop or start it... Always confirm with your prescriber.
