Applies to:Vitamin D3 (cholecalciferol) and oxcarbazepine
MONITOR: Coadministration with CYP450 inducers such as rifampin, isoniazid, barbiturates, and certain anticonvulsants may decrease the pharmacologic effects of vitamin D analogs. These agents are thought to induce the hepatic conversion of vitamin D to inactive metabolites and have been shown to reduce circulating levels of active vitamin D, sometimes accompanied by reduced serum calcium and increased parathyroid hormone levels. Patients on long-term anticonvulsant therapy have occasionally developed osteomalacia, presumably due to interference with vitamin D and calcium metabolism. There have also been isolated reports of patients who responded poorly to vitamin D supplements during treatment with phenytoin and/or primidone.
MANAGEMENT: Patients receiving vitamin D analogs with CYP450 inducers should be monitored for potentially reduced vitamin D effects. Dosage adjustments may be necessary.

Drug Interaction Classification
The classifications below are a guideline only. The relevance of a particular drug interaction to a specific patient is difficult to determine using this tool alone given the large number of variables that may apply.
| Major | Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit. |
| Moderate | Moderately clinically significant. Usually avoid combinations; use it only under special circumstances. |
| Minor | Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan. |
