Summary of Interactions with Vitamins, Herbs, & Foods
Replenish Depleted Nutrients
Copper and Zinc
In various studies of children treated with valproic acid for epilepsy compared with control groups, serum zinc levels remained normal or decreased, serum copper levels remained normal or decreased, and red blood cell zinc levels were decreased. The importance of these changes and how frequently they occur remain unclear.The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.
Reduce Side Effects
In a preliminary trial, an extract of periwinkle called vinpocetine was shown to produce minor improvements in short-term memory among people taking flunitrazepam, a benzodiazepine. Further study is needed to determine if vinpocetine would be a helpful adjunct to use of benzodiazepines.The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.
Potential Negative Interaction
Kava (Piper methysticum) is an herb used to treat anxiety disorder. One individual who took a benzodiazepine (alprazolam) and kava together, along with two other medications (cimetidine and terazosin) was hospitalized in a lethargic and disoriented condition.2 Further research is needed to determine whether the combination of kava and benzodiazepines produces an adverse interaction. However, individuals should not take benzodiazepines and kava together unless supervised by a doctor.The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.
St. John's Wort
In a study of healthy volunteers, administration of St. John's wort (Hypericum perforatum) along with alprazolam decreased blood levels of alprazolam, compared with the levels when alprazolam was taken by itself.3 Individuals taking alprazolam should not take St. John's wort without supervision by a doctor.
