Library Home > Safetychecker by Drug Name > Risperidone RISPERIDONE Introduction Safetychecker summary Vitamin interactions Herb interactions Food interactions References Visit The Healthy Living Bookshelf: 21 Online Health Books From Rodale Risperidone is used to manage symptoms associated with psychotic disorders, especially schizophrenia. Safetychecker Summary for Risperidone (for details about the summarized interactions, read the full article) May be Beneficial: Side effect reduction/prevention—Taking these supplements may help reduce the likelihood and/or severity of a potential side effect caused by the medication. Vitamin B6 Vitamin E Check: Other—Before taking any of these supplements or eating any of these foods with your medication, read this article in full for details. Licorice White Peony Depletion or interference None known Supportive interaction None known Reduced drug absorption/bioavailability None known Adverse interaction None known Interactions with Dietary Supplements Vitamin E and Vitamin B6 Vitamin E along with vitamin B6 was used to treat a side effect of risperidone called neuroleptic malignant syndrome in a 74-year-old woman, and results were encouraging.1 However, whether vitamin E and vitamin B6 supplementation might help prevent this condition in people taking risperidone is unknown. Lithium Lithium is a mineral present in large amounts in some medications, and may be included in some mineral supplements. The combination of lithium and risperidone has produced unwanted side effects such as delirium, confusion, and fever.2 3 Smaller amounts of lithium are available in some nutritional supplements, but it is not known whether these amounts are enough to cause a problem in individuals taking risperidone. Interactions with Herbs Licorice (Glycyrrhiza radix) and White peony (Paeoniae radix) An Oriental herb formula containing Glycyrrhiza radix (licorice root) and Paeoniae radix (white peony root) successfully restored menses in a 28-year-old woman who had developed amenorrhea (lack of menstruation) while taking risperidone.4 Discontinuation of these herbs while the woman continued taking risperidone again led to disruption of her menses. Controlled research is needed to determine whether supplementation with licorice and peony might help prevent amenorrhea in women taking risperidone. Interactions with Foods and Other Compounds Food Risperidone oral solution should be mixed in half a glass of water, coffee, orange juice, or low-fat milk and immediately consumed.5 It should not be mixed with cola or tea.6 Alcohol Alcohol increases the breakdown of many antipsychotic drugs.7 More research is necessary to determine if alcohol consumption might lower blood levels of risperidone.
