Alprazolam is used to treat anxiety and panic disorder, and is in a family of drugs known as benzodiazepines.
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.1 Further study is needed to determine if vinpocetine would be a helpful adjunct to use of benzodiazepines, or alprazolam specifically.
Kava (Piper methysticum) is an herb used to treat anxiety disorder. One individual who took alprazolam and kava together, along with two other medications (cimetidine and terazosin) was hospitalized in a lethargic and disoriented condition.3 Further research is needed to determine whether the combination of kava and alprazolam produces an adverse interaction. However, individuals should not take alprazolam and kava together unless supervised by a doctor.
