It is not known exactly what to expect from an overdose, although it is reasonable to expect that any of the usual kava side effects could occur (but perhaps more severely).
If you think you may have taken too much, seek medical attention immediately.

Refer to the label of your individual product for information on how to best store kava. Keep kava and all other medications or supplements out of the reach of children.
