Kava can interact with other substances, and it's worth understanding those interactions before combining kava with anything else.
Alcohol
We don't recommend combining kava with alcohol. Both can affect coordination and judgment, and combining them may increase those effects unpredictably.
Sedatives and other central-nervous-system medications
Kava may have additive effects with prescription sedatives, sleep medications, and similar drugs. If you take any medication in this category, talk to a doctor or pharmacist before using kava — this is one of the more important interactions to take seriously.
Medications processed by the liver
Kavalactones can affect certain liver enzymes involved in metabolizing a range of pharmaceuticals. If you take prescription medication of any kind, ask a doctor or pharmacist whether an interaction with kava is a concern for your specific medication, rather than assuming it's fine.
What we're not going to do
This article previously described tudei — non-Beverage Grade — kava as an alternative product some people might prefer for stronger effects, and pointed toward where to buy it. We don't stand behind that. Tudei kava is not something we sell, and we're not going to describe it as a legitimate purchasing option.
