Kava and Medications: What You Need to Know About Interactions and Risks
When you take kava, a traditional herbal remedy from the Pacific Islands used for anxiety and relaxation. Also known as Piper methysticum, it works on the brain’s GABA receptors to calm nerves—but that same mechanism can clash dangerously with prescription drugs. Many people use kava to ease stress or sleep better, but if you’re on medications for anxiety, depression, epilepsy, or high blood pressure, mixing them could be risky.
Kava doesn’t just sit quietly in your system. It affects your liver’s ability to break down other drugs, which means medications like prednisolone, a corticosteroid used for inflammation and allergies, or methadone, a painkiller and addiction treatment that already carries heart rhythm risks, can build up to unsafe levels. Even common sleep aids like diphenhydramine, the active ingredient in Unisom and many OTC sleep products, can amplify drowsiness and dizziness when taken with kava. This isn’t theoretical—there are documented cases of liver damage and abnormal heart rhythms in people who combined kava with these drugs.
It’s not just about what you’re taking—it’s about what your body can handle. People with existing liver conditions, older adults, or those on multiple medications are at higher risk. If you’re using kava alongside any prescription or over-the-counter drug, you’re playing with fire unless you know the rules. The good news? You don’t have to guess. The posts below break down real cases, compare kava with other herbal options like boswellic acid, and explain exactly which medications to avoid. Whether you’re managing anxiety, chronic pain, or sleep issues, you’ll find clear, no-fluff advice on how to stay safe without giving up what helps you feel better.
