Elecampane and Valbenazine Tosylate

Here is the interaction we found between these two, with the evidence behind it.

Moderate

CNS DEPRESSANTS

Why this applies to Valbenazine Tosylate

Valbenazine Tosylate falls under CNS DEPRESSANTS — the group Elecampane interacts with.

Theoretically, elecampane may cause additive sedative effects when taken with CNS depressants.
Elecampane might have sedative effects.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist with Ingrezza (valbenazine) and elecampane. Valbenazine can already make some people feel drowsy or tired. Elecampane is thought to have mild sedative properties of its own, so pairing the two could, in theory, leave you feeling sleepier, foggier, or less alert than usual.

I want to be honest about the strength of this concern: it's theoretical, based on how the herb behaves rather than real cases in people. The science behind elecampane is thin overall. Small culinary or tea amounts are less likely to matter than concentrated supplement capsules. Still, if you notice extra drowsiness, take it easy with driving and check in with your pharmacist or doctor before combining them.

About Elecampane

What is Elecampane?

Elecampane
  • Cough and bronchitis
  • Asthma symptoms
  • Loosening mucus (expectorant)
  • Digestive upset
  • Intestinal worms (traditional)

Elecampane is a traditional herb used mainly for coughs and other respiratory complaints, and as a bitter for digestion. Modern human evidence is very limited, so it should be seen as a folk remedy rather than a proven treatment. Talk to your pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.

About Valbenazine

What Is Valbenazine Used For?

Brand name: Ingrezza

Valbenazine — sold as Ingrezza and INGREZZA Sprinkle — is approved for two conditions in adults. The first is tardive dyskinesia, a movement disorder that causes uncontrolled, repetitive facial or body movements, often brought on by long-term use of certain psychiatric medications. The second is chorea associated with Huntington's disease, which refers to the involuntary, dance-like jerking movements that are a hallmark of that condition.

Both Ingrezza and INGREZZA Sprinkle are approved for both of these uses.
