Elecampane and Nelarabine

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

Moderate

CNS DEPRESSANTS

Why this applies to Nelarabine

Nelarabine 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, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the thing to know about this pairing: nelarabine is a chemotherapy drug, and one of its well-known side effects is hitting the nervous system. It can cause drowsiness, sleepiness, confusion, dizziness, and trouble with balance or coordination. Elecampane, an herbal remedy for coughs, is thought to have mild sedative (calming) effects of its own.

So the concern is simply additive: if elecampane adds a little extra drowsiness on top of what nelarabine already does, you might feel more tired or foggy than usual. I want to be honest though, this is a theoretical interaction based on how the herb may act, not on real-world reports. Even so, because nelarabine is serious chemo, please clear any supplement with your oncology team first.

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.
