We found no known interaction between Elecampane and Chlorpheniramine Maleate, Dextromethorphan Hydrobromide in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.
Elecampane and Chlorpheniramine Maleate, Dextromethorphan Hydrobromide
We checked these two against our interaction database. Here is what we found.
No Known Interaction Found
We did not find a documented interaction between Chlorpheniramine Maleate, Dextromethorphan Hydrobromide and Elecampane in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.
If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.
Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

About Elecampane
What is 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.
Inula helenium · Asteraceae · Roots and rhizomes · Tea, tincture, dried root, capsules, lozenges, syrup
An interaction check asks whether these two react with each other — it does not ask whether Elecampane is a good idea for someone in your situation. Here is what our Elecampane record says about it on its own.
