Bitter Yam and Chlorpheniramine, Hydrocodone, Pseudoephedrine

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, Hydrocodone, Pseudoephedrine and Bitter Yam 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.

From our pharmacist’s overview on the Chlorpheniramine, Hydrocodone, Pseudoephedrine page

“Tussend combines three drugs in one cough medicine, the opioid hydrocodone, the antihistamine chlorpheniramine, and the decongestant pseudoephedrine, so supplements can collide with it from several directions.

About Bitter Yam

What is Bitter Yam?

Bitter Yam
  • Blood sugar support
  • Digestive complaints
  • Traditional food source
  • Wound and skin care (folk use)

Bitter yam is a wild African yam used traditionally as both food and folk medicine, often for blood sugar and digestion. Scientific evidence in humans is very limited, and some bitter yam species can be toxic if not properly prepared. Talk to a pharmacist or doctor before using it as a supplement.

Dioscorea dumetorum · Dioscoreaceae · Tuber (root) · Cooked tuber, dried powder, traditional preparations

An interaction check asks whether these two react with each other — it does not ask whether Bitter Yam is a good idea for someone in your situation. Here is what our Bitter Yam record says about it on its own.

Bitter Yam: dosing

There is no established, standardized dose of bitter yam as a supplement. Traditional use varies widely and depends on how the tuber is prepared.If you choose to use a commercial product, follow the directions on the label and do not take more than recommended.
