Deanol and Hydrocodone/Chlorpheniramine

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

Minor

ANTICHOLINERGIC DRUGS

Why this applies to Hydrocodone/Chlorpheniramine

Hydrocodone/Chlorpheniramine falls under ANTICHOLINERGIC DRUGS — the group Deanol interacts with.

Theoretically, deanol might decrease the effectiveness of anticholinergic drugs.
Deanol is thought to increase acetylcholine levels.
Severity Minor Likelihood Unlikely Evidence D

Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans..

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

The chlorpheniramine part of Tussionex is an antihistamine that works partly by blocking acetylcholine, the brain and body chemical that deanol may help raise. So in theory, deanol could push back against chlorpheniramine a little and make it slightly less effective at drying up a runny nose or calming a cough. The hydrocodone (the narcotic part) isn't really involved here.

The good news: this is a theoretical concern only, based on how these compounds work on paper, not on real cases of people running into trouble. It's rated minor and unlikely. I wouldn't lose sleep over it, but since Tussionex is a controlled cough medicine, it's always smart to run any new supplement past your pharmacist or doctor first.

From our pharmacist’s overview on the Hydrocodone/Chlorpheniramine page

“Tussionex (hydrocodone with chlorpheniramine) pairs an opioid with a sedating antihistamine, so anything that deepens drowsiness or slows breathing is a genuine hazard, and 78 of the 258 supplements on file do exactly that. Alcohol in any form tops that group, and kava carries a major rating for the same reason.”

About Deanol

What is Deanol?

Deanol
  • Memory and focus
  • Mood and mental clarity
  • ADHD-type symptoms
  • Skin firmness (topical)
  • General brain health

Deanol (DMAE) is a compound related to choline that is marketed for memory, focus, and mood, but solid human evidence for most of these uses is limited or mixed. It can cause side effects in some people, and it should be avoided in pregnancy and breastfeeding because its safety is not established. Talk to your pharmacist or doctor before trying it.
