Coriander and Hydrocodone, Pseudoephedrine, Chlorpheniramine

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Coriander interacts with whole categories of medication. Hydrocodone, Pseudoephedrine, Chlorpheniramine falls into 2 of those categories, so it can interact with Coriander in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

CNS DEPRESSANTS

1 of 2

Why this applies to Hydrocodone, Pseudoephedrine, Chlorpheniramine

Hydrocodone, Pseudoephedrine, Chlorpheniramine falls under CNS DEPRESSANTS — the group Coriander interacts with.

Theoretically, coriander might cause additive sedative effects when taken with CNS depressants.
Evidence from animal research suggests that coriander fruit extract has 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

This combination medicine has two ingredients that already make people drowsy: hydrocodone (an opioid cough and pain reliever) and chlorpheniramine (a sedating antihistamine). The concern here is simple addition. Animal studies hint that coriander may have a mild calming, sedative effect of its own, so in theory it could pile onto the sleepiness you already get from this product. That might mean more grogginess, dizziness, or slowed thinking.

Honestly, this is a theoretical worry based only on animal research, and the small amount of coriander or cilantro you eat in food is very unlikely to matter. Concentrated extracts or essential oils are a different story. Don't change anything on your own, but check with your pharmacist or doctor before using strong coriander supplements alongside Zutripro.

PHOTOSENSITIZING DRUGS

2 of 2

Hydrocodone, Pseudoephedrine, Chlorpheniramine also falls under PHOTOSENSITIZING DRUGS.

Theoretically, coriander might increase the risk of photosensitivity when taken with photosensitizing drugs.
Evidence from in vitro research suggests that coriandrin, a constituent of coriander, has photosensitizing 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 short version on pairing coriander with Zutripro (the combo of hydrocodone, pseudoephedrine, and chlorpheniramine). This particular concern isn't about how the medicine is broken down or how strong it feels. Instead, it's a possible photosensitivity issue, meaning your skin could become a little more prone to sunburn. A coriander compound called coriandrin has shown sun-sensitizing effects, but only in lab dish studies, not in real people.

So please don't be alarmed. This is theoretical and based on weak, anecdotal evidence. Normal cooking amounts of cilantro are very unlikely to matter. If you use concentrated coriander extracts or oils and notice you're burning more easily, use sunscreen and check in with your pharmacist or doctor.
