These two interact in 3 distinct ways. Each one is explained separately below.
Why Are There 3 Interactions?
Propolis interacts with whole categories of medication. Acetaminophen, Chlorpheniramine, Phenylephrine, Salicylamide falls into 3 of those categories, so it can interact with Propolis in 3 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).
CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES
1 of 3Why this applies to Acetaminophen, Chlorpheniramine, Phenylephrine, Salicylamide
Acetaminophen, Chlorpheniramine, Phenylephrine, Salicylamide falls under CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES — the group Propolis interacts with.
In vitro research shows that propolis extract can inhibit CYP1A2. However, animal research shows that propolis extract does not significantly affect CYP1A2 activity when administered to rats at doses up to 250 mg/kg. It is postulated that the constituents of propolis that inhibit CYP1A2 in vitro do not have significant effects in vivo due to low bioavailability and hepatic first-pass effect. This effect has not been reported in humans.
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.
Here's the bottom line on taking propolis with this cold and allergy combo (Rhinogesic). The concern is that propolis, in test-tube studies, can slow down a liver enzyme called CYP1A2. If that happened in your body, ingredients cleared by that pathway could build up a bit, which in theory might mean more drowsiness or dry mouth from the chlorpheniramine, or a little extra acetaminophen lingering.
But honestly, this is very weak evidence. It's only been seen in lab dishes, and animal studies showed propolis didn't meaningfully change this enzyme when actually swallowed, likely because not much gets absorbed. No real cases have been reported in people. Normal propolis use is unlikely to cause trouble, but if you take high doses, just mention it to your pharmacist.

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES
2 of 3Acetaminophen, Chlorpheniramine, Phenylephrine, Salicylamide also falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES.
Some in vitro research shows that propolis extract can inhibit CYP3A4; however, other in vitro research shows that propolis has no effect on CYP3A4 activity. Furthermore, animal research shows that propolis extract does not significantly affect CYP3A4 activity when administered to rats at doses up to 250 mg/kg. It is postulated that the constituents of propolis that might in inhibit CYP3A4 in vitro do not have significant effects in vivo due to low bioavailability and hepatic first-pass effect. This effect has not been reported in humans.
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.
Here's the gist with this multi-ingredient cold and pain combo (Rhinogesic). The concern on file is that propolis might slow down a liver enzyme called CYP3A4, which helps clear certain medicines. If that enzyme is blocked, a drug it processes could build up a bit more than usual. None of these ingredients are prodrugs, so in theory you'd see slightly stronger effects, think more drowsiness or dry mouth from the chlorpheniramine, or a touch more jitteriness or raised blood pressure from the phenylephrine.
That said, I wouldn't lose sleep over this one. The evidence is very weak, coming only from lab and animal studies, and it has never been reported in real people. Normal supplement amounts are unlikely to matter. Still, run it by your pharmacist if you take propolis daily.

CYTOCHROME P450 2E1 (CYP2E1) SUBSTRATES
3 of 3Acetaminophen, Chlorpheniramine, Phenylephrine, Salicylamide also falls under CYTOCHROME P450 2E1 (CYP2E1) SUBSTRATES.
In vitro research shows that propolis can inhibit CYP2E1. This effect has not been reported in humans.
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.
This combination product (sold as Rhinogesic and Rhinogesic JR) includes acetaminophen, which is the piece that matters here. A small part of acetaminophen gets handled by a liver enzyme called CYP2E1. In test-tube studies, propolis seems to slow that enzyme down. The theory is that if CYP2E1 is blocked, slightly more acetaminophen could hang around, which over time might mean a bit more strain on the liver.
I want to be honest with you, though: this is only lab data, and it has not actually been seen in people. So for most folks taking the occasional cold and pain combo, this is more theoretical than something to lose sleep over. Just keep your acetaminophen within recommended daily limits, and check with your pharmacist if you use propolis regularly or have any liver concerns.

From our pharmacist’s overview on the Acetaminophen, Chlorpheniramine, Phenylephrine, Salicylamide page
“I would slow down before pairing supplements with Rhinogesic (acetaminophen, chlorpheniramine, phenylephrine, salicylamide). Each part of this cold remedy opens a different door to trouble, so supplements can collide with it from several directions at once.”
