Propolis + Aspirin, Butalbital, Caffeine, Codeine Phosphate
Aspirin, Butalbital, Caffeine, Codeine Phosphate brand name: Fiorinal w/ Codeine.
Aspirin, Butalbital, Caffeine, Codeine Phosphate falls into 4 drug categories that Propolis can interact with; the most serious is rated moderate. Theoretically, high doses of propolis might increase blood levels of drugs metabolized by CYP2D6.

These two interact in 4 distinct ways. Each one is explained separately below.
Why Are There 4 Interactions?
Propolis interacts with whole categories of medication. Aspirin, Butalbital, Caffeine, Codeine Phosphate falls into 4 of those categories, so it can interact with Propolis in 4 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).
CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES
1 of 4Why this applies to Aspirin, Butalbital, Caffeine, Codeine Phosphate
Aspirin, Butalbital, Caffeine, Codeine Phosphate falls under CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES — the group Propolis interacts with.
In vitro research shows that propolis extract can inhibit CYP2D6. However, animal research shows that propolis extract does not significantly affect CYP2D6 activity when administered to rats at doses up to 250 mg/kg. It is postulated that the constituents of propolis that inhibit CYP2D6 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 wrinkle with this combo. The codeine in Fiorinal with Codeine is actually a prodrug, meaning your body has to switch it on using a liver enzyme called CYP2D6 before it can relieve pain. Lab studies hint that propolis might block that same enzyme. If that happened in real life, it could mean less of your codeine gets turned into its active form, so you might get weaker pain relief rather than more side effects.
The good news: this is only a theoretical, test-tube finding. Animal studies didn't show a real effect, and it has never been reported in people. Normal propolis use is unlikely to matter much, but if you take concentrated doses regularly, mention it to your pharmacist or doctor just to be safe.

CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES
2 of 4Aspirin, Butalbital, Caffeine, Codeine Phosphate also falls under CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES.
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.
In this combination product (Fiorinal with Codeine), the piece that touches propolis is mostly the caffeine, which your liver clears using an enzyme called CYP1A2. In test-tube studies, propolis can slow that enzyme down. If that happened in the body, caffeine could hang around longer and you might feel jittery, have a racing heart, trouble sleeping, or an upset stomach.
Here's the reassuring part: this is only seen in lab dishes, not in people. Animal studies didn't show a real effect, likely because propolis isn't absorbed well. So I wouldn't lose sleep over it. Still, if you take concentrated propolis supplements and notice extra caffeine-like buzziness, mention it to your pharmacist or doctor.

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES
3 of 4Aspirin, Butalbital, Caffeine, Codeine Phosphate 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 Fiorinal with Codeine and propolis. This combo pill has several ingredients, and the one that leans on the CYP3A4 enzyme is the butalbital (the barbiturate that eases tension headaches). In test-tube studies, propolis sometimes blocked CYP3A4, which could theoretically slow the breakdown of butalbital and let a bit more linger in your system. In practice that might mean feeling extra drowsy, foggy, or unsteady.
That said, I want to keep this in perspective. The signal comes only from lab and animal work, and even rat studies didn't show a real effect. Nothing like this has been reported in people, so I wouldn't lose sleep over it. Still, since this medicine already causes sedation, mention your propolis use to your pharmacist or doctor to be safe.

ANTICOAGULANT/ANTIPLATELET DRUGS
4 of 4Aspirin, Butalbital, Caffeine, Codeine Phosphate also falls under ANTICOAGULANT/ANTIPLATELET DRUGS.
In vitro research shows that propolis water extract and the propolis constituent, caffeic acid phenethyl ester, can inhibit platelet aggregation. Additionally, evidence from an animal model shows that taking propolis in addition to warfarin decreases INR, suggesting that propolis can decrease the effectiveness of warfarin.
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 piece that matters for Fiorinal with Codeine: the aspirin in it already thins your blood by blocking platelets, the tiny cells that help you clot. Propolis contains compounds (like CAPE) that, in lab dish studies, also slow platelets down. Stacked together, the theory is that they could nudge your bleeding risk a little higher, meaning easier bruising, nosebleeds, or stomach irritation that's slower to stop.
I want to be honest about the strength of this, though. It comes from test-tube and animal research, not real patients, so it's more of a caution than a proven problem. Everyday food or throat-spray amounts are unlikely to matter much. Before adding a concentrated propolis supplement, just run it by your pharmacist or doctor, especially if you bruise easily or take other blood thinners.

From our pharmacist’s overview on the Aspirin, Butalbital, Caffeine, Codeine Phosphate page
“Fiorinal with Codeine packs four active drugs into one capsule, and I would treat its supplement list with genuine wariness rather than a quick skim. The aspirin component is why roughly half of the 398 ingredients on file raise bleeding risk, while the codeine and butalbital explain a second large cluster that deepens sedation, someti…”

Propolis is a natural, resin-like substance made by bees that has antimicrobial and anti-inflammatory properties in lab studies. Early research suggests it may help with cold sores, mouth sores, and minor wounds, but high-quality evidence is limited for most uses. It is generally well tolerated, but allergic reactions can occur, especially in people allergic to bee products.
