Tinospora Cordifolia and Acetaminophen, Caffeine, Dihydrocodeine

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

Why Are There 2 Interactions?

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

Moderate

CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES

1 of 2

Why this applies to Acetaminophen, Caffeine, Dihydrocodeine

Acetaminophen, Caffeine, Dihydrocodeine falls under CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES — the group Tinospora Cordifolia interacts with.

Theoretically, Tinospora cordifolia might increase levels of drugs metabolized by CYP2D6.
In vitro research shows that Tinospora cordifolia extract inhibits CYP2D6 at high concentrations. However, this interaction has not been reported in humans.
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 explains PharmD, Clinical Pharmacist

Here's the wrinkle with this combo product: the dihydrocodeine part is a prodrug. Your body uses an enzyme called CYP2D6 to convert it into its stronger, active painkilling form. Lab studies (only in test tubes, at high concentrations) hint that Giloy might slow that same enzyme down. If that happened in real life, you could actually get less pain relief from the dihydrocodeine, not more, since less of it would be activated.

That said, this has never been reported in actual people, so I wouldn't lose sleep over it. The acetaminophen and caffeine pieces aren't really affected here. Still, since Giloy itself has been tied to rare liver problems and acetaminophen is also hard on the liver, it's worth a quick chat with your pharmacist or doctor before pairing them.

CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES

2 of 2

Acetaminophen, Caffeine, Dihydrocodeine also falls under CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES.

Theoretically, Tinospora cordifolia might increase levels of drugs metabolized by CYP1A2.
In vitro research shows that Tinospora cordifolia extract inhibits CYP1A2 at high concentrations. However, this interaction has not been reported in humans.
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 combo pill carries three different ingredients, and the part that matters here is the caffeine. Your body clears caffeine using an enzyme called CYP1A2. In lab dishes, Tinospora cordifolia (Giloy) appears to slow that enzyme down, which could let caffeine linger longer. If that happened, you might notice more of caffeine's usual effects: jitteriness, a racing heart, trouble sleeping, or feeling wired.

Here's the honest part. This is only seen in test-tube research at high concentrations, never reported in real people, so it's mostly theoretical. The acetaminophen and dihydrocodeine pieces aren't the main concern with this enzyme. Still, since Giloy has been linked to liver injury and acetaminophen also stresses the liver, I'd check with your pharmacist or doctor before pairing them.

From our pharmacist’s overview on the Acetaminophen, Caffeine, Dihydrocodeine page

“Anything else that sedates you is the headline risk with this combination painkiller. Panlor and DHC Plus pair acetaminophen and caffeine with the opioid dihydrocodeine, and 78 of the 303 supplements on file, kava and even beer or wine among them, can deepen the opioid's drowsiness and, at the extreme, dangerously slow breathing.”
