Tinospora Cordifolia and Acetaminophen, Codeine

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, Codeine 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, Codeine

Acetaminophen, Codeine 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.

Here's the wrinkle with this combo: codeine is a prodrug. Your body needs an enzyme called CYP2D6 to turn codeine into morphine, which is what actually relieves your pain. Tinospora cordifolia (Giloy) has shown in lab dishes that it can block CYP2D6, but only at high concentrations, and this has never been seen in real people.

If it did slow that enzyme down, you might convert less codeine into morphine, so the pain relief from your Tylenol with Codeine could feel weaker. This is a theoretical concern based only on test-tube data, so I wouldn't panic. Still, if you're using Giloy and notice your pain isn't well controlled, mention it to your pharmacist or doctor.

CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES

2 of 2

Acetaminophen, Codeine 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

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the honest picture for your Tylenol with Codeine. The concern on file is that Giloy (Tinospora cordifolia) might block an enzyme called CYP1A2. The catch is that codeine isn't really cleared by CYP1A2, and the acetaminophen part only sends a small amount through that pathway. So in plain terms, this particular interaction is unlikely to cause much trouble with this medicine.

I'd also stress that this is only a theoretical finding from lab dishes at high concentrations, never actually seen in real people. The bigger thing I watch with Giloy is that it's been linked to rare liver injury, and acetaminophen is hard on the liver too. Please check with your pharmacist or doctor before combining them.
