Tarragon and Acetaminophen, Codeine

Here is the interaction we found between these two, with the evidence behind it.

Moderate

CNS DEPRESSANTS

Why this applies to Acetaminophen, Codeine

Acetaminophen, Codeine falls under CNS DEPRESSANTS — the group Tarragon interacts with.

Evidence from animal research suggests that tarragon essential oil can cause sedation and motor impairment when administered intraperitoneally at a dose of 1 mL/kg. Theoretically, concomitant use of tarragon with CNS depressants, including antihistamines, barbiturates, benzodiazepines, and tricyclic antidepressants, may increase sedative and other adverse 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: this combo with Tylenol with Codeine is about overlapping sleepiness, not about how your liver processes the drug. Codeine is an opioid that already makes a lot of people feel drowsy, foggy, or slowed down. Tarragon, at least in animal studies using concentrated essential oil, also caused sedation. Put the two together and the worry is simply that you could feel more tired, less steady on your feet, or more out of it than usual.

One important point: this is based on animal research, not solid human studies, and the sprinkle of tarragon in your cooking is very unlikely to do anything. Concentrated tarragon extracts or essential oil are the real question. If you're considering those while taking this medicine, check with your pharmacist or doctor first.

About Tarragon

What is Tarragon?

Tarragon
  • Digestive upset
  • Appetite stimulation
  • Sleep and mild restlessness
  • Toothache and oral discomfort
  • Blood sugar support (preliminary)
  • Culinary flavoring

Tarragon is a flavorful culinary herb that has been used in traditional medicine for digestion, sleep, and other complaints, but solid human evidence for any health benefit is lacking. Amounts used in cooking are generally considered safe, while concentrated extracts and the essential oil should be used cautiously because tarragon contains estragole, a compound studied for possible safety concerns. Talk to your pharmacist or doctor before using tarragon as a supplement.
