Licorice and Meloxicam

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

Moderate

CYTOCHROME P450 2C9 (CYP2C9) SUBSTRATES

Why this applies to Meloxicam

Meloxicam falls under CYTOCHROME P450 2C9 (CYP2C9) SUBSTRATES — the group Licorice interacts with.

Theoretically, licorice might increase or decrease levels of drugs metabolized by CYP2C9.
There is conflicting evidence about the effect of licorice on CYP2C9 enzyme activity. In vitro research shows that extracts from the licorice species G. glabra and G. uralensis moderately inhibit CYP2C9 isoenzymes. However, evidence from an animal model shows that licorice extract from the species G. uralensis can induce hepatic CYP2C9 activity. Until more is known, licorice should be used cautiously in people taking CYP2C9 substrates.
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 situation with licorice and your meloxicam. Your body relies on a liver enzyme called CYP2C9 to clear meloxicam out of your system. Licorice might nudge that enzyme one way or the other, but honestly the evidence is shaky. Lab studies suggest it could slow the enzyme down (which could let meloxicam build up, meaning more chance of stomach upset, ulcers, fluid retention, or higher blood pressure), while animal data hints it could speed it up (which could make meloxicam work less well).

Because the science points in both directions and is only based on lab and animal work, I wouldn't lose sleep over an occasional licorice tea. The bigger concern is that licorice itself can raise blood pressure, and so can meloxicam. If you take licorice supplements regularly, run it past your pharmacist or doctor first.

From our pharmacist’s overview on the Meloxicam page

“Most people take meloxicam (Mobic) daily for arthritis pain, which gives supplement interactions time to add up, so I read this list with real vigilance. Five of the 113 ingredients on file carry a major rating, and two are simply beer and wine, because alcohol plus any NSAID raises the odds of stomach bleeding.”

About Licorice

What is Licorice?

Licorice
  • Sore throat and cough
  • Heartburn and stomach upset
  • Mouth ulcers and digestive complaints
  • Inflammation
  • Traditional tonic/adrenal support

Licorice root is a traditional remedy used for sore throats, coughs, and digestive complaints, but solid human evidence is limited for most uses. Regular licorice contains glycyrrhizin, which can raise blood pressure and lower potassium when taken in large amounts or for a long time, so deglycyrrhizinated (DGL) products are often preferred. Talk to your pharmacist or doctor before using it, especially if you have high blood pressure, heart, or kidney problems.

About Meloxicam

What Is Meloxicam Used For?

Brand names: Mobic, Vivlodex, Qmiiz ODT, Anjeso

Meloxicam tablets and oral suspension treat the signs and symptoms of osteoarthritis, rheumatoid arthritis, and juvenile rheumatoid arthritis (JRA). The oral suspension and Zybic™ oral suspension are approved for JRA in children 2 years and older; meloxicam tablets are approved for JRA in patients who weigh at least 60 kg. Meloxicam capsules are approved specifically for the management of osteoarthritis pain.

Two IV (intravenous) formulations — QAMZOVA and XIFYRM — are indicated for adults for the management of moderate-to-severe pain, used alone or with non-NSAID pain relievers. Because these IV forms take time to reach full effect, they are not recommended when rapid pain relief is needed.
