Dandelion and Imipramine

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

Moderate

CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES

Why this applies to Imipramine

Imipramine falls under CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES — the group Dandelion interacts with.

Theoretically, dandelion might increase levels of drugs metabolized by CYP1A2.
Laboratory research suggests that dandelion might inhibit CYP1A2. So far, this interaction has not been reported in humans. However, until more is known, watch for an increase in the levels of drugs metabolized by CYP1A2 in patients taking dandelion.
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 imipramine and dandelion. Your liver uses an enzyme called CYP1A2 to help break down imipramine. Lab studies hint that dandelion might slow that enzyme down. If that happened in real life, imipramine could clear out a little slower and build up in your body, which can mean stronger side effects like drowsiness, dry mouth, constipation, blurry vision, dizziness when you stand, or a faster heartbeat.

The important part: this is only test-tube and animal data, and it has never actually been reported in people. Eating dandelion as a food is very unlikely to matter. Concentrated supplements are the bigger question mark, so it's worth a quick chat with your pharmacist or doctor before starting one.

From our pharmacist’s overview on the Imipramine page

“Imipramine (Tofranil) is an older tricyclic antidepressant, and the supplements on this page deserve real scrutiny before you add one. Most of the list acts on the liver enzymes that process the drug, so an ingredient can quietly raise or lower imipramine levels: grapefruit pushes them up, while St.”

About Dandelion

What is Dandelion?

Dandelion
  • Water retention (diuretic)
  • Digestive upset
  • Liver and gallbladder support
  • Mild appetite stimulant
  • Skin conditions

Dandelion is a common plant used in food and traditional medicine, often promoted as a natural 'water pill' and digestive aid. Human evidence for these uses is very limited, so its benefits are not well proven. It is generally considered safe as a food, but talk to your pharmacist or doctor before using concentrated supplements, especially if you have allergies or take other medicines.

About Imipramine

What Is Imipramine Used For?

Brand names: Tofranil, Tofranil PM

Imipramine is used to relieve symptoms of depression. Both Imipramine Hydrochloride tablets and Imipramine Pamoate capsules are approved for this use. Endogenous depression — the kind that seems to arise from within rather than a clear outside cause — tends to respond especially well. It may take one to three weeks before you notice the full benefit.

Imipramine Hydrochloride tablets are also approved as a short-term, add-on treatment to help reduce nighttime bedwetting (nocturnal enuresis) in children aged 6 and older, after a doctor has ruled out physical causes.
