Red Clover and Aripiprazole Lauroxil

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

Minor

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Aripiprazole Lauroxil

Aripiprazole Lauroxil falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Red Clover interacts with.

Theoretically, red clover might increase levels of drugs metabolized by CYP3A4; however, a small clinical study found no effect.
In vitro evidence shows that red clover might inhibit CYP3A4 isoenzymes. However, a clinical study in healthy postmenopausal individuals shows that taking red clover capsules standardized to contain 60 mg isoflavones twice daily for 14 days does not affect the pharmacokinetics of alprazolam, a CYP3A4 probe substrate.
Severity Minor Likelihood Unlikely Evidence B

Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans..

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the short version: this is a very minor, mostly theoretical concern. Aristada (aripiprazole lauroxil) is a long-acting injection that your body partly clears through a liver enzyme called CYP3A4. In a test tube, red clover looked like it might slow that enzyme down, which in theory could let aripiprazole levels creep up and bring on more side effects like drowsiness, restlessness, dizziness, or mild tremor.

But here's the reassuring part: when researchers actually tested red clover in people, it did not meaningfully change the levels of a similar CYP3A4 drug. So real-world impact appears unlikely. Since your injection is dosed carefully by your provider, it's still worth mentioning red clover to your pharmacist or doctor before starting it, just so everyone's on the same page.

From our pharmacist’s overview on the Aripiprazole Lauroxil page

“Aripiprazole lauroxil (Aristada) is a long-acting antipsychotic injection, and because each dose keeps working for weeks, a bad supplement pairing cannot be undone by skipping a pill. So the 16 major-rated entries among its 233 interactions on file deserve to be understood first.”

About Red Clover

What is Red Clover?

Red Clover
  • Menopause symptoms (hot flashes)
  • High cholesterol
  • Bone health/osteoporosis
  • Skin and hair concerns
  • Women's health

Red clover is a plant rich in isoflavones (plant compounds with weak estrogen-like activity) that is most often used for menopause symptoms like hot flashes. The evidence is mixed and generally weak, with some studies showing modest benefit and others showing none. Because of its hormone-like effects, it's not for everyone—talk with your pharmacist or doctor before trying it, especially if you have a hormone-sensitive condition.
