False Unicorn and Aripiprazole Lauroxil

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

False Unicorn interacts with whole categories of medication. Aripiprazole Lauroxil falls into 2 of those categories, so it can interact with False Unicorn 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 Aripiprazole Lauroxil

Aripiprazole Lauroxil falls under CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES — the group False Unicorn interacts with.

In vitro, false unicorn extract inhibits cytochrome P450 2D6 (CYP2D6) activity. Theoretically, false unicorn might increase the levels of CYP2D6 substrates. Some of drugs that are CYP2D6 substrates include amitriptyline (Elavil), clozapine (Clozaril), codeine, desipramine (Norpramin), donepezil (Aricept), fentanyl (Duragesic), flecainide (Tambocor), fluoxetine (Prozac), meperidine (Demerol), methadone (Dolophine), metoprolol (Lopressor, Toprol XL), olanzapine (Zyprexa), ondansetron (Zofran), tramadol (Ultram), trazodone (Desyrel), and others.
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

Your body relies on a liver enzyme called CYP2D6 to help clear aripiprazole (the active drug inside Aristada). In a lab dish, False Unicorn appears to slow that enzyme down. The concern is that if this enzyme works less efficiently, more aripiprazole could linger in your system, which in theory could nudge up side effects like drowsiness, restlessness (feeling unable to sit still), dizziness, tremor, or low blood pressure.

Here's the reassuring part: this is based only on test-tube data, not on real people, so it's quite uncertain. Still, since Aristada is a long-acting injection you can't easily take back, I'd play it safe. Please run False Unicorn by your prescriber or pharmacist before combining the two.

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

2 of 2

Aripiprazole Lauroxil also falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES.

In vitro, false unicorn extract inhibits cytochrome P450 3A4 (CYP3A4) activity. Theoretically, false unicorn might increase the levels of CYP3A4 substrates. Drugs that might be affected include some calcium channel blockers (diltiazem, nicardipine, verapamil), chemotherapeutic agents (etoposide, paclitaxel, vinblastine, vincristine, vindesine), antifungals (ketoconazole, itraconazole), glucocorticoids, cisapride (Propulsid), alfentanil (Alfenta), fentanyl (Sublimaze), losartan (Cozaar), fluoxetine (Prozac), midazolam (Versed), omeprazole (Prilosec), ondansetron (Zofran), propranolol (Inderal), fexofenadine (Allegra), and numerous others.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the situation with this long-acting aripiprazole injection (Aristada). Your liver uses an enzyme called CYP3A4 to help clear aripiprazole from your body. In lab dish testing, False Unicorn appeared to slow that same enzyme down. If that holds true in people, the medication could clear a little more slowly and build up, which might mean stronger side effects like sleepiness, restlessness, dizziness, tremor, or low blood pressure when you stand up.

The honest part: this is based only on test-tube data, not on real patients, so it's theoretical and far from proven. Still, since this is a steady, long-acting shot you can't easily "undo," I'd play it safe. Please check with your pharmacist or prescriber before adding False Unicorn, and don't change your injection schedule on your own.

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.”
