Interaction report

Black Seed and Aripiprazole Lauroxil

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

Why Are There 2 Interactions?

Black Seed interacts with whole categories of medication. Aripiprazole Lauroxil falls into 2 of those categories, so it can interact with Black Seed in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

CNS DEPRESSANTS

1 of 2

Why this applies to Aripiprazole Lauroxil

Aripiprazole Lauroxil falls under CNS DEPRESSANTS — the group Black Seed interacts with.

Theoretically, concomitant use with drugs that have sedative properties may cause additive effects.
Animal research suggests that black seed may have CNS depressant 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 explains PharmD, Clinical Pharmacist

Here's the simple version. Aripiprazole lauroxil (Aristada) is a long-acting injection that can already make some people feel drowsy or slowed down. Black seed, in animal studies, seems to have its own mild calming or sedative effect. So the concern is that putting the two together might add up, leaving you more sleepy, foggy, dizzy, or unsteady than usual.

I want to be honest about the strength of this: it's theoretical, based on lab and animal research, not on people. A pinch of black seed as a cooking spice is very unlikely to cause trouble. Concentrated supplement doses are the bigger unknown. If you'd like to try a black seed supplement, just run it by your pharmacist or prescriber first, and watch for extra daytime drowsiness.

SEROTONERGIC DRUGS

2 of 2

Aripiprazole Lauroxil also falls under SEROTONERGIC DRUGS.

Theoretically, combining serotonergic drugs with black seed might increase the risk of serotonergic side effects, including serotonin syndrome and cerebral vasoconstrictive disorders.
Animal research suggests that black seed can increase brain serotonin levels. In one case report, a 35-year-old man undergoing endoscopic surgery experienced immediate postoperative serotonin syndrome that was likely associated with the use of black seed oil 600 mg daily starting 4 days before surgery, and precipitated by the use of serotonergic pain medications, including fentanyl and oxycodone. Monitor patients for signs of serotonin syndrome and other serotonergic side effects if using black seed with serotonergic drugs.
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 gist: black seed may nudge serotonin levels up in the brain, at least based on animal work and one single case report. Aripiprazole lauroxil (Aristada) isn't a classic serotonin drug like an antidepressant, but it does touch serotonin receptors, so it gets grouped with serotonergic medicines. In theory, pairing the two could add to serotonin-related effects.

What that might look like in real life is feeling restless or agitated, shaky, sweaty, having a racing heart, or muscle twitching. Honestly, this is a theoretical concern built on weak evidence, and food-amount black seed (as a spice) is very unlikely to cause trouble. Concentrated oil capsules are the bigger question mark. Before adding a black seed supplement, just run it by your pharmacist or prescriber.

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.”

Black seed (Nigella sativa) is a traditional spice and remedy that has been studied for asthma, blood sugar, cholesterol, and blood pressure, with early research showing some promise but no firmly proven benefits. It is generally well tolerated in food amounts, but supplement-strength doses are less studied, so talk to your pharmacist or doctor before using it—especially if you are pregnant, breastfeeding, or take other medicines.
