Methylene Blue and Aripiprazole

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

Moderate

Serotonergic Drugs

Why this applies to Aripiprazole

Aripiprazole falls under Serotonergic Drugs — the group Methylene Blue interacts with.

Combining serotonergic drugs with methylene blue can cause additive serotonergic effects, including serotonin syndrome. Methylene blue inhibits monoamine oxidase A. Intravenous or intrapulmonary use has resulted in serotonin syndrome, including reported fatalities, in patients taking some serotonergic drugs. This effect has not been reported with oral methylene blue. However, tell patients to avoid taking methylene blue with serotonergic drugs.
Severity Moderate Likelihood Possible Evidence C

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 concern when methylene blue meets aripiprazole (Abilify). Methylene blue acts like a strong MAO inhibitor, meaning it blocks an enzyme that normally clears serotonin from your brain. Aripiprazole nudges serotonin activity too, so stacking the two can let serotonin climb higher than it should. That can lead to serotonin syndrome, which shows up as agitation, a racing heart, sweating, shivering, muscle twitching or stiffness, and in serious cases high fever and confusion.

The good news: the scary, sometimes fatal cases were tied to injectable methylene blue given in hospitals, not everyday oral supplement doses. Still, this pairing isn't worth the gamble. Please talk with your pharmacist or doctor before combining them, and don't start or stop anything on your own.

About Methylene Blue

What is Methylene Blue?

Methylene Blue
  • Methemoglobinemia (a blood disorder)
  • Claimed energy or mental focus support
  • Anti-aging or longevity claims
  • Antimicrobial or antimalarial uses (historical)
  • Dye for medical and lab procedures

Methylene blue is a synthetic dye that is an FDA-approved prescription medicine for a rare blood disorder called methemoglobinemia, and it is also used as a diagnostic dye. Its popular use as a supplement for energy, brain health, or anti-aging is not well supported by solid human evidence, and it can cause serious side effects. Talk to a pharmacist or doctor before using it, and never take non-pharmaceutical or industrial-grade products.
