Gamma-hydroxybutyrate (ghb) and Aripiprazole

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

Major

CNS DEPRESSANTS

Why this applies to Aripiprazole

Aripiprazole falls under CNS DEPRESSANTS — the group Gamma-hydroxybutyrate (ghb) interacts with.

GHB may increase the risk of serious CNS and respiratory depression.
Concomitant use of GHB with CNS depressants may increase the risk of serious CNS and respiratory depression.
Severity Major Likelihood Probable Evidence D

Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports..

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

Here's the simple version: both of these slow down your brain and nervous system. GHB is a strong central nervous system depressant, and aripiprazole (Abilify) can also cause sleepiness and a calming effect for many people. Stack them together and those effects can pile up, leaving you very drowsy, dizzy, slow to react, or in serious cases struggling to breathe.

This isn't about one drug changing how the other is broken down. It's the two sedating effects adding up. The supporting evidence here is mostly anecdotal, but because GHB itself is so dangerous (it can cause coma and breathing failure even alone), I'd treat this combination as a real concern. Please don't change anything on your own, just loop in your doctor or pharmacist first.

About Gamma-hydroxybutyrate (ghb)

What is Gamma-hydroxybutyrate (ghb)?

  • Narcolepsy (cataplexy and excessive daytime sleepiness)
  • Sleep aid
  • Misused as a recreational 'party drug'
  • Bodybuilding/muscle building (unproven)
  • Alcohol withdrawal (in some countries)

GHB (gamma-hydroxybutyrate) is a powerful central nervous system depressant that is NOT a safe dietary supplement. In the U.S. it is a controlled substance, and only a tightly regulated prescription form (sodium oxybate) is legal for narcolepsy. Non-prescription GHB can cause coma, breathing failure, and death, and it is also a known 'date-rape' drug — it should not be taken outside of medical supervision.
