Arsenic and Aripiprazole

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

Major

QT INTERVAL-PROLONGING DRUGS

Why this applies to Aripiprazole

Aripiprazole falls under QT INTERVAL-PROLONGING DRUGS — the group Arsenic interacts with.

Arsenic trioxide can prolong the QT interval.
Up to 40% of patients treated with prescription arsenic trioxide have a prolonged QT interval on their electrocardiogram (ECG). Theoretically, non-prescription arsenic could have an additive effect when combined with drugs that prolong the QT interval.
Severity Major Likelihood Probable Evidence B

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 concern with arsenic and aripiprazole (Abilify). Arsenic, especially the prescription form arsenic trioxide, can stretch out a part of your heart's rhythm called the QT interval. Aripiprazole can also nudge that same interval, though it's considered a fairly low risk on its own. The worry is that putting the two together could add up and raise the chance of a dangerous heart rhythm problem.

To be clear, this is mostly a theoretical stacking effect, and it's based on what we see with the prescription cancer drug, not from people taking random arsenic products. Still, you shouldn't be taking arsenic supplements at all, since they're toxic. If you've been exposed to arsenic or are worried, please talk with your pharmacist or doctor rather than changing your aripiprazole.

About Arsenic

What is Arsenic?

Arsenic
  • Homeopathic digestive complaints
  • Traditional remedy for inflammatory conditions
  • Prescription use in certain leukemias (medical, not supplement)
  • Anxiety and restlessness (homeopathic tradition)

Arsenic is a naturally occurring element that is toxic in its inorganic form, and it is not a supplement you should take to improve your health. While arsenic trioxide is a real, doctor-prescribed cancer medicine, and tiny homeopathic doses exist, there is no good reason to take arsenic on your own. Avoid arsenic-containing products and talk to a pharmacist or doctor about any concerns.
