Same and Ziprasidone

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

Moderate

SEROTONERGIC DRUGS

Why this applies to Ziprasidone

Ziprasidone falls under SEROTONERGIC DRUGS — the group Same interacts with.

Taking SAMe with serotonergic drugs might increase the risk of serotonin syndrome and other serotonergic side effects.
SAMe has serotonergic effects. Theoretically, combining serotonergic drugs with SAMe might increase the risk of serotonergic side effects, including serotonin syndrome and cerebral vasoconstrictive disorders. In one case report, SAMe 100 mg intramuscularly was given daily with clomipramine (Anafranil) 25 mg per day. When the clomipramine dose was increased to 75 mg per day the patient experienced serotonin syndrome about 48-72 hours later, requiring hospitalization.
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 thing to know if you're taking ziprasidone (Geodon) and thinking about SAM-e. SAM-e has its own mild serotonin-boosting activity, and ziprasidone also nudges serotonin signaling in the brain. Stacking the two could, in theory, push serotonin levels a little too high. That's what we call serotonin syndrome, and signs include feeling agitated or restless, a racing heart, sweating, shivering, muscle twitching, or confusion.

I want to be honest about the evidence: this concern is mostly theoretical and comes from a single case report with a different medicine, so it's far from a sure thing. Still, since both of these affect mood chemistry and you may already be managing depression or bipolar disorder, please loop in your pharmacist or doctor before adding SAM-e rather than starting it on your own.

From our pharmacist’s overview on the Ziprasidone page

“Ziprasidone (Geodon) is an antipsychotic that already carries a warning about disturbing the heart's electrical rhythm, so a list with 11 major-rated interactions calls for real care before mixing in supplements. Most of the 188 ingredients on file touch the liver enzyme, CYP3A4, that clears ziprasidone from the body.”
