New program tracks rare side effects of schizophrenia injection
NCT ID NCT01088386
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This program monitors 4000 people with schizophrenia who receive Zyprexa Relprevv, a long-acting injection. The goal is to track and reduce the risk of a rare but serious reaction called post-injection delirium/sedation syndrome (PDSS). Researchers will record how often PDSS happens and look for possible risk factors.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- olanzapine pamoate (Zyprexa Relprevv)
- What this could lead to
- If successful, this program could help make Zyprexa Relprevv safer by identifying risk factors and reducing rare but serious post-injection reactions.
- What could go wrong
- This is an observational safety program, not a test of whether the drug works. It may not change how the drug is used, and rare events may still occur.
