The sedative drug phenobarbital can lower a patient's blood pressure.

the verdict
INSUFFICIENT LEANING
Recorded sources
2 sources for · 0 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that the sedative drug phenobarbital can lower a patient's blood pressure?

Unclear. A 2026 meta-analysis of neonatal seizure trials reports that phenobarbital was associated with higher risk of hypotension than levetiracetam, and two nursing pharmacology textbook snippets associate phenobarbital with monitoring a patient's blood pressure, though those snippets are truncated. Together these partially support, but do not fully establish, that phenobarbital can lower a patient's blood pressure.
