Overdosage
In clinical pharmacology trials, buspirone up to 400 mg/day was administered to healthy male volunteers. As this dose was approached, the following symptoms were observed in descending order of freque
ncy: drowsiness, ataxia, nausea and vomiting, dizziness, clammy feeling, difficulty thinking, feeling high, rushing sensation, gastric distress, headache, itching, miosis, hypotension, tremor, incoord
ination, insomnia and hallucinations. In a dose ranging study in acute psychotic patients, up to 2400 mg/day was administered. Dizziness, nausea and vomiting were the most common adverse effects. One
patient developed extrapyramidal symptoms at 600 mg/day.

Food increased the bioavailability of unchanged buspirone in healthy subjects, possibly due to a reduced first-pass effect.
