Drug Information for Strattera (Physicians Total Care, Inc.): 10 OVERDOSAGE

No fatal overdoses occurred in clinical trials. There is limited clinical trial experience with STRATTERA overdose. During postmarketing, there have been fatalities reported involving a mixed ingestion overdose of STRATTERA and at least one other drug. There have been no reports of death involving overdose of STRATTERA alone, including intentional overdoses at amounts up to 1400 mg. In some cases of overdose involving STRATTERA, seizures have been reported. The most commonly reported symptoms accompanying acute and chronic overdoses of STRATTERA were somnolence, agitation, hyperactivity, abnormal behavior, and gastrointestinal symptoms. Signs and symptoms consistent with mild to moderate sympathetic nervous system activation (e.g., mydriasis, tachycardia, dry mouth) have also been observed. Less commonly, there have been reports of QT prolongation and mental changes, including disorientation and hallucinations.

An airway should be established. Monitoring of cardiac and vital signs is recommended, along with appropriate symptomatic and supportive measures. Gastric lavage may be indicated if performed soon after ingestion. Activated charcoal may be useful in limiting absorption. Because atomoxetine is highly protein–bound, dialysis is not likely to be useful in the treatment of overdose.
