Karbinal ER



Overdosage with carbinoxamine may cause central nervous system depression or stimulation, hallucinations, convulsions, and death. Atropinelike signs and symptoms – dry mouth; fixed, dilated pupils; flushing; and gastrointestinal symptoms may also occur.

The treatment of overdosage consists of discontinuation of Karbinal ER and institution of symptomatic and supportive therapy. Vital signs (including respiration, pulse, blood pressure, and temperature) and EKG should be monitored. Induction of vomiting is not recommended. Activated charcoal should be given and gastric lavage should be considered after ingestion of a potentially life-threatening amount of drug. In the presence of severe anticholinergic effects, physostigmine may be useful. Vasopressors may be used to treat hypotension.
