"Symptoms and Treatment: Overdose has not been reported with cetirizine in North America. In foreign marketing experience, somnolence has been reported in cases of overdose up to 150 mg. If an acute overdose occurs, evacuation of the stomach should be considered during the first few hours after this overdose. Treatment should be symptomatic and supportive taking into account any concomitantly ingested medications. There is no known specific antidote to cetirizine. Cetirizine is not effectively removed by dialysis, and dialysis will be ineffective unless a dialyzable agent has been concomitantly ingested. The minimal lethal oral dose in rodents is at least 590 times the maximum clinically studied dose."
FOREIGN MARKETING EXPERIENCE?
What the f**k.
I have to stop thinking about this now or I'm going to cry.
