Cetirizine is an antihistamine commonly used to relieve allergy symptoms such as sneezing, runny nose, and itching. It is generally considered safe when taken as directed, with the recommended dose being one tablet per day in most cases.
However, taking a significantly higher dose than prescribed can lead to an overdose, which may cause serious health issues. Symptoms of an overdose can include restlessness, drowsiness, rapid heartbeat, and confusion. In extreme cases, it could lead to seizures, coma, or even death.
The specific amount of cetirizine that can be lethal varies depending on factors such as a person's weight, age, and overall health. Taking ten tablets of cetirizine at once is a considerable overdose and can be extremely dangerous.
If you suspect someone has taken an overdose of cetirizine or any medication, it's vital to seek immediate medical attention by calling emergency services or contacting a poison control center. Always take medications as prescribed and never exceed the recommended dosage without consulting a healthcare professional.
