how much cetirizine is lethal dose

Cetirizine is an antihistamine commonly used to treat allergies. The exact lethal dose can vary depending on individual factors such as age, weight, health status, and sensitivity to the medication. While there is no established "lethal dose" for cetirizine specifically in humans, it is generally considered to have a high safety margin. Overdosing on cetirizine can lead to serious side effects, including extreme drowsiness, confusion, or rapid heart rate, but fatal outcomes are rare. The recommended doses for adults are usually 10 mg once daily, and doses above this may increase the risk of adverse effects. If there is any concern about an overdose or adverse reaction, it is crucial to seek medical attention immediately. Do not rely on self-diagnosing or self-treating; contacting a healthcare provider is essential for safety.
