I worked as a medication aide for several years and I was told that MOST OTC meds can be taken 3 times more or stronger than what is actually on the dosing instructions. Is this really true? What is the amount of Zyrtec that would be considered an overdose?
Where did you hear that most of the OTC meds can be taken 3 times more or stronger? What would happen if Tylenol (acetaminophen) is taken 3 times or stronger?
Cetirizine Dosage for Adults and Older Children
The recommended dose of cetirizine for most adults and children age six and over is cetirizine 10 mg once daily. For mild symptoms, cetirizine 5 mg once daily may be sufficient.
The label of cetirizine recommends that people age 65 and older check with their healthcare providers before taking the drug in order to determine the best dose. It is common for liver and kidney function to decline with age, and a lower cetirizine dosage may be recommended.
Cetirizine Dosage for Young Children
The recommended dose of cetirizine for children ages two through five is cetirizine 2.5 mg once daily. This dose is equivalent to half a teaspoonful (2.5 mL) of cetirizine syrup. Consult your child's healthcare provider if your child has liver or kidney problems, as a lower dosage may be recommended. Only the syrup form, designed to treat allergies, is approved and labeled for this age group. Other cetirizine products are not approved for this young age range.
The dosage recommended for citrizine, anything above the recommended dosage would be an overdose.
