The maximum recommended dose of hydroxyzine can vary based on the specific condition being treated and the patient's individual characteristics. For adults, typical doses for anxiety range from 25 mg to 100 mg, taken up to four times daily [1]. However, doses may be increased to 200 mg per day in severe cases, with some sources indicating a maximum of 600 mg per day for hospitalized patients under close medical supervision [2]. For itching or hives, doses for adults are often 25 mg, taken three to four times daily, with a maximum of 100 mg in a single dose or 400 mg per day [1].
What are the risks of taking too much hydroxyzine?
Exceeding recommended doses of hydroxyzine can lead to an overdose, which may manifest as severe drowsiness, dizziness, confusion, nausea, vomiting, tremors, or irregular heartbeat [3]. In cases of extreme overdose, seizures or coma can occur [2]. It is crucial to adhere to prescribed dosages and consult a healthcare professional if symptoms worsen or if there are concerns about the amount of medication being taken.
How does hydroxyzine dosage differ for children?
Dosage for children is calculated based on their weight and age. For anxiety in children aged six years and older, the typical dose is 50 mg per day, divided into multiple doses [1]. For itching or hives, doses for children aged six years and older are generally 50 mg per day, divided into multiple doses [1]. For children under six years old, the maximum recommended dose is 50 mg per day, divided into multiple doses [1]. It is essential to consult a pediatrician for appropriate pediatric dosing.
What should I do if I miss a dose of hydroxyzine?
If a dose of hydroxyzine is missed, it should be taken as soon as remembered. However, if it is close to the time of the next scheduled dose, the missed dose should be skipped, and the regular dosing schedule should be resumed [4]. It is important not to double up on doses to compensate for a missed one.
Are there any interactions to be aware of with hydroxyzine?
Hydroxyzine can interact with other central nervous system depressants, such as alcohol, sedatives, and tranquilizers, potentially intensifying drowsiness and sedation [1]. It may also interact with certain heart medications [3]. Always inform your healthcare provider about all medications, including over-the-counter drugs and herbal supplements, that you are taking.
