Hydroxyzine is a commonly prescribed medication used to treat anxiety and insomnia. Understanding the maximum safe dose is crucial for its effective and safe use. This article provides a comprehensive overview of hydroxyzine, including its maximum daily dosage, potential side effects, and the importance of consulting a healthcare professional.

Understanding Hydroxyzine

Hydroxyzine is an antihistamine with anxiolytic and sedative properties. It's available in different formulations, including tablets, capsules, and syrup. The specific dosage and formulation will depend on your individual needs and your doctor's prescription. Never attempt to adjust your medication without first consulting your doctor.

Forms of Hydroxyzine

Hydroxyzine comes in several forms, impacting how quickly it's absorbed and its duration of effect.

Hydroxyzine pamoate: This extended-release form provides a longer-lasting effect.
Hydroxyzine hydrochloride: This immediate-release form works more quickly but doesn't last as long.

What is the Maximum Daily Dose of Hydroxyzine?

The maximum recommended daily dose of hydroxyzine varies depending on the specific formulation and the individual's needs. It's crucial to follow your doctor's prescribed dosage and never exceed it without medical supervision. Generally, the maximum daily dose ranges from:

Hydroxyzine pamoate: The maximum daily dose is usually 600mg for adults. This is typically divided into several doses throughout the day.
Hydroxyzine hydrochloride: The maximum daily dose is usually 300mg for adults. Again, this is often divided into smaller doses.

Important Note: These are general guidelines. Your doctor will determine the appropriate dosage based on your medical history, condition, and response to the medication. Always follow your doctor's instructions precisely.
