Before prescribing a dosage of Vistaril, your healthcare provider will consider several factors, such as the medical condition being treated, your age and weight, other medications you are taking, and other medical conditions you may have. Vistaril comes in the form of capsules, suspension (oral liquid), and injections (administered into a muscle). It is usually taken two to four times daily.
The dose of Vistaril® (hydroxyzine) your healthcare provider recommends will vary, depending on a number of factors, including:
- The medical condition being treated
- Your age and weight (for children)
- Other medications you are taking
- Other medical conditions you may have.
As is always the case, do not adjust your dosage unless your healthcare provider specifically instructs you to do so.
The standard recommended dosing of oral Vistaril for treating anxiety in adults is 50 mg to 100 mg four times daily. For children over six years old, the oral dosage is 50 mg to 100 mg daily in "divided" doses (presumably two to four doses per day). For children under six years old, the oral dosage is 50 mg daily in divided dosings.
The recommended Vistaril injectable dose for anxiety or alcoholism in adults is 50 mg to 100 mg injected intramuscularly right away, followed by 50 mg to 100 mg ever four to six hours as needed. The patient can be switched to the oral form when appropriate.
The recommended injectable Vistaril dosing for treating nausea and vomiting in adults is 25 mg to 100 mg injected intramuscularly. For children, the dosage is calculated based on weight (0.5 mg per pound of body weight), injected intramuscularly.
