Vistaril may also be used for nausea and vomiting, or for allergic skin reactions such as hives breakout or contact dermatitis. It can be secondarily used short-term to treat anxiety and tension.

How to use it?

The medicine is to be administered by the doctor and strictly followed as directed by the doctor. In most cases, doctors recommend three to four doses of the medicine daily with or without food.

For the liquid form of Vistaril, invest in a measuring spoon to measure out the exact quantity of the medicine prescribed to prevent the risk of overdose or other such complications. Do not use a household spoon as it entails the risk of administering inaccurate amounts of the drug.

The dosage in adults is determined by certain factors such as the patient’s medical condition, age, and response to treatment. In children, the dosage may also be contingent upon their weight. Do not increase the dose or take it more often without consulting the doctor as this may have dire consequences.

As with all medications, the dosage should be adjusted according to the patient’s response to therapy gradually over the course of treatment.

Tell your doctor if your condition shows no improvement or starts to worsen
