General Description

 

Hydroxyzine is an antihistamine used in the treatment of allergic reactions, as with snake and insect bites, vaccine reactions, alopecia, and other causes of itchy, inflamed skin. It has anti-nausea, sedative, anti-inflammatory, anti-anxiety, and anesthetic properties.

 

How It Works

 

Antihistamines counteract histamine, which is a chemical released to cause inflammation and itchiness as part of an allergic reaction. Hydroxyzine works by blocking H-1 receptors, which occur on the small blood vessels and smooth muscles. When histamine attaches to these receptors, it causes these vessels to widen causing inflammation and itchiness and muscles around the airways to contract, which causes difficulty breathing.

 

Storage Information

 

Keep in a tightly sealed container at room temperature.

 

Missed Dose?

 

If you miss a dose, give the dose as soon as possible. If it is almost time for the next dose, skip the missed dose, and continue with the regular schedule. Do not give your pet two doses at once.
