General Description
Acepromazine is the most common tranquilizer and central nervous system depressant given to pets. It is used to prevent anxiety associated with thunder, fireworks, vet or groomer visits, and other things your pet may fear. It is effective treatment against motion sickness and nausea associated with car or plane rides.
The effects typically last 6-8 hours. It is more effective to give this drug 45-60 minutes before your pet is expected to display any anxious behavior.
How It Works
How Acepromazine works is not well known. It is, however, suspected that it acts on the receptors in the brain for dopamine. Dopamine transmits emotion signals from cell to cell and by blocking these receptors, prevents pets from exhibiting extreme fear or anxiety.
Acepromazine also stabilizes the heart rhythm, lowers blood pressure, and acts on the brain to reduce your pet’s nausea.
Storage Information
Store in a tightly sealed container at room temperature.
Missed Dose?
