Alprazolam (Xanax) is a benzodiazepine used to treat anxiety in cats and dogs. It helps them manage fear and stress from things like loud noises, vet visits, or travel. This medication is given by mouth — usually as a tablet or liquid — either daily or as needed. Veterinarians prescribe it off-label for pets, which means it's FDA-approved for humans but can still be used in animals with a vet’s guidance. The most common side effect is sleepiness or sedation.
Alprazolam is a benzodiazepine. It works by boosting the effect of a natural calming chemical in the brain, helping to reduce feelings of fear, stress, and anxiety.
Alprazolam can cause some serious health issues. This risk might be even higher for certain pets. If this worries you, talk to your veterinarian about other options.
Giving your pet alprazolam with other medications that cause slow breathing, like opioids, can lead to dangerous breathing problems. The risk is higher if your pet has lung problems or is taking a high dose. If you notice your pet is breathing slowly or having trouble breathing, call your veterinarian or a pet poison helpline right away.
Don’t give your pet more alprazolam than your veterinarian has prescribed. Taking too much medication can cause an overdose, which could be life-threatening. Signs of overdose include slowed breathing, trouble walking, balance problems, weakness, confusion, or vomiting. If you think your pet has had too much, contact a veterinarian or pet poison helpline right away.
Pets that take alprazolam for a long time can develop dependence, meaning their body gets used to the medication. If it’s stopped too suddenly, they might go through withdrawal. Always talk to your veterinarian before changing the dose or stopping the medication. They might recommend slowly lowering the dose over time to keep your pet safe.
Alprazolam can cause some pets to lose self-control. Even pets that have never been aggressive before might act aggressive while taking this medication. Watch your pet closely around children and other animals to help prevent injuries. Let your veterinarian know right away if your pet shows any signs of aggression like growling, snarling, or biting.
Another medication in the benzodiazepine class, diazepam, has rarely caused liver problems in cats. This hasn’t been reported with alprazolam, but it could still happen. Watch for signs of liver problems like yellowing of the eyes or gums, loss of appetite, or extreme tiredness, and contact your veterinarian if you notice anything unusual.
The following side effects might get better over time as your pet gets used to the medication. Let your veterinarian know immediately if your pet continues to experience these symptoms or if they worsen over time.
Contact your veterinarian immediately if your pet experiences any of the following.
