trazodone
Trazodone is an atypical antidepressant that’s FDA approved to treat depression in people. Your vet might prescribe this medication off-label for your cat or dog to ease separation anxiety or anxiety related to certain situations, like a vet visit, fireworks, or travel. Trazodone is commercially available as tablets, but it can be compounded into a liquid. Both forms of the medication are given to your pet to take by mouth. Trazodone is typically given 1 to 3 hours before the stressful event, or as directed by the vet. Side effects that your pet could have include sleepiness, vomiting, diarrhea, and gagging.

Pros and cons of Trazodone for pets
Pros
- Works within 1 to 2 hours
- Tablets can be broken along the score line if needed
- Can give to your pet as needed
Cons
- Not typically a first-choice medication for anxiety
- Can't give to pets taking monoamine oxidase inhibitors (MAOIs) like selegiline (Anipryl)

Pharmacist tips for Trazodone for pets
- Trazodone is commercially available as 50 mg, 100 mg, 150 mg, and 300 mg tablets. Depending on your pet's dose, you might need to break the tablet at the score line.
- Let your vet know if your pet has trouble swallowing trazodone tablets. The vet might have the medication compounded into a liquid so it’s easier for your pet to take. If so, follow the vet or pharmacist’s directions about how to measure the liquid and store the medication. They’ll also talk to you about when the liquid expires.
- Trazodone might upset your pet’s stomach. If your pet vomits or drools after they take the medication, try giving it to them with food next time. Talk to your vet about whether you should give your pet the medication again if they vomit right after taking it.
- If you’re giving your pet trazodone to prevent anxiety for situations like vet visits or fireworks, try to give the medication 1 to 2 hours before the event. This is about the time for the medication to work its best. Keep in mind that giving trazodone with food might make it take longer to work.
- If your pet is a working or service animal, they might not be able to do their job after they take trazodone. This is because the medication can make them sleepy. Tell your vet about any service activities that your pet needs to do before they take this medication.
- If your pet needs to take trazodone every day for anxiety, don’t suddenly stop giving it to them without first talking with your vet. Otherwise, your pet might have withdrawal symptoms. If your pet needs to stop taking the medication, the vet might give you instructions to slowly lower the dose over time before completely stopping to prevent withdrawal.
- In addition to giving your pet trazodone, you can help calm their anxiety with behavior modification. Talk to your vet about techniques that you can add to your pet’s routine to help. For example, you can try changing your routine when you leave the house to help with separation anxiety. You can also try keeping your pet entertained with music or puzzles while you’re gone.
- Your vet might prescribe trazodone with other sedating medications, like gabapentin. Giving these medications together can make their sedating effects more intense. Your pet might need lower doses of these medications when they’re used together to keep your pet safe.
Common questions about Trazodone for pets
If your veterinarian prescribes trazodone for your dog, it could be the same trazodone that’s usually given to people. Currently, there are no commercially available forms of trazodone that are specifically FDA approved for dogs. So this means that trazodone typically for people gets prescribed off-label for your dog. But never give this medication to a dog unless directed by the veterinarian because the dose for dogs and people aren’t the same.
Trazodone is generally safe for most dogs if it’s taken as prescribed by a vet. It’s a good idea to check with your vet to make sure. This medication can cause some mild side effects, like sleepiness or nausea. But call your vet if your dog has more serious side effects, like agitation or vomiting, so they can talk with you about the next steps. Also, tell your vet about other medications that your dog is taking so they can check for possibly dangerous interactions. Certain medications, like selective serotonin reuptake inhibitors (SSRIs), monoamine oxidase inhibitors (MAOIs), and flea collars containing amitraz, can raise the risk for serotonin syndrome if they’re taken with trazodone. This is a rare but serious side effect that can lead to seizures and coma. Ask your vet if you have specific safety concerns about trazodone for your dog.
Dogs might start to feel calmer about an hour after they take trazodone before a stressful situation, like a vet visit or fireworks. If your dog is taking trazodone long term to treat behavior problems like separation anxiety, it might take several weeks before you see a more noticeable change in their behavior. Talk with your vet if you have more questions about what to expect after your dog takes trazodone.
Talk with your veterinarian about whether trazodone is safe for your cat. Most cats can take the medication without any serious problems. Some cats might get sleepy and others might have nausea or diarrhea after they take it. These side effects are usually mild. But if they become severe, let your vet know. Also, tell your vet about all the medications that your cat takes because trazodone can have serious drug interactions. For example, giving it together with selective serotonin reuptake inhibitors (SSRIs) like fluoxetine can raise the risk for your cat to have a rare but deadly reaction called serotonin syndrome. Speak with your vet if you have more safety concerns about trazodone for cats.
Trazodone and gabapentin are both medications FDA approved for people that veterinarians sometimes prescribe off-label to treat anxiety in dogs. But these two medications work in different ways. Trazodone eases anxiety by changing the levels of serotonin in the brain. Gabapentin works by changing the way nerve cells in the brain send out signals related to anxiety. Sometimes, vets might prescribe both medications at the same time if either medication alone isn’t enough to ease anxious behavior.
Yes, you can give trazodone and gabapentin to your cat if they’re prescribed by the veterinarian. Both medications can help ease anxiety in cats. Keep in mind that giving your cat both medications at the same time will make them more likely to have side effects like sleepiness. Let your vet know if your cat gets too sleepy or has other worrisome side effects. Your vet can talk to you about other options to manage your cat’s anxiety.
Trazodone can make your dog sleepy, which might also help calm them. How long this effect lasts can differ based on certain things, like your dog’s size and dosage. A study showed that the medication had a calming effect on some dogs for at least 4 hours. Keep in mind that your dog might look drowsy or sleepy. But depending on the dose, they might not be asleep the entire time. Talk with your vet if you have more questions on how trazodone might affect your dog.
Let your vet know if your cat or dog is pregnant and they’re prescribed to take trazodone. More research is needed to understand whether this medication is safe for pregnant cats and dogs. Your vet can talk with you about the risks and benefits of giving this medication to your pet.

Risks and warnings for Trazodone for pets
Trazodone 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.
Serotonin syndrome
- Risk factors: Taking other medications that raise serotonin levels
Pets that take trazodone can be at risk of developing a rare, but life-threatening condition called serotonin syndrome. Your pet is more likely to experience this side effect if they accidentally take more trazodone than prescribed (e.g., accidentally eating the medication bottle). In addition, your pet is at higher risk if they’re also taking other medications that raise serotonin levels, like selective serotonin reuptake inhibitors (SSRIs) or tricyclic antidepressants (TCAs).
Symptoms of serotonin syndrome include changes in behavior, diarrhea, shaking, high body temperature (fever), and even seizures. Contact your vet or an emergency vet as soon as possible if you notice that your pet is showing signs of serotonin syndrome.

Dogs
- Situational anxiety (e.g., before a vet visit): The typical dose ranges between 5 mg/kg to 7 mg/kg by mouth, given at least 90 minutes before the stressful situation. The maximum recommended total daily dose is 19.5 mg/kg.
- Separation anxiety: The typical starting dose ranges between 3 mg/kg to 7 mg/kg by mouth every 24 hours. The maximum daily dose is usually 19.5 mg/kg by mouth within 24 hours.
