Dog vomiting & diarrhea after Trazodone for fireworks. Is it serious?

I am afraid, this could indeed be a side effect of Trazodone. The manufacturer lists the following possible side effectsÆ Trazodone Side Effects in Dogs Lethargy, Sedation, Diarrhea, Vomiting, Panting, Hyperactivity, Shaking, Restlessness. I suggest you contact your vet and ask about dosage adjustment.

Hi there. I would be concerned with Hershey developing serotonin syndrome with concurrent use of trazadone and fluoxetine especially if you are giving them together often. It has to do with how the drugs are metabolized in the body and what receptors they work on. Side effects can be as you have listed, as with diarrhea, labored fast breathing, etc. I would try calling your doctor to discuss changing the dosages or weaning off the trazadone altogether. Hope this helps!

Yes you can give it with the other medications. Personally I’d not give Nico the gabapentin when giving the trazodone just to be extra cautious since you’ll only be giving it one night for the fireworks.

While it's possible that this was related to the trazodone causing sedation, this is a relatively low dose for a dog her size and I would think you would have seen signs sooner. It is possible that she had some hip pain. Other causes of uncoordinated movement would include a neurologic problem like a seizure, or certain toxins. If she seems to be her normal self again I think it would be safe to try another dose of trazodone during the day when you can monitor closely (check with your vet first). If she is still not walking normally or seems painful I'd recommend having her examined by your vet.

There is no problem with combining isoxazoline medication like Credelio with trazodone. It should be fine to give the trazodone as prescribed. Potential side effects of both medication include diarrhea and a decrease in appetite, but if you have given both medications before without a problem you’re unlikely to see this problem now.

Serotonin syndrome is certainly possible with fluoxetine and trazodone together, or even just fluoxetine by itself, but what you're seeing with Luna does not sound like serotonin syndrome. With serotonin syndrome there's just too much of everything, too much energy, too much vomiting, too much diarrhea, too much muscle movement (tremors and seizures), too much pupil size. Sedation is an expected and desirable side effect of Trazodone, so in this situation I wouldn't worry. I would recommend giving a slightly smaller dose of trazodone tomorrow to see if that is enough to keep Luna calm. And always, if you're worrying about it and not sure, take Luna to an emergency clinic for an quick check in. Also, these two drugs are used together VERY commonly in veterinary medicine, but I don't think human doctors use them together, so you'll see lots of precautions against it while reading online. I hope that helps you feel better! Thanks for using Petco Pet Education Center, formerly Petcoach.

Hello and thank you for contacting Petco Pet Education Center, formerly Petcoach. Some dogs poop only once a day and it is considered perfectly normal. As long as Romeo is eating well, not vomiting and his energy level is high, there is nothing to worry about. Trazadone can produce gastrointestinal symptoms like vomiting, diarrhea, increased appetite but it is not known to cause less frequent defecation or constipation in dogs.
