My 6-month-old kitten ate Cymbalta. Is it harmful to my cat? What now?

Hello. At that dose & with a single acute ingestion, I would not expect to see anything in the dog or older cat. But if the kitten ingested the 20 mg, then you may see symptoms of serotonin syndrome. This could include vomiting & diarrhea, & neurological signs such as ataxia or incoordination while walking, agitation, tremors, mild seizures, vocalization, disorientation, or even sedation & lethargy. You could take the smallest cat to your veterinarian for possible decontamination, or just keep a close watch on everyone for any concerning signs I have mentioned. If everyone does well over the next 12 hours, then you should have no worries. Thanks for using Petco Pet Education Center, formerly Petcoach.

The hydroxyzine is an approved medication in dogs and his normal dose would be 50 mg twice a day. You are unlikely to notice any side effects from that tablet. However cymbalta is not used in dogs but his toxic dose for his weight is around 300-400 mg. The side effects of that medication include vomiting, disorientation, lethargy and tremors. If it has been under an hour you can induce vomiting and see if he throws anything up so it won't be absorbed. If it is longer than hour you can watch for those symptoms.

0.125mg/lb (0.25mg/kg approx) is the recommended upper dose so some severe and possibly life threatening sedation could potentially occur. I would recommend getting them to an emergency vet for supportive treatment and monitoring until they can clear the drug out of their system; iv fluids, maintaining body temperature and possibly the administration of an antidote may be required

The intoxication depends on the dosage ingested. By the sound of it, if they ingested them they would have shown signs by now especially regarding the Venlafaxine. You can find clinical signs you should notice and relative treatment here at this link http://www.petpoisonhelpline.com/poison/effexor/ I would recommend to take them to your veterinarian as soon as possible, earlier than three hours (emergency clinic) if you notice anything compatible with the signs listed in that link. No home remedies are available unfortunately.

Mirtazapine does have a side effect of drowsiness or sedation in pets. It is commonly used in cats as an appetite stimulant. 30mg would be 4 times higher than I normally use, and this overdosage can cause: 57% vocalizing, 38% agitated, 23% vomiting, 21% tachycardic, 15% ataxic and 11% lethargic. The symptoms can last a little longer than 72 hours. As long as Dolly is still eating and drinking normally, I would continue to watch her. If the she is still not completely normal in a day or two, she may need a checkup with a vet.

This is about a 5-fold overdose for your cat. Please take her to your vet right away. He will have to make your cat regurgitate the capsule. At overdose with 20 mg/kg Clomicalm (5 times the maximum therapeutic dose), bradycardia and arrhythmias (atrioventricular node block and ventricular escape beats) were observed approximately 12 hours after dosing in dogs. Cats are usually more sensitive to medications, so this may be more toxic. Please take your kitty to your vet now.

It could potentially cause serious toxicity. Blackie should be seen by your veterinarian or at the nearest veterinary ER. If the ingestion was less than 2 hours ago, vomiting can be induced via injection. Activated charcoal may be given after to further decrease absorption. Kidney function should be monitored to confirm no damage has been done.
