My 10lb cat ate .5mg Ativan. Will she be okay or is it toxic?

You can give lorazepam as one off dose. It is not a perfect drug to treat stress in cats long term. The dose is 0.02mg to 0.1mg per kg of body weight. Starting dose should be low, so you should give your cat about 0.15mg. If you have 1mg tablets it would be about 1/7 of the tablet. Please, remember that there are safer and easier to dose medications for cats to relief stress so I would recommend you to talk to your local vets and get one of the medication that is licensed to be used in cats.

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.

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question. Oh no, poor Luna. Even if she only ingested 6mg, that's double the highest recommended dose for a cat her weight. Too much clonazepam can lower the blood pressure, leading to weakness or collapse. In a senior cat, low blood pressure can be very serious. I'm not sure why you have no way of getting her to a vet, but she does need to see one immediately to make sure everything is ok. I would see if you could have a friend or family member take you into the vet, or call a cab or Uber to have her seen now. Best of luck.

Animals can show signs of toxicity after ingesting 1.5 mg per kilogram of body weight and Hunter may have ingested over 7 mg per kg. I would be concerned about the potential for serotonin syndrome secondary to this medication. It could cause agitation, high heart rate or blood pressure, muscle tremors or seizures. I would recommend seeing an emergency veterinarian to discuss treatment. Attempting to induce vomiting might be recommended if he ate the pill recently, but it can be difficult to get cats to vomit. Otherwise the recommended treatment would probably be IV fluids and monitoring in the hospital.

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

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.

In cats, the dose is 0.125 to 0.25 mg per cat as needed up to every 12 hours. This medicine should be used only if strictly recommend and/or supervised by a veterinarian.
