Dog Vitamin K in fridge: Is it still effective for mouse poison?

Your assumption is correct, under 2 hours vomiting MUST always be induce when a toxic material has been or is suspected of being ingested. The problem with mouse/rat poisoning is that it is quantity dependent, if he ingested too much, no amount of vitamin K will save him unfortunately, and it is still too soon to know as some of those poisoning have a delayed action mechanism which means they can start working 2-3 weeks after ingestion. You must continue the vitamin K at home for at least 3 weeks and hope for the best.

Vitamin K1 is usually dosed at 2.5 mg/kg twice daily as an antidote for anticoagulant rodenticide and giving with a fatty meal is recommended. I would definitely check in with the vet who instructed you to give the medication before starting however - that dose works out to 34 mg for a 30 lb dog, and that would be a lot of 100 mcg tablets to give. There is a veterinary version of Vitamin K1 that comes in 25 and 50 mg tablets that would work better. You could consider calling the Pet Poison Helpline to see what they would recommend as well - they might have more information about medications: petpoisonhelpline.com

It needs to be Vitamin K1; not Vitamin K3 or any others. It can hurt him if you don't give him the right dose as Vitamin K is stored in fat and can build up in the tissues. If too much is given, it can cause a toxicity. What poison do you think he ate? Vitamin K is only indicated if an anticoagulant poison was ingested.

If your dog ate anti-coagulant rat poison, it makes no sense to wait to give him the Vit. K1. Vit. K1 will only work if your dog ate rat poison that is an anticoagulant. You should contact your vet's office for a recommendation as we are not in a position legally to give out dosages. In order to do legally so we would have to have a patient-veterinarian-owner relationship with you. Your veterinarian also knows your dog and the potential risks for your dog receiving this medication. If your dog ate Bromethalin rat poison, Vit K1 will not work. It makes the brain swell and is moderately to severely toxic. There is no antidote, only supportive care, such as inducing emesis (vomiting, to remove as much poison as possible), charcoal (to hopefully neutralize some of the poison, iv fluids and medication to reduce the cerebral edema (brain swelling). As with many poisons, the dose is important. You will need to monitor your dog for a few days for incoordination (ataxia), tremors, seizures, and paralysis. If your dog is not showing any of those signs 24 hrs after ingestion, there is a good chance that he will not have eaten a detrimental amount and therefore may not need treatment.

It would really depend on the type of poison and how much Eric could have gotten. At the very least, I would recommend that he be seen by a vet for baseline blood work and coagulation times and to start Vitamin K in case it was an anticoagulant rodenticide. If it was a below-toxic ingestion, the Vitamin K is still safe to be given.

Mila should be seen by a veterinarian immediately. This product is an anti-coagulant poison that inhibits normal blood clotting and leads to internal bleeding. Fortunately, there is an effective antidote (Vitamin K) but it's important to make sure you minimize the amount of poison Mila absorbs, and get her started on the antidote. Depending on the timing of the ingestion, your vet may make Mila vomit, and may give her something to minimize absorption, or they may recommend testing her current blood clotting ability. Then they will likely start her on a regimen of Vitamin K. Hope this helps! https://www.petpoisonhelpline.com/poison/long-acting-anticoagulants-mouse-and-rat-poison/

I am sorry to hear about your worry with Charley! It sounds like luckily she is in the clear! If she wasn't showing any signs of toxicity and started vitamin K right away, then most cases would do just fine. Also, it sounds like she didn't ingest enough to cause toxic effects if the company is correct. If you want to feel even more certain (in terms of amount ingested) you can call Animal Poison Control if you know the exact brand/concentration of the bait she ingested, then they can calculate the toxic dose needed to cause symptoms. There is a fee for their service. The number is (888) 426-4435. IT sounds, however, like you have nothing to worry about!
