Overview of Diazepam

Diazepam is a sedative to relieve stress on the brain of dogs and cats. There is a lot of uncertainty on how valium works in dogs and cats, but the general thought is that it reduces the levels of serotonin and acetylcholine.

The Food and Drug Administration (FDA) and the Drug Enforcement Agency (DEA) in the United States regulate valium. The restrictions may also apply in other countries. The regulation of Valium is because of its abuse potential, and thus you can obtain a prescription from a veterinarian. 

Diazepam is under the benzodiazepine classification. Also found in this class include clonazepam, midazolam, alprazolam, and clerozepate

Cats may suffer acute liver problems. Examine your cats more carefully before using the drug to avoid long term or recurrent cases of liver problems.

Dosage Information for Dogs and Cats

Medication should not be given without the consultation from a veterinarian

A typical dog’s dosage is 0.25 to 1mg per pound and for cats is 0.25 to 0.5mg per pound. The dosage is given through drips (intravenous) or as needed every six hours.

Diazepam can be administered through the rectum as a liquid solution or the nasal cavity for a dog that is convulsing. This dosage range from 0.5 to 1mg per pound. The diazepam solution is used to carry out the injection. It is normal for a vet to give you a dose of diazepam solution to use when the dog gets uncontrollable seizures.

Cats get a dose of diazepam within the ranges of 1 to 4mg orally every 12 to 24 hours.

The duration of using the drugs depends on the animal’s response to medication and if any side effects are slowing down the treatment. Follow the veterinarian instructions until you finish the prescription.

Administering Diazepam Pill at Home

Unlike dogs, cats are the most difficult pets to pill. A dog can have the pill mixed with its dog food, and it will ingest the tablet as it feeds. Cats cannot be tricked into teasing it with a pill held onto your hand to eat, the available option is to use your fingers, or a pill gun to ensure the cat also gets its dose.

If you own a cooperative cat, hold her up with your arms, open the mouth using your fingers and make sure you insert the pill at the back of its throat then hold on to the mouth by stroking her throat until she swallows.  Watch out if the pill was indeed taken to avoid disappointment.

For a non-cooperative cat, wrap it in a small towel to secure her firmly in your arms and try to administer the pill. If it is an aggressive cat, use a pill gun to dispense the pill quickly. You can obtain a pill gun from the local veterinary clinic.

Something to Think About

Watch your dog or cat when administering diazepam. Ensure that they are in a safe area where they cannot fall off due to lack of coordination after the drug takes effect. The best person to advise you on the possible effects of diazepam on your cat is the vet, and you can ask for possible alternative medications if the possible side effects scare you.

  1. There’s a stray cat visiting my house who has had a thread tied so tightly around his neck when he was younger that it has cut into his flesh. Not surprisingly, he is very wary of humans and there is no chance of catching him in the short term. It is urgent that this thread be removed.

    I want to feed him enough diazepam that he will be heavily sedated as quickly as possible – I don’t want him to walk off and fall into a stupor somewhere that I can’t get to him. My house is very open and I won’t be able to trap him on a room.

    I live in a small developing country in lockdown. All three small animal vets have only injections available and with no flights in or out I doubt I’ll be able to access anything else that can be administered orally.

    Super grateful for any advice on dosage, time to take effect and duration of effect. He’ll need the wounds treated and probably an antibiotic jab too, so it would be helpful to know my time limit. Once he’s got the thread off I expect we’ll become good friends 🙂

  2. I would put out a have a heart cage with food in it. Catch him that way, then stick something through the cage to tear the thread or take him to the vet in the cage. They can handle him. I don’t think valium will knock him out fast enough.

    • Thanks for the suggestion aggy. I don’t think I’ll be able to find such a trap. But I’ve started habituating him to eat just inside the door of bedroom, which I realised could be made secure enough. When I drug him I’ll shut the door and just wait with him for however long it takes.

      So, back to my question about dosage etc. Any advice?
