Paracetamol is a very popular painkiller in humans, however it can be toxic or fatal in small animals. Dogs are less sensitive to paracetamol than cats. A 20kg dog would need to ingest over seven 500mg tablets in order to suffer toxic effects. In cats, one 250mg paracetamol tablet could be fatal.
Should your vet prescribe paracetamol for your dog, it's likely that it will be a dosage of 10mg per kilogram, and should only be given once a day for one or two days.
Pain Relief for Dogs
The best of a bad lot is paracetamol, sold as Panadol, Calpol or Tylenol (called acetaminophen in the US). It is sometimes used by vets at a dose of 10 mg/kg twice daily.
Ibuprofen (Nurofen) and naproxen are common and effective medications used to treat inflammation and pain in humans, but they should not be given to pets. These drugs can be toxic (poisonous) to dogs and cats, although cats are much more susceptible to this toxicity than dogs.
Paracetamol is not registered for use for dogs in Australia, meaning that it can only be administered to the strictest of guidelines. You should never give your dog paracetamol unless under strict instructions by your veterinarian to do so.
Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used to control pain and inflammation in dogs. NSAIDs help many dogs lead more comfortable lives, but these drugs should be used carefully because they all can cause side effects, some of which can be serious.
Many pain medications considered safe for people can be toxic or even fatal for dogs. Never give your dog aspirin, ibuprofen (Advil), acetaminophen (Tylenol), or any other medication designed for humans without first consulting your vet.
Ibuprofen is toxic to dogs and you should never give it to your pup. Just three to six ibuprofen capsules can be deadly for dogs, so keep the medicine in a safe place. There are canine-specific pain relievers that you can get from your vet or try natural options.
The short answer is NO. You should never attempt to treat your pets with human medication, precautions should be taken to keep household medications out reach of your pet to avoid a potentially harmful or fatal reaction.
A mild case of paracetamol poisoning can give your dog an upset stomach, and they may appear to be tired. Other symptoms can include laboured breathing, swelling on the face, neck or limbs, gums turning brownish-grey and jaundice. More serious cases can include signs of staggering, vomiting and restlessness.
If your pet has ingested paracetamol, contact your veterinarian immediately and take your pet to the veterinarian as soon as possible. Do not induce vomiting unless your vet instructs you to.
There are no readily available OTC pain meds for dogs.
Even at very small doses, they can cause life-threatening gastrointestinal (GI) ulcers, liver failure, and/or kidney failure. Lethal effects of these medications can occur very quickly, meaning that even with treatment, pets can die from eating only one dose.
Glucosamine and chondroitin are two common joint supplement ingredients that are used in both humans and dogs. These supplements work by reducing inflammation, promoting healing, and increasing water retention in the cartilage, which provides more cushioning for the joint.
Nonsteroidal anti-inflammatory drugs (NSAIDs) play a major role in controlling dog joint pain and inflammation. Prescription medications such Galliprant, Carprofen, and Meloxicam are the safest options for controlling pain and inflammation compared to over-the-counter, non-veterinary products.
When your dog is unwell or has a painful injury, you may be tempted to give them human painkillers such as paracetamol, aspirin, codeine or ibuprofen. However, it is imperative dog owners do not try to administer pain relief to their pet without first consulting a vet.
Dogs can safely consume 15mg of paracetamol per kilogram of their bodyweight, however any dose greater than this can make them sick. A single tablet of human paracetamol contains 500mg, so it certainly isn't safe for your dog to eat.
"Paracetamol is licensed in dogs as Pardale V for 5 days. The dose in Pardale V works out at 33mg of paracetamol for every kg of body weight, three times daily. The listed dose in most vet formularies is 10mg/kg twice to three times daily," Nick explains.
A commonly-used dose of Tylenol for dogs is 5 to 7 mg per pound of body weight two times daily. This should only be given under the direction and recommendation of a veterinarian. There are other safer and more effective pain medications available depending on the dog's underlying problem.
In dogs, paracetamol poisoning can occur if they ingest 75 mg per kilogram of body weight or more. Kidney and liver failure can occur from paracetamol poisoning.
Paracetamol can kill dogs even in a small overdose.
Side effects or symptoms of overdose of paracetamol in dogs can include liver damage, ulceration of the digestive tract, pale gums, vomiting, drooling, abdominal pain, breathing difficulties, or seizures.
Paracetamol comes as tablets, capsules, a syrup you swallow, a powder you add to water and a suppository. They come in different strengths: tablet – 500mg or 1g. capsule – 500mg.
