Paracetamol is a common human medication and can be bought without a prescription. In certain circumstances, it can be used in dogs. However, dogs require different doses than humans. Paracetamol can be highly toxic to dogs if they are given too high a dose.
Paracetamol, while safe for humans, can be extremely toxic for your dog (particularly if the wrong dosage is given), and can result in serious liver damage or problems with their red blood cells.
Nurofen contains an anti-inflammatory called Ibuprofen which is highly toxic to pets. Even just one or two tablets can cause vomiting, abdominal discomfort, and painful stomach ulcers. In more severe cases, the Ibuprofen can cause major damage to your pet's kidneys.
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.
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.
What NSAIDs are safe for dogs? NSAID options that are approved for use in dogs include carprofen (e.g. Rimadyl), deracoxib (e.g. Deramaxx), etodolac (e.g. Etogesic), firocoxib (e.g. Previcox), meloxicam (e.g. Metacam), robenacoxib (e.g. Onsior), and mavacoxib (e.g. Trocoxil).
FDA-approved nonsteroidal anti-inflammatory drugs offer pain relief for many dogs with osteoarthritis. These drugs also help veterinarians effectively manage pain after surgery in both dogs and cats.
The listed dose in most vet formularies is 10mg/kg twice to three times daily," Nick explains. "For a 10kg French Bulldog, for example, this would be 330mg three times daily at the top end of the dose range, down to 100mg two or three times a day."
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.
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.
However, as tempting as it may be to reach for an over-the-counter pain meds such as ibuprofen, aspirin, or acetaminophen and give it to the family dog, you must avoid them at all costs. Over-the-counter pain meds and anti-inflammatories can be very dangerous, even fatal, when used improperly in dogs.
For dogs, ibuprofen can easily exceed toxic levels. Ibuprofen has a narrow margin of safety in dogs. Signs of toxicosis can occur when as little as half a 200 mg pill is given to a 25 pound dog. The most common cause of ibuprofen toxicity is a well-meaning owner trying to alleviate pain in his dog.
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. While your vet may prescribe aspirin to help your dog when they're in pain, you should not give them the same medication you have in your cabinet. Medicines like ibuprofen and naproxen can be toxic to dogs, even in small doses.
Never attempt to relieve your dog's pain by administering over-the-counter medications, such as ibuprofen, naproxen (e.g., Aleve), acetaminophen (e.g., Tylenol), or aspirin. Human anti-inflammatories can cause life-threatening toxicities in pets, and you should give your dog only veterinarian-prescribed medications.
What are the typical signs of pain in dogs? General behaviour: Shaking, flattened ears, low posture, aggression, grumpy temperament, panting or crying, excessive licking or scratching a specific area, reluctant to play, interact or exercise, lameness (limping), stiffness after rest, loss of appetite.
Wincing, Whining or Crying
All three of these actions indicate an injury or some kind of pain your dog is experiencing. If you start to pet your dog and they shy away from your hand or whine, you know there is something wrong. Your pet might need x-rays and a full examination to determine the cause.
Some dogs remain stoically quiet when they're hurting but others, especially young dogs who have not experienced physical discomfort, may whimper and cry when they're feeling pain. Your presence may provide comfort and lead them to stop whining.
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.
In dogs, signs of acute toxicity are usually not seen unless the dosage of acetaminophen exceeds 100 mg/kg. Clinical signs of methemoglobinemia have been reported in 3 of 4 dogs at 200 mg/kg. Toxicity can be seen at lower dosages with repeated exposures. In cats, toxicity can occur with 10–40 mg/kg.
Poisoning can occur from a single exposure to a large dose or from chronic exposure to a low dose. Acetaminophen poisoning in dogs causes injury to the liver and, in high enough dosages, even liver failure. Clinical signs can include lethargy, loss of appetite, belly pain, and jaundice.
