When your pet is in pain, it is natural to want to give them something for immediate relief, like Tylenol, but is it safe?

In this post, I’ll explore the potential risks and side effects of Tylenol for pets and what you should do if your dog or cat has ingested this common pain reliever.

Key Takeaways:

  • Tylenol is not a safe option for pets and no amount of acetaminophen should be ingested by cats or dogs as it is highly toxic.
  • Pets suffering from Tylenol poisoning tend to display symptoms such as vomiting, stomach pain, lethargy, and rapid breathing. These tend to differ between cats and dogs, with cats being more sensitive to acetaminophen.
  • If your pet has ingested Tylenol (of any amount) they should be taken to your nearest emergency veterinary clinic immediately.

Is Tylenol (Acetaminophen) Safe for Pets?

No, Tylenol (acetaminophen) is not safe for pets. It can be highly toxic to both cats and dogs. Even small doses of Tylenol can be harmful.

Why is Tylenol Toxic for Pets?

Tylenol is toxic to cats and dogs because of their reduced ability to metabolize the medication. Improper metabolism leads to toxic build up of acetaminophen in their bodies.

Tylenol (Acetaminophen) can cause liver damage in pets and decrease the red blood cell's ability to carry oxygen, which can be very dangerous.

Cats are more sensitive to acetaminophen than dogs and even a small amount can lead to toxicity. Cats are likely to develop red blood cell changes as a result of ingesting Tylenol, while dogs are more likely to suffer from liver damage.

Signs of Acetaminophen Poisoning in Pets

Recognizing the signs of acetaminophen (Tylenol) poisoning in pets is crucial for their health and safety.

Both cats and dogs will exhibit symptoms such as vomiting, lethargy, and rapid breathing when they ingest Tylenol. However, symptoms can vary between dogs and cats, as they metabolize the drug differently.

Tylenol Poisoning in Dogs:

  • Lethargy or Weakness: Dogs may also appear less active.
  • Vomiting and Diarrhea: Gastrointestinal upset is a common symptom.
  • Abdominal Pain: Your dog may show signs of discomfort around the belly area.
  • Jaundice: Yellowing of the eyes, gums, or skin, indicating liver damage.
  • Changes in Urine Color: Dark or brown-colored urine.
  • Rapid Breathing: Difficulty breathing or increased respiratory rate.

Acetaminophen Toxicity in Cats:

  • Lethargy or Weakness: Cats may appear unusually tired or weak.
  • Difficulty Breathing: Look for labored or rapid breathing.
  • Brownish or Bluish Gums: This indicates a decrease in oxygen in the blood.
  • Swelling: Particularly of the face or paws.
  • Vomiting: An early sign of distress.
  • Hypothermia: Lower than normal body temperature.

📒 Note: If you notice any of these signs, your pet should be seen by a veterinarian immediately.
