Sudafed Toxicity in Pets 

Are you concerned about your pet’s health? When it comes to medications, there are hundreds to choose from, but you may be unsure of which ones are safe for your beloved companion. One drug that raises alarm bells is Sudafed. Sudafed is a common decongestant used to alleviate difficult breathing in humans. Unfortunately, this medication poses certain toxic dangers if ingested by pets. Read below to learn more about Sudafed toxicity in pets and why you must keep it far away from your furry friends! 

Dangers of Sudafed 

Sudafed, also known as pseudoephedrine, is a common over-the-counter decongestant used by humans to alleviate nasal congestion and sinus pressure. While it can effectively relieve symptoms in humans, Sudafed can be extremely toxic and even fatal to pets if ingested. Pets, such as dogs and cats, are more sensitive to pseudoephedrine than humans are, and the consequences of ingestion can be severe. The drug acts as a stimulant on the nervous system, leading to an increase in heart rate, blood pressure, and body temperature. If a pet accidentally ingests Sudafed, it is crucial to seek immediate veterinary attention. 

Sudafed Poisoning Symptoms 

If a dog or cat accidentally ingests Sudafed, they can experience adverse reactions. Potential signs of Sudafed toxicity include: 

  • Vomiting 
  • Dilated pupils 
  • Hypertension 
  • Abnormal heart rhythms 
  • Tremors 
  • Seizures 


If your pet accidentally ingests Sudafed, you must seek immediate veterinary intervention by contacting your veterinarian and Pet Poison Helpline at (855) 764-7661. Transport your pet to the veterinary clinic right away so they can receive treatment. Treatment may include inducing vomiting and administering activated charcoal to absorb any remaining toxins in the stomach. Depending on the severity of the symptoms, additional treatment may be necessary, including IV fluids, medication to control seizures, or other supportive measures. To avoid dangerous situations such as Sudafed poisoning, make sure to secure all medications away from your pet’s reach.
