Cerenia is a commonly prescribed medication for dogs and cats that suffer from motion sickness or vomiting caused by various conditions. While it is generally considered safe and effective when used as directed, some pet owners have raised concerns about its potential adverse effects.

In this comprehensive blog post, we will explore the controversy surrounding Cerenia and address the question, “How does Cerenia kill a dog?” to uncover the truth behind this topic.

Understanding Cerenia and its uses

Cerenia, also known by its generic name maropitant, is an FDA-approved medication used primarily to treat and prevent vomiting and motion sickness in dogs and cats. It belongs to a class of drugs known as neurokinin-1 (NK-1) receptor antagonists, which work by blocking certain neurotransmitters in the brain to prevent vomiting signals.

Cerenia is commonly prescribed by veterinarians for dogs experiencing vomiting due to various causes, such as car rides, post-surgery nausea, chemotherapy-induced vomiting, or gastrointestinal disorders. Pet owners often wonder, “How does Cerenia kill a dog?” but it’s important to understand that this medication is designed to provide relief and improve a dog’s quality of life.

How does Cerenia kill a dog?

The internet is rife with misconceptions and alarming claims about Cerenia’s potential risks, leading to concerns among dog owners. However, it is essential to separate fact from fiction and understand that Cerenia is generally considered safe when prescribed and administered correctly.

The question remains, “How does Cerenia kill a dog?” To address this directly, it doesn’t. There is no scientific evidence to suggest that Cerenia is lethal when used appropriately. Like any medication, Cerenia can cause side effects, but they are typically mild and infrequent.

Cerenia works by targeting specific receptors in the brain to prevent vomiting, and it does not typically cause harm or pose a danger to dogs when used according to a veterinarian’s guidance.

Potential side effects of Cerenia

Now we’ve debunked the controversial question “How does Cerenia kill a dog?”, let’s discuss potential side effects. While Cerenia is generally safe for most dogs, it is important to understand that all medications carry some degree of risk. Some dogs may experience side effects when taking Cerenia, while others won’t experience any.

As pet owners, being aware of these potential side effects is crucial. However, remember that severe side effects are rare, and the benefits of Cerenia usually outweigh the risks, especially when it provides relief from motion sickness and vomiting.

Common side effects of Cerenia include:

  1. Mild drowsiness or lethargy
  2. Diarrhea
  3. Loss of appetite
  4. Drooling

You should always monitor your dog for side effects and you should consult your veterinarian if they persist or worsen. In rare cases, some dogs may experience more severe allergic reactions, which should be addressed immediately by a veterinarian.


The risk of overdose is low. DEFRA (Department for Environment, Food and Rural Affairs) state that: “Apart from transient reactions at the injection site following subcutaneous administration, Cerenia solution for injection was well tolerated in dogs and young cats injected daily with up to 5 mg/kg (5 times the recommended dose) for 15 consecutive days (3-times the recommended duration of administration). No data have been presented on overdoses in adult cats.

Safe usage and precautions

The safety of the Cerenia has not been established in dogs less than 8 weeks of age, or in pregnant or lactating dogs. It is metabolised in the liver and therefore should be used with caution in patients with hepatic disease. Cerenia should also be used with caution in animals suffering from or with predisposition for cardiac diseases.

Always observe the following precautions when administering Cerenia:

  1. Always administer Cerenia as prescribed by your veterinarian, and never give it without professional advice. This way, you can ensure your dog receives the correct dosage and schedule appropriate for their condition.
  2. Provide your veterinarian with a complete medical history of your dog, including any existing health conditions or medications being taken. This information helps your veterinarian make informed decisions and tailor the treatment plan to your dog’s individual needs.
  3. Report any concerning side effects to your veterinarian promptly. While mild side effects may occur and are usually not cause for alarm, notifying your veterinarian allows them to assess the situation and make necessary adjustments if needed.

Cerenia is specifically designed for dogs and cats and should never be given to other animals or humans. Ensuring that medications are used as intended and under veterinary supervision is a fundamental aspect of responsible pet ownership.

Consult your Veterinarian

If your dog has pre-existing medical conditions, or you have other concerns about using Cerenia for your dog, it is best to discuss them openly with your veterinarian. A professional veterinary consultation will provide clarity and peace of mind regarding the appropriate usage and potential risks of Cerenia for your dog.

Your veterinarian is your most reliable source of information and guidance when it comes to your dog’s health and well-being. They have the expertise to address your concerns and ensure that your dog receives the best possible care.

Addressing the need for more research

As with any medication, there is always a need for ongoing research and monitoring of its effects. While current scientific evidence supports the safety of Cerenia, continued vigilance is necessary to ensure that any potential risks are promptly identified and addressed.

Veterinarians and researchers play a vital role in studying the long-term effects of medications like Cerenia on canine health. By collaborating with pet owners and keeping an open line of communication, they can collect valuable data and further improve our understanding of the drug’s safety profile.

Promoting responsible pet ownership

In the context of the Cerenia controversy, responsible pet ownership remains paramount. Ensuring that your dog receives regular veterinary check-ups, adheres to a balanced diet, and maintains a healthy lifestyle is crucial for their overall well-being.

Always follow your veterinarian’s advice diligently, including administering medications as prescribed and being attentive to any changes in your dog’s behavior or health.


In conclusion, the question, “How does Cerenia kill a dog?” has sparked controversy and confusion among dog owners. However, it is crucial to understand that Cerenia is widely used and is a safe and effective medication when prescribed and used correctly. While side effects may occur, they are typically mild and uncommon.

Pet owners should recognize the importance of responsible pet ownership and open communication with their veterinarians. By adhering to the prescribed guidelines and maintaining vigilant observation of their dog’s well-being, they can ensure that Cerenia provides the intended relief from motion sickness or vomiting, improving their dog’s quality of life and overall health.

Furthermore, supporting ongoing research and maintaining a proactive approach to pet care will contribute to the continued safety and well-being of our beloved canine companions. Together, we can ensure that our furry friends receive the best care possible and lead happy, healthy lives.
