What is Cerenia for cats, and how does it work?

The active ingredient of Cerenia is maropitant citrate. This medicine blocks substance P - a chemical messenger involved in nausea and vomiting in a cat's nervous system. By blocking this chemical messenger, Cerenia prevents nausea and, as a result, vomiting. Cerenia does not affect your cat's digestive system.

Cerenia is a prescription medication that should be given only under the guidance of a veterinarian.

What is Cerenia used for in cats?

Cerenia for cats can be used to treat nausea and vomiting due to various causes, including the following:

  • Gastroenteritis (inflammation of the gut)

  • Pancreatitis (inflammation of the pancreas)

  • Inflammatory bowel disease

  • Eating something that doesn't agree with your cat

  • Intestinal infections

  • Cancer (can help manage the side effects of chemotherapy)

  • Surgery (can help reduce nausea associated with anesthesia)

  • Nausea due to another medication reaction

  • Kidney disease

Cerenia does not treat the cause of nausea and vomiting. But it can be used to reduce nausea and help your cat feel better, giving your veterinarian time to diagnose the underlying problem.

What is the dosage of Cerenia for cats, and how is it given?

Cerenia for cats comes in an FDA-approved injectable form that can be given intravenously or as an injection under the skin. The typical dosage of injectable Cerenia is 1 mg per kilogram of a cat's body weight. It is usually given by veterinary professionals. Injectable Cerenia works within minutes.

The tablet form of Cerenia is FDA approved only for use in dogs, but Cerenia tablets are commonly prescribed off-label for cats. Cerenia tablets are peach colored and scored with a break line. They are packaged in blister packs containing 4 tablets and come in doses of 16 mg and 24 mg.

Oral Cerenia takes 1 to 2 hours to take effect. Give the medication with a small amount of food. But Cerenia can be given on an empty stomach if your cat isn't eating.

Each dose of Cerenia is effective at reducing nausea and vomiting for about 24 hours. Cerenia is typically given once every 24 hours.

What are the common side effects of Cerenia in cats?

In general, most cats tolerate Cerenia well, and it rarely causes negative side effects. The most common side effects in cats reported to the manufacturer included:

  • Fever

  • Dehydration

  • Excessive tiredness

  • Drooling

In addition, pain and swelling at the injection site have been reported in cats. Cats may also hiss or retreat when the injection is given. Side effects are generally short lived with Cerenia, but they may last longer in cats with liver or kidney disease.

What are the most serious risks of Cerenia for cats?

Cerenia is generally safe for cats. But there have been cases of cats who develop trouble breathing and weakness after a Cerenia overdose. This is why it is important to give Cerenia under the supervision of a veterinarian and as directed on your cat's prescription.

In some situations, Cerenia may not be an appropriate medication based on the cause of your cat's nausea and vomiting. This can include:

  • Cats who are under 8 weeks of age

  • Cats who are pregnant or nursing

  • Cats who could have ingested poisons or toxic substances

  • Cats who could have an intestinal obstruction

  • Cats who have been vomiting longer than 3 days

Does Cerenia interact with any other cat medications?

Cerenia can be given with most medications. But if your cat takes any of the following medicines, check with your veterinarian before giving your cat Cerenia:

What should you do if your cat misses a dose of Cerenia?

If you miss giving your cat a dose of Cerenia, then give the next dose as soon as possible. Don't give two doses at the same time to make up for a missed dose. If you have questions, contact your cat's veterinarian for guidance.

The bottom line

Cerenia (maropitant citrate) for cats is a safe, fast-acting medication to reduce acute nausea and vomiting in cats. It's available as an injection given by your cat's veterinarian or as a tablet given to your cat by mouth. Cerenia can cause side effects, such as drooling or excessive tiredness.
