What Is Cerenia® for Dogs?
Maropitant (Cerenia®)is FDA-approved for use in dogs to help prevent and treat vomiting caused by motion sickness. Cerenia®is also used to treat acute nausea and vomiting in dogs and can alleviate nausea associated with chemotherapy. The injectable formulation of Cerenia® is FDA-approved for use in both dogs and cats for relief of vomiting, but at the time of this publication, the tablets had only been approved by the FDA for use in dogs.
Maropitant is available in oral tablet formulation, including the brand name Cerenia® and as generic maropitant. Veterinarians may prescribe the tablets as a treatment for vomiting in an extra-label manner. The term extra-label or off-label use means that a medication can be used in a way or in a particular species that is not specified on the medication label. While veterinarians often prescribe medications for extra-label uses, your veterinarian will determine whether this medication is right for your dog.
In certain circ*mstances, your vet may recommend a compounded formulation of maropitant. Compounded medications are prescribed if there’s a specific reason your pet’s health can’t be managed by an FDA-approved drug, such as if your pet has trouble taking pills in capsule form, the dosage strength is not commercially available, or the pet is allergic to an ingredient in the FDA-approved medication.
Compounded medications are not FDA-approved. They are created by either a veterinarian or a licensed pharmacist to best suit a patient’s particular needs. You can learn more about compounded medications here. Your veterinarian will determine whether a compounded medication is right for your

The safe use of injectable Cerenia® had not yet been tested in dogs or cats with toxin ingestion or gastrointestinal obstruction at the time of publication. The safe use of Cerenia® (maropitant) had not yet been tested in dogs or cats who are breeding, pregnant, or nursing at the time of publication.
Giving Cerenia® with certain medications can result in health risks to your pet, so it is important to discuss your pet’s medical conditions and medications, including vitamins and supplements, with your veterinarian.
How Cerenia® Works in Dogs
