At Vets to Pets, we provide elevated, Fear Free, in-home veterinary care across Northern Virginia. Seeing pets in their own environment allows us to notice subtle signs of discomfort, stress, or illness that might be missed in a clinic setting. One common issue we treat is nausea and vomiting — and one of the most effective tools we use is Cerenia. Understanding how this medication works and when it’s appropriate can help pet parents make informed decisions about their pet’s comfort and care.

What Is Cerenia?

Cerenia (maropitant citrate) is a prescription medication used to prevent and treat vomiting in dogs and cats. It works on the nervous system to block the signals that trigger nausea, helping pets feel more comfortable. Unlike some over-the-counter remedies, Cerenia is veterinarian-approved, safe for many pets, and fast-acting.

When Is Cerenia Used?

Cerenia is commonly prescribed for:

  • Motion sickness during travel
  • Acute vomiting due to illness or ingestion of something disagreeable
  • Nausea associated with kidney or liver disease
  • Vomiting related to chemotherapy or other medical treatments

Because nausea can quickly lead to dehydration and discomfort, prompt treatment often improves recovery and quality of life.

How Cerenia Works

Cerenia targets receptors in the brain and gastrointestinal system that trigger the vomiting reflex. By blocking these signals, it prevents nausea before it escalates into vomiting. This action helps your pet maintain hydration, appetite, and comfort — essential for healing and wellbeing.

Administration and Safety

Cerenia comes in several forms, including injectable and tablet options. Dosage depends on your pet’s species, size, and condition. During in-home visits, we can administer injectable Cerenia in a calm, stress-free environment or guide you on safe at-home oral dosing if appropriate.

Most pets tolerate Cerenia very well, though mild side effects like drowsiness or temporary loss of appetite can occur. Serious reactions are rare, but it’s always important to use Cerenia under veterinary guidance.

Why In-Home Care Matters

Administering medication in a familiar environment reduces stress, making treatment more effective and improving your pet’s experience. Our Fear Free approach ensures pets feel safe and supported during administration — which is especially important for pets prone to anxiety or motion sickness.

When to Call the Vet

If your pet is vomiting frequently, showing signs of lethargy, or refusing food and water, contact your veterinarian promptly. Early intervention with medications like Cerenia can prevent complications and keep your pet comfortable.
