Cerenia® Injection for Dogs and Cats

Cerenia® Injection is a veterinary antiemetic for dogs and cats. It helps prevent and treat acute vomiting. This page explains usage, safety, and access with US delivery from Canada, including options without insurance.

What Cerenia Is and How It Works

This treatment contains maropitant citrate, an NK1 receptor antagonist. It blocks substance P in central and peripheral pathways to help control vomiting. Maropitant Citrate Injection 10 mg/mL is used by veterinarians when pets cannot keep oral medicines down or when rapid effect is needed.

The injection can be given subcutaneously or by slow intravenous administration in clinic settings. It may be used for acute vomiting from a variety of causes and before certain chemotherapy sessions in dogs. The prescriber determines if this therapy is appropriate after evaluation.

Who It’s For

Cerenia injection for dogs is indicated to prevent and treat acute vomiting in appropriate-aged patients as per labeling. It is also labeled for cats to treat acute vomiting when your veterinarian deems it suitable. Puppies and kittens below labeled age thresholds should not receive this therapy.

When vomiting relates to emetogenic chemotherapy, veterinarians may administer the injection before agents such as Vincristine. If pain or inflammation contributes to gastric upset around procedures, your prescriber may also address those factors with options like Rimadyl Injectable. Gastrointestinal parasites can also trigger vomiting; see our overview of deworming in Tapeworm Treatment.

Dosage and Usage

The injection is typically administered once daily on a weight-based schedule, for several days as directed. Routes include subcutaneous administration or slow intravenous use in a veterinary setting. Cerenia injection dosage for cats and for dogs follows the approved label; your veterinarian will select the route, dose, and duration.

For vomiting associated with chemotherapy in dogs, a dose may be given before the antineoplastic session. Do not adjust or repeat injections unless instructed by the prescriber. Report persistent vomiting, blood, or suspected foreign body promptly.

Strengths and Forms

Cerenia injectable solution 10 mg/mL is commonly supplied in a multidose 20 mL vial. Availability can vary by pharmacy and market. The prescriber’s directions and the product label govern each use.

Missed Dose and Timing

If an in-clinic dose is missed, contact the clinic to reschedule. For any at-home administration plan, follow the timing instructions provided by your veterinarian. Do not double an injection to make up a missed dose. If your pet vomits shortly after receiving the injection, call the clinic for guidance.

Storage and Travel Basics

Store the vial at controlled room temperature per the product label. Keep the bottle upright, secure the cap, and protect it from heat and direct light. Do not freeze. Keep all medicines out of reach of children and animals. After first puncture, follow the label’s in-use time guidance.

For travel, carry the vial in original packaging with the prescription label. Pack it to prevent breakage and temperature extremes. Ask your veterinarian for a travel letter if flying. Place supplies in a carry-on bag where feasible, and avoid leaving the medicine in hot cars.

Benefits

This therapy helps control vomiting when oral tablets are not practical. It can be used before chemotherapy sessions to reduce vomiting risk in dogs. An injectable route allows reliable administration when a pet is actively nauseated.

Maropitant injection for dogs and cats targets a key pathway in the vomiting reflex, so it may help across many causes of nausea. The treatment can be combined with fluids, gastroprotectants, and diet adjustments as your prescriber advises.

Side Effects and Safety

• Injection-site pain or swelling
• Diarrhea or loose stool
• Drooling or lip licking
• Decreased appetite
• Lethargy

Serious but uncommon reactions can include allergic responses, unusual bleeding, or collapse. Pets with liver disease may require closer monitoring because the drug is metabolized hepatically. Safety in pregnant or nursing animals has not been established. Seek urgent veterinary care for signs of severe reaction or ongoing vomiting with dehydration.

Drug Interactions and Cautions

Maropitant is metabolized by hepatic enzymes. Your prescriber may use caution with strong enzyme inhibitors or inducers. Report all medicines, supplements, and preventives in use. Some antibiotics and pain medicines can contribute to gastrointestinal signs; see our Antibiotic Guide and follow veterinary advice.

Use carefully in very young animals, those with significant liver impairment, or pets with low blood pressure. This medicine is not a substitute for diagnosing the underlying cause of vomiting.

What to Expect Over Time

After administration, many pets show reduced frequency of vomiting as the underlying problem is addressed. Your veterinarian may pair this therapy with fluids, diet modification, or other supportive care. If vomiting persists, additional diagnostics may be needed. Adherence to the plan and prompt follow-up help support recovery.

Compare With Alternatives

Some pets may transition to oral therapy once vomiting subsides. For post-operative discomfort or inflammation that can worsen nausea, a prescriber may consider Onsior Solution for cats as clinically appropriate. For mucosal protection in gastritis or suspected ulceration, your veterinarian may recommend Sucralfate as an adjunct.

Patient Suitability and Cost-Saving Tips

This therapy may suit dogs and cats that meet the labeled age and health criteria. Pets with liver disease or very young animals may require different approaches. Ask your clinic about multi-day treatment plans, coordinated refills, and combining orders to reduce per-parcel fees. Scheduling follow-ups avoids urgent visits that can increase costs.

If your pet receives other injectables, such as Furosemide Injection, consider aligning deliveries so supplies arrive together. Keep reminders for reorders, and store medicines safely to prevent waste.
