Cerenia® Tablets for Dogs

Cerenia is a veterinary antiemetic used to prevent vomiting and motion sickness in dogs. Many pet owners use Cerenia for dogs when travel or illness causes nausea, and you can compare options and costs without insurance with US delivery from Canada. This page explains how it works, who it is for, and how to use it safely.

What Cerenia Is and How It Works

Cerenia® contains maropitant citrate, a neurokinin-1 (NK1) receptor antagonist. It works by blocking substance P in the vomiting center, which helps reduce nausea and vomiting from many causes, including travel. Maropitant citrate tablets provide a systemic effect and can be used for short courses under a veterinarian’s direction.

Who It’s For

This medicine is used in dogs to prevent acute vomiting and to help with motion sickness. It may be considered when vomiting is linked to gastroenteritis, dietary indiscretion, chemotherapy, or travel-related nausea. Dogs with known hypersensitivity to maropitant should not receive it. Use caution in dogs with liver disease, and in very young puppies, as directed by the veterinarian. Explore broader options across Dog Medications.

Dosage and Usage

Follow the veterinarian’s prescription exactly. For vomiting, the treatment is typically given once daily for a short period. For travel-related nausea, it is generally administered in advance of departure so it has time to work. Giving the tablet with a small meal may improve acceptance. Avoid repeated dosing unless instructed. If your dog has underlying illness, the prescriber may prioritize treating the cause while using this medicine for symptom control.

Strengths and Forms

The tablet form is commonly available in several strengths for dogs, often selected by weight and indication. There is also a liquid solution administered by a veterinary professional when oral dosing is not possible. The injectable form may be used in clinics for rapid onset or when a dog cannot keep tablets down. Availability can vary by pharmacy and region.

• Tablet strengths: typically 16 mg, 24 mg, 60 mg, and 160 mg.
• Clinic use: the injection is reserved for cases where oral dosing is not suitable.

Missed Dose and Timing

If the medicine is prescribed daily for vomiting, a missed dose is usually given when remembered unless it is close to the next scheduled time. Do not double dose. For motion sickness, timing matters; it should be given ahead of travel as advised on the label or by the veterinarian. If your dog vomits after receiving a dose, contact the clinic for guidance on whether to repeat or adjust future timing.

Storage and Travel Basics

Store tablets at room temperature in the original packaging and keep them dry. Protect from moisture and keep out of reach of children and other pets. When traveling, carry the labeled container and a copy of the prescription. Pack an extra day or two of medicine in case plans change. Do not leave any pet medicine in a hot car. For long trips, place doses in a secure, sealable bag within your hand luggage so you can access them before travel.

Benefits

This medicine can reduce episodes of vomiting from many common causes and can help dogs tolerate travel better. Once-daily schedules are typical for short courses, which simplifies use for caregivers. The tablet form avoids clinic visits for many dogs, and the option of in-clinic injection allows flexibility when oral dosing is not possible.

Side Effects and Safety

• Common: drooling, decreased appetite, soft stools or diarrhea, lethargy.
• Less common: trembling, hypersalivation from tablet taste, mild ataxia.
• Injection-related (clinic use): local discomfort at the site.

Serious reactions are uncommon but can include allergic responses such as facial swelling, hives, or collapse. Use caution in dogs with hepatic impairment; periodic monitoring may be advised. Bitter taste may cause drooling if a tablet is chewed. If concerning signs occur, stop the medicine and seek veterinary care.

Drug Interactions and Cautions

Tell the veterinarian about all medicines and supplements your dog receives. Interactions can occur with drugs that affect liver enzymes or those that are highly protein-bound. Sedatives and certain pain medicines may have additive effects. The prescriber may adjust therapy if antibiotics, antifungals, or seizure medicines are used at the same time.

What to Expect Over Time

When used for vomiting, improvement may be noticed after the first dose in many cases. For motion sickness, the effect depends on administering it ahead of travel. The course is often short. If vomiting persists, the veterinarian may reassess the underlying condition. Dogs with recurrent nausea may need further diagnostics or a different plan.

Compare With Alternatives

Some dogs need a non-oral option or supportive GI care. A prescriber may consider an in-clinic dose using Cerenia Injection when a dog cannot keep tablets down. If stomach lining protection is a priority, a GI coating agent such as Sucralfate may be used alongside a veterinarian’s plan. Dewormers or diet changes may be chosen when vomiting relates to parasites or food intolerance.

Pricing and Access

You can review current pricing and place an order for US delivery from Canada after your prescription is verified. Total costs vary by strength, quantity, and pharmacy inventory. If you are comparing tablet and clinic options, remember that professional fees for examinations or injections are billed separately by your veterinarian.

Availability and Substitutions

Supply can vary by strength and package size. If a specific presentation is not available, a veterinarian may recommend a different strength combination, a clinic-administered injection, or a generic maropitant option when appropriate. Pharmacies dispense only with a valid prescription, and substitutions are made in consultation with the prescriber.

Patient Suitability and Cost-Saving Tips

Good candidates include dogs with acute vomiting or travel-related nausea, as assessed by a veterinarian. Dogs with severe liver disease, very young puppies, or those with known sensitivity may need a different plan. To manage out-of-pocket costs, discuss multi-month fills when appropriate, since fewer refills can reduce separate dispensing fees. Set calendar reminders for refills before trips. Keep notes on how your dog responds to the medicine during travel, which helps the veterinarian refine dosing timing for future journeys.
