Side Effects for Cerenia in Dogs

By Jane Meggitt

If your dog suffers from motion sickness during car rides, maropitant citrate, marketed under brand name Cerenia, can prevent the nausea and subsequent vomiting. Your veterinarian also might prescribe Cerenia for other types of vomiting. The drug can have side effects, but you and your vet must decide if they outweigh the anti-vomiting benefits.

Cerenia Side Effects

Cerenia is generally well-tolerated by dogs, with few side effects. Some dogs might eat less while on the medication, thus losing weight, but usually regain their appetite once off the drug. Other side effects can include diarrhea, hypersalivation -- excessive drooling -- and lethargy.

Precautions and Contraindications

Dogs under the age of 4 months should not receive Cerenia. Pregnant or lactating dogs should not receive the drug. Cerenia is contraindicated in canines with liver dysfunction. Tell your vet about all medications and supplements your dog receives. Cerenia should not be given in conjunction with certain nonsteroidal anti-inflammatory drugs, or with some medications for seizure prevention or heart disease.
