6. Uses in Dogs and Cats:

Indicated for the prevention and treatment of acute vomiting in dogs and cats. Labeled for prevention of vomiting due to motion sickness and to control vomiting secondary to chemotherapy in dogs. Cerenia has also been shown to decrease visceral pain (pain related to the internal organs).

7. How it Works:

Cerenia works in the central nervous system to inhibit Substance P, which is a key neurotransmitter (a chemical substance that is released in the nervous system) involved in vomiting.

8. Side Effects and/or Signs of Overdose:

Side effects are rare but include diarrhea and decreased appetite. Vomiting and hypersalivation may be seen if giving higher dosages, which are required to prevent motion sickness. Swelling or pain at the injection site has been seen with the administration of the injectable form.

Cerenia is well tolerated so issues with overdosage are unlikely, but may include vomiting. Acute overdosage is unlikely to cause serious clinical effects.

None currently reported
