Maropitant Citrate

Why has my veterinarian prescribed this medicine?

Maropitant is a medication (technically a neurokinin receptor antagonist) that makes stimulation of the vomit center extremely difficult.  In dogs 16 weeks and older, it is used to prevent vomiting due to motion sickness and to prevent acute vomiting which may be associated with stomach and intestinal problems, infections (in particular from parvovirus), pancreatitis, and vomiting as a result of chemotherapy.

The safety of this medication has not been determined in pregnant dogs, female dogs nursing their young, dogs with stomach or instestinal obstruction and dogs that have ingested undetermined poisons.

 

How do I give this medication?

Tablets

  • Give this medication to your pet as directed by your veterinarian. READ THE LABEL CAREFULLY.
  • Give maropitant tablets 2 hours before traveling with a small amount of food such as deli slices, peanut butter or spreadable cheese. Do not give this medication wrapped in a treat that may cause stomach upset.
  • Do not give tablets with fatty foods such as hot dogs, sausages and pill pockets since these may delay the tablet from dissolving and therefore delay the effect of the medication.
  • Do not wrap tablets tightly in food or snacks since this may delay dissolution of tablets
  • Giving a small meal or snack one hour before giving the tablet will minimize the occurrence of pre-trip vomiting.

Injection

  • The injection may be administered subcutaneously (in the fat layer under the skin) once daily for up to 5 consecutive days.
  • If longer treatment is necessary, a 48 hour period without medication is necessary.

 

What do I do if I miss giving a dose?

Give the dose as soon as possible. If it is almost time for the next dose, skip the missed dose, and continue with the regular schedule. Do not give the pet two doses at once. maropitant_citrate1
