• We gave our dog his first dose of Triflexis this past Friday afternoon but threw up around 1030am Saturday morning due to car sickness. Does this mean that the Triflexis is ineffective and I need to give him another dose or is he ok?

    Hi Jade,

    I recommend that you call and talk to your veterinarian about this question. In most cases the Trifexis will still be effective if the vomiting occurs after 2 hours if giving the medication. However, this can depend on the individual dog and if pieces of the medication were seen in the vomit. Your vet knows your pet’s medical history so they can give you the best advice on this.
