Usage

This medication can be given with or without food; however, giving with food may help prevent gastrointestinal side effects.

If your pet vomits or appears unwell after receiving a dose on an empty stomach, give future doses with food or a small treat. If vomiting continues, contact your veterinarian.

Administer the complete course of the medication as prescribed, even if your pet's condition has improved. Failure to administer the entire course of treatment may cause recurrence or worsening of the infection. Contact your veterinarian ahead of time if your pet needs a refill.

Missed doses

Administer 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 two doses at once.

Storage

Store in a cool, dry place at a controlled room temperature (68 to 77°F, excursions permitted between 59 and 86°F). Keep in a tight, light-resistant container and out of the reach of children and pets. Store away from heat and direct sunlight. Do not store in the bathroom, near the kitchen sink, or in damp places. The medicine may break down if exposed to heat or moisture.

Side effects

The most common side effects of this medication are vomiting, diarrhea, decreased appetite, and lowered energy level/lethargy. These symptoms may improve over the course of treatment.

Contact your veterinarian immediately if your pet experiences severe vomiting/diarrhea, complete loss of appetite, or if you notice a severe rash/itching.

Notify your veterinarian if your pet experiences any of the effects described above, or if you notice any other side effects that are persistent or troublesome.

If you notice anything unusual, please consult your veterinarian.
