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 2 doses at once.

Rare but serious side effects include abnormal heart rhythms and low blood pressure, which may cause fainting/collapse or severe lethargy. These symptoms may go away during treatment. If these symptoms continue, contact your veterinarian.
