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.

Side effects may include upset stomach, which may lead to diarrhea; other side effects include possible fluid retention, stomach ulceration, and lesions or ulcers in the mouth. Contact your veterinarian if these symptoms appear to be troublesome for your horse. Contact your veterinarian if the following symptoms are noted: changes in appetite, changes in drinking habits and urination frequency, seizures, coma, hyperventilation, persistent nausea and/or diarrhea, severe hypotension, depression, and weakness.

Contact your veterinarian if your horse experiences any unusual reactions when different medications are given together.
